Feds Arrest Alleged Top Silk Road Drug Seller

October 7, 2013

Federal authorities last week arrested a Washington state man accused of being one of the most active and sought-after drug dealers on the online black market known as the “Silk Road.” Meanwhile, new details about the recent coordinated takedown of the Silk Road became public, as other former buyers and sellers on the fraud bazaar pondered who might be next and whether competing online drug markets will move in to fill the void.

A complaint unsealed Oct. 2 by the U.S. District Court for the Western District of Washington at Seattle alleges that Steven Lloyd Sadler, 40, of Bellevue, Wash., used the nickname “NOD” on the Silk Road, and was among the “top one percent of sellers” on the Silk Road, selling high-quality cocaine, heroin and methamphetamine in small, individual-use amounts to hundreds of buyers around the world.

Investigators with the FBI and U.S. Post Office inspectors say they tracked dozens of packages containing drugs allegedly shipped by Sadler and a woman who was living with him at the time of his arrest. Authorities tied Sadler to the Silk Road after intercepting a package of cocaine and heroin destined for an Alaskan resident. That resident agreed to cooperate with authorities in the hopes of reducing his own sentence, and said he’d purchased the drugs from NOD via the Silk Road.

Agents in Seattle sought and were granted permission to place GPS tracking devices on Sadler’s car and that of his roommate, Jenna White, also charged in this case. Investigators allege that the tracking showed the two traveled to at least 38 post offices in the Seattle area during the surveillance period.

Interestingly, the investigators used the feedback on NOD’s Silk Road seller profile to get a sense of the volume of drugs he sold. Much like eBay sellers, merchants on the Silk Road are evaluated by previous buyers, who are encouraged to leave feedback about the quality of the seller’s goods and services. According to the government, NOD had 1,400 reviews for individual sales/purchases of small amounts of drugs, including: 2,269.5 grams of cocaine, 593 grams of heroin and 105 grams of meth. The complaint notes that these amounts don’t count sales going back more than five months prior to the investigation, when NOD first created his Silk Road vendor account.

Cryptome has published a copy of the complaint (PDF) against Sadler. A copy of Sadler’s case docket is here. NOD’s reputation on the Silk Road also was discussed for several months on this Reddit thread.

Many readers of last week’s story on the Silk Road takedown have been asking what is known about the locations of the Silk Road servers that were copied by the FBI. It’s still unclear how agents gained access to those servers, but a civil forfeiture complaint released by the Justice Department shows that they were aware of five, geographically dispersed servers that were supporting the Silk Road, either by directly hosting the site and/or hosting the Bitcoin wallets that the Silk Road maintains for buyers and sellers.

Two of those servers were located in Iceland, one in Latvia, another in Romania, and apparently one in the United States. See the map above.

Adobe To Announce Source Code, Customer Data Breach

October 3, 2013

Adobe Systems Inc. is expected to announce today that hackers broke into its network and stole source code for an as-yet undetermined number of software titles, including its ColdFusion Web application platform, and possibly its Acrobat family of products. The company said hackers also accessed nearly three million customer credit card records, and stole login data for an undetermined number of Adobe user accounts.

KrebsOnSecurity first became aware of the source code leak roughly one week ago, when this author — working in conjunction with fellow researcher Alex Holden, CISO of Hold Security LLC — discovered a massive 40 GB source code trove stashed on a server used by the same cyber criminals believed to have hacked into major data aggregators earlier this year, including LexisNexis, Dun & Bradstreet and Kroll. The hacking team’s server contained huge repositories of uncompiled and compiled code that appeared to be source code for ColdFusion and Adobe Acrobat.

Shortly after that discovery, KrebsOnSecurity shared several screen shots of the code repositories with Adobe. Today, Adobe responded with confirmation that it has been working on an investigation into a potentially broad-ranging breach into its networks since Sept. 17, 2013.

In an interview with this publication earlier today, Adobe confirmed that the company believes that hackers accessed a source code repository sometime in mid-August 2013, after breaking into a portion of Adobe’s network that handled credit card transactions for customers. Adobe believes the attackers stole credit card and other data on approximately 2.9 million customers, and that the bad guys also accessed an as-yet-undetermined number of user names and passwords that customers use to access various parts of the Adobe customer network.

