    FBI: Smart Meter Hacks Likely to Spread

    A series of hacks perpetrated against so-called “smart meter” installations over the past several years may have cost a single U.S. electric utility hundreds of millions of dollars annually, the FBI said in a cyber intelligence bulletin obtained by KrebsOnSecurity. The law enforcement agency said this is the first known report of criminals compromising the hi-tech meters, and that it expects this type of fraud to spread across the country as more utilities deploy smart grid technology.

    Part of an FBI alert about smart meter hacks.

    Smart meters are intended to improve efficiency, reliability, and allow the electric utility to charge different rates for electricity at different times of day. Smart grid technology also holds the promise of improving a utility’s ability to remotely read meters to determine electric usage.

    But it appears that some of these meters are smarter than others in their ability to deter hackers and block unauthorized modifications. The FBI warns that insiders and individuals with only a moderate level of computer knowledge are likely able to compromise meters with low-cost tools and software readily available on the Internet.

    Sometime in 2009, an electric utility in Puerto Rico asked the FBI to help it investigate widespread incidents of power thefts that it believed was related to its smart meter deployment. In May 2010, the bureau distributed an intelligence alert about its findings to select industry personnel and law enforcement officials.

    Citing confidential sources, the FBI said it believes former employees of the meter manufacturer and employees of the utility were altering the meters in exchange for cash and training others to do so. “These individuals are charging $300 to $1,000 to reprogram residential meters, and about $3,000 to reprogram commercial meters,” the alert states.

    The FBI believes that miscreants hacked into the smart meters using an optical converter device — such as an infrared light — connected to a laptop that allows the smart meter to communicate with the computer. After making that connection, the thieves changed the settings for recording power consumption using software that can be downloaded from the Internet.

    “The optical converter used in this scheme can be obtained on the Internet for about $400,” the alert reads. “The optical port on each meter is intended to allow technicians to diagnose problems in the field. This method does not require removal, alteration, or disassembly of the meter, and leaves the meter physically intact.”

    The bureau also said another method of attacking the meters involves placing a strong magnet on the devices, which causes it to stop measuring usage, while still providing electricity to the customer.

    “This method is being used by some customers to disable the meter at night when air-conditioning units are operational. The magnets are removed during working hours when the customer is not home, and the meter might be inspected by a technician from the power company.”

    “Each method causes the smart meter to report less than the actual amount of electricity used.  The altered meter typically reduces a customer’s bill by 50 percent to 75 percent.  Because the meter continues to report electricity usage, it appears be operating normally.  Since the meter is read remotely, detection of the  fraud is very difficult.  A spot check of meters conducted by the utility found that approximately 10 percent of meters had been altered.”

    “The FBI assesses with medium confidence that as Smart Grid use continues to spread throughout the country, this type of fraud will also spread because of the ease of intrusion and the economic benefit to both the hacker and the electric customer,” the agency said in its bulletin.

    The feds estimate that the Puerto Rican utility’s losses from the smart meter fraud could reach $400 million annually. The FBI didn’t say which meter technology or utility was affected, but the only power company in Puerto Rico with anywhere near that volume of business is the publicly-owned Puerto Rican Electric Power Authority (PREPA). The company did not respond to requests for comment on this story.

    Global Payments: Rumor and Innuendo

    Global Payments Inc., the Atlanta-based credit and debit card processor that recently announced a breach that exposed fewer than 1.5 million card accounts, held a conference call this morning to discuss the incident. Unfortunately, that call created more questions than it did answers, at least for me. The purpose of this post is to provide some information that I have gathered, and a few observations about the reporting on this breach so far.

    In a conference call this morning, Paul Garcia, Chairman and CEO of Global Payments (NYSE: GPN), declined to offer few new details about how the breach happened, beyond the details the company released in its press release last night. He also declined to comment on reports that the breach may have dated back to at least January 2012. Garcia emphasized that the company self-reported and discovered the intrusion in early March, and proactively notified law enforcement officials and hired independent forensics investigators.

    When asked about the timeline first reported by KrebsOnSecurity.com last Friday — that Visa and MasterCard were warning of a payment processor that had an exposure between Jan 21, 2012 and Feb. 25, 2012 — Garcia said, without elaborating:

    “There’s a lot of rumor and innuendo out there which is not helpful to anyone, and most of it incredibly inaccurate. In terms of other timelines, I just cannot be specific further about that.”

    He went on to state that, “This does not involve our merchants, our sales partners, or their relationships with their customers. Neither merchant systems, or point of sale devices, were involved in any way. This was self-discovered and self-reported.” Databreaches.net has a decent round-up of the call details, as well as other reporting on this breach. A recording of the conference call is available here.

