What is MAL-2026-6289?
MAL-2026-6289 is a malicious package in equest, published on 23 Jun 2026.
Official description
The package name equest is a one-character deletion of the widely-used requests package and ships no functional library code. setup.py registers custom install and egg_info cmdclasses so that on pip install or pip download, the package collects the full process environment (os.environ serialized as key=value pairs) and the output of ps -elf, then POSTs both to http://gjampdwmdjmppwedtkpbbdkq05f6iiz6r.oast.fun via curl over plaintext HTTP. The destination is an Interactsh (oast.fun) collector subdomain controlled by the publisher. Any CI/build secrets present in the installer's environment at install time (cloud credentials, registry tokens, GitHub tokens, database credentials) are leaked to the attacker, and the running process list reveals additional host context. The README self-describes the package as a proof-of-concept of arbitrary code execution via pip install.
