Cybersecurity Information (Over)Sharing Act?

October 27, 2015

The U.S. Senate is preparing to vote on cybersecurity legislation that proponents say is sorely needed to better help companies and the government share information about the latest Internet threats. Critics of the bill and its many proposed amendments charge that it will do little, if anything, to address the very real problem of flawed cybersecurity while creating conditions that are ripe for privacy abuses. What follows is a breakdown of the arguments on both sides, and a personal analysis that seeks to add some important context to the debate.

Up for consideration by the full Senate this week is the Cybersecurity Information Sharing Act (CISA), a bill designed to shield companies from private lawsuits and antitrust laws if they seek help or cooperate with one another to fight cybercrime. The Wall Street Journal and The Washington Post each recently published editorials in support of the bill.

Update, 6:57 p.m. ET: The Senate this afternoon passed CISA by a vote of 74-21.

Original story:

“The idea behind the legislation is simple: Let private businesses share information with each other, and with the government, to better fight an escalating and constantly evolving cyber threat,” the WSJ said in an editorial published today (paywall). “This shared data might be the footprint of hackers that the government has seen but private companies haven’t. Or it might include more advanced technology that private companies have developed as a defense.”

“Since hackers can strike fast, real-time cooperation is essential,” the WSJ continued. “A crucial provision would shield companies from private lawsuits and antitrust laws if they seek help or cooperate with one another. Democrats had long resisted this legal safe harbor at the behest of plaintiffs lawyers who view corporate victims of cyber attack as another source of plunder.”

The Post’s editorial dismisses “alarmist claims [that] have been made by privacy advocates who describe it as a ‘surveillance’ bill”:

“The notion that there is a binary choice between privacy and security is false. We need both privacy protection and cybersecurity, and the Senate legislation is one step toward breaking the logjam on security,” the Post concluded. “Sponsors have added privacy protections that would scrub out personal information before it is shared. They have made the legislation voluntary, so if companies are really concerned, they can stay away. A broad coalition of business groups, including the U.S. Chamber of Commerce, has backed the legislation, saying that cybertheft and disruption are “advancing in scope and complexity.”

But critics of CISA say the devil is in the details, or rather in the raft of amendments that may be added to the bill before it’s passed. The Center for Democracy & Technology (CDT), a nonprofit technology policy group based in Washington, D.C., has published a comprehensive breakdown of the proposed amendments and their potential impacts.

CDT says despite some changes made to assuage privacy concerns, neither CISA as written nor any of its many proposed amendments address the fundamental weaknesses of the legislation. According to CDT, “the bill requires that any Internet user information volunteered by a company to the Department of Homeland Security for cybersecurity purposes be shared immediately with the National Security Agency (NSA), other elements of the Intelligence Community, with the FBI/DOJ, and many other Federal agencies – a requirement that will discourage company participation in the voluntary information sharing scheme envisioned in the bill.”

CDT warns that CISA risks turning the cybersecurity program it creates into a backdoor wiretap by authorizing sharing and use of CTIs (cyber threat indicators) for a broad array of law enforcement purposes that have nothing to do with cybersecurity. Moreover, CDT says, CISA will likely introduce unintended consequences:

“It trumps all law in authorizing companies to share user Internet communications and data that qualify as ‘cyber threat indicators,’ [and] does nothing to address conduct of the NSA that actually undermines cybersecurity, including the stockpiling of zero day vulnerabilities.”

ANALYSIS

On the surface, efforts to increase information sharing about the latest cyber threats seem like a no-brainer. We read constantly about breaches at major corporations in which the attackers were found to have been inside of the victim’s network for months or years on end before the organization discovered that it was breached (or, more likely, they were notified by law enforcement officials or third-party security firms).

If only there were an easier way, we are told, for companies to share so-called “indicators of compromise” — Internet addresses or malicious software samples known to be favored by specific cybercriminal groups, for example — such breaches and the resulting leakage of consumer data and corporate secrets could be detected and stanched far more quickly.

