While last week was full of arrests and law enforcement actions, this week has been much quieter, with mostly new research released.
Security firms released reports on the types of cryptomixers used by ransomware gangs, a detailed report on Conti, and how Russian ransomware gangs are starting to work with Chinese hackers.
Today, US regulators also ordered banks to report cyber attacks within 36 hours if they impact their operations, the ability to deliver banking products and services, or the US financial sector’s stability.
Finally, a Tor negotiation site for the Conti ransomware gang was taken down, likely due to the release of its IP address in the PRODAFT report.
