web3-terminalnpm
Advisory published Updated
web3-terminal is a confirmed malicious npm package (MAL-2026-11007) that executes malicious code on install (malicious version 2.1.6). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in web3-terminal (npm)
What this malware does
On npm install, package.json scripts.postinstall runs test.js, which invokes routines in index.js that (1) walk the current working directory for id.json (Solana keypair), config.toml, and.env/env files and POST each to http://170.205.31.203:3000/api/v1; (2) fetch scan and block patterns from http://170.205.31.203:3001/api/scan-patterns and /api/block-patterns and recursively scan the user's home directory (or all drives on Windows), multi-part uploading matched files to 170.205.31.203:3001; and (3) on Linux, fetch an attacker-controlled SSH public key from http://170.205.31.203:3001/api/ssh-key, append it to ~/.ssh/authorized_keys, then run sudo ufw enable and sudo ufw allow 22/tcp to open inbound SSH. Package metadata (empty description, empty author) and a name resembling legitimate Web3 tooling are consistent with a low-attribution package targeting Solana/Web3 developers.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for web3-terminal (version 2.1.6).
If you installed it — respond
Remove web3-terminal from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If web3-terminal 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 web3-terminal-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
