Kaseya denies ransomware payment because it hails ‘100% effective’decryption tool
Kaseya has denied rumors so it paid a ransom to the REvil cybercrime gang because it continues to roll out a decryptor to victims of a current ransomware attack.
The software 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 so it had obtained a decryption tool from the “third party” and was working to restore the environments of impacted organizations with the aid of anti-malware experts Emsisoft.
The update sparked speculation regarding the 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 because of police action was strengthened on July 13 once the dark web domains related to REvil abruptly went offline.
However, some experts also said it was likely that this was 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 has reportedly granted organizations use of the decryptor contingent on signing a non-disclosure agreement, addressed rumors so it had paid a ransom in a record yesterday (July 26):
Recent reports have suggested that 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 the ransom, Kaseya decided after consultation with experts to not negotiate with the criminals who perpetrated this attack and we have not wavered from that commitment. As a result, we’re confirming in no uncertain terms that Kaseya didn’t pay a ransom – either directly or indirectly through a 3rd party – to acquire the decryptor.
Kaseya said that “the decryption tool has proven 100% effective at decrypting files that were fully encrypted in the attack&rdquo ;.
It added: “We continue to supply the decryptor to customers that request it, and we encourage all our customers whose data might have been encrypted during the attack to reach out to your contacts at Kaseya&rdquo ;.
Last week, meanwhile, security researchers from the corporation 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, World Market Darknet – http://www2u.biglobe.ne.jp/~k_yone/cgi-bin/g_book/g_book.cgi/summary/g_book.cgi never to expose the service to the net until a patch was released.
Also last week, Huntress Labs released a blog post speculating on why the compromise of 60 upstream, managed service provider customers using a fake software update hadn’t had even 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 bigger impact might invite government intervention?”
