  • How a Citadel Trojan Developer Got Busted

    Krebs on Security
    A U.S. District Court judge in Atlanta last week handed a five year prison sentence to Mark Vartanyan, a Russian hacker who helped develop and sell the once infamous and widespread Citadel banking trojan. This fact has been reported by countless media outlets, but far less well known is the fascinating backstory about how Vartanyan got caught.
  • Exclusive: Dutch Cops on AlphaBay ‘Refugees’

    Krebs on Security
    Following today's breaking news about U.S. and international authorities taking down the competing Dark Web drug bazaars AlphaBay and Hansa Market, KrebsOnSecurity caught up with the Dutch investigators who took over Hansa on June 20, 2017. When U.S. authorities shuttered AlphaBay on July 5, police in The Netherlands saw a massive influx of AlphaBay refugees who were unwittingly fleeing directly into the arms of investigators. What follows are snippets from an exclusive interview with Petra Haandrikman, team leader of the Dutch police unit that infiltrated Hansa.

    Vendors on both AlphaBay and Hansa sold a range of black market items -- most especially controlled substances like heroin. According to the U.S. Justice Department, AlphaBay alone had some 40,000 vendors who marketed a quarter-million sales listings for illegal drugs to more than 200,000 customers. The DOJ said that as of earlier this year, AlphaBay had 238 vendors selling heroin. Another 122 vendors advertised Fentanyl, an extremely potent synthetic opioid that has been linked to countless overdoses and deaths.

    In our interview, Haandrikman detailed the dual challenges of simultaneously dealing with the exodus of AlphaBay users to Hansa and keeping tabs on the giant increase in new illicit drug orders that were coming in daily as a result.
  • After AlphaBay’s Demise, Customers Flocked to Dark Market Run by Dutch Police

    Krebs on Security
    Earlier this month, news broke that authorities had seized the Dark Web marketplace AlphaBay, an online black market that peddled everything from heroin to stolen identity and credit card data. But it wasn't until today, when the U.S. Justice Department held a press conference to detail the AlphaBay takedown that the other shoe dropped: Police in The Netherlands for the past month have been operating Hansa Market, a competing Dark Web bazaar that enjoyed a massive influx of new customers immediately after the AlphaBay takedown.
  • Trump Hotels Hit By 3rd Card Breach in 2 Years

    Krebs on Security
    Maybe some of you missed this amid all the breach news recently (I know I did), but Trump International Hotels Management LLC last week announced its third credit-card data breach in the past two years. I thought it might be useful to see these events plotted on a timeline, because it suggests that virtually anyone who used a credit card at a Trump property in the past two years likely has had their card data stolen and put on sale in the cybercrime underground as a result.
  • Experts in Lather Over ‘gSOAP’ Security Flaw

    Krebs on Security
    Axis Communications -- a maker of high-end security cameras whose devices can be found in many high-security areas -- recently patched a dangerous coding flaw in virtually all of its products that an attacker could use to remotely seize control over or crash the devices.

    The problem wasn't specific to Axis, which seems to have reacted far more quickly than competitors to quash the bug. Rather, the vulnerability resides in open-source, third-party computer code that has been used in countless products and technologies (including a great many security cameras), meaning it may be some time before most vulnerable vendors ship out a fix -- and even longer before users install it.
  • Porn Spam Botnet Has Evil Twitter Twin

    Krebs on Security
    Last month KrebsOnSecurity published research into a large distributed network of apparently compromised systems being used to relay huge blasts of junk email promoting "online dating" programs -- affiliate-driven schemes traditionally overrun with automated accounts posing as women. New research suggests that another bot-promoting botnet of more than 80,000 automated female Twitter accounts has been pimping the same dating scheme and ginning up millions of clicks from Twitter users in the process.
  • Thieves Used Infrared to Pull Data from ATM ‘Insert Skimmers’

    Krebs on Security
    A greater number of ATM skimming incidents now involve so-called "insert skimmers," wafer-thin fraud devices made to fit snugly and invisibly inside a cash machine’s card acceptance slot. New evidence suggests that at least some of these insert skimmers -- which record card data and store it on a tiny embedded flash drive are -- equipped with technology allowing it to transmit stolen card data wirelessly via infrared, the same technology built into a television remote control.
  • Adobe, Microsoft Push Critical Security Fixes

    Krebs on Security
    It's Patch Tuesday, again. That is, if you run Microsoft Windows or Adobe products. Microsoft issued a dozen patch bundles to fix at least 54 security flaws in Windows and associated software. Separately, Adobe's got a new version of its Flash Player available that addresses at least three vulnerabilities.
  • Self-Service Food Kiosk Vendor Avanti Hacked

    Krebs on Security
    Avanti Markets, a company whose self-service payment kiosks sit beside shelves of snacks and drinks in thousands of corporate breakrooms across America, has suffered of breach of its internal networks in which hackers were able to push malicious software out to those payment devices, the company has acknowledged. The breach may have jeopardized customer credit card accounts as well as biometric data, Avanti warned.
  • B&B Theatres Hit in 2-Year Credit Card Breach

    Krebs on Security
    B&B Theatres, a company that owns and operates the 7th-largest theater chain in America, says it is investigating a breach of its credit card systems. The acknowledgment comes just days after KrebsOnSecurity reached out to the company for comment on reports from financial industry sources who said they suspected the cinema chain has been leaking customer credit card data to cyber thieves for the past two years.
