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-2026-6790/ (Markdown: https://insights.sbomify.com/MAL-2026-6790/index.md)","id":"MAL-2026-6790","markdown":"https://insights.sbomify.com/MAL-2026-6790/index.md","name":"MAL-2026-6790","record":{"aliases":["GHSA-86fh-6m37-f9v4"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package name `debugcli` shadows the popular `debug` package, and `index.js` is a thin re-export (`module.exports = require('debug')`) so callers observe legitimate behavior. The real payload runs via `\"postinstall\": \"node install.js\"` in package.json. On install, `install.js` performs: (1) bulk credential-file harvest — reads `~/.aws/credentials`, `~/.aws/config`, `~/.npmrc`, `~/.ssh/config`, `~/.pypirc`, `~/.netrc`, `~/.docker/config.json`, `~/.kube/config`, gcloud application_default_credentials, `.git-credentials`, Azure tokens, composer auth, and walks the current working directory upward collecting `.env`, `.env.local`, `.env.production`, `.env.development`; (2) process.env scraping — iterates `process.env` and filters keys matching TOKEN/SECRET/PASSWORD/API_KEY/AUTH/PRIVATE/AWS_*/GITHUB_*/NPM_*/OPENAI/ANTHROPIC/DATABASE_URL/STRIPE/TWILIO patterns; (3) browser wallet theft — locates Chrome extension Local Extension Settings for MetaMask (extension id `nkbihfbeogaeaoehlefnkodbecgpgknn`) and TrustWallet (`egjidjbpglichdcondbcbdnbeeppgdph`) and archives the vault directories via `powershell Compress-Archive` on Windows or `tar czf... --exclude=LOCK` on Unix; (4) exfiltration — POSTs collected env vars, credential files,.env contents, and wallet archives to `api.telegram.org/bot\u003ctoken\u003e/sendMessage` and `/sendDocument`, with the bot token and chat_id stored as XOR-encoded byte arrays (`ENC_TOKEN`, `ENC_CHAT`) decoded at runtime using the current lodash package version fetched from `registry.npmjs.org/lodash` dist-tags.latest as the XOR key; (5) evasion — `isSandbox()` checks CPU/RAM, hostname regex (`sandbox|malware|virus|sample|cuckoo|any.run|hybrid`), analysis env vars, and HOME directory age, and skips execution on analysis machines; a per-machine hashed lockfile prevents re-execution within 24h; and finally `fs.unlinkSync(__filename)` removes install.js after exfil.\n\nAny computer that has this package installed or running should be considered fully compromised.