In practice, however, there are already plenty of efforts — some public, some subscription-based — to collect and disseminate this threat data. From where I sit, the biggest impediment to detecting and responding to breaches in a more timely manner comes from a fundamental lack of appreciation — from an organization’s leadership on down — for how much is riding on all the technology that drives virtually every aspect of the modern business enterprise today. While many business leaders fail to appreciate the value and criticality of all their IT assets, I guarantee you today’s cybercrooks know all too well how much these assets are worth. And this yawning gap in awareness and understanding is evident by the sheer number of breaches announced each week. Continue reading

TalkTalk Hackers Demanded £80K in Bitcoin

October 24, 2015

TalkTalk, a British phone and broadband provider with more than four million customers, disclosed Friday that intruders had hacked its Web site and may have stolen personal and financial data. Sources close to the investigation say the company has received a ransom demand of approximately £80,000 (~USD $122,000), with the attackers threatening to publish the TalkTalk’s customer data unless they are paid the amount in Bitcoin.

Screen Shot 2015-10-24 at 10.08.01 AMIn a statement on its Web site, TalkTalk said a criminal investigation was launched by the Metropolitan Police Cyber Crime Unit following “a significant and sustained cyberattack on our website.”

“That investigation is ongoing, but  unfortunately there is a chance that some of the following data has been compromised: names, addresses, date of birth, phone numbers, email addresses, TalkTalk account information, credit card details and/or bank details,” the statement continues. “We are continuing to work with leading cyber crime specialists and the Metropolitan Police to establish exactly what happened and the extent of any information accessed.”

A source close to the investigation who spoke on condition of anonymity told KrebsOnSecurity that the hacker group who demanded the £80,000 ransom provided TalkTalk with copies of the tables from its user database as evidence of the breach. The database in question, the source said, appears related to at least 400,000 people who have recently undergone credit checks for new service with the company. However, TalkTalk’s statement says it’s too early to say exactly how many customers were impacted. “Identifying the extent of information accessed is part of the investigation that’s underway,” the company said.

It appears that multiple hacker collectives have since claimed responsibility for the hack, including one that the BBC described as a “Russian Islamist group” — although sources say there is absolutely no evidence to support that claim at this time.

Separately, promises to post the stolen data have appeared on AlphaBay, a Deep Web black market that specialized in selling stolen goods and illicit drugs. The posting was made by someone using the nickname “Courvoisier.” This member, whose signature describes him as “Level 6 Fraud and Drugs seller,” appears to be an active participant in the AlphaBay market with many vouches from happy customers who’ve turned to him for illegal drugs and stolen credit cards, among other goods and services.

It seems likely that Courvoisier is not bluffing, at least about posting some subset of TalkTalk customer data. According to a discussion thread on Reddit.com dedicated to explaining AlphaBay’s new Levels system, an AlphaBay seller who has reached the status of Level 6 has successfully consummated at least 500 sales worth a total of at least $75,000, and achieved a 90% positive feedback rating or better from previous customers.

IBM Runs World’s Worst Spam-Hosting ISP?

October 21, 2015

This author has long sought to shame Web hosting and Internet service providers who fail to take the necessary steps to keep spammers, scammers and other online ne’er-do-wells off their networks. Typically, the companies on the receiving end of this criticism are little-known Internet firms. But according to anti-spam activists, the title of the Internet’s most spam-friendly provider recently has passed to networks managed by IBM — one of the more recognizable and trusted names in technology and security.

In March 2010, not long after I began working on my new book Spam Nation: The Inside Story of Organized Cybercrime, From Global Epidemic to Your Front DoorI ran a piece titled Naming and Shaming Bad ISPs. That story drew on data from 10 different groups that track spam and malware activity by ISP. At the time, a cloud computing firm called Softlayer was listed prominently in six out of 10 of those rankings.

In June 2013, Softlayer was acquired by IBM. (Update: Oct. 31, 11:43 p.m. ET: As reader Alex and others have pointed out, another ISP listed prominently in this chart below — ThePlanet — is now also part of IBM/Softlayer).

The top spam-friendly ISPs and hosting providers in early 2010. Softlayer and ThePlanet both listed prominently in the top 10, and both are now owned by IBM/Softlayer.

