Python Developers were targeted by Hackers via Fake “Crytic-Compilers Package” on PyPl
A malicious Python package that was posted to the Python Package Index (PyPI) repository to deliver the information stealer Lumma (also known as LummaC2) has been found by cybersecurity researchers.
The package in question is called crytic-compilers, which is a misspelling of the actual crytic-compile library. The malicious package was downloaded 441 times before being removed by PyPI maintainers.

| “The counterfeit library is interesting in that, in addition [to] being named after the legitimate Python utility, ‘crytic-compile,’ it aligns its version numbers with the real library.”
“Whereas the real library’s latest version stops at 0.3.7, the counterfeit ‘crytic-compilers’ version picks up right here, and ends at 0.3.11 — giving off the impression that this is a newer version of the component.” The discovery “demonstrates seasoned threat actors now targeting Python developers and abusing open-source registries like PyPI as a distribution channel for their potent data theft arsenal.” |
In an additional effort to maintain the deception, it was discovered that some versions of crytic-compilers (such as 0.3.9) installed the package by altering the setup.py script.
But the most recent version eliminates all semblance of a benign library by first detecting whether Windows is the operating system and then launching an application (“s.exe”) that is intended to retrieve more payloads, which includes the Lumma Stealer.
Lumma is a malware-as-a-service (MaaS) information thief that is accessible to other criminal actors. It has been spread using a variety of techniques, including trojanized software, malvertising, and even phony browser upgrades.
Hundreds of WordPress websites are the target of fake browser update campaigns.
The development coincides with Sucuri’s disclosure that over 300 WordPress websites have been infiltrated by malicious Google Chrome update pop-ups that drive users to fraudulent MSIX installers, which in turn trigger the deployment of remote access trojans and information stealers.
In attack chains, the code that causes the phony browser update pop-ups to appear is uploaded by the threat actors after they have gained unauthorized access to the WordPress admin panel and installed the Hustle – Email Marketing, Lead Generation, Options, Popups WordPress plugin.

| “This campaign underscores a growing trend among hackers to leverage legitimate plugins for malicious purposes. By doing so, they can evade detection by file scanners, as most plugins store their data within the WordPress database.” |
