Malicious code in pretty-tabulate (PyPI)
Details
-= Per source details. Do not edit below this line.=-
Source: kam193 (807e99c43a51fb7620cee47a356774c3ead94e75c4bc48621a942c835107b2eb)
Malicious code hidden in the color-list package uses the presence of pretty-tabulate as a trigger to load code hidden in likely a third malicious package. Packages were published simultaneously by two accounts not used for about a year, suggesting hijacked access.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2026-03-color-list
Reasons (based on the campaign):
-
The malicious code is intentionally included in a dependency of the package
-
obfuscation
