Roundup Highlight: More Kimsuky “AutoUpdate” Malware

 

20200618A: Suspected Kimsuky “AutoUpdate” Malware

 

Our highlight in this Roundup is Incident 20200618A: Suspected Kimsuky “AutoUpdate” Malware. ThreatConnect Research identified an additional malware sample likely associated with Kimsuky (a DPRK-based group) due to behaviors similar to a sample reported on the ESTsecurity ALYac Blog, which was also referenced in last week’s Research Roundup Blog.

Like last week’s file, this sample (1E14DED758C5DD7B41FE20297935EEEF) is also similar to the downloader (C315DE8AC15B51163A3BC075063A58AA) identified in the above blog based on behaviors including a string deobfuscation routine and specific URL parameters.

Of note, it was uploaded to VirusTotal with the filename bmail-security-check.scr which shares strings with the embedded obfuscated command and control server at security-confirm.bmail-org[.]com. This server was live as of Jun 18, 2020 16:54 UTC. For more details, see the Incident in the ThreatConnect Common Community.
