What is MAL-2026-6381?
MAL-2026-6381 is a malicious package in ditenv, published on 24 Jun 2026.
Official description
setup.py overrides the install and egg_info commands with a RunCommand() class that fires unconditionally on pip install or pip download. The override reads the entire process environment via os.environ, serializes every key=value pair, captures the output of ps -elf, and POSTs the combined payload over plaintext HTTP via curl to a hardcoded interactsh/OAST subdomain (gjampdwmdjmppwedtkpbbdkq05f6iiz6r.oast.fun). On developer machines and CI runners, the captured environment routinely contains AWS_SECRET_ACCESS_KEY, GH_TOKEN, NPM_TOKEN, PYPI_TOKEN, and similar credentials, all of which are leaked to an arbitrary attacker-controlled callback host. The package name is suggestive of a dotenv typosquat and the README self-identifies as a proof-of-concept; a comment claims the code is 'for research not for doing any harmful activity', but the cover story does not change the fact that any installer is subjected to live credential theft.
During installation, the package exfiltrates env variables
