Attackers Are Hunting High-Impact Node.js Maintainers in a Coordinated Social Engineering Campaign

Since we published our initial analysis of the axios compromise, a deep dive into its hidden blast radius, and a report on the maintainer confirming it was social engineering, maintainers across the Node.js ecosystem have come out of the woodwork to report that they were targeted by the same social engineering campaign. The accounts now span some of the most widely depended-upon packages in the npm registry and Node.js core itself, and together they confirm that axios was not a one-off target.…

Can JavaScript Escape a CSP Meta Tag Inside an Iframe?

Research: Can JavaScript Escape a CSP Meta Tag Inside an Iframe? In trying to build my own version of Claude Artifacts I got curious about options for applying CSP headers to content in sandboxed iframes without using a separate domain to host the files. Turns out you can inject <meta http-equiv="Content-Security-Policy"...> tags at the top of the iframe content and they'll be obeyed even if subsequent untrusted JavaScript tries to manipulate them. Tags: iframes, security, javascript,…

The Axios supply chain attack used individually targeted social engineering

The Axios team have published a full postmortem on the supply chain attack which resulted in a malware dependency going out in a release the other day, and it involved a sophisticated social engineering campaign targeting one of their maintainers directly. Here's Jason Saayman'a description of how that worked: so the attack vector mimics what google has documented here: https://cloud.google.com/blog/topics/threat-intelligence/unc1069-targets-cryptocurrency-ai-social-engineering they tailored…

Gemma 4: Byte for byte, the most capable open models Four new vision-capable Apache 2.0 licensed reasoning LLMs from Google DeepMind, sized at 2B, 4B, 31B, plus a 26B-A4B Mixture-of-Experts. Google emphasize "unprecedented level of intelligence-per-parameter", providing yet more evidence that creating small useful models is one of the hottest areas of research right now. They actually label the two smaller models as E2B and E4B for "Effective" parameter size. The system card explains: The…

Axios Maintainer Confirms Social Engineering Attack Behind npm Compromise

On March 31, two malicious versions of Axios were briefly published to npm, introducing a dependency that installed a remote access trojan across macOS, Windows, and Linux. We covered the initial attack and its scope earlier, as well as a deeper technical analysis of its hidden blast radius and how dependency resolution expanded its impact exponentially. Now, the project’s lead maintainer has shared additional details about how the compromise occurred. A Targeted Social Engineering Attack # In…

Node.js Drops Bug Bounty Rewards After Funding Dries Up

The Node.js project has paused its long-running bug bounty program after the funding behind it was discontinued, removing a key security incentive from one of the most widely used JavaScript runtimes. For nearly a decade, Node.js participated in the Internet Bug Bounty (IBB) program through HackerOne, offering monetary rewards to researchers who responsibly disclosed security issues. That program is now on hold, leaving Node.js without a funded bounty structure for the first time since 2016.…
