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. This week, our hosts dive into the evolving threat of software supply chain attacks and the growing risks facing the open-source ecosystem. As developers increasingly rely on third-party packages and AI-powered coding tools, attackers are finding new ways to abuse trusted software to reach a wider range of targets. The discussion explores why these attacks are becoming more common, what recent incidents reveal about the state of software security, and what organizations can do to better protect themselves.

On this episode of Mythb…oops, we mean Only Malware in the Building, our hosts take on some cyber myths. Dave busts the idea that small organizations aren’t targets, Selena digs into whether AI is really making attackers smarter, and Keith breaks down why identifying a hacker doesn’t mean law enforcement can just go make an arrest. Three myths, one truth: in cybersecurity, nothing is ever that simple.

On this episode, we discuss findings from the Sophos Active Adversary Report 2026 by Sophos, highlighting how identity-related weaknesses like compromised credentials and gaps in MFA continue to drive a majority of security incidents. The conversation explores how attackers are moving faster, often operating after hours, and how a growing number of threat groups is adding to the complexity.

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, our hosts start with a deep dive into artificial intelligence and its impact on cybersecurity. They explore AI-driven malware, accelerated attack chains like the Fortinet case, and how defenses are adapting—but emphasize that good security hygiene still works. They also debate AI’s effects on creativity and society, highlighting the importance of guardrails and responsible use.

On this episode, our hosts discuss how attackers are increasingly abusing legitimate, trusted Microsoft workflows to make phishing campaigns more convincing and harder to spot. In device code phishing, victims are socially engineered into completing a real Microsoft OAuth login flow, inadvertently granting attackers valid access tokens without ever sharing a password. They also examined abuse of Microsoft 365 Direct Send, which allows threat actors to send phishing emails that appear to originate from inside an organization, reinforcing a broader shift toward weaponizing built-in cloud services rather than relying on obviously malicious infrastructure.