Adobe said the credit card numbers were encrypted and that the company does not believe decrypted credit card numbers left its network. Nevertheless, the company said that later today it will begin the process of notifying affected customers — which include many Revel and Creative Cloud account users —  via email that they need to reset their passwords.

In an interview prior to sending out a news alert on the company’s findings, Adobe’s Chief Security Officer Brad Arkin said the information shared by this publication “helped steer our investigation in a new direction.” Arkin said the company has undertaken a rigorous review of the ColdFusion code shipped since the code archive was compromised, and that it is confident that the source code for ColdFusion code that shipped following the incident “maintained its integrity.”

“We are in the early days of what we expect will be an extremely long and thorough response to this incident,” Arkin said. The company is expected to publish an official statement this afternoon outlining the broad points of its investigation so far.

Arkin said Adobe is still in the process of determining what source code for other products may have been accessed by the attackers, and conceded that Adobe Acrobat may have been among the products the bad guys touched. Indeed, one of the screen shots this publication shared with Adobe indicates that the attackers also had access to Acrobat code, including what appears to be code for as-yet unreleased Acrobat components (see screen grab above).

“We’re still at the brainstorming phase to come up with ways to provide higher level of assurance for the integrity of our products, and that’s going to be a key part of our response,” Arkin said. He noted that the company was in the process of looking for anomalous check-in activity on its code repositories and for other things that might seem out of place.

“We are looking at malware analysis and exploring the different digital assets we have. Right now the investigation is really into the trail of breadcrumbs of where the bad guys touched.”

The revelations come just two days after KrebsOnSecurity published a story indicating that the same attackers apparently responsible for this breach were also involved in the intrusions into the  networks of the National White Collar Crime Center (NW3C), a congressionally-funded non-profit organization that provides training, investigative support and research to agencies and entities involved in the prevention, investigation and prosecution of cybercrime. As noted in that story, the attackers appear to have initiated the intrusion into the NW3C using a set of attack tools that leveraged security vulnerabilities in Adobe’s ColdFusion Web application server.

While Adobe many months ago issued security updates to plug all of the ColdFusion vulnerabilities used by the attackers, many networks apparently run outdated versions of the software, leaving them vulnerable to compromise. This indeed may have also been the vector that attackers used to infiltrate Adobe’s own networks; Arkin said the company has not yet determined whether the servers that were breached were running ColdFusion, but acknowledged that the attackers appear to have gotten their foot in the door through “some type of out-of-date” software.

Stay tuned for further updates on this rapidly-moving story.

Update 4:38 p.m. ET: Adobe has released a statement about these incidents here and here. A separate customer security alert for users affected by this breach is here. Also, in a hopefully unrelated announcement, Adobe says it will be releasing critical security updates next Tuesday for Adobe Acrobat and Adobe Reader.

Update, Oct. 5, 4:35 p.m. ET: Rakshith Naresh, a product manager at Adobe, said in a Tweet yesterday that the breach did not involve ColdFusion vulnerabilities.

Update, Oct. 9, 12:50 p.m. ET: Naresh’s Tweet stating that the breach didn’t involve ColdFusion servers was deleted at some point. I followed up with Adobe via email: An Adobe spokesperson said the company’s investigation is still ongoing, and that “at this time we have not identified the initial attack vector to include or exclude a ColdFusion server.”

Feds Take Down Online Fraud Bazaar ‘Silk Road’, Arrest Alleged Mastermind

October 2, 2013

Defendant Charged With Drug Trafficking, Hacking, Money Laundering

Prosecutors in New York today said that federal agencies have taken over the Silk Road, a sprawling underground Web site that has earned infamy as the “eBay of drugs.” On Tuesday, federal agents in San Francisco arrested the Silk Road’s alleged mastermind. Prosecutors say 29-year-old Ross William Ulbricht, a.k.a “Dread Pirate Roberts” (DPR), will be charged with a range of criminal violations, including conspiracy to commit drug trafficking, and money laundering.

The Silk Road is an online black market that as late as last month was hosting nearly 13,000 sales listings for controlled substances, including marijuana, LSD, heroin, cocaine, methamphetamine and ecstasy. Much like eBay sellers, merchants on the Silk Road are evaluated by previous buyers, who are encouraged to leave feedback about the quality of the seller’s goods and services.

