Introducing the React2Shell exploitation wave

(Presented by ThreatLocker: Allow what you need. Block everything else by default, including ransomware and rogue code.)

Three Buddy Problem - Episode 76: On the show this week, Costin walks through how a single Romanian documentary kick-started nationwide protests, exposing how corruption can be perfectly legal when the law itself is gamed, and why this moment feels different, darker, and more consequential than past flare-ups.

Plus, news on the React-to-Shell exploitation wave overwhelming the internet, why patching is structurally hard, and how APTs and criminals are converging on the same fragile dependency chain. Along the way, they take aim at Microsoft’s shrinking transparency, the limits of vendor trust, and what it really means when defenders are told (again) to just patch and pray.

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