Cracking the Fast16 sabotage malware mystery

The AI-powered 10x patch tsunami has arrived. Now what?

(Presented by TLPBLACK [https://tlpblack.net]: A cybersecurity intelligence platform focused on sharing curated, high-sensitivity threat insights and research with trusted security professionals.) Three Buddy Problem - Episode 98: We dive back into the fast16 malware discovery with fresh speculation that it's targeting spherical implosion simulations for Iran's nuclear program, and wonder who on earth is qualified to confirm this. Plus, thoughts on OpenAI's new three-tier cyber access program, Microsoft's MDASH harness, the 10x Patch Tuesday tsunami, Cloudflare's 1,100 layoffs blamed on AI, and why frontier-lab guardrails may just be elaborate security theater.

The disappointing death of big-game APT reporting

(Presented by TLPBLACK [https://tlpblack.net]: A cybersecurity intelligence platform focused on sharing curated, high-sensitivity threat insights and research with trusted security professionals.) Three Buddy Problem - Episode 97: We discuss the disappearing art of Windows APT paleontology, the absence of complex malware documentation, and why so much threat-intel research has slipped behind paywalls and into private rooms. Plus, a surge in AI-discovered bugs in Firefox and Chrome, a rough week for Linux security flaw disclosures, and the usual Ivanti and Palo Alto zero-day bulletins that ship without a single IOC.

Cracking the Fast16 sabotage malware mystery

(Presented by TLPBLACK [https://tlpblack.net]: A cybersecurity intelligence platform focused on sharing curated, high-sensitivity threat insights and research with trusted security professionals.) Three Buddy Problem - Episode 96: We're joined by WIRED writer Andy Greenberg to dig into SentinelLabs' bombshell FAST16 research, a newly deciphered piece of sabotage malware that predates Stuxnet by five years and quietly tampered with physics modeling software likely tied to Iran's nuclear program. We discuss the attribution rabbit hole (NSA? Israel? someone else?), the eerie "spiritual warfare" implications of corrupting scientific calculations, and Antiy Labs' very dialectical Chinese rebuttal. Plus, what AI reverse-engineering means for the next decade of cyber paleontology.

Mark Dowd on AI hacking, exploit chains, zero-day sales

(Presented by TLPBLACK [https://tlpblack.net]: A cybersecurity intelligence platform focused on sharing curated, high-sensitivity threat insights and research with trusted security professionals.) Three Buddy Problem - Episode 95: Vigilant Labs director Mark Dowd joins the show to shed light on the state of offensive research, the economics of the exploit market, and why "Mark Dowd in a box" isn't quite the threat the AI hype machine suggests. He talks through the daily stresses of running an offensive shop, how AI is reshaping vulnerability discovery, exploit development, and the pricing of full exploit chains. Plus, thoughts on Lockdown Mode and Apple's MIE, whether mitigations actually work or just push attackers toward less access, the rise of HarmonyOS and the Balkanization of device security, persistence, baseband attacks, GrapheneOS, and Samsung Knox. We discuss customer vetting and OpSec fears, policymakers who've never written an exploit, and the strange afterlife of The Art of Software Security Assessment, the 20-year-old book now possibly training data for the very tools coming for his job.

The Angry Spark APT Mystery: A Year-Long Backdoor, One Victim, Zero Attribution

(Presented by TLPBLACK [https://tlpblack.net]: A cybersecurity intelligence platform focused on sharing curated, high-sensitivity threat insights and research with trusted security professionals.) Three Buddy Problem - Episode 94: We discuss a mysterious, VM-obfuscated backdoor that lived undetected on a single U.K. machine for a year before disappearing, finding clues pointing to an elite-level APT intrusion that still evades broader industry coverage. Plus, connecting the dots across AI-driven vulnerability discovery, Microsoft’s massive Patch Tuesday, Jensen Huang talks cybersecurity, Mythos dangers and Chinese chips, and the quiet erosion of CVE enrichment at NIST.
