At the very least half of dozen GitHub accounts from faux researchers involved with a fraudulent cybersecurity organization have been noticed pushing malicious repositories on the code web hosting company.
All 7 repositories, which are nonetheless offered as of writing, declare to be a proof-of-notion (PoC) exploit for purported zero-working day flaws in Discord, Google Chrome, and Microsoft Exchange Server.
VulnCheck, which found the exercise, reported, “the people building these repositories have place important energy into generating them glimpse legitimate by generating a network of accounts and Twitter profiles, pretending to be section of a non-existent organization termed Significant Sierra Cyber Safety.”
The cybersecurity business stated it initial came across the rogue repositories in early May well when they had been observed releasing comparable PoC exploits for zero-working day bugs in Sign and WhatsApp. The repositories internet hosting the two PoCs have considering that been taken down.
Other than sharing some of the purported findings on Twitter in an attempt to make legitimacy, the established of accounts have been observed to use headshots of genuine security researchers from firms like Immediate7, suggesting that the threat actors have gone to good lengths to execute the marketing campaign.
The PoC is a Python script that’s developed to download a malicious binary and execute it on the victim’s functioning process, be it Home windows or Linux.

“The attacker has made a large amount of exertion to create all these faux personas, only to deliver extremely obvious malware,” VulnCheck researcher Jacob Baines said. “It really is unclear if they have been productive, but offered that they have ongoing to go after this avenue of attacks, it would seem they believe that they will be effective.”
It is at this time not known if this is the operate of an amateur actor or an sophisticated persistent danger (APT). But stability researchers have beforehand appear less than the radar of North Korean country-state groups, as unveiled by Google in January 2021.
If anything, the results clearly show the need for training caution when it will come to downloading code from open up resource repositories. It can be also essential that end users scrutinize the code prior to execution to make sure they will not pose any stability dangers.