Original story:

Softlayer gradually cleaned up its act, and began responding more quickly to abuse reports filed by anti-spammers and security researchers. In July 2013, the company was acquired by IBM. More recently, however, the trouble at networks managed by Softlayer has returned. Last month, anti-spam group Spamhaus.org listed Softlayer as the “#1 spam hosting ISP,” putting Softlayer at the very top of its World’s Worst Spam Support ISPs index. Spamhaus said the number of abuse issues at the ISP has “rapidly reached rarely previously seen numbers.”

Contacted by KrebsOnSecurity, Softlayer for several weeks did not respond to requests for comment. After reaching out to IBM earlier this week, I received the following statement from Softlayer Communications Director Andre Fuochi:

“With the growth of Softlayer’s global footprint, as expected with any fast growing service, spammers have targeted our platform. We are aggressively working with authorities, groups like The Spamhaus Project, and IBM Security analysts to shut down this recent, isolated spike. Just in the past month we’ve shut down 95 percent of the spam accounts identified by Spamhaus, and continue to actively eliminate this activity.” Continue reading

Flash, Java Patches Fix Critical Holes

October 20, 2015

Adobe has issued a patch to fix a zero-day vulnerability in its Flash Player software. Separately, Oracle today released an update to plug more than two-dozen flaws in its Java software. Both programs plug directly into the browser and are highly targeted by malicious software and malefactors. Although Flash and Java are both widely installed, most users could probably ditch each program with little to no inconvenience or regret. Continue reading

Don’t Be Fooled by Fake Online Reviews Part II

October 19, 2015

In July I wrote about the dangers of blindly trusting online reviews, especially for high-dollar services like moving companies. That piece told the story of Full Service Van Lines, a moving company that had mostly five-star reviews online but whose owners and operators had a long and very public history of losing or destroying their customers’ stuff and generally taking months to actually ship what few damaged goods it delivered. Last week, federal regulators shut the company down.

updownthunbsNBC Miami reports that Full Service Van Lines (FSVL) was shut down by the U.S. Department of Transportation, but not because of consumer complaints. The DOT reportedly revoked the company’s license due to a pattern of safety violations. And that’s saying something: The NBC story said FSVL received more complaints this year than any other Florida mover of its size.

My July story on FSVL concluded that the company’s owners likely inflated and manipulated their online reputation via a search engine optimization (SEO) firm they owned. Unfortunately, this practice is incredibly common among labor-intensive services that do not require the customer to come into the company’s offices but instead come to the consumer. These services include but are not limited to locksmiths, windshield replacement services, garage door repair and replacement technicians, carpet cleaning and other services that consumers very often call for immediate service.

Bryan Seely, a security expert who’s working on an as-yet unpublished book on these so-called dark/black SEO practices, said such services are rife for SEO experts who create hundreds or thousands of phantom companies online with different business names, addresses and phone numbers. The calls to each of these phony firms are eventually all routed back to the SEO company, which sells the customer lead to one of several companies that have agreed in advance to buy such business leads.

As a result, many consumers think they are dealing with one company when they call, yet end up being serviced by a completely unrelated firm that may not have to worry about maintaining a reputation for quality and fair customer service. Continue reading

Adobe, Microsoft Push Critical Security Fixes

October 14, 2015

Adobe and Microsoft on Tuesday each released security updates to remedy critical vulnerabilities in their software. Adobe pushed patches to plug at least 56 security holes present in Adobe Reader and Acrobat, as well as a fix for Flash Player that corrects 13 flaws. Separately, Microsoft issued six update bundles to address at least 33 security problems in various versions of Windows, Microsoft Office and other software.

Three of the patches Microsoft issued earned the company’s most dire “critical” rating, meaning they could be exploited by hackers or malware to take complete control over vulnerable systems without any help from users. According to security firm Shavlik, four of the flaws involve vulnerabilities that were publicly disclosed by someone other than Microsoft prior to this week. The implication here is that malware writers may have had a head start figuring out ways to exploit several of these flaws, so it’s probably best not to let too much grass grow under your feet before applying this month’s updates.

