A whistleblower at the National Labor Relations Board (NLRB) alleged last week that denizens of Elon Musk's Department of Government Efficiency (DOGE) siphoned gigabytes of data from the agency's sensitive case files in early March. The whistleblower said accounts created for DOGE at the NLRB downloaded three code repositories from GitHub. Further investigation into one of those code bundles shows it is remarkably similar to a program published in January 2025 by Marko Elez, a 25-year-old DOGE employee who has worked at a number of Musk's companies.
A 23-year-old Scottish man thought to be a member of the prolific Scattered Spider cybercrime group was extradited last week from Spain to the United States, where he is facing charges of wire fraud, conspiracy and identity theft. U.S. prosecutors allege Tyler Robert Buchanan and co-conspirators hacked into dozens of companies in the United States and abroad, and that he personally controlled more than $26 million stolen from victims.
A employee at Elon Musk's artificial intelligence company xAI leaked a private key on GitHub that for the past two months could have allowed anyone to query private xAI large language models (LLMs) which appear to have been custom made for working with internal data from Musk's companies, including SpaceX, Tesla and Twitter/X, KrebsOnSecurity has learned.
A Texas firm recently charged with conspiring to distribute synthetic opioids in the United States is at the center of a vast network of companies in the U.S. and Pakistan whose employees are accused of using online ads to scam westerners seeking help with trademarks, book writing, mobile app development and logo designs, a new investigation reveals.
Microsoft on Tuesday released software updates to fix at least 70 vulnerabilities in Windows and related products, including five zero-day flaws that are already seeing active exploitation. Adding to the sense of urgency with this month's patch batch from Redmond are fixes for two other weaknesses that now have public proof-of-concept exploits available.
In what experts are calling a novel legal outcome, the 22-year-old former administrator of the cybercrime community Breachforums will forfeit nearly $700,000 to settle a civil lawsuit from a health insurance company whose customer data was posted for sale on the forum in 2023. Conor Brian Fitzpatrick, a.k.a. "Pompompurin," is slated for resentencing next month after pleading guilty to access device fraud and possession of child sexual abuse material (CSAM).
KrebsOnSecurity last week was hit by a near record distributed denial-of-service (DDoS) attack that clocked in at more than 6.3 terabits of data per second (a terabit is one trillion bits of data). The brief attack appears to have been a test run for a massive new Internet of Things (IoT) botnet capable of launching crippling digital assaults that few web destinations can withstand. Read on for more about the botnet, the attack, and the apparent creator of this global menace.
The U.S. government today unsealed criminal charges against 16 individuals accused of operating and selling DanaBot, a prolific strain of information-stealing malware that has been sold on Russian cybercrime forums since 2018. The FBI says a newer version of DanaBot was used for espionage, and that many of the defendants exposed their real-life identities after accidentally infecting their own systems with the malware.
Authorities in Pakistan have arrested 21 individuals accused of operating "Heartsender," a once popular spam and malware dissemination service that operated for more than a decade. The main clientele for HeartSender were organized crime groups that tried to trick victim companies into making payments to a third party, and its alleged proprietors were publicly identified by KrebsOnSecurity in 2021 after they inadvertently infected their computers with malware.
The U.S. government today imposed economic sanctions on Funnull Technology Inc., a Philippines-based company that provides computer infrastructure for hundreds of thousands of websites involved in virtual currency investment scams, commonly known as “pig butchering." In January 2025, KrebsOnSecurity detailed how Funnull was being used as a content delivery network that catered to cybercriminals seeking to route their traffic through U.S.-based cloud providers.
