ABOUT THIS EPISODE
In this episode of the Microsoft Threat Intelligence Podcast, host Sherrod DeGrippo is joined by Microsoft researchers Kelsey Clapp and Anna Seitz to examine two major cybercrime campaigns. The team unpacks Storm 2561’s use of SEO poisoning to distribute Trojanized software like SilentRoute and Bumblebee, stealing VPN credentials and paving the way for ransomware brokers.
They also dive into Storm 1811’s ReadBed malware, a loader deployed through bold social engineering tactics, such as fake IT help desk calls via Teams, that enable lateral movement and ransomware deployment. The discussion highlights how modern threat actors exploit trust, extend attack chains, and continually evolve their techniques, underscoring the importance of vigilance, strong security controls, and verifying before trusting.
In this episode you’ll learn:
-
How Storm 2561 uses SEO poisoning to trick users into downloading Trojanized software
