Talking Points

Recent interactions between the hosts and their guests.

SEAL Certifications with Isaac Patka
Q: To what extent do AI tools change how you prepare for and conduct Seal certifications and war games?
AI enhances defenders by speeding up documentation, briefing—giving a rapid, contextual view of a protocol's risk profile and likely threat vectors before engagements—while also expanding attackers' capabilities, making ongoing training and operational controls even more critical.
Threat Intelligence with Peter Kacherginsky
Q: What are the biggest future attack concerns for 2026?
Persistent social engineering and supply chain attacks, and specifically smart contract watering hole/backdoor contracts that could drain users' funds long after initial compromises.
Threat Intelligence with Peter Kacherginsky
Q: Who mainly uses BlockThreat's indicators today?
Security companies, blockchain analytics firms, and researchers who need fresh indicators of compromise and exploit patterns to inform their defensive or investigative work.
Threat Intelligence with Peter Kacherginsky
Q: How do you ensure the intelligence is actionable rather than clickbait?
By building a database of patterns and root causes, adding practical actions readers can take today, and curating insights with a focus on real-world defensive measures rather than mere postmortems.
Threat Intelligence with Peter Kacherginsky
Q: What sparked the idea to start BlockThreat beyond reporting on hacks?
A lack of a regular, weekly resource for blockchain security news led to the creation of BlockThreat, combined with a personal interest in cryptocurrency security that evolved into a broader OSINT approach with actionable indicators.