The Silk Road is not available via the regular Internet. Rather, it is only reachable via the Tor network, an anonymity network that bounces its users communications across a distributed network of relays run by volunteers all around the world.

That is, it was until this week, when FBI agents arrested its alleged proprietor and seized the Web servers running the site. The feds also replaced the Silk Road’s home page with a message saying that the site had been seized by the FBI, Homeland Security Department and the Drug Enforcement Administration.

According to a complaint unsealed this week, Ulbricht alone controlled the massive profits generated from the operation of the business. The government alleges that Ulbricht also controlled and oversaw all aspects of the Silk Road, including: the maintenance of the computer infrastructure and programming code underlying the Silk Road Web site; the determination of vendor and customer policies; decisions about what could be sold on the site; and managing a small staff of online administrators who assisted with the day-to-day operations.

The Silk Road didn’t just sell drugs. For example, the complaint identifies 801 for-sale listings under “digital goods,” which included banking Trojans, pirated content, and hacked accounts at Netflix and Amazon. The “forgeries” section of the Silk Road featured 169 ads from vendors of fake driver’s licenses, passports, Social Security cards, utility bills, credit card statements, car insurance records, and other forms of identity documents.

Another popular section of the Silk Road included 159 listings for generic “Services,” mostly those listed by computer hackers offering such services as hijacking Twitter and Facebook accounts of the customer’s choosing. Other classified ads promised the sale of anonymous bank accounts, counterfeit bills, firearms and ammunition, and even hitmen for hire.

FBI investigators said that on or about March 29, 2013, Ulbricht contacted a Silk Road seller “Redandwhite” to see about hiring him to to take out another Silk Road user — someone going by the nickname “FriendlyChemist” — who was threatening to release the identities of thousands of users of the site.

From the government’s complaint: “Asked what sort of problem FriendlyChemist was causing him, DPR responded in a message dated March 30, 2013, ‘[H]e is threatening to expose the identities of thousands of my clients that he was able to acquire….[T]his kind of behavior is unforgivable to me. Especially here on Silk Road, anonymity is sacrosanct.'” As to the murder-for-hire job he was soliciting, DPR commented that “[i]t doesn’t have to be clean.”

Later that same day, redandwhite sent DPR a message quoting him a price of $150,000 to $300,000, “depending on how you want it done, ‘clean’ or ‘non-clean’.

On March 31, DPR began haggling over the price, responding: “Don’t want to be a pain here, but the price seems high. Not long ago, I had a clean hit done for $80k. Are the prices you quoted the best you can do? I would like this done asap as he is talking about releasing the info on Monday.”

According to investigators, the two ultimately settle on a price of $150,000, and that Ulbricht paid for the transaction using Bitcoins — an anonymous virtual currency — sending the would-be hit man 1,670 bitcoins for the arranged hit. Bitcoin currency rates fluctuate quite a bit from day to day, but historic sites that track Bitcoin rates show that one bitcoin around that date in late March 2013 was worth about USD $90, meaning investigators believe Ulbricht paid approximately $150,300 for the hit.

The government’s complaint states that the hit wasn’t carried out, but it also doesn’t seem that FriendlyChemist was the source of investigators’ break in this case. That would come on July 23, 2013, when investigators gained access to a Silk Road server and made a complete copy of the data on the machine.

Nicholas Weaver, a researcher at the International Computer Science Institute (ICSI) and at University of California San Diego, said the information contained on the server seized by investigators indicates that Ulbricht/Dread Pirate Roberts routinely failed to heed his own advice to fellow Silk Road users: Prominent on the Silk Road site were links to tutorials DPR penned which laid out the technologies and techniques that users should adopt if they want to keep off the radar of federal investigators.

“This shows me that the head of the Silk Road wasn’t using [encryption] for all his communications, because [the government] wouldn’t have all of this information otherwise, unless of course he stored his encryption key on the server that was seized,” Weaver said. “Either [the government] got his encryption key off of this server or another server that they were able to access, or he wasn’t using encryption at all.”

The complaint also suggests that in June 2013, Ulbricht accessed a server used to control the Silk Road site from an Internet cafe that was 500 feet from the hotel he was staying at in San Francisco.