Hacker Who Sent Me Heroin Faces Charges in U.S.

October 13, 2015

A Ukrainian hacker who once hatched a plot to have heroin sent to my Virginia home and then alert police when the drugs arrived had his first appearance in a U.S. court today, after being extradited to the United States to face multiple cybercrime charges.

Sergey Vovnenko, a.k.a. “Fly,” “Flycracker” and “MUXACC1” (muxa is transliterated Russian for “муха” which means “fly”), was set to appear in a Newark courtroom today on charges of stealing and selling credit card and banking data, emptying bank accounts, and running a botnet of more than 12,000 hacked computers and servers, among other alleged crimes.

Fly replies to my direct messages telling him I know his real name and where he lives.

Fly replies to my direct messages telling him I know his real name and where he lives.

I first became acquainted with Fly in 2013, when his Twitter persona (warning: images here may not be safe for work) began sending me taunting tweets laced with epithets and occasional attempts to get me to click dodgy-looking Web links. Fly also took to his Livejournal blog to post copies of my credit report, directions to my home and pictures of my front door.

After consulting with cybercrime researchers at Russian security firm Group-IB, I learned that Fly was the administrator of a closely-guarded but now-defunct cybercrime forum dedicated to financial fraud called thecc[dot]bz (“cc” is a reference to credit cards).

Not long after that, I secretly gained access to his forum. And none too soon: In one lengthy discussion thread on the forum, I found that Fly had solicited donations from fellow fraudsters on the forum to donate Bitcoin currency for a slush fund Fly created for the express purpose of purchasing heroin off of the Silk Road — which was at the time the leading source of illicit drugs on the Dark Web.

Fly’s plan was simple: Have the drugs delivered to my home in my name, and then spoof a call from one of my neighbors to the local police informing them that I was a druggie, that I had druggie friends coming in and out of my house all day long, and that I was even having drugs delivered to my home.

The forum members took care to find the most reputable sellers of heroin on the Silk Road. After purchasing a gram of the stuff from the Silk Road’s top smack seller — a drug dealer who used the nickname “Maestro” — Fly posted the USPS tracking link for the package into the discussion thread on his forum.

At that point, I called the local police and had a cop come out to take an official police report. The officer asked me to contact him again if the drugs actually arrived. Three days later, our local Postal Service carrier hand delivered a thin USPS Express Mail envelope that was postmarked from Chicago. Inside was another blank envelope containing a May 2013 copy of Chicago Confidential, a weekly glossy magazine from the Chicago Tribune.

On the back of the magazine, taped to a full-page ad for jewelry from LesterLampert, were a baker’s dozen individually wrapped packets emblazoned with the same black and gold skull motif that was on Maestro’s Silk Road ad. I immediately contacted the police, who came and dutifully retrieved the drugs, which turned out to be almost pure heroin.

12 packets of what appears to be heroin arrived at my home via the Silk Road on July 29, 2013.

I wrote about the experience of foiling Fly’s plan in a story titled Mail From the (Velvet) Cybercrime Underground. This did not sit well with Fly, who was made to look bad in front of his forum members who’d contributed roughly two Bitcoins to the scheme.

Angry that I’d foiled his plan to have me arrested for drug possession, Fly had a local florist send a gaudy floral arrangement in the shape of a giant cross to my home, complete with a menacing message that addressed my wife and was signed, “Velvet Crabs.”

After this incident, I became intensely curious about the identity of this Fly individual, so I began looking through databases of hacked carding and cybercrime forums. My first real break came when Group-IB provided a key piece of the puzzle: Group-IB researchers found that on the now-defunct vulnes[dot]com, Fly maintained an account under the nickname Flycracker, and signed up with the email address mazafaka@libero.it(.it is the country code for Italy).

According to a trusted source in the security community, that email account was somehow compromised in 2013. The source said the account was full of emailed reports from a keylogging device that was tied to another email address — 777flyck777@gmail.com (according to Google, mazafaka@libero.it is the recovery email address for 777flyck777@gmail.com).

