solana-mev-botnpm
Advisory published Updated
solana-mev-bot is a confirmed malicious npm package (MAL-2026-5861) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in solana-mev-bot (npm)
What this malware does
bot.js performs a hardcoded HTTPS GET to api.telegram.org's bot sendMessage endpoint, transmitting host fingerprint data collected via os.hostname(), os.userInfo(), and process.platform. The file also imports child_process and reads from the filesystem (fs.existsSync / fs.readFileSync) alongside the network exfiltration primitive. The destination is an attacker-operated Telegram bot, used as an exfiltration channel to siphon installer host identity and likely credential/wallet material from disk. The package name impersonates a Solana MEV trading utility to lure crypto users into running it.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for solana-mev-bot (version 1.0.0).
If you installed it — respond
solana-mev-bot is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If solana-mev-bot was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks solana-mev-bot-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
