The actual exports are harvest-and-upload primitives. lib/collect.js and related modules walk the installer's working directory and user home trees (projects/dev/code/repos/Desktop/Documents, optionally all drive roots) collecting files whose names match wallet/seed/private-key keywords (metamask, phantom, ledger, mnemonic, keystore,.env,.pem,.p12, etc.). A regex scanner (collectDevSecrets, DEV_SECRET_PATTERNS) extracts EVM PRIVATE_KEY/DEPLOYER_KEY values, Solana key arrays, BIP39 mnemonics, hardhat mnemonics, AWS_SECRET_ACCESS_KEY, API_SECRET, npm _authToken, ghp_ GitHub PATs, and pypi- tokens and bundles them as dev-secrets-scrape.txt. gatherShellHistory reads.bash_history,.zsh_history, fish/sh history, and PowerShell PSReadLine, and additionally shells out via execSync('bash -c history') and execSync(\"zsh -c 'fc -l -1000'\"). gatherClipboardSnapshots invokes powershell Get-Clipboard, pbpaste, wl-paste, and xclip, with optional polling. All collected artifacts are multipart-POSTed to https://trabalhos-flax.vercel.app/api/v1. Auxiliary code base64-decodes string constants (including 8.8.8.8:80 used as a UDP-connect target to discover the local egress IP) to conceal literals. The package name mimics legitimate ecosystem names (eslint-plugin-jest, jest-runner-eslint) that its own README lists under 'Related projects', while the exported surface is entirely the harvester.\n\n## Source: ghsa-malware (8131394ae9c99a6353e0b06148add947773e8a65aa2f635020bf2c43028c6b7b)\nAny computer that has this package installed or running should be considered fully compromised.
