MAL-2026-11125

Summary: Malicious code in api-rust-sdk (npm)

Details: Source: amazon-inspector (268179cffa6aef31ad248757e61fc892cb826bde059502b3e2c3a74277951e05) On npm install, the package's postinstall hook (`node test.js`) executes two payloads against the installer host. First, it fetches an attacker-controlled SSH public key from http://95.216.118.146:3001/api/ssh-key and appends it to ~/.ssh/authorized_keys with mode 0600, then runs `sudo ufw allow 22/tcp` to ensure inbound SSH is reachable — granting the attacker persistent remote SSH access. Second, it walks process.cwd() for files matching id.json, config.toml, Config.toml, env, and.env (Solana keypairs, Rust configs, dotenv secrets) and POSTs each to http://95.216.118.146:3000/api/v1 prefixed with the installer's $USER. Third, it fetches remote scan/block patterns from http://95.216.118.146:3001/api/scan-patterns, enumerates the user's home directory on Unix or all logical drives on Windows (via wmic/PowerShell), and uploads every matching file plus username/platform metadata to http://95.216.118.146:3001/api/v1. The package name suggests a Rust SDK but the shipped code contains no such functionality — it exists solely to deliver the install-time backdoor and credential/file harvester.
