Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-4725/ (Markdown: https://insights.sbomify.com/MAL-2026-4725/index.md)","id":"MAL-2026-4725","markdown":"https://insights.sbomify.com/MAL-2026-4725/index.md","name":"MAL-2026-4725","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"package.json declares \"preinstall\": \"./dist/runtime.node\", causing npm to execute a ~976 KB packed binary on every install. The file uses the `.node` extension typically reserved for Node.js native addons loaded via require()/process.dlopen, but here it is invoked directly as a shell command — not loaded as an addon. The binary is opaque (mostly non-ASCII, packed/obfuscated) and contains strings indicating HTTP networking (HTTP/1.1, POST, DELETE), environment-variable enumeration (USERPROFILE, PATH, LANG), TLS, and RSA/Ed25519 cryptography. There is no shipped source, no node-gyp/prebuild-install scaffolding, and no documented purpose for executing a binary at install. The combination of (a) lifecycle-hook execution of a shipped opaque binary, (b) misleading `.node` extension on a non-addon executable, and (c) embedded networking + env-scraping + crypto capability strings matches the dropper/credential-stealer fingerprint. On `npm install`, attacker-controlled code runs with the installer's privileges and has the capability to exfiltrate environment variables and credentials.\n\nThis package was compromised as part of the IronWorm campaign. This campaign executes a malicious binary payload during installation via a preinstall hook. The payload is a Rust-built infostealer that targets developer environments, scanning for and harvesting credentials related to cloud providers, object storage, databases, source-control, package registries, and AI developer tools. It also targets cryptocurrency wallets, specifically injecting a malicious JavaScript hook into the Exodus desktop wallet to capture passwords and recovery phrases. Furthermore, the malware exhibits worm-like behavior by stealing GitHub and NPM credentials to push malicious updates to the victim's repositories and publish trojanized packages, and it uses an eBPF-based kernel rootkit to hide its processes and network connections on Linux systems.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in weavedb-sdk-node (npm)","id":"MAL-2026-4725","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"weavedb-sdk-node","purl":"pkg:npm/weavedb-sdk-node","source":"MAL-2026-4725"}],"products":null,"published":"2026-05-26","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-4725/"}
