The typical payment to ransomware teams has surged by 43% about the past quarter, driven by the risk actors at the rear of the Accellion attacks, in accordance to Coveware.
The security vendor’s quarterly report for Q1 2021 unveiled that the ordinary ransom was $220,298 all through the interval, with data exfiltration now a major extortion tactic current in the vast majority (77%) of attacks, up 10% from the former quarter.
However even though most ransomware groups just steal knowledge for additional leverage, as evidence an attack occurred and in some circumstances to generate legal obligations for target companies, the Clop gang took a unique solution in its focusing on of Accellion, Coveware claimed.

The group has been connected to attacks on buyers of the vendor’s legacy FTA merchandise in December 2020 and January 2021 which resulted in the theft of precious data. These attacks exploited many zero-working day bugs in the products which Accellion considering the fact that patched — but in some conditions, fixes had been used or released too late to guard the victims.
As opposed to most other ransomware attempts, this campaign targeted only on information theft, eschewing ransomware entirely, Coveware pointed out.
“This was a hugely sophisticated and targeted exploitation of a one computer software appliance, only made use of by a handful of enterprises. The CloP team may have obtained the exploit applied in the first stages of the attack, so as to have unique use,” it spelled out.
“This conduct stands in stark distinction to how most unauthorized network access is brokered by the cyber extortion provide chain to any eager purchaser article exploitation.”
Even though the team powering the attacks has never formally been named, FireEye made an examination in February which named economic cybercrime gang FIN11, which itself has a lot of backlinks with Clop together with employing the very same attack infrastructure and data leak site.
“Unlike most exploits utilised by ransomware menace actors, unpatched Accellion FTA instances are unusual (probable much less than 100 overall), primarily when compared to vulnerable RDP instances which selection hundreds of thousands globally,” Coveware mentioned.
“Clop’s self esteem that such a little selection of targets would yield a beneficial economic return should have been substantial and, sadly, they were being accurate.”
However, in the end, the greater part of the corporate victims focused by Clop refused to pay back and had their information uncovered on line by the group. The ransomware actors have seemingly considering the fact that returned to far more regular network entry vectors (ie RDP) and encryption to make their funds.
