Zero-day reality check: iOS exploits, MAPP in China and the hack-back temptation
August 22nd, 2025 | 2 hrs 32 mins
apt research, cyberespionage, nation-state, ransomware, zero-day
Three Buddy Problem - Episode 59: Apple drops another emergency iOS patch and we unpack what that “may have been exploited” language really means: zero-click chains, why notifications help but forensics don’t, and the uncomfortable truth that Lockdown Mode is increasingly the default for high-risk users. We connect the dots from ImageIO bugs to geopolitics, discuss who’s likely using these exploits, why Apple’s guidance stops short, and the practical playbook (ADP on, reboot often, reduce attack surface) that actually works.
Plus, we debate Microsoft throttling MAPP access for Chinese vendors, the idea of “letters of marque” for cyber (outsourced offense: smart deterrent or Pandora’s box?), and dissect two case studies that blur APT and crimeware: PipeMagic’s CLFS zero-day and Russia-linked “Static Tundra” riding seven-year-old Cisco bugs.
Cast: Ryan Naraine, Costin Raiu and Juan Andres Guerrero-Saade.

Rethinking APT Attribution: Dakota Cary on Chinese Contractors and Espionage-as-a-Service
August 1st, 2025 | 1 hr 51 mins
apt research, cyberespionage, nation-state, ransomware, zero-day
Three Buddy Problem - Episode 56: China-focused researcher Dakota Cary joins the buddies to dig into China’s sprawling cyber ecosystem, from the HAFNIUM indictments and MSS tasking pipelines to the murky world of APT contractors and the ransomware hustle. We break down China’s “entrepreneurial” model of intelligence collection, why public visibility into these threat actors is so hard to get right, and how companies like Microsoft get caught in the geopolitical crossfire.
Plus: a deep dive on suspected MAPP leaks and Sharepoint zero-days, Singapore targeted by extremely sophisticated China-nexus hacking group, soft censorship in corporate threat-intel, and whether the U.S. should rethink how it fills its intelligence gaps.
Cast: Dakota Cary, Ryan Naraine, Costin Raiu and Juan Andres Guerrero-Saade.

How did China get Microsoft's zero-day exploits?

Three Buddy Problem - Episode 53: We dig into news of the first-ever arrest of a Chinese intelligence-linked hacker in Italy, unpack the mystery behind HAFNIUM and how they somehow got their hands on the same Microsoft Exchange zero-days that researcher Orange Tsai discovered - was it coincidence, inside access, or something more sinister?
Plus, China's massive cyber capabilities pipeline, ‘theCom’ teenagers arrested in the UK after ransomware binge, and spyware attacks against Russian organizations.
Cast: Ryan Naraine, Costin Raiu and Juan Andres Guerrero-Saade.

The dark hole of 'friendlies' and Western APTs
May 30th, 2025 | 2 hrs 11 mins
apt research, cyberespionage, nation-state, ransomware, zero-day
Three Buddy Problem - Episode 48: We unpack a Dutch intelligence agencies report on ‘Laundry Bear’ and Microsoft’s parallel ‘Void Blizzard’ write-up, finding major gaps and bemoaning the absence of IOCs. Plus, discussion on why threat-intel naming is so messy, how initial-access brokers are powering even nation-state break-ins, and whether customers (or vendors) are to blame for the confusion.
Plus, thoughts on an academic paper on the vanishing art of Western companies exposing Western (friendly) APT operations, debate whether stealth or self-censorship is to blame, and the long-tail effects on cyber paleontology.
We also dig into Sean Heelan’s proof that OpenAI’s new reasoning model can spot a Linux kernel 0-day and the implications for humans in the bug-hunting chain.
Cast: Costin Raiu, Juan Andres Guerrero-Saade and Ryan Naraine.
