New BlockThreat is out! This week: how your defenses can make you vulnerable, how patient attackers beat reactive onchain monitoring, surprising results from the latest AI audit tool comparison, attackers vs. audit scopes, and much more.
Blockchain Threat Intelligence@blockthreat

BlockThreat - Week 11, 2026 📈 14 incidents, $6M in losses. Details inside 💰 Ethereum bug bounty set at $1M 🤬 DoJ seeks October retrial of Roman Storm 💸 Yet another Venus Protocol hack. $5M. Oddly reminiscent to the @eulerfinance compromise exactly 3 years ago.

Old code isn’t safe just because it’s old. On CypherTalk podcast (Ep. 4), @iphelix, founder of @blockthreat joins @beyer_st and @pumpkinGMI to explain why relying on legacy infrastructure and the “Lindy effect” is dangerous and why learning from past exploits is critical.

NEW: Bitcoin educator Andreas Antonopoulos says he will stop producing livestreams and new content due to health issues. Antonopoulos previously said he has been suffering from debilitating migraines and has tried nearly every treatment available, but nothing has successfully stopped them.

@lonelysloth_sec @Montyly @VitalikButerin Tradsec went through similar cycles a few times the last 4 decades. Network scanning tools, code scanners, fuzzers, exploit dev kits, etc. Media freaks out, a few get hacked, and later everyone gets safer once the same innovation is adopted as another layer of defense.

@Montyly @VitalikButerin Yes I think it’s exactly like a new fuzzer+static analyzer. You find a bunch of bugs at first. Then you stop finding new bugs. And I agree it will be most useful early in the dev cycle. Depending on where you are in the dev cycle even false positives can be valuable.

One application of AI that I am excited about is AI-assisted formal verification of code and bug finding. Right now ethereum's biggest technical risk probably is bugs in code, and anything that could significantly change the game on that would be amazing.

My favorite pieces are probably the ones involving a certain nation state actor. I’ll leave it to you to guess which one inspired this edition 😉

Did you ever wonder what is behind the art in the @blockthreat newsletter? Every edition features an art piece tied to that week’s core security theme or incident. I chose a distinct Wild West style as a reminder that our industry is still very much a frontier. Here are a few of my favorite pieces. 🧵

Three years later, Euler is still a good reminder not to rush “just one tiny little feature” without proper audits, especially in an era when AI may reassure you it looks fine or worse have authored it. Be safe. Not all hacks have happy endings like this one.
BlockThreat Today@blockthreat_2da

Mar 13 2023: Euler Finance was drained for roughly $200M in just 15 minutes. The attacker exploited a recently introduced and unaudited donation feature to trigger mass liquidations.

9 incidents, $3.5M stolen, and 50+ AI bug hunting tools and counting. This week’s exploits and disclosures hit battle tested codebases once thought safe. This week’s @blockthreat edition covers the defensive AI tools and research that can help teams stay ahead of the next Euler scale mistake.
