The Raspberry Robin malware is getting used to ship all types of damaging code, together with ransomware, to compromised endpoints (opens in new tab), Microsoft has warned.

It appears the malware, first found late in 2021, and whose endgame was unknown on the time, remodeled into an an infection service obtainable to anybody with money to pay. 

Cybersecurity researchers from Microsoft have printed an in depth weblog publish (opens in new tab) by which they describe Raspberry Robin as “a part of a fancy and interconnected malware ecosystem”, with hyperlinks to different malware households and alternate an infection strategies. 

An infection for rent

Whoever is behind Raspberry Robin stored busy over these final couple of weeks, as in response to Microsoft Defender for Endpoint knowledge, virtually 3,000 units in 1,000 organizations have skilled at the least one Raspberry Robin payload-related alert within the final 30 days. 

Payloads differ, the corporate additional defined, from FakeUpdates malware which led to doable EvilCorp exercise, to IceID, Bumblebee, and Truebot. That is all July 2022. 

In October 2022, although, Microsoft additionally noticed Raspberry Robin being utilized by FIN11 (AKA TA505, – the group behind the Dridex banking trojan and Locky ransomware). This exercise led to Cobalt Strike hands-on-keyboard compromises, the corporate defined, generally with a Truebot an infection in between the Raspberry Robin and Cobalt Strike phases. Following the Cobalt Strike beacon, the group deployed the Clop ransomware. 

All issues thought of, Microsoft concluded that the group behind Raspberry Robin is taking funds to deploy numerous malware and ransomware to its victims’ endpoints.

“Given the interconnected nature of the cybercriminal financial system, it’s doable that the actors behind these Raspberry Robin-related malware campaigns—normally distributed by way of different means like malicious adverts or electronic mail—are paying the Raspberry Robin operators for malware installs,” the report concludes.

Raspberry Robin was first recognized when researchers from Purple Canary found a “cluster of malicious exercise”. The malware is normally distributed offline, by way of contaminated USB drives. After analyzing an contaminated thumb drive, the researchers found that the worm spreads to new units by way of a malicious .LNK file.
