The package's main file (index.js) is heavily obfuscated using obfuscator.io-style string-array rotation, base64 fragments, and per-byte XOR decoders (e.g. H(a0) with key k=[0x70,0xa0,0x89,0x48]) that hide strings such as 'package.json', 'node_modules', '.vscode', 'npm i --silent', 'nohup', 'cd', and 'f.js'. On require(), it collects host identifiers — os.hostname(), os.userInfo().username, os.platform(), Date.now(), process.argv[1] — and beacons them as {ts,type,hid,ss,cc} to a hardcoded C2 endpoint whose host is reassembled at runtime from obfuscated constant arrays (X/z) to evade static detection. The C2 response is used to fetch a second-stage JavaScript payload via GET '<host>/f/<R>', which is written to ~/.vscode/f.js along with a fake package.json; the package then runs cd "<dir>" && npm i --silent and spawns node f.js detached (with nohup on Linux) to persist execution. A setInterval retries the beacon on failure. The package's advertised purpose ("database-security-scanner") is a cover story — package.json has empty author/description/license and no database-scanning code exists; the entire module is the dropper. Any installer that requires this package executes attacker-supplied code fetched at runtime with no hash verification, hidden staging in ~/.vscode, and detached persistence.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
