    Summary: Malicious code in kotlin-stdlib-jdk8 (PyPI)

    Details: Source: kam193 (f217cf2fd34c9cab642b70bd9d778e6ef08a3dfba1954060a29983f2d3e6d47e) Importing the module triggers sending out the hostname to the package author. It looks to be a placeholder/pentest activity related to BytedDance. 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: 2024-11-0wn-sh Reasons (based on the campaign): - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
