Our highlight in this Roundup is Incident 20200616A: Suspected Kimsuky “AutoUpdate” Malware. ThreatConnect Research identified a malware sample suspected to be associated with Kimsuky (a DPRK-based group) due to behaviors similar to a sample reported on the ESTsecurity ALYac Blog.

The blog above describes recent activity related to a campaign first seen in December of 2019 dubbed Operation Blue Estimate. One of the files observed in this attack, C315DE8AC15B51163A3BC075063A58AA, was identified as a downloader in ESTsecurity’s analysis.

Based on the string deobfuscation routine and URL parameters observed in the file above, an additional file FF0DDDC847825F13001B08661B2C7D0D was identified by our team, along with the hard-coded C2 domain dept-dp.lab.hol[.]es.
