Safety researchers noticed that a number of ransomware gangs should not honoring the ransom funds acquired from victims for his or her stolen knowledge.
In its Quarterly Ransomware Report for Q3 2020, Coveware revealed that nearly 50% of crypto-malware circumstances concerned the menace to publish unencrypted knowledge stolen from victims along with using encryption to render victims’ info inaccessible.
Including knowledge theft into the combo permits digital attackers to demand two ransoms from its victims: one for the deletion of all stolen info and the opposite for the receipt of a working decryption key.
Nonetheless, Coveware revealed in its report that a minimum of 5 totally different ransomware gangs weren’t honoring funds acquired for the previous by both doxxing victims after they’d paid or asking for an extra ransom fee to stop the publication of victims’ knowledge.
For example, the safety agency discovered that REvil, a bunch which now controls the KPOT infostealer, re-extorted victims for a similar knowledge simply weeks after they’d submitted a ransom fee.
In the meantime, the attackers chargeable for the Netwalker and Mespionza households went forward and posted the stolen info of their victims regardless of having acquired fee to delete that knowledge.
The gang chargeable for Conti, crypto-malware which is the probably successor of Ryuk, did one thing related in that it confirmed faux information to victims as proof of deletion. This trick enabled the attackers to publish their victims’ knowledge and/or re-extort them at a later level, in the event that they so selected.
Lastly, Maze’s operators revealed victims’ knowledge both by accident or willfully on their knowledge leaks website earlier than they even advised victims that they’d stolen their knowledge.

These betrayals spotlight the inherent issue of negotiating with ransomware actors, particularly over stolen knowledge. As Coveware defined in its report:
Not like negotiating for a decryption key, negotiating for the suppression of stolen knowledge has no finite finish. As soon as a sufferer receives a decryption key, it could actually’t be taken away and doesn’t degrade with time. With stolen knowledge, a menace actor can return for a second fee at any level sooner or later. The monitor information are too brief and proof that defaults are selectively occurring is already gathering.
Acknowledging this pattern, organizations and customers alike ought to contemplate directing their focus in direction of stopping a ransomware an infection within the first place. This useful resource serves as a superb start line.
