Which versions of python-datetil are malicious?

The following PyPI versions of python-datetil are flagged malicious: 1.1.0, 1.1.2. Treat any of these as compromised.

How do I remediate python-datetil if I installed it?

python-datetil 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.

I already installed python-datetil — how do I know if it already compromised me?

If python-datetil 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.

Is python-datetil part of a known attack campaign?

Yes — python-datetil is associated with the RLMA-2025-04805, 2025-08-python-dateitil, RLUA-2026-00657 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find python-datetil across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for python-datetil (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging python-datetil across your stack and pipelines.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

pip uninstall python-datetil

What this malware does

Package consist of a revshell only. The effective danger is low as it's clearly designed to connect to a localhost only and be used as awareness.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Campaign: 2025-08-python-dateitil

Reasons (based on the campaign):

typosquatting
The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.

Detection & response playbook

Backdoor / remote access

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for python-datetil (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging python-datetil across your stack and pipelines.
If you installed it — respond
python-datetil 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 python-datetil 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 python-datetil 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.

Frequently asked questions

No. python-datetil on PyPI has been identified as a malicious package (versions 1.1.0, 1.1.2 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks python-datetil-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
