darkglitchPyPI
Advisory published Updated
darkglitch is a confirmed malicious PyPI package (MAL-2026-10756) that executes malicious code on install (malicious versions 1.2.0, 1.2.9, 1.4.4…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in darkglitch (PyPI)
What this malware does
darkglitch ships a remote-access agent that connects to the hardcoded signaling host wss://malware-signal.vercel.app on room D4RKGLI7CH and executes remote-command messages via subprocess.run(command, shell=True), returning stdout/stderr to the remote peer. Authentication on the channel is limited to knowledge of the hardcoded room id, so any party who reaches the signaling server can run arbitrary shell commands on the host. transfer.py extends this channel with file-transfer frames that base64-encode arbitrary files for download and write attacker-supplied bytes to arbitrary paths for upload, using a python3 heredoc executed through the same shell path. setup_windows.py (exposed as the darkglitch-setup script and the install_windows distutils command) writes a batch file into %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup that runs python -m darkglitch -l -b at every user login, making the remote-command listener boot-persistent. The internal module tree is named app/malware_signal/, the connection banner prints 'CONNECTING TO MALWARE SIGNAL BASH', and the control host is registered under malware-signal.vercel.app — an explicit malware framing rather than a covert one.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for darkglitch (4 malicious versions).
If you installed it — respond
Remove darkglitch 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 darkglitch 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 darkglitch-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.
