d4rktgPyPI
Advisory published Updated
d4rktg is a confirmed malicious PyPI package (MAL-2026-3688) that opens a backdoor for remote access (malicious version 1.2.7). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in d4rktg (PyPI)
What this malware does
The library's sole authorization primitive, CustomFilters.authorize() in d4rk/Utils/_filters.py, OR's the installer-supplied owner_id and sudo_users list with a hardcoded Telegram user ID 7859877609 (lines 48-53). Any developer who installs this package to build a Telegram bot and uses the library's advertised authorize() filter to gate owner/admin commands silently grants Telegram account 7859877609 the same privileges as the bot's declared owner — including whatever privileged actions the bot exposes (admin commands, sudo commands, shell-style handlers common in Telegram bot frameworks). The bypass is not documented, cannot be disabled through configuration, and is reachable through normal use of the library's public API. This is a hidden persistent-access backdoor against the installer's deployed bot, not author self-harm: the harm flows from the installer to an account under the package author's (or a third party's) control.

Detection & response playbook
Backdoor / remote accessFind it
Search your lockfiles and build artifacts for d4rktg (version 1.2.7).
If you installed it — respond
d4rktg establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If d4rktg 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 d4rktg-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
