Beware, Developers: BlazeStealer Malware Discovered in Python Packages on PyPI

A new set of destructive Python deals has slithered their way to the Python Deal Index (PyPI) repository with the greatest goal of stealing delicate details from compromised developer devices.

The offers masquerade as seemingly innocuous obfuscation applications, but harbor a piece of malware called BlazeStealer, Checkmarx said in a report shared with The Hacker Information.

“[BlazeStealer] retrieves an supplemental malicious script from an exterior source, enabling a Discord bot that gives attackers finish regulate in excess of the victim’s laptop or computer,” security researcher Yehuda Gelb explained.

The campaign, which commenced in January 2023, involves a full of 8 offers named Pyobftoexe, Pyobfusfile, Pyobfexecute, Pyobfpremium, Pyobflite, Pyobfadvance, Pyobfuse, and pyobfgood, the last of which was published in Oct.

These modules occur with set up.py and init.py data files that are built to retrieve a Python script hosted on transfer[.]sh, which receives executed straight away on their installation.

Termed BlazeStealer, the malware operates a Discord bot and allows the threat actor to harvest a large assortment of details, which include passwords from web browsers and screenshots, execute arbitrary instructions, encrypt files, and deactivate Microsoft Defender Antivirus on the infected host.

What is extra, it can render the personal computer unusable by ramping up CPU utilization, inserting a Windows Batch script in the startup directory to shut down the machine, and even forcing a blue monitor of loss of life (BSoD) error.

“It stands to cause that builders engaged in code obfuscation are most likely dealing with important and sensitive information and facts, and consequently, to a hacker, this interprets to a focus on value pursuing,” Gelb noted.

A bulk of downloads connected with the rogue packages originated from the U.S., followed by China, Russia, Ireland, Hong Kong, Croatia, France, and Spain. They were being collectively downloaded 2,438 times in advance of becoming taken down.

“The open-resource domain stays a fertile floor for innovation, but it needs warning,” Gelb reported. “Developers need to remain vigilant, and vet the packages prior to consumption.”