    I’d like to share a few thoughts on my own reporting as it relates to this breach. First, when I published the story early last Friday morning that is widely credited as the first to break the news of a large processor breach, at that time I did not know for sure that Global Payments had been compromised. I’d heard it from one source, but could not get it from a second source. The old-school reporter in me held back those details from my story.

    Several readers have called me irresponsible for quoting anonymous sources stating that the Global Payments breach may have affected more than 10 million cards. This is simply not true. I didn’t even mention Global Payments in my original piece. That information was dug up by reporters at The Wall Street Journal. Indeed, given GPN’s statements thus far, I continue to be nagged by the possibility that my initial reporting may have been related to a separate, as-yet undisclosed breach at another processor. I mentioned this to a reporter at ABC News today, who included my perspective in a story here.

    RUMOR AND INNUENDO

    GPN said it would allow an hour for the call and for questions, but it told callers at the beginning of the conference that it would be using a portion of the call time to talk about its 4th quarter earnings. Although I sat in on the GPN call this morning for the entire hour and waited in the queue to ask questions, I was not afforded the opportunity. Nor did I hear questions allowed from reporters at mainstream news media outlets cited in this story. The company has not yet responded to my questions, which I submitted in a phone call after the news conference.

    What follows is a partial brain dump on some of the information and interesting tidbits I’ve been able to uncover in my reporting today, in no particular order. Some or all of them may turn out to be relevant to the Global Payments breach, to a separate incident, or not at all. Continue reading →

    Global Payments: 1.5MM Cards ‘Exported’

    Visa Drops Support for Breached Processor, Acknowledges Weekend Outage

    Global Payments, the credit and debit card processor that disclosed a breach of its systems late Friday, said in a statement Sunday that the incident involved at least 1.5 million accounts. The news comes hours ahead of a planned conference call with investors, and after Visa said it had pulled its seal of approval for the company.

    CNN Money charts Global Payments's stock dive on Friday.

    In a press release issued 9:30 p.m. ET Sunday, Atlanta based Global Payments Inc. said it believes “the affected portion of its processing system is confined to North America and less than 1,500,000 card numbers may have been exported…Based on the forensic analysis to date, network monitoring and additional security measures, the company believes that this incident is contained. ”

    It remains unclear whether there are additional accounts beyond these 1.5 million that were exposed by the breach; the company’s statement seems to be focusing on the number of cards it can confirm that thieves offloaded from its systems.

    It’s also unclear how Global Payments’ timeline of the incident meshes with that of MasterCard and Visa. In an alert sent to card-issuing banks that was first reported early Friday by KrebsOnSecurity.com, the card associations said the window of vulnerability for the breached processor (at that time unnamed) was between Jan. 21, 2012 and Feb. 25, 2012. The alert also said that full Track 1 and Track 2 data was exposed, meaning thieves could use the stolen information to counterfeit new cards.

    Yet, in a statement Friday, Global Payments said its own security systems identified and self-reported the breach, which it said was detected in early March 2012: “It is reassuring that our security processes detected an intrusion,” the company said. Continue reading →

    MasterCard, VISA Warn of Processor Breach

    VISA and MasterCard are alerting banks across the country about a recent major breach at a U.S.-based credit card processor. Sources in the financial sector are calling the breach “massive,” and say it may involve more than 10 million compromised card numbers.

    Update, 4:32 p.m. ET: Atlanta-based processor Global Payments just confirmed that they discovered a breach in early March 2012. See their full statement and several other updates at the end of this story.

    Original post:

    In separate non-public alerts sent late last week, VISA and MasterCard began warning banks about specific cards that may have been compromised. The card associations stated that the breached credit card processor was compromised between Jan. 21, 2012 and Feb. 25, 2012. The alerts also said that full Track 1 and Track 2 data was taken – meaning that the information could be used to counterfeit new cards.

    Neither VISA nor MasterCard have said which U.S.-based processor was the source of the breach. But affected banks are now starting to analyze transaction data on the compromised cards, in hopes of finding a common point of purchase. Sources at two different major financial institutions said the transactions that most of the cards they analyzed seem to have in common are that they were used in parking garages in and around the New York City area.

    Researchers Clobber Khelios Spam Botnet

    Experts from across the security industry collaborated this week to quarantine more than 110,000 Microsoft Windows PCs that were infected with the Khelios worm, a contagion that forces infected PCs to blast out junk email advertising rogue Internet pharmacies.