Data Broker Hackers Also Compromised NW3C

October 1, 2013

The same miscreants responsible for breaking into the networks of America’s top consumer and business data brokers appear to have also infiltrated and stolen huge amounts of data from the National White Collar Crime Center (NW3C), a congressionally-funded non-profit organization that provides training, investigative support and research to agencies and entities involved in the prevention, investigation and prosecution of cybercrime.

The bot that was resident for  almost 3 months inside of NW3C.

The bot that was resident for almost 3 months inside of NW3C.

Last week, KrebsOnSecurity reported that entrepreneurs behind the underground criminal identity theft service ssndob[dot]ms also were responsible for operating a small but powerful collection of hacked computers exclusively at top data brokers, including LexisNexis, Dun & Bradstreet and HireRight/Kroll. A closer analysis of the Web server used to control that collection of hacked PCs shows that the attackers also had at least one infected system for several months this summer inside of the NW3c.

Core to the NW3C’s mission is its Investigative Support division, which according to the organization’s site “provides timely, relevant and effective services to member agencies involved in the prevention, investigation and prosecution of economic and high-tech crimes. The section has no investigative authority but can provide analytical assistance and perform public database searches.”

The NW3C said its analysts are frequently called upon to assist in establishing financial transaction patterns, developing possible links between criminal targets and associated criminal activity and providing link charts, timelines and graphs for court presentations. “Information obtained through public database searches can assist investigations by locating suspects, establishing property ownership and finding hidden assets, just to name a few of the benefits,” the organization’s Web site explains.

The NW3C also works with the Federal Bureau of Investigation (FBI) to run the Internet Crime Complaint Center (IC3), which accepts online Internet crime complaints from victims of cybercrime.

Neither the NW3C nor the IC3 responded to requests for comment on this story. FBI Spokeswoman Lindsay Godwin would say only that the FBI was “looking into it,” but declined to elaborate further, citing the ongoing nature of the investigation.

THE CRIME MACHINE

A number of indicators suggest that the attackers first gained access to the NW3C’s internal network on or around May 28, 2013. According to records in the online communications panel that the miscreants used to control their network of hacked systems, the affected NW3C server was taken offline on or around Aug. 17, 2013, indicating that the organization’s networks were compromised for approximately 11 weeks this summer. It’s not clear at this point why the miscreants marked this organization’s listing with a “(hacker)” designation, as shown in the snapshot of their botnet control panel below.

nw3cBAP

The attackers appear to have compromised a public-facing server at NW3C that was designed to handle incoming virtual private network (VPN) communications. Organizations frequently set up VPNs so that their remote employees can create an encrypted communications tunnel back to an otherwise closed network, and these setups are an integral component of most modern business applications.

Alarmingly, the machine name of the compromised NW3C system was “data.” On May 28, 2013, the attackers uploaded a file — nbc.exe — designed to open up an encrypted tunnel of communications from the hacked VPN server to their botnet controller on the public Internet. This appears to be the same nbc.exe file that was found on the two hacked servers at LexisNexis.

Abundant evidence left behind by the attackers suggests that they broke into the NW3C using a Web-based attack tool that focuses on exploiting recently-patched weaknesses in servers powered by ColdFusion, a Web application platform owned by Adobe Systems. I managed to get hold of the multiple exploits used in the attack server, and shared them with Adobe and with Rob Brooks-Bilson, a ColdFusion expert and author of the O’Reilly books Programming ColdFusion MX and Programming ColdFusion.

Although some of the exploits were listed as “0day” in the attack tool — suggesting they were zero-day, unpatched vulnerabilities in Adobe ColdFusion — Bilson said all of the exploits appear to attack vulnerabilities that are fixed in the most recent versions of ColdFusion. For example, three of the four exploits seems to have involved CVE-2013-0632, a vulnerability that Adobe first patched in January 2013, not long after the flaw was first spotted in actual zero-day online attacks. The remaining exploit in the attack kit targets a bug that Adobe fixed in 2010.

“The big issue with ColdFusion is that so many people install and set it up without following any of Adobe’s hardening guidelines,” Brooks-Bilson said in an email to KrebsOnSecurity. “Most of the exploits that have come out in the recent past have all worked via a similar mechanism that is easily mitigated by following Adobe’s guide. Of course, so many people disregard that advice and end up with servers that are easily compromised.”

