On November 7, 2023, the profilic ransomware group AlphV (a/k/a “BlackCat”) reportedly breached software company MeridianLink’s information systems, exfiltrated data and demanded payment in exchange for not publicly releasing the stolen data. While this type of cybersecurity incident has become increasingly common, the threat actor’s next move was less predictable. AlphV filed a whistleblower tip with the U.S. Securities and Exchange Commission (the “SEC”) against its victim for failing to publicly disclose the cybersecurity incident. AlphV wrote in its complaint[1]:
We want to bring to your attention a concerning issue regarding MeridianLink’s compliance with the recently adopted cybersecurity incident disclosure rules. It has come to our attention that MeridianLink, in light of a significant breach compromising customer data and operational information, has failed to file the requisite disclosure under Item 1.05 of Form 8-K within the stipulated four business days, as mandated by the new SEC rules.
As we have previously reported, the SEC adopted final rules mandating disclosure of cybersecurity risk, strategy and governance, as well as material cybersecurity incidents. This includes new Item 1.05 of Form 8-K, which, beginning December 18, will require registrants to disclose certain information about a material cybersecurity incident within four business days of determining that a cybersecurity incident it has experienced is material. Though AlphV jumped the gun on the applicability of new Item 1.05, its familiarity with, and exploitation of their target’s public disclosure obligations is a further escalation in a steadily increasing trend of pressure tactics by leading ransom groups.