    Most botnets are relatively fragile: If security experts or law enforcement agencies seize the Internet servers used to control the zombie network, the crime machine eventually implodes. But Khelios (a.k.a. “Kelihos”) was built to withstand such attacks, employing a peer-to-peer structure not unlike that used by popular music and file-sharing sites to avoid takedown by the entertainment industry.

    Update, 11:07 a.m. ET: Multiple sources are now reporting that within hours of the Khelios.B takedown, Khelios.C was compiled and launched. It appears to be spreading via Facebook.

    Original post: The distributed nature of a P2P botnet allows the botmaster to orchestrate its activities by seeding a few machines in the network with encrypted instructions. Those systems then act as a catalyst, relaying the commands from one infected machine to another in rapid succession.

    P2P botnets can be extremely resilient, but they typically posses a central weakness: They are only as strong as the encryption that scrambles the directives that the botmaster sends to infected machines. In other words,  anyone who manages to decipher the computer language needed to talk to the compromised systems can send them new instructions, such as commands to connect to a control server that is beyond the reach of the miscreant(s) who constructed the botnet.

    That’s precisely the approach that security researchers used to seize control of Khelios. The caper was pulled off by a motley band of security experts from the Honeynet Project, Kaspersky, SecureWorks, and startup security firm CrowdStrike. The group figured out how to crack the encryption used to control systems infected with Khelios, and then sent a handful of machines new instructions to connect to a Web server that the researchers controlled.

    That feat allowed the research team to wrest the botnet from the miscreants who created it, said Adam Meyers, director of intelligence for CrowdStrike. The hijacking of the botnet took only a few minutes, and when it was complete, the team had more than 110,000 PCs reporting to its surrogate control server.

    “Once we injected that information in the P2P node, it was essentially propagating everything else for us,” Meyers said. “By taking advantage of the intricacies of the protocol, we were providing the most up-to-date information that all of hosts were spreading.”

    The group is now working to notify ISPs where the infected hosts reside, in hopes of cleaning up the bot infestations. Meyers said that, for some unknown reason, the largest single geographic grouping of Khelios-infected systems – 25 percent — were located in Poland. U.S.-based ISPs were home to the second largest contingent of Khelios bots. Meyers said about 80 percent of the Khelios-infected systems they sinkholed were running Windows XP, an increasingly insecure operating system that Microsoft released more than a decade ago.

    Microsoft Takes Down Dozens of Zeus, SpyEye Botnets

    Microsoft today announced the execution of a carefully planned takedown of dozens of botnets powered by ZeuS and SpyEye — powerful banking Trojans that have helped thieves steal more than $100 million from small to mid-sized businesses in the United States and abroad.

    Microsoft, U.S. Marshals pay a surprise visit to a Scranton, Pa. hosting facility.

    In a consolidated legal filing, Microsoft received court approval to seize several servers in Scranton, Penn. and Lombard, Ill. used to control dozens of ZeuS and SpyEye botnets. The company also was granted permission to take control of 800 domains that were used by the crime machines.The company published a video showing a portion of the seizures, conducted late last week with the help of U.S. Marshals.

    This is the latest in a string of botnet takedowns executed by Microsoft’s legal team, but it appears to be the first one in which the company invoked the Racketeer Influenced and Corrupt Organizations (RICO) Act.

    “The RICO Act is often associated with cases against organized crime; the same is true in applying the civil section of the law to this case against what we believe is an organization of people behind the Zeus family of botnets,” wrote Richard Boscovich, senior attorney for Microsoft’s Digital Crimes Unit. “By incorporating the use of the RICO Act, we were able to pursue a consolidated civil case against everyone associated with the Zeus criminal operation, even if those involved in the “organization” were not necessarily part of the core enterprise.”

    It’s too soon to say how much of an impact this effort will have, or whether it will last long. Previous takedowns by Microsoft — such as its targeting of the Kelihos botnet last fall — have produced mixed results. There also are indications that this takedown may have impacted legitimate — albeit hacked — sites that crooks were using in their botnet operations. According to data recorded by Abuse.ch, a Swiss security site that tracks ZeuS and SpyEye control servers, some of the domains Microsoft seized appear to belong to legitimate businesses whose sites were compromised and used to host components of the malware infrastructure. Among them is a site in Italy that sells iPhone cases, a Thai social networking forum, and a site in San Diego that teaches dance lessons.

    The effort also shines a spotlight on an elusive group of cyber thieves operating out of Ukraine who have been tagged as the brains behind a great deal of the ebanking losses over the past five years, including the authors of ZeuS (Slavik/Monstr) and SpyEye (Harderman/Gribodemon), both identities that were outed on this blog more than 18 months ago. Over the past few years, KrebsOnSecurity has amassed a virtual treasure trove of data about these and other individuals named in the complaint. Look for a follow-up piece with more details on these actors.