STEALING DATA ON VICTIMS AND FELLOW CROOKS ALIKE

The ColdFusion exploit server contains plenty of records indicating that the attackers in this case plundered many of the databases that they were able to access while inside of NW3C. Part of the reason for the persistence of this evidence has to do with the way that the attackers queried local databases and offloaded stolen data. It appears that once inside the NW3C’s network, the bad guys quickly scanned all of the organization’s systems for security vulnerabilities and database servers. They also uploaded a Web-based “shell” which let them gain remote access to the hacked server via a Web browser.

The attack server and shell also let the attackers execute system commands on the compromised hosts, which appear to be Microsoft IIS servers. Their method also left a detailed (if not complete) log of many of their activities inside the network. One of the first things the attackers did upon compromising the “Data” server on the network was run a query that forced the local database to dump a copy of itself to a file — including a list of the authorized users and passwords —  that the attackers could download.

The bad guys in this case also appear to have used their access to the NW3C to steal 10 years’ worth of consumer complaint information from the Internet Crime Complaint Center (IC3), the aforementioned partnership between the NW3C and the FBI that tracks complaints about cybercrime.

Present on the attacker’s server are some 2.659 million records apparently lifted from the IC3. The records range in date from about the time of the IC3’s inception — May 8, 2000 — to Jan. 22, 2013.

It’s not clear if the stolen IC3 data set includes all of the consumer complaints ever filed, but it seems likely that the archive is lacking just the past few months of records. In a report released earlier this year, the IC3 said it was receiving about 24,000 complaints per month, and that consumers had filed 289,874 complaints last year. The IC3’s site doesn’t maintain annual complaint numbers prior to 2003, but according to the site some 2.35 million have been filed with the system since then. To put the year-over-year growth in complaints in perspective, the IC3 said it wasn’t until 2007 — nearly seven years after its birth — that the organization received its millionth complaint.

Data Broker Giants Hacked by ID Theft Service

September 25, 2013

An identity theft service that sells Social Security numbers, birth records, credit and background reports on millions of Americans has infiltrated computers at some of America’s largest consumer and business data aggregators, according to a seven-month investigation by KrebsOnSecurity.

ssndobhomeThe Web site ssndob[dot]ms (hereafter referred to simply as SSNDOB) has for the past two years marketed itself on underground cybercrime forums as a reliable and affordable service that customers can use to look up SSNs, birthdays and other personal data on any U.S. resident. Prices range from 50 cents to $2.50 per record, and from $5 to $15 for credit and background checks. Customers pay for their subscriptions using largely unregulated and anonymous virtual currencies, such as Bitcoin and WebMoney.

Until very recently, the source of the data sold by SSNDOB has remained a mystery. That mystery began to unravel in March 2013, when teenage hackers allegedly associated with the hacktivist group UGNazi showed just how deeply the service’s access went. The young hackers used SSNDOB to collect data for exposed.su, a Web site that listed the SSNs, birthdays, phone numbers, current and previous addresses for dozens of top celebrities — such as performers Beyonce, Kanye West and Jay Z — as well as prominent public figures, including First Lady Michelle Obama, CIA Director John Brennan, and then-FBI Director Robert Mueller.

Earlier this summer, SSNDOB was compromised by multiple attackers, its own database plundered. A copy of the SSNDOB database was exhaustively reviewed by KrebsOnSecurity.com. The database shows that the site’s 1,300 customers have spent hundreds of thousands of dollars looking up SSNs, birthdays, drivers license records, and obtaining unauthorized credit and background reports on more than four million Americans.

Frustratingly, the SSNDOB database did not list the sources of that stolen information; it merely indicated that the data was being drawn from a number of different places designated only as “DB1,” “DB2,” and so on.

But late last month, an analysis of the networks, network activity and credentials used by SSNDOB administrators indicate that these individuals also were responsible for operating a small but very potent botnet — a collection of hacked computers that are controlled remotely by attackers. This botnet appears to have been in direct communications with internal systems at several large data brokers in the United States.  The botnet’s Web-based interface (portions of which are shown below) indicated that the miscreants behind this ID theft service controlled at least five infected systems at different U.S.-based consumer and business data aggregators.

DATA-BROKER BOTNET

Two of the hacked servers were inside the networks of Atlanta, Ga.-based LexisNexis Inc., a company that according to Wikipedia maintains the world’s largest electronic database for legal and public-records related information. Contacted about the findings, LexisNexis confirmed that the two systems listed in the botnet interface were public-facing LexisNexis Web servers that had been compromised.

