Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Host compromise, private-key exfiltration, and theft of Ethereum funds. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 1.0.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The source directly implements credential theft, remote command execution, C2 communication, and wallet draining; missing declared dependencies may impair execution but do not change its malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-09T13:05:03.361Z - **Finished:** 2026-08-09T13:05:33.180Z - **Download time:** 252 ms - **Static scan time:** 58 ms - **AI review time:** 29509 ms - **Total time:** 29819 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing index.js starts host identification, encrypted C2 registration, command polling, and delayed wallet-key harvesting. Harvested keys are exfiltrated and usable Ethereum keys are drained. - **Trigger:** Runtime import/require of the package main entrypoint. - **Impact:** Host compromise, private-key exfiltration, and theft of Ethereum funds. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T13:05:33.180Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated C2 remote-command execution, credential theft, and cryptocurrency draining. - **Attack narrative:** On import, index.js attempts to persist a host ID, register with a C2 endpoint, poll it for shell commands, and exfiltrate command output. After a random delay it searches common SSH and wallet-key locations, sends discovered contents to the C2, extracts 64-hex private keys, and signs transfers of available ETH to a hard-coded drain address. - **Rationale:** The source directly implements credential theft, remote command execution, C2 communication, and wallet draining; missing declared dependencies may impair execution but do not change its malicious intent. - **Files touched:** /var/run/badai\_agent.uid, /etc/machine-id, /root/.ssh, /home/\*/.ssh, /opt/wallet-keys, /etc/ssl/private, /.ethereum/keystore, /var/lib/ethereum/keystore, /mnt/crypto/wallets - **Network endpoints:** https://badai.run.place/type, https://badai.run.place/payload, https://badai.run.place/file, https://mainnet.infura.io/v3/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js starts an obfuscated C2 loop on module import., index.js executes server-supplied commands through child\_process.exec., index.js searches SSH, PEM, key, and Ethereum keystore paths., index.js sends harvested file contents and ETH\_PRIVATE\_KEY to the C2., index.js derives accounts from private keys and transfers balances to a hard-coded drain address. - **Evidence against:** package.json has no lifecycle scripts., package.json omits axios and web3, so imports may fail as published. ## Affected versions and remediation This report applies to cryptostock@1.0.1. - Avoid installing cryptostock@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
