UAC-0102 is a threat actor group targeting UKR.NET users through phishing attacks. They distribute emails with HTML file attachments that redirect users to a fraudulent website to steal authentication data. Security teams can use Sigma rules to detect their phishing campaigns and leverage IOCs provided by CERT-UA to hunt for their activity in SIEM or EDR environments.