Those keylog reports contained some valuable information, and indicated that Fly had planted a keylogger on his then-fiancee Irina’s computer. On several occasions, those emails show Fly’s wife typed in her Gmail address, which included her real first and last name — Irina Gumenyuk. Continue reading

Arrest of Chinese Hackers Not a First for U.S.

October 13, 2015

The Washington Post reported last week that the Chinese government has quietly arrested a handful of hackers at the urging of the U.S. government, a move described as “an unprecedented step to defuse tensions with Washington at a time when the Obama administration has threatened economic sanctions.” While this a welcome and encouraging development, it is not the first time Beijing has arrested Chinese hackers in response to pressure from the U.S. government.

The action reported by The Post and other media outlets came shortly before Chinese President Xi Jinping’s state visit to Washington late last month. The hackers arrested had reportedly been identified by U.S. officials as having stolen commercial secrets from U.S. firms to be sold or passed along to Chinese state-run companies.

Although The Post has described this action as unprecedented, U.S. government cybercrime investigators have had success convincing Chinese authorities to take such actions in at least one other case previously.

In a report (PDF) presented to Congress on Feb. 29, 2012, the Office of Inspector General for the National Aeronautics and Space Administration (NASA) noted that a lengthy investigation into the cyber theft of sensitive technical data from its systems culminated in the arrest of a Chinese national in China.

“As a result of an OIG investigation and lengthy international coordination efforts, a
Chinese national was detained in December 2010 by Chinese authorities for violations of
Chinese Administrative Law,” NASA Inspector General Paul K. Martin told a House oversight committee. “This case resulted in the first confirmed detention of a Chinese national for hacking activity targeting U.S. Government agencies. Seven NASA systems, many containing export-restricted technical data, were compromised by the Chinese national.” Continue reading

Credit Card Breach at America’s Thrift Stores

October 12, 2015

Another charity store chain has been hacked: America’s Thrift Stores, an organization that operates donations-based thrift stores throughout the southeast United States, said this week that it recently learned it was the victim of a malware-driven security breach that targeted software used by a third-party service provider.

americasthrift“This breach allowed criminals from Eastern Europe unauthorized access to some payment card numbers,” the company’s CEO said in a statement. “This virus/malware, is one of several infecting retailers across North America.”

The statement continues:

“The U.S. Secret Service tells us that only card numbers and expiration dates were stolen. They do not believe any customer names, phone numbers, addresses or email addresses were compromised. This breach may have affected sales transactions between September 1, 2015 and September 27, 2015. If you used your credit or debit card during this time to purchase an item at any America’s Thrift Store location, the payment card number information on your card may have been compromised.”

Nevertheless, several banking sources say they have seen a pattern of fraud on cards all used at America’s Thrift Stores locations indicating that thieves have been able to use the data stolen from the compromised point-of-sale devices to counterfeit new cards.

Founded in 1984, America’s Thrift Stores is a for-profit thrift store and operates in the southeastern United States. The company is headquartered in Birmingham, Alabama and operates stores in Alabama, Georgia, Tennessee, Mississippi and Louisiana. According to the company’s site, the organization employs over 1,000 employees and pays over $4 million to its non- profit partners annually, as it turns donated items into revenue for their missions.

The breach involving America’s Thrift Stores comes on the heels of a similar incident at Goodwill last year. That incident was tied back to security weaknesses at third-party payment vendor C&K Systems, although there is no indication yet which third-party service provider may be at fault in the America’s Thrift Stores breach.

At Experian, Security Attrition Amid Acquisitions

October 8, 2015

T-Mobile disclosed last week that some 15 million customers had their Social Security numbers and other personal data stolen thanks to a breach at Experian, the largest of the big American consumer credit bureaus. But this actually wasn’t the first time that a hacking incident at Experian exposed sensitive T-Mobile customer data, and that previous breach may hold important clues about what went wrong more recently.

On Dec. 30, 2013, T-Mobile said it notified a “relatively small” number of customers that unauthorized access to a file stored on servers owned by Experian had exposed Social Security numbers and driver’s license numbers. The mobile provider identified the breached vendor as Decisioning Solutions, an identity-proofing and authentication company that was acquired by Experian in April 2013. We’ll revisit this acquisition in a few moments.

