Episode Details

Today’s episode of Prime Cyber Insights provides a deep technical analysis of GigaWiper, a destructive Windows backdoor that combines multiple legacy tools into a unified platform for disk wiping, fake ransomware, and espionage. Linked to the CyberAv3ngers group, GigaWiper represents a shift toward modularity in state-sponsored cyber operations. We also breakdown the tactics of Helix, a new data-extortion group using manager-impersonating vishing calls to bypass multi-factor authentication in SharePoint environments. Additional coverage includes the exploitation of Meta's business account infrastructure for phishing and critical unpatched hardcoded credentials in Tenda router families.