One of two bots connected to SSNDOB that was inside of LexisNexis.

The botnet’s online dashboard for the LexisNexis systems shows that a tiny unauthorized program called “nbc.exe” was placed on the servers as far back as April 10, 2013, suggesting the intruders have had access to the company’s internal networks for at least the past five months. The program was designed to open an encrypted channel of communications from within LexisNexis’s internal systems to the botnet controller on the public Internet.

Two other compromised systems were located inside the networks of Dun & Bradstreet, a Short Hills, New Jersey data aggregator that licenses information on businesses and corporations for use in credit decisions, business-to-business marketing and supply chain management. According to the date on the files listed in the botnet administration panel, those machines were compromised at least as far back as March 27, 2013.

The fifth server compromised as part of this botnet was located at Internet addresses assigned to Kroll Background America, Inc., a company that provides employment background, drug and health screening. Kroll Background America is now part of HireRight, a background-checking firm managed by the Falls Church, Va.-based holding company Altegrity, which owns both the Kroll and HireRight properties. Files left behind by intruders into the company’s internal network suggest the HireRight breach extends back to at least June 2013.

An initial analysis of the malicious bot program installed on the hacked servers reveals that it was carefully engineered to avoid detection by antivirus tools. A review of the bot malware in early September using Virustotal.com — which scrutinizes submitted files for signs of malicious behavior by scanning them with antivirus software from nearly four dozen security firms simultaneously — gave it a clean bill of health: none of the 46 top anti-malware tools on the market today detected it as malicious (as of publication, the malware is currently detected by 6 out of 46 anti-malware tools at Virustotal).

Crooks Hijack Retirement Funds Via SSA Portal

September 18, 2013

If you receive direct deposits from the Social Security Administration but haven’t yet registered at the agency’s new online account management portal, now would be a good time take care of that: The SSA and financial institutions say they are tracking a rise in cases wherein identity thieves register an account at the SSA’s portal using a retiree’s personal information and have that retiree’s benefits diverted to prepaid debit cards that the crooks control.

The SSA's "my Social Security" portal.

The SSA’s “my Social Security” portal.

Traditional SSA fraud involves identity thieves tricking the beneficiary’s bank into diverting the payments to another account, either through Social Security’s 800 number or through a financial institution, or through Treasury’s Direct Express program. The newer version of this fraud involves the abuse of the SSA’s my Social Security Web portal, which opened last year and allows individuals to create online accounts with the SSA to check their earnings and otherwise interact with the agency relative to their accounts.

Jonathan Lasher, assistant inspector general for external relations at the SSA’s Office of Inspector General, said that for several years the agency was receiving about 50 such allegations a day, though those numbers have begun to decline. But thieves didn’t go away: They just changed tactics. The trouble really began earlier this year, when the Treasury started requiring that almost all beneficiaries receive payments through direct deposit (though the SSA says paper checks are still available to some beneficiaries under limited circumstances).

At the same time, the SSA added the ability to change direct deposit information via their my Social Security Web portal. Shortly thereafter, the agency began receiving complaints that identity thieves were using the portal to hijack the benefits of individuals who had not yet created an account at the site. According to Lasher, as of August 23, 2013, the SSA has received 18,417 allegations of possibly fraudulent mySocialSecurity account activity. Lasher said while some of the complaints are the result of unsuccessful attempts to open an account fraudulently, some are indeed fraud.

“Social Security has already improved security over this online feature, and we continue to work with them to make additional improvements, while also investigating allegations we receive,” Lasher said. “While it’s an issue we’re taking very seriously, it’s important to keep in mind that about 62 million people receive some type of payment from SSA every month, so the likelihood of becoming a victim is very small, particularly if you’re careful about protecting your personal information.”

Because it’s possible to create just one my Social Security account per Social Security number, registering an account on the portal is one basic way that consumers can avoid becoming victims of this scam. Lasher said in the SSA’s systems, every record is tied to the SSN rather than a person’s name, since there are so many duplicate names.

“Of course, the one way to ensure that no one opens an account in your name is to open one yourself,” Lasher said. “Given the nature of other articles on your site, I think it’s important that I point out that there is no suggestion that SSA’s systems have been compromised; this is an identity theft scheme aimed at redirecting existing benefits, often to prepaid debit cards.”

