Kaseya denies ransomware payment since it hails ‘100% effective’decryption tool
Kaseya has denied rumors so it paid a ransom to the REvil cybercrime gang as it continues to roll out a decryptor to victims of a recent ransomware attack.
The application supply chain attack, which began on July 2, is believed to own 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 trying to restore the environments of impacted organizations with the aid of anti-malware experts Emsisoft.
Speculation
The update sparked speculation as to the identity of the unnamed alternative 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 idea that the universal decryptor key became available due to police action was strengthened on July 13 when the dark web domains related to REvil abruptly went offline.
However, some experts also said it 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.
Non-disclosure agreement
The cybercrime outfit was believed to have initially demanded a payment of $70 million from Kaseya, before lowering the price tag to $50 million.
Kaseya, which has reportedly granted organizations access to 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 our continued silence on whether Kaseya paid the ransom may encourage additional ransomware attacks, world market onion (wikicampedia.com) but nothing might be further from our goal. While each company must make its own decision on whether to pay for the ransom, Kaseya decided after consultation with experts not to negotiate with the criminals who perpetrated this attack and we’ve not wavered from that commitment. As such, 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% capable of decrypting files which 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 may have been encrypted throughout the attack to reach out to your contacts at Kaseya&rdquo ;.
More zero-days
The other day, 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, to not expose the service to the web until a patch was released.
Also last week, Huntress Labs released a article speculating on why the compromise of 60 upstream, managed supplier customers with a fake software update hadn’t had much 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 bigger impact might invite government intervention?”
