The package self-describes as a pure-JavaScript decentralized-DB SDK, so a native Linux helper has no documented purpose during install. No source code (.c/.cc/.rs/binding.gyp), no node-gyp or prebuild-install machinery, and no hash/signature verification accompanies the binary; its bytes are packed (fragmented, non-contiguous strings characteristic of UPX or a custom packer), preventing review. Extracted strings reveal HTTP/1.1, POST, DELETE, https://, USERPROFILE, LIBBPF (eBPF), PTRACE, and TLS/cipher routines — capabilities entirely inconsistent with a JavaScript SDK and consistent with a credential-harvest / surveillance / RCE payload. On `npm install weavedb-sdk-base` on Linux, this binary executes with the installer's UID before dependency resolution completes, giving the publisher arbitrary native code execution on the installer's machine.\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","affected":[{"package":{"ecosystem":"npm","name":"weavedb-sdk-base"},"versions":["0.21.1"],"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":[{"path":"package.json","sha256":"d2c81ff767773fd344e432f72b1235b9a904b918be9d4e77c94e516424cf3246","tlsh":"5d213870de68cf7319e422a82426515661219a178d48f88d33d2b74d0f8daef317aa5e"},{"path":"bin/install-deps","sha256":"36abd242ddaa27f0160c539377a0e92cf781c1695137850acc87e3892b436d36","tlsh":"0c2533ab0025062b904d957a58963bd279c17c81afcc3662664dae742fb59c3cf63fc3"}],"package_integrity":[{"filename":"weavedb-sdk-base-0.21.1.tgz","hashes":{"sha1":"766facdb5f40c65471274232b9d756049f025ba9","sha512_sri":"sha512-7Ooi9SvZjEjJu1F+5vfGveLacMLHuAzZgjc/Q3t5VTHkbSv+NGKTGiND0smCXbybxHnG/SnVL8rbpB3tIrB9hA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/weavedb-sdk-base/v/0.21.1"},{"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/"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["actran@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","sha256":"40b4b0c5f79c0370a77c3b559b70389ffee591aa22c76ca15c4077fe95b5078e","import_time":"2026-05-26T05:53:22.555392488Z","id":"IN-MAL-2026-004835","modified_time":"2026-05-26T01:01:28Z","versions":["0.21.1"]},{"source":"google-open-source-security","sha256":"146faaf0d97c6a533a969bc3f3f117811f9317dc865ed4ab37f1679842ddeaae","import_time":"2026-06-04T22:42:01.227855Z","modified_time":"2026-06-04T22:28:51.769005667Z","versions":["0.21.1"]}]}}
