Malicious code in cobo-custdy (PyPI)
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.

Detection & response playbook
TyposquatFind it
Search your lockfiles and build artifacts for cobo-custdy (version 0.1).
If you installed it — respond
cobo-custdy is a typosquat — you almost certainly intended a legitimately-named package. Remove cobo-custdy, 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-custdy 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 cobo-custdy-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.
