Welcome in! You’ve entered, Only Malware in the Building. Join us each month to sip tea and solve mysteries about today’s most interesting threats. Your host is Selena Larson, Proofpoint intelligence analyst and host of their podcast DISCARDED. Inspired by the residents of a building in New York’s exclusive upper west side, Selena is joined by N2K Networks Dave Bittner —and our newest totally unbiased co-host, Archy, a highly sophisticated AI robot who swears they have no ulterior motives (but we’re keeping an eye on them just in case). Being a security researcher is a bit like being a detective: you gather clues, analyze the evidence, and consult the experts to solve the cyber puzzle. On this episode, we talk about the latest shake-ups in the fake update threat landscape, including two new cybercriminal actors, fresh Mac malware, and the growing challenge of tracking these evolving campaigns.
Analysis Summary
