{"id":"MAL-2026-6427","summary":"Malicious code in leo-connector-redshift (npm)","details":"The `leo-connector-redshift` npm package was compromised as part of the Miasma worm campaign targeting the LeoPlatform npm ecosystem. On June 24, 2026, 20 LeoPlatform packages were published within a 3-second window by a threat actor who had taken over the npm account `czirker` belonging to the LeoPlatform organization.\n\nThe malicious payload is triggered automatically during `npm install` via a `binding.gyp` file using node-gyp command expansion (`\u003c!(node index.js \u003e /dev/null 2\u003e&1 && echo stub.c)`), which bypasses lifecycle script scanners. The replaced `index.js` (~5.2 MB, obfuscated with ROT-N + AES-128-GCM encryption) deploys a multi-stage worm with the following capabilities:\n\n- Credential theft: Targets npm, GitHub, PyPI, RubyGems, Kubernetes, HashiCorp Vault, AWS (IAM keys, Secrets Manager, IMDS), 1Password, JFrog Artifactory, and SSH keys.\n- AI tool targeting: Exfiltrates configuration files for Claude, Cursor, Gemini, and VS Code.\n- Worm propagation: Enumerates npm packages and auto-publishes version bumps to spread to other maintainers in the ecosystem.\n- GitHub persistence: Creates orphan `snapshot-\u003chex\u003e` branches with fake \"Dependabot Updates\" workflows to maintain access after initial compromise.\n\nAny system that installed this version should be considered fully compromised. Rotate all secrets immediately from a separate, clean machine. See the linked SafeDep report for full payload analysis, indicators of compromise, and remediation guidance.\n\n---\n_-= Per source details.

Because a binding.gyp is present, npm implicitly invokes `node-gyp rebuild` during install, and node-gyp/GYP evaluates `\u003c!(...)` expressions as shell commands during the configure step. This causes the embedded command to execute automatically on `npm install` with no declared lifecycle script in package.json and no explicit user action. The construct fires on default install and provides the maintainer of this version a generic mechanism to run arbitrary shell on every installer's machine.\n","modified":"2026-06-25T08:01:25.246437708Z","published":"2026-06-24T23:04:55Z","database_specific":{"iocs":{"urls":["https://safedep.io/miasma-worm-hits-leoplatform-20-npm-packages/"]},"malicious-packages-origins":[{"sha256":"808b84100db5bf11527a7c9f406522f24c4dd9a1ff25f71f0068c1b672da3cbb","id":"IN-MAL-2026-007474","source":"amazon-inspector","import_time":"2026-06-25T07:47:50.899948883Z","modified_time":"2026-06-25T06:30:35Z","versions":["3.0.6"]}]},"references":[{"type":"ARTICLE","url":"https://safedep.io/miasma-worm-hits-leoplatform-20-npm-packages/"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/leo-connector-redshift/v/3.0.6"}],"affected":[{"package":{"name":"leo-connector-redshift","ecosystem":"npm","purl":"pkg:npm/leo-connector-redshift"},"versions":["3.0.6"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/leo-connector-redshift/MAL-2026-6427.json","cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"},{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"indicators":{"package_integrity":[{"filename":"leo-connector-redshift-3.0.6.tgz","hashes":{"sha1":"888094a9b842cfe98e8e24c8f729be1fb6384563","sha512_sri":"sha512-AEwwO99U4UYKu8gHyN8HSff6BunoqeNXOenySzLw68Ejr7oVmpUAeOr4278VOImPqZEt6SYqlnYXlCIyrXvp0w=="}}],"evidence_files":[{"sha256":"32d1bc728d8e504952083a6adc488c309a401c7df4dc8f47b382ce32e4aebe21","tlsh":"48c08c3ca9380d1029d958285168d402a4b142a3494e2a81fade60284fa840b2898bad","path":"binding.gyp"}]}}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"SafeDep","contact":["https://safedep.io"],"type":"FINDER"}]}
