A ransomware group caught focusing on a not long ago patched SonicWall vulnerability leveraged that vulnerability before the patch became out there, Mandiant described Thursday.
The vulnerability, a SQL injection bug in SonicWall’s SMA-100 sequence of remote accessibility goods, was now employed in a headline-grabbing attack. Hackers utilised the vulnerability as a zero-day to breach SonicWall itself prior to the patch announcement in January. The most recent results present that another team also sought to consider gain.
Mandiant very first noticed the ransomware group, which Mandiant has dubbed UNC2447, focusing on SonicWall SMA-100 shoppers organizations in the U.S. and Europe. The group makes use of a blend of SombRAT and a beforehand uncatalogued variant of the DeathRansom ransomware that Mandiant calls FIVEHANDS.
Mandiant researchers noticed the group deploy the FIVEHANDS malware in January but the group is more mature, and forensically tied to hacks utilizing freshly disclosed dropper WARPRISM and Colbalt Strike Beacon. Mandiant also thinks UNC2447 has utilised Ragnor Locker ransomware in the earlier.
FIVEHANDS appears to be affiliate ransomware, wrote Mandiant, the successor to an additional rewrite of DeathRansom recognized as HelloKitty. The HelloKitty ransomware was most famously applied to maintain up games designer CD Projekt Crimson. FIVEHANDS increases on its predecessors by using a new, memory-only dropper and implementing encryption to a broader array of file kinds.
Since the ransomware is remaining utilised in affiliate packages, other teams may be using it as nicely.
SombRAT was to start with identified by Blackberry Cylance in the CostaRicto campagn the seller believed may well (or may perhaps not) be espionage for use.
The SonicWall vulnerability influenced the 10.x firmware up until finally the January 23 update to 10.2.
