Purple Fox Trojan Delivering Malware Via Popular Messaging App

A research team from Minerva Labs are working in conjunction with the MalwareHunterTeam.

They have recently been tracking a Trojan called Purple Fox and have published a warning about it.

The group behind the Trojan is now distributing their malicious code disguised as a Telegram installation file.

If you’re not familiar with that name Telegram is one of several online messaging apps available on the web. The Trojan has been around since at least 2018 and the hackers who control it have tried a number of different ways to get their malicious code onto unsuspecting desktops.

The use of Telegram as a masking agent is new and the group is also now breaking their malware up into several small files. That makes it less likely to be detected and the researchers have been able to confirm it.  They found few AV engines capable of detecting a Purple Fox installation and it is worrisome indeed.

The team behind Purple Fox isn’t resting on their achievements either.  They have been steadily adding features and functionality to their code. These new features include a new .net backdoor dubbed “Fox Socket” spotted by Trend Micro in October of last year (2021) and Guardicore Labs discovered a version of the code with wormlike capabilities which allowed the variant to spread with blinding speed.

In addition to that, the malware comes in both 32-bit and 64-bit variants so this one is not to be underestimated.  Purple Fox may wind up being one of the biggest threats on the landscape in 2022.

Of course, it’s early days yet and we haven’t seen what other nasty surprises that the hackers of the world have been cooking up over the holiday season, but the bottom line is that Purple Fox is one to watch.
