The Raspberry Robin cyber-worm operation has contaminated almost 3,000 units in virtually 1,000 organizations within the final 30 days, in keeping with Microsoft telemetry — and the menace appears to be molting into one thing new.
Raspberry Robin was initially noticed again in May, infecting targets through contaminated USB drives and worming to different endpoints — however then remaining dormant. That modified in July, when Microsoft safety researchers noticed Raspberry Robin importing the FakeUpdates malware to units the place it was nesting. Further exploration of the exercise revealed some infrastructure overlaps with the notorious Dridex Trojan and the Evil Corp (aka DEV-0243) ransomware gang.
Since then, Raspberry Robin has additionally began deploying IcedID, Bumblebee, and Truebot, in keeping with a Microsoft replace on Oct. 27, with researchers uncovering a notable spate of assaults in October which have resulted in Clop ransomware infections. The menace has additionally taken flight past its preliminary USB entry vector, researchers famous, and is now able to utilizing at the least 4 completely different strategies for gaining buy on units.
The computing big attributes the post-compromise Clop exercise to a gaggle it tracks as DEV-0950 — aka FIN11 or TA505 — indicating that Raspberry Robin is establishing itself iin the broader cybercrime economic system.
“DEV-0950 historically makes use of phishing to amass nearly all of their victims, so this notable shift to utilizing Raspberry Robin allows them to ship payloads to current infections and transfer their campaigns extra rapidly to ransomware phases,” Microsoft researchers famous.
They added, “Given the interconnected nature of the cybercriminal economic system, it is attainable that the actors behind these Raspberry Robin-related malware campaigns — often distributed by different means like malicious adverts or e-mail — are paying the Raspberry Robin operators for malware installs.”
