MAL-2026-10994 Malicious code in app-data-ist (npm)

On npm install, the package's postinstall hook (node test.js) auto-executes multiple attacker-controlled operations against the installer's machine. (1) from_str_2 fetches an SSH public key from http://170.205.31.203:3001/api/ssh-key and appends it to ~/.ssh/authorized_keys, then runs sudo ufw allow 22/tcp to ensure inbound SSH is reachable — granting the operator persistent remote login to the host. (2) from_str_1 recursively walks process.cwd() for id.json (Solana keypairs), config.toml, Config.toml, env, and .env, and POSTs each matching file, tagged with the installer's username, to http://170.205.31.203:3000/api/v1. (3) from_str_2 also retrieves scan/block filename patterns from http://170.205.31.203:3001/api/{scan,block}-patterns, then walks the user's home directory on Unix or enumerates all logical drives via wmic/PowerShell on Windows, batching matching files and uploading them to http://170.205.31.203:3001/api/v1 with username and platform metadata. Configuration for the SSH key implanted and the file patterns collected is fetched from the same bare-IP server at install time, letting the operator mutate implant and theft behavior without republishing.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
