Yet another aggrieved bug hunter has leaked a vulnerability affecting a Microsoft product after becoming disillusioned with the company’s handling of security reports. Ammar Askar dropped a proof of concept (PoC) exploit for a Visual Studio Code (VS Code) flaw within just an hour of disclosing it to “an old contact” at the open source platform, according to his account of things. The vulnerability

Even ransomware cartels make mistakes, and in this case, it was a biggie that could have landed the responsible crim in a Russian gulag: accidentally infecting a company located in a Commonwealth of Independent States country. In what threat-hunter Dominic Alvieri deemed the ransom “dumbass of the day,” Nova, the affiliate program for ransomware crew RAlord, on Tuesday issued an apology to Eriell

Bug hunting has become a whole lot more exciting in recent months with both Anthropic and OpenAI touting their latest models (that also happen to be super-scary exploit machines). On Tuesday, as Anthropic announced a fourfold expansion to its Mythos preview program, Cisco jumped into the fray, praising the transformative power of AI - but without disclosing how many bugs the latest frontier models
Russia's domestic spy agency says it has uncovered a sprawling foreign espionage operation that allegedly turned the smartphones of senior Russian officials into pocket-sized surveillance devices, though it has so far offered little in the way of evidence.

Security researchers on Monday found dozens of Red Hat npm package releases infected with the Mini Shai-Hulud worm that TeamPCP cybercriminals recently open-sourced.

The biggest threat to America’s midterm elections in November likely isn’t foreign attackers hacking US voting machines. Phishing and election-official impersonation are the bigger risks, according to Check Point, which documented more than 5,000 election-themed domains registered between April and May. These domains can be used by attackers for phishing, impersonation, fraud, misinformation, or i

The British government wants stronger protection for subsea internet cables following a surge in Russian activity near UK waters, but its latest proposals lean heavily on fines and prison sentences rather than direct defensive action.

A single npm user on Thursday published 14 malicious packages within a four-hour window, all mimicking popular OpenSearch, Elasticsearch, DevOps, and environment-configuration libraries, according to Microsoft. It’s the latest in a seemingly never-ending string of supply chain attacks targeting developer tools, and stealing cloud credentials and CI/CD pipeline secrets in its wake. Using a newly cr

EXCLUSIVE ChatGPT can’t tell its own generated content from attacker-controlled Markdown pulled from external sources, according to a researcher who found the prompt injection technique and reported it to OpenAI.

Russia-linked cyber espionage crews appear to be using AI tools to help build malware, spin up infrastructure, and craft lures for attacks on Ukrainian targets.

Microsoft, for its part, finally responded to the security researcher and

Windows Server 2016 might be long in the tooth but that isn't about to stop Microsoft breaking stuff. The May 12 security update introduced another bug for administrators to worry about.

In the notes for the glitch, Microsoft wrote: "When the ho