    A breakdown of the court documents related to this case is available at zeuslegalnotice.com.

    Twitter Bots Target Tibetan Protests

    Twitter bots — zombie accounts that auto-follow and send junk tweets hawking questionable wares and services — can be an annoyance to anyone who has even a modest number of followers. But increasingly, Twitter bots are being used as a tool to suppress political dissent, as evidenced by an ongoing flood of meaningless tweets directed at hashtags popular for tracking Tibetan protesters who are taking a stand against Chinese rule.

    It’s not clear how long ago the bogus tweet campaigns began, but Tibetan sympathizers say they recently noticed that several Twitter hashtags related to the conflict — including #tibet and #freetibet — are now so constantly inundated with junk tweets from apparently automated Twitter accounts that the hashtags have ceased to become a useful way to track the conflict.

    The discovery comes amid growing international concern over the practice of self-immolation as a means of protest in Tibet. According to the Associated Press, about 30 Tibetans have set themselves on fire since last year to protest suppression of their Buddhist culture and to call for the return of the Dalai Lama — their spiritual leader who fled during a failed 1959 uprising against Chinese rule.

    I first heard about this trend from reader Erika Rand, who is co-producing a feature-length documentary about Tibet called State of Control. Rand said she noticed the tweet flood and Googled the phenomenon, only to find a story I wrote about a similar technique deployed in Russia to dilute Twitter hashtags being used by citizens protesting last year’s disputed parliamentary elections there.

    “We first discovered these tweets looking at Twitter via the web, then looked at TweetDeck to see how quickly they were coming,” Rand said in an email to KrebsOnSecurity.com late last week. “They no longer appear when searching for Tibet on Twitter via the web, but are still flooding in fast via TweetDeck. This looks like an attempt to suppress news about recent activism surrounding Tibet. We’re not sure how long it’s been going on for. We noticed it last night, and it’s still happening now.” Continue reading →

    Half of All ‘Rogue’ Pharmacies at Two Registrars

    Half of all “rogue” online pharmacies — sites that sell prescription drugs without requiring a prescription — got their Web site names from just two domain name registrars, a study released today found. The findings illustrate the challenges facing Internet policymakers in an industry that is largely self-regulated and rewards companies who market their services as safe havens for shadowy businesses.

    Source: LegitScript

    There are about 450 accredited domain name registrars worldwide, but at least one-third of all active rogue pharmacy sites are registered at Internet.bs, a relatively small registrar that purports to operate out of the Bahamas and aggressively markets itself as an “offshore” registrar. That’s according to LegitScript, a verification and monitoring service for online pharmacies.

    LegitScript President John Horton said the company began to suspect that Internet.bs was courting the rogue pharmacy business when it became clear that the registrar has only two-tenths of one percent of the market share for new Web site name registrations. In a report (PDF) being released today, LegitScript said that a separate analysis of more than 9,000 “not recommended” pharmacies compiled by the National Association of Boards of Pharmacy suggested that Internet.bs is sponsoring nearly 44 percent of the Internet’s dodgy pill shops.

    Asked whether he was concerned about allegations that his firm was targeting an industry that seeks out registrars who turn a blind eye to questionable businesses, Internet.bs President Marco Rinaudo replied that, on the contrary, LegitScript’s report was bound to be “excellent advertising for our company.”

    Reached via phone at his home in Panama, Rinaudo said he was under no obligation to police whether his customers’ business may be in violation of some other nation’s laws, absent clear and convincing evidence that his registrants were operating illegally from their own country.

    “Even though I understand they could bother some pharmacy lobby, if an industry likes us, what’s the problem with an online pharmacy, as long as they are operating legally from their own country?” Rinaudo asked. “We cannot accept pressure to shut down a legitimate business just because it is not pleasing to some political lobbying group. We and I personally make sure that all the domains that are in breach of an applicable law and for which we receive a complete report, will be acted on the same day.”

    Banking on Badb in the Underweb

    Underground Web sites can be a useful barometer for the daily volume of criminal trade in goods like stolen credit card numbers and hijacked PayPal or eBay accounts. And if the current low prices at one of Underweb’s newer and more brazen card shops are indicative of a trend, the market for these commodities has never been more cutthroat.

    Visa, Amex cards for sale at Badb.su

    Badb.su is distinguishable from dozens of underground carding shops chiefly by its slick interface and tiny domain name, which borrows on the pseudonym and notoriety of the Underweb’s most recognizable carder. It’s difficult to say whether “Badb” himself would have endorsed the use of his brand for this particular venture, but it seems unlikely: The man alleged by U.S. authorities to be Badb — 29-year-old Vladislav Anatolievich Horohorin — has been in a French prison since his arrest there in 2010. Authorities believe Horohorin is one of the founding members of CarderPlanet, a site that helped move millions of stolen accounts. He remains jailed in France, fighting extradition to the United States (more about his case in an upcoming story).

