The infrastructure supporting command and control operations includes the domain update[.]ms-office[.]app. This observation indicates ongoing operations by Sidewinder, a threat actor known for targeting specific regions and sectors. The use of weaponized documents and deceptive domains mimicking legitimate Microsoft services demonstrates continued sophisticated social engineering tactics employed by this group."
