On our Daily Diaries #297 and #298, we covered Sodinokibi (a.k.a. REvil) supply-chain attack on Kaseya systems, where the group managed to infect a lot of customers of Kaseya On-premises VSA appliances. On their deep-website Sodinokibi was offering their decryptor
for $45k USD for each victim (or $70 million USD for a universal decryptor). It seems that a few victims payed the individual decryptor, but since last week all deep web sites controlled by Sodinokibi went dark.
<div><br>
</div>
<div>Reportedly the group went offline on July 13th, almost a week ago, and so far there is no sign of recovery. It's not uncommon for deep-web websites to go offline for a few days. Specially in cases where the gang gets a lot of attention quickly, they shutdown
parts of its structure to change servers and make tracking harder. What is uncommon in Sodinokibi's case is all of its structure becoming offline at once, when they are still "profiting" from a major attack like Kaseya. Our team monitors REvil "Happy Blog",
having lastly detected a new post on July 11th. Some companies that decided to pay the ransom are complaining about the lack of "support", as in some cases the bought decryptor only worked for a few files. This can happen if some of the files are encrypted
with a different key.</div>
<div><br>
</div>
We would like to take this opportunity to reinforce to companies to never pay the ransom. This incident shows that paying the ransom is no guarantee of having your files back. Besides, it gives the attackers resources to finance new attacks, and motivation
to develop and implement new techniques in their malware, increasing the damage and number of victims.
