    When legit is the trick: Phishing’s sneaky new moves.

    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 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.

    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 episode, we dive into supply chain attacks through the lens of a massive Android malware campaign that infects devices before they ever reach users, embedding itself in firmware and reseller-installed system images. We connect the dots to other high-impact supply chain incidents—from SolarWinds to the recent F5 breach—and share new intelligence on Android devices compromised during manufacturing and distribution in China. Together, these cases highlight how attacks at the source can quietly scale, persist, and evade traditional defenses.
