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 her co-hosts ⁠⁠⁠⁠N2K Networks⁠⁠⁠⁠ ⁠⁠⁠⁠Dave Bittner⁠⁠⁠⁠ and ⁠⁠⁠Keith Mularski⁠⁠⁠, former FBI cybercrime investigator and now Chief Global Ambassador at ⁠⁠⁠Qintel⁠⁠⁠.

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 spooky special episode, our hosts ponder which threat actor, malware, or campaign name would be the most terrifying — from the spectral stealth of GhostRAT silently haunting your systems, to the deceptively sweet lure of ILoveYou that once spread chaos across the globe. Along the way, they share some of their favorite “ghost stories” from the cyber underworld — legendary incidents and infamous operations that still haunt defenders today — and explore why these names and their real-world impacts have left such lasting scars on the digital landscape.

Plus, we’ve cooked up a fun, mystery-solving video to accompany this episode — complete with spooky clues, masked sleuths, and a few laugh-out-loud moments that fans of classic cartoon detectives will appreciate. Check it out on YouTube and see if you can unmask the culprit!
