Beware: 3 Malicious PyPI Packages Found Targeting Linux with Crypto Miners

3 new destructive offers have been discovered in the Python Offer Index (PyPI) open up-resource repository with capabilities to deploy a cryptocurrency miner on impacted Linux devices.

The a few dangerous deals, named modularseven, driftme, and catme, captivated a whole of 431 downloads around the past thirty day period in advance of they were taken down.

“These deals, upon original use, deploy a CoinMiner executable on Linux units,” Fortinet FortiGuard Labs researcher Gabby Xiong explained, including the marketing campaign shares overlaps with a prior marketing campaign that included the use of a deal identified as culturestreak to deploy a crypto miner.

The malicious code resides in the __init__.py file, which decodes and retrieves the first phase from a distant server, a shell script (“unmi.sh”) that fetches a configuration file for the mining activity as nicely as the CoinMiner file hosted on GitLab.

The ELF binary file is then executed in the qualifications applying the nohup command, therefore ensuring that the procedure continues to run right after exiting the session.

“Echoing the approach of the before ‘culturestreak’ package, these offers conceal their payload, effectively minimizing the detectability of their malicious code by hosting it on a remote URL,” Xiong said. “The payload is then incrementally produced in numerous phases to execute its malicious actions.”

The connections to the culturestreak offer also stems from the point that the configuration file is hosted on the area papiculo[.]net and the coin mining executables are hosted on a general public GitLab repository.

A single noteworthy enhancement in the a few new offers is the introduction of an further phase by concealing their nefarious intent in the shell script, therefore aiding it evade detection by security software and lengthening the exploitation procedure.

“Also, this malware inserts the destructive instructions into the ~/.bashrc file,” Xiong stated. “This addition guarantees the malware’s persistence and reactivation on the user’s device, properly extending the duration of its covert procedure. This approach aids in the extended, stealthy exploitation of the user’s machine for the attacker’s reward.”
