New analysis from Crimson Canary has indicated that by growing strong detection protection for the methods adversaries abuse most frequently, safety groups can obtain defense-in-depth in opposition to the numerous threats that leverage these methods and the broader developments that dominate the infosec panorama.

The report is organized into three cascading sections: developments, the threats that comprise these developments and the MITRE ATT&CK® methods which are leveraged by these threats. Every part consists of intensive steerage that safety groups can use to mitigate, stop or detect the malicious exercise described within the report. 

The largest development in 2021, not surprisingly, was ransomware. Counterintuitively, Crimson Canary doesn’t detect a lot ransomware, and the rationale for that’s most likely the only most vital takeaway from the report. Ransomware is nearly all the time the eventual payload delivered by earlier-stage malicious software program or exercise; in the event you detect the threats that ship the ransomware, you cease the ransomware earlier than it arrives. So, how do you detect these threats? Deal with the methods that adversaries are almost certainly to leverage. 

Graphic. Ransomware is split into three threats: cobalt strike, Qbot, and SocGholish. Cobalt Strike can be combatted with Powershell, Rundll32, and obfuscated files or info. Qbot can be defended against with ingress tool transfer, masquerading, and Rundll32. SocGholish can be fought against with masquerading, Powershell, and Ingress Tool Transfer.

Of the highest 10 threats Crimson Canary noticed in 2021, 60% are ransomware precursors (i.e., threats that’ve been identified to ship ransomware as a follow-on payload). Extra staggering is {that a} full 100% of the highest ATT&CK methods have been used throughout an tried ransomware an infection. 

For example, a big plurality of ransomware infections contain the usage of a command and management (C2) product known as Cobalt Strike — Crimson Canary’s second-ranked menace. Cobalt Strike, in flip, leverages ATT&CK methods like PowerShell, Rundll32, Course of Injection, Obfuscated Information or Data and DLL Search Order Hijacking, all of that are within the prime 10. If you happen to develop broad detection protection for these methods, you then’ve acquired a fantastic shot of detecting Cobalt Strike and stopping ransomware infections.

The report relies on evaluation of the greater than 30,000 confirmed threats detected throughout Crimson Canary’s buyer base in 2021.
