Three Buddy Problem - Episode 83: Poland's CERT documents a rare, explicit wiper attack on civilians in a NATO country, including detailed attribution of a Russian government op targeting the electric grid in the heart of winter. We examine why this crosses a long-avoided threshold, why attribution suddenly matters again, and what it says about pre-positioned access, vendor insecurity, and the shrinking gap between cyber operations and acts of war.

Plus, another Fortinet fiasco, a new batch of Ivanti zero-days under attack, an emergency patch from Microsoft and the return of the mysterious KasperSekrets account.

Cast: Juan Andres Guerrero-Saade, Ryan Naraine and Costin Raiu.