    Badb.su’s price list shows that purloined American Express and Discover accounts issued to Americans cost between $2.50 and $3 apiece, with MasterCard and Visa accounts commanding slightly lower prices ($2-$3). Cards of any type issued by banks in the United Kingdom or European Union fetch between $4-$7 each, while accounts from Canadian financial institutions cost between $3 to $5 a pop.

    The site also sells verified PayPal and eBay accounts. Verified PayPal accounts with credit cards and bank accounts attached to them go for between 2-3$, while the same combination + access to the account holder’s email inbox increases the price by $2. PayPal accounts that are associated with bank and/or credit accounts and include a balance are sold for between 2 and 10 percent of the available balance. That rate is considerably lower than the last PayPal underground shop I reviewed, which charged 8 to 12 percent of the total compromised account balance.

    Verified PayPal accounts with positive balances sell for between 2-10% of the available balance.

    Ebay auction accounts are priced according to the number of positive “feedback” points that each victim account possesses (feedback is the core of eBay’s reputation system, whereby members evaluate their buying and selling experiences with other members). eBay accounts with fewer than 75 feedback history sell for $2 each, while those with higher levels of feedback command prices of $5 and higher apiece, because these accounts are more likely to be perceived as trustworthy by other eBay members.

    But don’t count on paying for any of these goods with a credit card; Badb.su accepts payment only through virtual currencies such as Liberty Reserve and WebMoney.

    Badb.su, like many other card shops, offers an a-la-carte, card-checking service that allows buyers to gauge the validity of stolen cards before or after purchasing them. Typically, these services will test stolen card numbers using a hijacked merchant account that initiates tiny charges or so-called pre-authorization checks against the card; if the charge or pre-auth clears, the card-checking service issues a “valid” response for the checked card number.

    Feds Request DNSChanger Deadline Extension

    Extradition of Accused Masterminds Moves Forward

    Millions of computers infected with the stealthy and tenacious DNSChanger Trojan may be spared a planned disconnection from the Internet early next month if a New York court approves a new request by the U.S. government. Meanwhile, six men accused of managing and profiting from the huge collection of hacked PCs are expected to soon be extradited from their native Estonia to face charges in the United States.

    DNSChanger modifies settings on a host PC that tell the computer how to find Web sites on the Internet, hijacking victims’ search results and preventing them from visiting security sites that might help detect and scrub the infections. The Internet servers that were used to control infected PCs were located in the United States, and in coordination with the arrest of the Estonian men in November, a New York district court ordered a private U.S. company to assume control over those servers. The government argued that the arrangement would give ISPs and companies time to identify and scrub infected PCs, systems that would otherwise be disconnected from the Internet if the control servers were shut down. The court agreed, and ordered that the surrogate control servers remain in operation until March 8.

    But earlier this month, security firm Internet Identity revealed that the cleanup process was taking a lot longer than expected: The company said more than 3 million systems worldwide — 500,000 in the United States — remain infected with the Trojan, and that at least one instance of the Trojan was still running on computers at 50 percent of Fortune 500 firms and half of all U.S. government agencies. That means that if the current deadline holds, millions of PCs are likely to be cut off from the Web on March 8.

    In a Feb. 17 filing with the U.S. District Court for the Southern District of New York, officials with the U.S. Justice Department, the U.S. Attorney for the Southern District of New York, and NASA asked the court to extend the March 8 deadline by more than four months to give ISPs, private companies and the government more time to clean up the mess. The government requested that the surrogate servers be allowed to stay in operation until July 9, 2012. The court has yet to rule on the request, a copy of which is available here (PDF).

    Not everyone thinks extending the deadline is the best way to resolve the situation. In fact, security-minded folks seem dead-set against the idea. KrebOnSecurity conducted an unscientific poll earlier this month, asking readers whether they thought the government should give affected users more time to clean up infections from the malware, which can be unusually difficult to remove. Nearly 1,400 readers responded that forcing people to meet the current deadline was the best approach. The overwhelming opinion (~9:1) was against extending the March 8 deadline.

    KrebsOnSecurity readers voted almost 9-1 against the idea of extending the Mar. 8 deadline.

    In related news, the six Estonian men arrested and accused of building and profiting from the DNSChanger botnet are expected to be extradited to face computer intrusion and conspiracy charges in the United States.  Continue reading →
