DISCARDED: Tales From the Threat Research Trenches Threat Actor Theater: TA2541, TA558, and the Cyber Heist Crew TA582
Hello to all our cyber pals! In this episode of Discarded, host Selena Larson and co-host, Tim Kromphardt, are joined by Joe Wise, Senior Threat Researcher at Proofpoint for a deep dive into the chaotic brilliance of mid-tier eCrime actors—including the elusive TA582.
We explore recent activity from TA2541 and TA558—two groups known for their uncanny consistency and precision targeting—before shifting focus to TA582: a standout in today’s threat landscape. TA582’s multilayered, region-specific lures (think vintage car sales and fake speeding tickets) and complex delivery models are impressive compared to your typical cybercriminal.
Topics Include:
