Kaseya denies ransomware payment because it hails ‘100% effective’decryption tool
Kaseya has denied rumors that it paid a ransom to the REvil cybercrime gang since it continues to roll out a decryptor to victims of a current ransomware attack.
The application supply chain attack, which began on July 2, is believed to have affected as much as 1,500 organizations via the hack of IT management platform Kaseya VSA.
Kaseya revealed on July 22 that it had obtained a decryption tool from the “third party” and was trying to restore the environments of impacted organizations with assistance from anti-malware experts Emsisoft.
The update sparked speculation regarding identity of the unnamed third party, with Allan Liska of Recorded Future’s CSIRT team positing a disgruntled REvil affiliate, the Russian government, or that Kaseya themselves had paid the ransom.
The theory that the universal decryptor key became available as a result of police action was strengthened on July 13 when the dark web domains related to REvil abruptly went offline.
However, some experts also said it absolutely was likely that this is a prelude to REvil, whose other notable scalps include Travelex and meat supplier JBS, rebranding itself in a bid to dodge law enforcement.
The cybercrime outfit was believed to own initially demanded a payment of $70 million from Kaseya, before lowering the selling price to $50 million.
Kaseya, which includes reportedly granted organizations access to the decryptor contingent on signing a non-disclosure agreement, addressed rumors that it had paid a ransom in a statement yesterday (July 26):
Recent reports have suggested that our continued silence on whether Kaseya paid the ransom may encourage additional ransomware attacks, world market onion – https://c418wiki.absolutelywhizzer.co.uk/index.php?title=User:LetaJensen6997 but nothing might be further from our goal. While each company must make its decision on whether to pay for the ransom, Kaseya decided after consultation with experts never to negotiate with the criminals who perpetrated this attack and we’ve not wavered from that commitment. Therefore, we are confirming in no uncertain terms that Kaseya did not pay a ransom – either directly or indirectly through an alternative party – to acquire the decryptor.
Kaseya said that “the decryption tool has proven 100% able to decrypting files which were fully encrypted in the attack&rdquo ;.
It added: “We continue to offer the decryptor to customers that request it, and we encourage all our customers whose data may have been encrypted throughout the attack to reach out to your contacts at Kaseya&rdquo ;.
Last week, meanwhile, security researchers from the organization that unearthed the zero-day Kaseya vulnerabilities exploited by REvil disclosed a trio of additional zero-day flaws in another Kaseya product.
The Dutch Institute for Vulnerability Disclosure (DIVD) advised users of cloud-based Kaseya Unitrends, which is available as an add-on for Kaseya VSA, to not expose the service to the internet until a patch was released.
Also last week, Huntress Labs released a post speculating on why the compromise of 60 upstream, managed company customers via a fake software update hadn’t had a lot more calamitous consequences.
Dismissing the proven fact that Kaseya’s system shutdown was the primary reason, security researcher John Hammond pondered, among other potential reasons, whether threat actors had learned “from previous incidents (like Colonial Pipeline) that a much bigger impact might invite government intervention?”
