The REvil ransomware gang's attack against the US software company Kaseya in 2021 is not only amongst the largest ransomware attacks of all time, but it's also one of the most intriguing. It involves the use of zero-day software vulnerabilities known only to a handful of people, a race between attackers trying to snare ransom payments and defenders developing a patch, and a secret operation that hacked back against the REvil hackers. And in the end, a rare action happened: Someone was actually arrested. This episode of The Ransomware Files also coincides with the release of new technical information from the Dutch Institute for Vulnerability Disclosure about the software vulnerabilities that were exploited by the ransomware gang. The information, which describes the vulnerabilities in Kaseya's Virtual Systems Administrator software, can be found on DIVD's website.
