You don't run code on people who haven't agreed to it. That norm has ended careers. Claude uploaded live malware to PyPI in a botched eval and 15 real systems ran it. It even maneuvered around restrictions to squat a phantom dependency and breached 3 orgs. www.bleepingcomputer.com/news/securit...

Anthropic's Claude breached 3 orgs, uploaded PyPI malware during tests

One of Anthropic's Claude models built and uploaded a malicious Python package to PyPI during a botched security evaluation, where it ran on 15 real systems and stole credentials from a security vendo...

[1/2] A VS Code extension called 'Markdown All Pro' impersonates a legit one with 14 million installs. Installing it ships your machine's details off-box and opens a channel the operator can feed anything to later, no update to the extension needed!

Remember ClaudeBleed? The Claude for Chrome fix that didn't fix it. 2 new flaws, reported in May, marked resolved. 8 versions later, both still reproduce! Any other extension you've installed can push Claude into reading your Gmail. 🔗 Full breakdown: www.manifold.security/blog/claude-...

An AI code reviewer just approved a pull request that steals your secrets. It never saw it coming as the attack was hidden in a PNG. Researchers put the malicious instruction inside an image. The reviewer never opened it, so the poisoned PR merged clean! www.bleepingcomputer.com/news/securit...

'Ghostcommit' hides prompt injection in images to fool AI agents, steal secrets

A PNG hiding a prompt injection could steal your repo's secrets, researchers demonstrate. The technique, dubbed 'Ghostcommit,' slipped past AI code reviewers CodeRabbit and Bugbot, which never open im...

Everyone's covering the UK's under-16 social media ban. The under-covered bit: enforcing it means opening any new account will require an ID or face scan, effectively ending anonymity. Experts warn circumvention is easy and your biometric data is at risk. www.bleepingcomputer.com/news/securit...

UK to require ID or face scan before you can make social media accounts

Opening a new social media account in the UK will soon mean proving you're over 16 with an ID upload or a facial age scan, under a government ban on under-16s taking effect in spring 2027. Security ex...

Every useful AI agent today reads private data, processes untrusted content, and communicates externally. By design. That's also the exact profile researchers used to flag as a near-guaranteed sign of exploitation. So, how do you separate signal from noise? www.csoonline.com/article/4184...

5 runtime signals for catching a compromised AI agent

Once a signal of exploitation risk, Willison’s ‘lethal trifecta’ describes the baseline operations of every AI agent today. As a result, agent security is no longer architectural. Here’s what to watch...

US gov ordered Anthropic to pull Fable 5 + Mythos 5 for all "foreign nationals" ... so effectively worldwide. The trigger being a narrow jailbreak where you ask the model to read a codebase and fix bugs. But, the capability is anyway widely available (from other models like GPT-5.5).

We disclosed a critical flaw in n8n-mcp (120k+ weekly npm downloads). On shared multi-tenant setups, one user could read everyone else's workflow backups, API keys and tokens included, or *wipe them all* in a single call. Just by guessing a number. CVSS 9.6. Found by Franciso Rosales. 🧵

A trojanized Bitwarden npm version appeared for 90 minutes last month. 9 days later it got a CVE—after the package was already pulled. That's an incident response notification, not what CVEs were originally built for. Agentic AI makes this gap much worse. www.csoonline.com/article/4173...

Why some security fixes never reach your vulnerability dashboard

CVE was built to track code flaws with fixes. It’s now being stretched to cover malware and supply chain incidents that don’t fit. Agent infrastructure and AI assets are where that drift becomes struc...

We scanned 19,000+ AI agent skills. One enterprise scanner flagged 40%+ as malicious. Most were fine. A skill called "derp" passed two of three scanners clean. It instructs agents to silently produce broken code, and blame the developer's environment if they get suspicious.

Who are AI safety guardrails actually protecting? I've been researching this for a few weeks, and the honest answer is... not always the right people. Defenders and security researchers often face friction, while attackers just walk around safety guardrails: www.csoonline.com/article/4138...

When AI safety constrains defenders more than attackers

AI guardrails increasingly block legitimate security work while attackers bypass restrictions with ease. For CISOs, this asymmetry creates blind spots in defensive capabilities.

Responsible disclosure is built on an assumption that "doing the right thing" would = timely action, fair treatment, and maybe a bounty reward. Lately, that assumption is collapsing. For CISOs, this is gradually becoming a risk management nightmare. www.csoonline.com/article/4124...

When responsible disclosure becomes unpaid labor

An incentive gap is undermining responsible disclosure. For CISOs, this is gradually evolving into a risk management nightmare.

A NationStates game player found a critical vulnerability but then crossed a line: he copied production data and app code. Finding a flaw is enough. Demonstrate it safely, report it and stop there. Holding data isn't clever, ever. www.bleepingcomputer.com/news/securit...

NationStates confirms data breach, shuts down game site