Microsoft: IE Zero Day Flaw Affects All Versions

September 17, 2013

Microsoft said today that attackers are exploiting a previously unknown, unpatched vulnerability in all supported versions of its Internet Explorer Web browser. The company said it is working on an official patch to plug the security hole, but in the meantime it has released a stopgap fix to help protect affected customers.

IEwarningMicrosoft said it is aware of targeted attacks that attempt to exploit the vulnerability (CVE-2013-3893) in IE 8 and IE 9 versions of the default Windows browser. According to an advisory issued today, the flaw is a remote code bug, which means malware or miscreants could use it install malware just by coaxing IE users to browse a hacked or malicious Web site.

The Fix It solution is available from this link. To apply it, click the Fix It icon above the Fix This Problem link. Applying this solution may limit some functionalities of IE, so if you run into problems after applying this interim patch, you can click the Fix It icon to the right of that “enable” button to reverse the update.

Update: As several readers have already noted in the comments, this Fix It solution is for 32-bit versions of IE only. In 64-bit Windows, you can tell whether the browser you’re using is a 32-bit or 64-bit version by opening the Windows Task Manager (Ctrl+Shift+Esc) and clicking the Processes tab. The number that appears after the process name (in this case, iexplore.exe) indicates the version in use.

WHOIS Privacy Plan Draws Fire

September 16, 2013

Internet regulators are pushing a controversial plan to restrict public access to WHOIS Web site registration records. Proponents of the proposal say it would improve the accuracy of WHOIS data and better protect the privacy of people who register domain names. Critics argue that such a shift would be unworkable and make it more difficult to combat phishers, spammers and scammers.

ardsA working group within The Internet Corporation for Assigned Names and Numbers (ICANN), the organization that oversees the Internet’s domain name system, has proposed scrapping the current WHOIS system — which is inconsistently managed by hundreds of domain registrars and allows anyone to query Web site registration records. To replace the current system, the group proposes creating a more centralized WHOIS lookup system that is closed by default.

According to an interim report (PDF) by the ICANN working group, the WHOIS data would be accessible only to “authenticated requestors that are held accountable for appropriate use” of the information.

“After working through a broad array of use cases, and the myriad of issues they raised, [ICANN’s working group] concluded that today’s WHOIS model—giving every user the same anonymous public access to (too often inaccurate) registration data—should be abandoned,” ICANN’s “expert working group” wrote. The group said it “recognizes the need for accuracy, along with the need to protect the privacy of those registrants who may require heightened protections of their personal information.”

The working group’s current plan envisions creating what it calls an “aggregated registration directory service” (ARDS) to serve as a clearinghouse that contains a non-authoritative copy of all of the collected data elements. The registrars and registries that operate the hundreds of different generic top-level domains (gTLDs, like dot-biz, dot-name, e.g.) would be responsible for maintaining the authoritative sources of WHOIS data for domains in their gTLDs. Those who wish to query WHOIS domain registration data from the system would have to apply for access credentials to the ARDS, which would be responsible for handling data accuracy complaints, auditing access to the system to minimize abuse, and managing the licensing arrangement for access to the WHOIS data.

The plan acknowledges that creating a “one-stop shop” for registration data also might well paint a giant target on the group for hackers, but it holds that such a system would nevertheless allow for greater accountability for validating registration data.

Unsurprisingly, the interim proposal has met with a swell of opposition from some security and technology experts who worry about the plan’s potential for harm to consumers and cybercrime investigators.

“Internet users (individuals, businesses, law enforcement, governments, journalists and others) should not be subject to barriers – including prior authorization, disclosure obligations, payment of fees, etc. – in order to gain access to information about who operates a website, with the exception of legitimate privacy protection services,” reads a letter (PDF) jointly submitted to ICANN last month by G2 Web Services, OpSec Security, LegitScript and DomainTools.

“Internet users have the right to know who is operating a website they are visiting (or, the fact that it is registered anonymously),” the letter continues. “Today, individuals review full WHOIS records and, based on any one of the fields, identify and report fraud and other abusive behaviors; journalists and academics use WHOIS data to conduct research and expose miscreant behavior; and parents use WHOIS data to better understand who they (or their children) are dealing with online. These and other uses improve the security and stability of the Internet and should be encouraged not burdened by barriers of a closed by default system.”

