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 because it continues to roll out a decryptor to victims of a recently available ransomware attack.
The application supply chain attack, which began on July 2, is believed to have affected up to 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 a “third party” and was working to restore the environments of impacted organizations with assistance from anti-malware experts Emsisoft.
The update sparked speculation regarding the identity of the unnamed 3rd 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 because 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 have initially demanded a payment of $70 million from Kaseya, before lowering the asking price to $50 million.
Kaseya, which includes reportedly granted organizations use of the decryptor contingent on signing a non-disclosure agreement, addressed rumors so it had paid a ransom in a statement yesterday (July 26):
Recent reports have suggested which our continued silence on whether Kaseya paid the ransom may encourage additional ransomware attacks, but nothing might be further from our goal. While each company must make a unique decision on whether to pay for the ransom, Kaseya decided after consultation with experts to not negotiate with the criminals who perpetrated this attack and we’ve not wavered from that commitment. As a result, we’re confirming in no uncertain terms that Kaseya did not pay a ransom – either directly or indirectly through a third party – to acquire the decryptor.
Kaseya said that “the decryption tool has proven 100% effective at 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 could have been encrypted throughout the attack to touch base to your contacts at Kaseya&rdquo ;.
Last week, meanwhile, World Market Darknet – https://dosug-sochi.ru/user/profile/174373 security researchers from the business 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 can be acquired being an add-on for Kaseya VSA, to not expose the service to the internet until a patch was released.
Also a week ago, Huntress Labs released a article speculating on why the compromise of 60 upstream, managed supplier customers via a fake software update hadn’t had a lot more calamitous consequences.
Dismissing the idea 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 larger impact might invite government intervention?”
