For the most part, it has been a quiet week on the ransomware front, with a few new reports, product developments, and attacks revealed.
Mandiant revealed this week that an Iranian threat actor is behind ransomware attacks on the Albanian government, likely in retaliation for an upcoming Iranian opposition groups’ conference.
Microsoft also announced this week that new Windows 11 builds in the Beta Channel had improved Microsoft Defender for Endpoint ransomware attack blocking capabilities.
This week we also saw an interesting research paper and Twitter thread on cyber insurance policies that are worthwhile reads.
Finally, we learned about ransomware attacks this week, including ones on Spanish National Research Council (CSIC), Semikron getting hit by LV ransomware, the German Chambers of Industry and Commerce, and Creos Luxembourg.

How Privilege Undermines Cybersecurity
In recent years, cyberattacks have cost firms countless billions of dollars, undermined consumer privacy, distorted world geopolitics, and even resulted in death and bodily harm. Rapidly accelerating cyberattacks have not, however, been bad news for many lawyers. To the contrary, lawyers that specialize in coordinating all elements of victims’ incident response efforts are increasingly in demand. Lawyers’ dominant role in cyber-incident response is driven predominantly by their purported capacity to ensure that information produced during the breach-response process remains confidential, particularly in any subsequent lawsuit.