‘Yahoo Boys’ Have 419 Facebook Friends

September 11, 2013

Earlier this week, I wrote about an online data theft service that got hacked. That compromise exposed a user base of mostly young Nigerian men apparently engaged in an array of cybercrime activities — from online dating scams to 419 schemes. It turned out that many of these guys signed up for the data theft service using the same email address they used to register their Facebook accounts. Today’s post looks at the social networks between and among these individuals.

Of the nearly 3,000 BestRecovery users, about 280 of them had Facebook accounts tied to their BestRecovery email addresses. George Mason University associate professor Damon McCoy and several of his grad students volunteered to scrape those profiles that were open and map their social networks to see if there were any obvious or discernible patterns in the data.

The raw data itself — which ranked the BestRecovery users on number of connections they had to other users — was potentially useful, but difficult to parse into meaningful chunks. Oddly enough, as I was poring over that data I heard from Chris Ahlberg, the CEO of Recorded Future Inc., a Cambridge, Mass. software company that specializes in Web intelligence and predictive analytics. Ahlberg was writing to say that he enjoyed the blog — particularly the posts with data-intensive analyses — and that he’d be delighted to collaborate on a data-rich research project at some point. I told him his timing couldn’t have been more serendipitous.

Ahlberg and his team took the raw scraped data sets from the Facebook accounts and ran it through their cyber intelligence applications. In short order, they produced some very compelling and beautiful graphs, shown below.

Staffan Truvé, Recorded Future’s chief technology officer noted that — with few exceptions — the BestRecovery users largely appear to belong to one of two very separate social networks.

RecordedFuture's rendering of the Facebook profiles shows fairly two tight-knit social networks.

RecordedFuture’s rendering of the Facebook profiles shows fairly two tight-knit social networks.

“There appears to be two fairly separate, quite tightly knit networks, each with a few central leaders, and also with just a few individuals being the bridge between the two networks — and that those middlemen are themselves not connected,” said Staffan Truvé, Recorded Future’s chief technology officer.

I noted in my previous story that a majority of the BestRecovery keylog service users who had Facebook pages that reported a location listed either somewhere in Nigeria (usually Lagos), or Kuala Lumpur, Malaysia. Not surprisingly, those two geographic groups are generally represented by these two globs of Facebook users (with several exceptions of users who are from Nigeria but living in Kuala Lumpur and vice versa).

Here’s a closer look at the most influential/connected members at the center of Cluster 1 (upper in the diagram above)

Adobe, Microsoft Push Critical Security Fixes

September 10, 2013

Adobe and Microsoft each separately released a raft of updates to fix critical security holes in their software. Adobe pushed patches to plug holes in Adobe Acrobat/Reader and its Flash and Shockwave media players. Microsoft released 14 13 patch bundles to fix at least 47 security vulnerabilities in Windows, Office, Internet Explorer and Sharepoint.

crackedwinFour of the 13 bulletins Microsoft released today earned the company’s “critical” rating, meaning that on balance they address vulnerabilities that can be exploited by miscreants or malware to break into vulnerable systems without any help from users.

For enterprises and those who need to prioritize the installation of updates, Microsoft recommends installing the Outlook, Internet Explorer and SharePoint Server fixes as soon as possible. The Sharepoint update addresses some ten vulnerabilities, including one that Microsoft says was publicly disclosed prior to today’s patch batch.

Adobe’s Flash update fixes at least four flaws in the widely-installed media player, and brings the player to version 11.8.800.168 for Mac and Windows users (users of other OSes please see the chart below). Google Chrome should auto-update itself to the latest version for Chrome (11.8.800.170 for Windows, Mac and Linux); Google says it is in the process of rolling out the update, although my test version of Chrome is still stuck at v. 11.8.800.97, even after installing updates for Chrome and restarting. Likewise, Internet Explorer 10 should auto-update to the latest version. To find out which version of Flash you have installed, see this page.

The most recent versions of Flash are available from the Adobe download center, but beware potentially unwanted add-ons, like McAfee Security Scan). To avoid this, uncheck the pre-checked box before downloading, or grab your OS-specific Flash download from here. Windows users who browse the Web with anything other than Internet Explorer will need to apply this patch twice, once with IE and again using the alternative browser (FirefoxOpera, e.g.).
