π Useful supporting research from @Unit42_Intel.
They assess add-mfa[.]com and myaccountapps[.]com as likely Com-affiliated, both previously shared through my UNC6671 tracking.
Iβve also shared additional infrastructure in recent posts that is linked to this ongoing campaign .
Unit 42 continues to track network infrastructure that is likely associated with Com-affiliated threat actors. Two of these domains are likely being used to target organizations operating across a wide array of industries. Details at https://t.co/iKP9Sz54Uy
