  • Equifax or Equiphish?

    Krebs on Security
    More than a week after it said most people would be eligible to enroll in a free year of its TrustedID identity theft monitoring service, big three consumer credit bureau Equifax has begun sending out email notifications to people who were able to take the company up on its offer. But in yet another security stumble, the company appears to be training recipients to fall for phishing scams.
  • Experian Site Can Give Anyone Your Credit Freeze PIN

    An alert reader recently pointed my attention to a free online service offered big-three credit bureau Experian that allows anyone to request the personal identification number (PIN) needed to unlock a consumer credit file that was previously frozen at Experian.
  • Equifax Breach: Setting the Record Straight

    Krebs on Security
    Bloomberg published a story this week citing three unnamed sources who told the publication that Equifax experienced a breach earlier this year which predated the intrusion that the big-three credit bureau announced on Sept. 7. To be clear, this earlier breach at Equifax is not a new finding and has been a matter of public record for months. Furthermore, it was first reported on this Web site in May 2017.
  • Equifax Hackers Stole 200k Credit Card Accounts in One Fell Swoop

    Krebs on Security
    Visa and MasterCard are sending confidential alerts to financial institutions across the United States this week, warning them about more than 200,000 credit cards that were stolen in the epic data breach announced last week at big-three credit bureau Equifax. At first glance, the private notices obtained by KrebsOnSecurity appear to suggest that hackers were first able to steal credit card numbers from Equifax starting in November 2016. But Equifax says the accounts were all stolen at the same time -- when hackers accessed the company's systems in mid-May 2017.
  • Adobe, Microsoft Plug Critical Security Holes

    Krebs on Security
    Adobe and Microsoft both on Tuesday released patches to plug critical security vulnerabilities in their products. Microsoft's patch bundles fix close to 80 separate security problems in various versions of its Windows operating system and related software, including two vulnerabilities that already are being exploited in active attacks. Adobe's new version of its Flash Player software fixes two flaws that malware or attackers could use to seize remote control over vulnerable computers with no help from users.
  • Ayuda! (Help!) Equifax Has My Data!

    Krebs on Security
    Equifax last week disclosed a historic breach involving Social Security numbers and other sensitive data on as many as 143 million Americans. The company said the breach also impacted an undisclosed number of people in Canada and the United Kingdom. But the official list of victim countries may not yet be complete: According to information […]
  • The Equifax Breach: What You Should Know

    Krebs on Security
    It remains unclear whether those responsible for stealing Social Security numbers and other data on as many as 143 million Americans from big-three credit bureau Equifax intend to sell this data to identity thieves. But if ever there was a reminder that you -- the consumer -- are ultimately responsible for protecting your financial future, this is it. Here's what you need to know and what you should do in response to this unprecedented breach.
  • Equifax Breach Response Turns Dumpster Fire

    Krebs on Security
    I cannot recall a previous data breach in which the breached company’s public outreach and response has been so haphazard and ill-conceived as the one coming right now from big-three credit bureau Equifax, which rather clumsily announced Thursday that an intrusion jeopardized Social security numbers and other information on 143 million Americans.
  • Breach at Equifax May Impact 143M Americans

    Krebs on Security
    Equifax, one of the "big-three" U.S. credit bureaus, said today that a data breach at the company may have affected 143 million Americans, jeopardizing consumer Social Security numbers, birth dates, addresses and some driver's license numbers.
  • Who Is Marcus Hutchins?

    Krebs on Security
    In early August 2017, FBI agents in Las Vegas arrested 23-year-old U.K. resident Marcus Hutchins on suspicion of authoring and/or selling “Kronos,” a strain of malware designed to steal online banking credentials. Hutchins was virtually unknown to most in the security community until May 2017, when a British newspaper revealed him as the “accidental hero” who inadvertently halted the global spread of WannaCry, a ransomware contagion that had taken the world by storm just days before.

    Relatively few knew it before his arrest, but Hutchins for many years authored the popular cybersecurity blog MalwareTech. When this fact became more widely known — combined with his hero status for halting Wannacry — a great many MalwareTech readers quickly leapt to his defense to denounce his arrest. They reasoned that the government was overstepping on flimsy evidence, noting that Hutchins has worked tirelessly to expose cybercriminals and their malicious tools. To date, some 226 supporters have donated more than $14,000 to his defense fund.

    At first, I did not believe the charges against Hutchins would hold up under scrutiny. But as I began to dig deeper into the history tied to dozens of hacker forum pseudonyms, email addresses and domains he apparently used over the past decade, a very different picture began to emerge.

    In this post, I will attempt to describe and illustrate more than three weeks’ worth of connecting the dots from what appear to be Hutchins’ earliest hacker forum accounts to his real-life identity. The clues suggest that Hutchins began developing and selling malware in his mid-teens — only to later develop a change of heart and earnestly endeavor to leave that part of his life squarely in the rearview mirror.
