Send us fan mail!

Today’s focus is on the elusive threat actor known as TA4903. But that's not all - we've got a special treat for you as well. Our longtime producer, Mindy, is joining us as a co-host, bringing her expertise and insights to the table, as we turn the mic around and interview, Selena! 

We explore recent research conducted by Selena and her team on TA4903’s distinct objectives. Unlike many cybercrime actors, TA4903 demonstrates a unique combination of tactics, targeting both high-volume credential phishing campaigns and lower-volume direct business email compromises.

We also dive into:

• TA4903 spoofs government entities like the Department of Transportation and the Department of Labor to lure victims
• Use of advanced techniques including evil proxy for multi-factor authentication token theft and QR codes for phishing campaigns
• Rising trends in cryptocurrency-related scams and other financial frauds
