Which versions of cobo-python are malicious?

The following PyPI versions of cobo-python are flagged malicious: 0.1. Treat any of these as compromised.

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

cobo-python is a typosquat — you almost certainly intended a legitimately-named package. Remove cobo-python, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

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

If cobo-python 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 cobo-python part of a known attack campaign?

Yes — cobo-python is associated with the 2024-08-old-cobo-sectest 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 cobo-python 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 cobo-python (version 0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging cobo-python across your stack and pipelines.

Immediate action

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

pip uninstall cobo-python

What this malware does

It appears to be a forgotten pentest checking typosquatting against cobo-custody package, but may also have malicious purposes. During installation, if a machine is Mac, an obfuscated code attempts to download and execute a shell script. Currently, the server does not respond.

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: 2024-08-old-cobo-sectest

Reasons (based on the campaign):

Downloads and executes a remote executable.
clones-real-package
crypto-related
The package overrides the install command in setup.py to execute malicious code during installation.
obfuscation
typosquatting

Typosquat

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for cobo-python (version 0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging cobo-python across your stack and pipelines.
If you installed it — respond
cobo-python is a typosquat — you almost certainly intended a legitimately-named package. Remove cobo-python, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If cobo-python 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 cobo-python 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

Detect & block this

O3 blocks cobo-python-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.
