Is Shai-Hulud Back? Compromised Bitwarden CLI Contains a Self-Propagating npm Worm

Version 2026.4.0 of the widely-used @bitwarden/cli npm package (78,000 weekly downloads) has been identified as malicious. The package contains a sophisticated multi-stage credential theft worm that explicitly names itself "Shai-Hulud: The Third Coming", a direct callback to previous Shai-Hulud supply chain campaigns, and targets developer credentials including SSH keys, cloud secrets, and even MCP configuration files.

Emerging Threat: Axios npm Supply Chain Attack Drops Remote Access Trojan (RAT)

On March 31, 2026, two malicious versions of axios were published to npm, , using credentials stolen from a lead axios maintainer. The attacker injected a hidden dependency into both releases that drops a remote access trojan (RAT) on any machine that ran npm install during the exposure window. No CVE identifier has been assigned at the time of writing. The malicious dependency executes automatically at install time via a postinstall hook, without any action by the developer.

Axios npm Package Compromised: Supply Chain Attack Delivers Cross-Platform RAT

On March 31, 2026, two malicious versions of axios, the enormously popular JavaScript HTTP client with over 100 million weekly downloads, were briefly published to npm via a compromised maintainer account. The packages contained a hidden dependency that deployed a cross-platform remote access trojan (RAT) to any machine that ran npm install (or equivalent in other package managers like Bun) during a two-hour window. The malicious versions (1.14.1 and 0.30.4) were removed from npm by 03:29 UTC.

CVE-2025-55131: Node.js Memory Exposure Risk

Node.js patched a serious vulnerability (CVE-2025-5513) that could expose uninitialized memory and leak secrets like tokens or application data due to a race condition in the buffer allocation logic. This vulnerability affects the vm module with timeouts and is part of a broader coordinated security update across all active Node.js release lines.

Shai-Hulud: The Second Coming Hits npm Users

Once again, the npm supply chain has been compromised, putting developers relying on these vital open source components at risk. On November 24th, a sophisticated attack that borrows techniques from the Shai-Hulud malware used in the npm hijacking this past September was discovered. This is not an isolated incident. It’s a continuation of an existing campaign that is now abusing CI/CD pipelines, and GitHub automation to spread faster and steal more secrets than before.

Shai-Hulud npm supply chain attack - new compromised packages detected

(Nov 24, 2025) JFrog continues to track, provide research and document another wave of the Shai-Hulud Software Supply Chain Attack which was originally reported by the JFrog Security Research team on 16-Sep-2025. Following the initial campaign, threat actors have returned with more advanced tactics, compromising an additional 796 new malicious packages across leading public registries.

Top 10 Node.js Development Companies to Hire Skilled Developers

Slow releases, sluggish web apps, and clunky user experiences can stall growth, frustrate customers, and make promising digital products lose momentum. Many businesses struggle with legacy stacks that are hard to scale, costly to maintain, and too slow to keep pace with modern feature demands. Node.js changes this equation by enabling fast, event-driven, and scalable backends that handle high traffic and real-time interactions with ease. Its vast ecosystem, reusable components, and JavaScript end-to-end approach help teams ship features faster, reduce context switching, and improve overall performance.

Malicious NPM Package Found Targeting GitHub By Typosquatting on GitHub Action Packages

The package states it is for the GitHub Actions Toolkit, which has a legitimate npm package @actions/artifact. Therefore this malware package is a clear typosquat with the swapping of the letters “ti” for “it”. We took a look at the “harness” binary as indicated in version 4.0.13.
