apt research, cyberwarfare, exploits, nation-state, zero-day
Three Buddy Problem - Episode 52: Fresh intelligence reports out of Europe and China: France’s ANSSI documents a string of Ivanti VPN zero-days ('Houken'), and Quanxin frames a stealth Microsoft Exchange-zero-day chain linked to a North American 'Night Eagle' threat actor. We dissect the technical bread-crumbs, questions the attribution math, and connects Houken to SentinelOne’s “Purple Haze” research.
Plus, the FBI’s claim that China’s “Salt Typhoon” has been “contained,” Iran’s Nobitex crypto-exchange breach (Predatory Sparrow torches $90 million and leaks the source code), Iranian cyber capabilities and sanctions avoidance.

apt research, cryptocurrency, cyberwar, nation-state, zero-day
Three Buddy Problem - Episode 51: Former Immunity/Trail of Bits researcher Hamid Kashfi joins the buddies for a fast-moving tour of cyber activities in the Israel-Iran war. The crew unpacks who 'Predatory Sparrow' is, why Sepah Bank and the Nobitex crypto exchange were hit, and what a $90 million cryptocurrency burn really means. Plus, radar-blinding cyberattacks that paved the way for Israel’s air raid, the human cost of sudden ATM outages and unpaid salaries, and the puzzling “Code Breakers” data leak that preceded it all.
Hamid shares on-the-ground context, the buddies debate whether cyber operations can sway a shooting war, and everyone tries to gauge Iran’s true offensive muscle under sanctions.

The dark hole of 'friendlies' and Western APTs

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.

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.

JAGS keynote: The intricacies of wartime cyber threat intelligence
May 9th, 2025 | 31 mins 7 secs
apt research, cti, nation-state, threat-intel, zero-day
Three Buddy Problem - Episode 45: (The buddies are trapped in timezone hell with cross-continent travel this week).
In the meantime, absorb this keynote presented by Juan Andres Guerrero-Saade (JAG-S) at CounterThreats 2023. It's a frank discussion on the role of cyber threat intelligence (CTI) during wartime and its importance in bridging information gaps between adversaries. Includes talk on the ethical challenges in CTI, questioning the impact of intelligence-sharing and how cyber operations affect real-world conflicts. He pointed to Ukraine and Israel as examples where CTI plays a critical, yet complicated, role. His message: cybersecurity pros need to be aware of the real-world consequences of their work and the ethical responsibility that comes with it.
