Sentinel-9.9.9 depconf squat; preinstall `node index.js || true` exfils env secrets (mnemonic/private-key/blockfrost) to raw C2 2.25.140.71:8443/surflending/npm-confusion (same C2).

The script collects host identity (hostname, username, cwd) and iterates `process.env`, filtering for keys matching /key|seed|secret|token|private|mnemonic|password|blockfrost|redis|telegram|batcher/i — i.e., wallet seed phrases, private keys, API tokens, and infrastructure credentials. The collected JSON is HTTPS-POSTed to the bare IP `2.25.140.71:8443` at path `/surflending/npm-confusion`. The package ships no real SDK functionality (description is the placeholder `flow-lending-sdk SDK`, version is `9.9.9`), and the exfil URL path explicitly names this as a dependency-confusion attack — almost certainly targeting developers of Cardano/Flow lending infrastructure who expect a private internal package of this name.\n\n## Source: ghsa-malware (0c53f2d309499f7c77e2fc1024ece82ca775f13741abacdcaf4ede50fa6c8e39)\nAny computer that has this package installed or running should be considered fully compromised.
