Microsoft identified a large-scale npm supply chain attack by North Korean threat actor Sapphire Sleet, compromising over 140 packages in the Mastra ecosystem. The attackers used a compromised maintainer account to inject a malicious typosquat dependency that executes a cross-platform Node.js implant during installation, leading to cryptocurrency wallet theft, host reconnaissance, and persistent backdoor access.
A targeted supply chain attack attributed to Famous Chollima compromised a development branch of the legitimate PHP package 'roberts/leads' on Packagist. The attackers injected an obfuscated JavaScript loader into a tailwind.js configuration file, which utilizes blockchain RPC infrastructure as a dead drop to retrieve and execute secondary payloads like DEV#POPPER RAT, likely as part of a Contagious Interview developer lure.
CrowdStrike, in collaboration with Google and Shadowserver, successfully dismantled the Glassworm botnet, a highly resilient threat targeting software developers. The threat actors utilized trojanized IDE extensions and malicious package dependencies to deploy GlasswormRAT, leveraging a complex C2 infrastructure spanning the Solana blockchain, BitTorrent DHT, and Google Calendar to maintain persistent access to developer environments.
A widespread supply chain attack compromised hundreds of GitHub repositories by injecting malicious postinstall scripts into package.json files and GitHub Actions workflows. The payload uses curl to download a remote Linux binary disguised as an SSH daemon, primarily targeting PHP projects that bundle JavaScript build tools to bypass standard Composer dependency reviews.
Recent versions of the popular npm package node-ipc (9.1.6, 9.2.3, 12.0.1) were compromised to include an obfuscated credential stealer. The malware executes upon CommonJS module load, harvests sensitive developer and cloud credentials, and exfiltrates the compressed data via DNS TXT queries to attacker-controlled infrastructure.
A critical sandbox escape vulnerability (CVE-2026-26956) in the vm2 Node.js library allows attackers to execute arbitrary OS commands by leveraging WebAssembly.JSTag via VM.run(). The flaw affects versions 0.2.2 through 3.10.4 on Node.js runtimes exposing this tag, prompting the release of vm2 3.10.5 and a free Certified Patch from Socket to remove the tag from the sandbox environment.
The release of pnpm 11 introduces significant supply chain security enhancements, including a default 24-hour minimum release age for packages, the blocking of exotic subdependencies, and a streamlined allowBuilds model. These features are designed to mitigate rapid supply chain attacks, such as the recent Mini Shai-Hulud campaign, by restricting install-time execution and unexpected dependency sources.
The Canadian Centre for Cyber Security released a daily digest highlighting five security advisories. Notably, Ivanti Endpoint Manager Mobile (EPMM) contains an actively exploited vulnerability (CVE-2026-6973), and critical updates were issued for Spring Cloud Config, VM2 Node.js library, Mozilla Firefox, and multiple Broadcom VMware Tanzu products.
The Silver Fox threat group is conducting a phishing campaign targeting organizations in Russia and India with tax-themed lures. The attack chain utilizes a modified RustSL loader featuring geofencing and Phantom Persistence to deploy ValleyRAT. ValleyRAT subsequently downloads a novel Python-based backdoor called ABCDoor, which masquerades as a Tailscale VPN client and provides remote control and screen broadcasting capabilities.
Void Dokkaebi (Famous Chollima) is conducting a self-propagating supply chain campaign targeting software developers via fake job interviews. By tricking victims into cloning malicious repositories, the attackers deploy the DEV#POPPER RAT and weaponize the victim's own code contributions to infect downstream developers and organizational repositories.
Recent supply chain attacks in March 2026, including the compromise of the widely used Axios npm package by North Korean actors and CI/CD targeting by TeamPCP, highlight the increasing threat to the open-source ecosystem. These incidents underscore the necessity of supporting and securing open-source maintainers against sophisticated nation-state social engineering and credential theft campaigns, rather than abandoning open-source architecture.
The Node.js project has paused its bug bounty program following the suspension of the Internet Bug Bounty (IBB) initiative, which provided its funding. The shift highlights ongoing challenges in open-source security funding and the strain caused by high volumes of low-quality, AI-generated vulnerability reports.
On March 31, 2026, the popular Axios npm package was compromised in a supply chain attack attributed to North Korean threat actor Sapphire Sleet. Malicious versions 1.14.1 and 0.30.4 included a fake dependency that silently executed a post-install script to download and install OS-specific Remote Access Trojans (RATs) on Windows, macOS, and Linux systems.
A critical supply chain attack compromised the popular Axios npm package, utilizing a malicious transitive dependency to execute cross-platform payloads during installation. The attack targets Linux, Windows, and macOS systems, deploying OS-specific Remote Access Trojans (RATs) capable of host profiling, command execution, and follow-on payload delivery. Detection engineering efforts should focus on anomalous process ancestry, such as Node.js spawning native OS shells to retrieve and background remote payloads.
Node.js is transitioning from a biannual to an annual major release cycle starting with version 27, retiring the legacy odd/even LTS model. This strategic shift aims to reduce maintainer fatigue, streamline security backports, and align with industry-standard predictable release schedules.
