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:** 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. ## Public findings ### 1.
