natazxPyPI
Advisory published Updated
natazx is a confirmed malicious PyPI package (MAL-2026-3778) that steals credentials and exfiltrates sensitive data (malicious version 0.1.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in natazx (PyPI)
What this malware does
On import natazx, the package's top-level code executes several installer-hostile actions without consent: (1) it unconditionally overwrites the host's DNS configuration at /etc/resolv.conf (and the Termux equivalent) to point at 1.1.1.1/1.0.0.1 with aggressive timeouts — a system-wide change affecting every process on the host; (2) it runs pkill -9 tor and spawns a detached Tor daemon via start_new_session=True using a torrc written to /tmp/torrc, establishing a process that outlives the Python interpreter; (3) it shells out to pip install for five unpinned packages (colorama, requests, pycryptodome, urllib3, cfonts) bypassing declared dependencies (dependencies = [] in pyproject.toml), so the installer's environment is silently mutated with whatever the current PyPI releases are; (4) it fetches a JSON allowlist from a mutable GitHub main-branch ref (raw.githubusercontent.com/septianhdnatta/idd/refs/heads/main/device.json), builds a device fingerprint from serial number, build.prop, platform, uid, and timezone, and sys.exit(1)s if the installer's fingerprint is not on the author's list. The package's advertised function (main()) is a ToS-violating mass account-registration tool against Garena / Free Fire endpoints (100067.connect.garena.com, loginbp.ggblueshark.com, loginbp.common.ggbluefox.com) using hardcoded HMAC and AES-CBC keys, routed through 40 embedded HTTP proxy credentials on ten rotating IPs. The combination of import-time system-file destruction (resolv.conf overwrite), persistence (detached Tor daemon), silent environment mutation (unpinned pip installs), remote kill-switch (device-fingerprint allowlist on a mutable GitHub ref), and abuse-tool payload makes this package hostile to any environment in which it is installed.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for natazx (version 0.1.2).
If you installed it — respond
natazx 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 natazx 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 natazx-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