Over the past week, KrebsOnSecurity has interviewed a half-dozen security experts who said they recently left Experian to find more rewarding and less frustrating work at other corporations. Nearly all described Experian as a company fixated on acquiring companies in the data broker and analytics technology space, even as it has stymied efforts to improve security and accountability at the Costa Mesa, Calif. based firm.

Jasun Tate worked for a year until April 2014 as a chief information security officer delegate and risk consultant at Experian’s government services and e-marketing business units. Tate said he and several of his colleagues left last year after repeatedly running into problems getting buy-in or follow-up support for major projects to beef up security around Experian’s growing stable of companies handling sensitive consumer and government data.

“What the board of directors at Experian wanted security-wise and the security capabilities on the ground were two completely different things,” Tate said. “Senior leadership there said they were pursuing a very aggressive growth-by-acquisition campaign. The acquisition team would have a very strict protocol on how they assess whether a business may be viable to buy, but the subsequent integration of the business into our core security architecture was just a black box of magic in terms of how it was to be implemented. And I’m not saying successful magic at all.”

Another recent former security employee at Experian who agreed to talk on condition of anonymity said it was clear that the company’s board was not well-informed about the true state of security within the company’s various business units.

“When I was there, the board was very big on security and wanting to invest in it and make sure we were doing what we needed to do in order to avoid situations just like this,” the source said. “In my opinion, there’s no way the board was told the whole story, because if they had been then things wouldn’t be where they are are now. We wouldn’t be talking about this. Some things had to have been hidden or spun in a way to look positive somehow.”

BLACK BOX MAGIC

Not long after it acquired the above-mentioned Decisioning Solutions in April 2013, Experian folded the company into its Decision Analytics platform — a unit which provides credit and noncredit data, customer analytics and fraud detection to lenders, cable and satellite companies, telecommunications firms, third-party debt collectors, utilities and to state and federal government entities.

Within hours of the latest T-Mobile breach news hitting the wires, KrebsOnSecurity was contacted by an anonymous source who sent this author a Web link that, when clicked, opened up a support ticket within that Decision Analytics platform in the United Kingdom — with absolutely no authentication needed. That support ticket I viewed appears to have been filed by someone in an office cube at Experian’s data center in Costa Rica who was requesting hardware support for a component of the company’s Global Technology Services division.

Countless internal support requests for access to Experian's Decision Analytics credit information platform were exposed to the Internet without authentication until earlier this week.

Countless internal support requests for access to Experian’s Decision Analytics credit information platform were exposed to the Internet without authentication until earlier this week.

That particular support ticket was relatively uninteresting, but according to my source anyone could view countless other support tickets filed via the support portal for Experian’s Decision Analytics platform.

The same source demonstrated how modifying just one or two numbers at the tail end of that link revealed requests for access to networked file shares from across a range of Experian’s business units. The requests included specific names of network shares, usernames, userIDs, and LanIDs, as well as email addresses, phone numbers of Experian personnel requesting and approving the changes.

The support site also apparently allowed anyone to file support tickets, potentially making it easy for clever attackers who’d studied the exposed support tickets to fabricate a request for access to Experian resources or accounts on the system.

In addition, experts I spoke with who examined the portal said the support site allowed anyone to upload arbitrary file attachments of virtually any file type. Those experts said such file upload capabilities are notoriously easy for attackers to use to inject malicious files into databases and other computing environments, and that having such capability out in the open without at least first requiring users to supply valid username and password credentials is asking for trouble.

KrebsOnSecurity sought comment from Experian to find out if it knew that its Decision Analytics support portal allowed anyone to view the tickets within. The company said in a statement that it had disabled the portal in response to what appeared to be unauthorized access to it and had notified law enforcement.

“We take any unauthorized access to our systems very seriously, and when we detected the unauthorized activities, we shut down the website and notified law enforcement,” the company said in a statement. “Our credit database and core infrastructure were not impacted – nor could they be accessed through this website.  This site was a legacy version of a service to enable clients and internal users to create and log tickets for issues they may have and we had already deployed its replacement solution.” Continue reading
