{"id":"MAL-2026-4725","summary":"Malicious code in weavedb-sdk-node (npm)","details":"\n---\n_-= Per source details.

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\n## Source: google-open-source-security (146faaf0d97c6a533a969bc3f3f117811f9317dc865ed4ab37f1679842ddeaae)\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.\n","modified":"2026-06-04T23:16:43.166909899Z","published":"2026-05-26T00:59:03Z","database_specific":{"malicious-packages-origins":[{"sha256":"59e557cd0501bb17925a19c5d3525fdf18f286b21750a44c0164eb7e165f55d9","versions":["0.45.3"],"import_time":"2026-05-26T05:53:18.858488529Z","id":"IN-MAL-2026-004805","modified_time":"2026-05-26T00:59:03Z","source":"amazon-inspector"},{"sha256":"146faaf0d97c6a533a969bc3f3f117811f9317dc865ed4ab37f1679842ddeaae","versions":["0.45.3"],"import_time":"2026-06-04T22:42:01.227855Z","modified_time":"2026-06-04T22:28:51.769005667Z","source":"google-open-source-security"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/weavedb-sdk-node/v/0.45.3"},{"type":"ARTICLE","url":"http://www.ox.security/blog/ironworm-supply-chain-malware-hits-npm/"},{"type":"ARTICLE","url":"https://research.jfrog.com/post/iron-worm-shai-hulud-rustier-cousin/"}],"affected":[{"package":{"name":"weavedb-sdk-node","ecosystem":"npm","purl":"pkg:npm/weavedb-sdk-node"},"versions":["0.45.3"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"sha256":"e2f628fd69ecd3176b2c2b266b218bf14d56a5317715c86507ddff41a87bf64f","tlsh":"16014971cd64dab319d821e9a87701826122d8578d4cfc8d33c3a31d4b5d9fb21be29d","path":"package.json"},{"sha256":"36abd242ddaa27f0160c539377a0e92cf781c1695137850acc87e3892b436d36","tlsh":"0c2533ab0025062b904d957a58963bd279c17c81afcc3662664dae742fb59c3cf63fc3","path":"dist/runtime.node"}],"package_integrity":[{"filename":"weavedb-sdk-node-0.45.3.tgz","hashes":{"sha1":"22bda32e43978bd4b4a3700530f3d9f331a1ff29","sha512_sri":"sha512-ZUoRH+PHpzDmwLz9Tpf84XMB3bG5sj8qU3f32OTdHEvvH6kyNV72bT/c/I63Rrb2a1yNCfnxMjE7GwUmSFC0EA=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/weavedb-sdk-node/MAL-2026-4725.json"}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["actran@amazon.com"],"type":"FINDER"}]}
