On Tuesday, notorious Russian-affiliated ransomware cartel BlackCat claimed to be holding e-discovery platform Casepoint hostage, according to a tweet posted by user FalconFeedsio:

According to the tweet, the sample posted by the hackers on their ALPHV/BlackCat dark web victim blog contains "visa details, a report, a certificate, etc." BlackCat claims to be holding over two terabytes of Casepoint's data hostage, including attorney files and "many other things you have tried so hard to keep."
