Episode 19 - The Largest Malvertising Campaign Was Just Discovered
What if simply visiting a legitimate website was enough to infect your device with spyware without clicking a single thing? In this episode, we dive into three major cybersecurity stories exposing how attackers are exploiting trusted technologies, cloud identities and legacy authentication systems. Citizen Lab has uncovered how surveillance company Discover-Tech weaponised real-time advertising auctions to deliver Candiru spyware. We break down real-time bidding, JavaScript injection, invisible iframes, command-and-control infrastructure and how attackers can target specific devices without requiring a single click. Microsoft's October security updates are causing network authentication failures. We unpack NTLMv1, MS-CHAPv2, challenge-response cryptography and why decades-old authentication mechanisms are still creating security problems in modern enterprise environments. Attackers abused trusted Microsoft 365 application identities to access customer environments. We explain OAuth tokens, Entra ID service principals, stolen application credentials, privilege escalation and how attackers established persistence by creating additional application secrets. From spyware delivered through advertising infrastructure to cloud identity attacks that bypass traditional user authentication, this episode goes beyond the headlines to explain.
