Train brake hack, GRU sanctions, Wagner war crimes, Microsoft's Chinese ‘digital escorts’

Three Buddy Problem - Episode 61: We cover a pair of software supply chain breaches (Salesforce Salesloft Drift and NPM/GitHub) that raises big questions about SaaS integrations and the ripple effects across major security vendors. Plus, Apple’s new Memory Integrity Enforcement in iPhone 17 and discussion on commercial spyware infections and the value of Apple notifications; concerns around Chinese hardware and surveillance equipment in US infrastructure; Silicon Valley profiting from China’s surveillance ecosystem; and controversy around a Huntress disclosure of an attacker’s operations after an EDR agent was mistakenly installed. Cast: Juan Andres Guerrero-Saade (https://twitter.com/juanandres_gs), Ryan Naraine (https://twitter.com/ryanaraine) and Costin Raiu (https://twitter.com/craiu).

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.

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.

Three Buddy Problem - Episode 58: The buddies react to the Brandon Dixon episode, digging into what it’s really like to scale products inside a tech giant, navigate politics, and bring features to millions of machines. Plus, an exploration of the AI cybersecurity gold rush, the promise and hype, and the gamble for startups versus the slow-moving advantage of incumbents. We revisit the Chinese "cyber militia" discussion and the looming AI “dot-com bubble,” the value of owning infrastructure, Nvidia and export controls, China’s manufacturing edge, and the geopolitics of supply chains.

Three Buddy Problem - Episode 57: Brandon Dixon (PassiveTotal/RiskIQ, Microsoft) leads a deep-dive into the collision of AI and cybersecurity. We tackle Google’s “Big Sleep” project, XBOW’s HackerOne automation hype, the long-running tension between big tech ownership of critical security tools and the community’s need for open access. Plus, the future of SOC automation to AI-assisted pen testing, how agentic AI could transform the cyber talent bottlenecks and operational inefficiencies, geopolitical debates over backdoors in GPUs and the strategic implications of China’s AI model development.

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.

Three Buddy Problem - Episode 55: A SharePoint zero-day exploit chain from Pwn2Own Berlin becomes a full-blown security crisis with Chinese nation-state actors exploiting vulnerabilities that Microsoft struggled to patch properly, leading to trivial bypasses and a cascade of new CVEs. The timeline is messy, the patches are faulty, and ransomware groups are lining up to join the party. We also revisit the ProPublica bombshell about Microsoft's "digital escorts" and U.S. government data exposure to Chinese adversaries and the company's "oops, we will stop" response. Plus, trusting Google's Big Sleep AI claims and a cautionary tale about AI agents gone rogue that wiped out a production database.

Three Buddy Problem - Episode 54: Europol busted pro‑Russian hacktivist crew NoName 057(16), the Brits announce sanctions on Russia’s GRU cyber units, Wagner‑linked “war influencers” streamed atrocities from Africa, and fresh tech worries ranged from a $500 RF flaw that can hijack U.S. train brakes. Plus, ProPublica on Microsoft’s China‑based “digital escorts,” Google’s headline‑grabbing AI‑found SQLite zero‑day, and OpenAI’s new task‑running agents. Meanwhile, Ukraine’s hackers wiped a Russian drone maker, ransomware crippled a major vodka producer, and another Chrome zero‑day quietly underscored how routine critical exploits have become.

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: Juan Andres Guerrero-Saade (https://twitter.com/juanandres_gs), Ryan Naraine (https://twitter.com/ryanaraine) and Costin Raiu (https://twitter.com/craiu).

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.
