We would also like to highlight two specific sets of rules:
- 52445 - 52448: These rules prevent a variant of malware from the Gamaredon APT from making outbound connections during its various phases. The hacking group, which has been active since 2013, recently started a wave of attacks in Ukraine against government agencies, journalists and military branches. Security researchers say these attacks were still active as of Dec. 6 after starting around mid-September. Joanne Kim wrote these rules.
- 52427 - 52429: These rules protect against a variant of the DoppelPaymer ransomware. Talos recently discovered a command and control server that held DoppelPaymer files, and Microsoft recently released an alert, warning users of the ransomware. There have been misleading reports that DoppelPaymer is spread through the infamous "BlueKeep" exploit, though Microsoft researchers say that is not true. Kristen Houser wrote these rules.
