Three Buddy Problem - Episode 60: We dissect a fresh multi-agency Salt Typhoon advisory (with IOCs and YARA rules!), why it landed late, why the wall of logos matters (and doesn’t), and what’s actually usable for defenders: new YARA, tool hashes, naming ambiguity across reports, the mention of Chinese vendors, and a Dutch note that smaller ISPs were hit.

Plus, Costin details his hunting stack and philosophy (historic IOC/malware hoarding, fast pivots, and AI as analyst “wingman”) and a new Chinese APT report that may intersect with LightBasin and the murky PSOA world.

We also debate Google’s proposed “cyber disruption unit” versus Microsoft’s DCU (legal vs. “ethical” takedowns, PR, and business models); react to Anthropic’s report on real attacker use of Claude; note Amazon’s APT29 watering-hole disruption; and close on a fresh WhatsApp-to-ImageIO zero-click chain and practical phone OPSEC.

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

Three Buddy Problem - Episode 47: We unpack a multi-agency report on Russia’s APT28/Fancy Bear hacking and spying on Ukraine war supply lines, CISA’s sloppy YARA rules riddled with false positives, the ethics of full-disclosure after Akamai dropped Windows Server “BadSuccessor” exploit details, and Sekoia’s discovery of thousands of hijacked edge devices repurposed as honeypots.

The back half veers into Microsoft’s resurrected Windows Recall, Signal’s new screenshot-blocking countermeasure, Japan’s fresh legal mandate for pre-emptive cyber strikes, and why appliance vendors like Ivanti keep landing in the headlines.

Along the way you get hot takes on techno-feudalism, Johnny Ive’s rumored AI gadget, and a lively debate over whether publishing exploit code ever helps defenders.

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