Hackers poison source code for largest Discord bot platform

The Top.gg Discord bot community with over 170,000 members has been impacted by a supply-chain attack aiming to deliver malware that steals sensitive information. The threat actor has been using several tactics, techniques, and procedures (TTPs) over the years including hijacking GitHub accounts, distributing malicious Python packages, using a fake Python infrastructure, and social engineering.

Checkmarx researchers discovered the campaign and note that the main goal was most likely data theft and monetization through selling the stolen info. According to the researchers, the attacker's activity started back in November 2022, when they first uploaded malicious packages on the Python Package Index (PyPI). In the years that followed, more packages carrying malware were uploaded to PyPI. These resembled popular open-source tools with enticing descriptions that would make them more likely to rank well in search engine results. The most recent upload was a package named "yocolor" in March this year. In early 2024, the attackers set up a fake Python package mirror at "files[.]pypihosted[.]org," which is a typosquatting attempt to mimic the authentic "files.pythonhosted.org" where the artifact files of PyPI packages are stored. This fake mirror was used to host poi...
