At least two distinct threat actors are weaponizing a novel evasion technique called OAuth client ID spoofing in cloud campaigns, while slipping past telemetry. The activity allows users to enumerate user accounts and validate stolen credentials in Microsoft Entra ID environments, without ever generating a successful sign-in event that would otherwise alert defenders. And bad actors have begun

xAI's Grok Build coding CLI was uploading entire Git repositories, full commit history and all, to a Google Cloud Storage bucket run by xAI, not just the files a coding task needed. A researcher publishing as cereblab, testing version 0.2.93, captured one of those uploads, cloned the git bundle out of the intercepted request, and pulled back a file the agent had been told in plain terms not

The U.S. Treasury Department's Office of Foreign Assets Control (OFAC) has designated two individuals and a VPN service provider for enabling ransomware actors' and other cybercriminals' malicious activities, including ransomware attacks against Americans. The VPN, named First VPN Service (1VPNS), has been accused of offering its tools to ransomware groups, along with its 45-year-old Ukrainian

A campaign of 148 npm packages disguised as student web proxies turned visitors' browsers into a distributed denial-of-service botnet for roughly two weeks in May, according to new research from JFrog. The packages did not go after the developers who might install them. The operators used the registry as free hosting for a booby-trapped proxy site and let the students who came to dodge

Attackers whose methods line up with the data-extortion group ShinyHunters have spent the past year walking into corporate Salesforce environments without exploiting a single flaw in the platform. The way in has been the trust the organization had already extended, usually through the OAuth connections that tie Salesforce to the apps and third-party vendors around it. In

In some companies, engineers are building defense and attack tools to test the potential of artificial intelligence for cybersecurity — and its threat.

Cybersecurity researchers have flagged a new macOS information stealer called CrashStealer that's capable of harvesting sensitive data from compromised systems. Unlike other information stealers that are built on AppleScript droppers or Objective-C-based wrappers, CrashStealer is implemented in native C++, according to Jamf Threat Labs. "It validates the victim's login password locally before

Google and Microsoft have pulled ModHeader, a popular header-editing extension with roughly 1.6 million installs across Chrome and Edge, after researchers found a hidden browsing-history collector built into its official store version. The collector was dormant. An empty allow-list kept it switched off, and no proof has emerged that it ever gathered or sent a single browsing domain. The

Somewhere right now, a security tool is quietly finding bugs faster than any human can fix them. That's supposed to be the good news. The catch is that the attackers have the same tools, pointed the other way, and they don't file tickets. That's the shape of this week. Trusted code turns on the people who installed it. Old bugs from last year are still landing because the fix sat in a queue too

The Cybersecurity and Infrastructure Security Agency (CISA) has issued a postmortem on a data leak in which a contractor published dozens of internal CISA credentials -- including AWS Govcloud keys -- in a public GitHub repository for almost six months before being notified by KrebsOnSecurity. Experts say the gaps identified in the agency's initial response provide important lessons that all security teams should absorb.

Give an AI assistant a memory and access to your inbox, and you hand an attacker a way to rewrite what it thinks it knows about you. A single email can trick that agent into saving a false "fact" about the user, hide the change, and quietly steer its answers in later sessions. When it works, the person reads an ordinary-looking reply and never learns their assistant was tampered with. The
