app-data-istnpm
app-data-ist is a confirmed malicious npm package (MAL-2026-10994) 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 app-data-ist (npm)
What this malware does
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.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for app-data-ist (version 2.1.6). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging app-data-ist across your stack and pipelines.
If you installed it — respond
Remove app-data-ist 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 app-data-ist was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks app-data-ist before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
