CypherTalk
CypherTalk is a twice-monthly podcast on the realities of cybersecurity and privacy in a world that’s moving faster than our defenses.
Hosted by Jade Doherty (who translates technical security into plain English) alongside rotating security and privacy experts — including co-host Stefan Beyer, co-founder of Oak Security — the show explores how modern cybersecurity attacks actually happen: not just through bugs in code, but through people, processes, supply chains, and the tools we rely on every day.
The show also looks at the latest trends in privacy and its supporting technologies, such as cryptography and zero-knowledge proofs.
Expect conversations that balance big-picture trends (AI-driven threats, privacy tech like zero-knowledge, shifting security standards) with practical takeaways you can apply immediately — whether you’re a developer, a founder, or simply someone who uses the internet.
Less hype. More clarity. Better security and privacy habits.

The Brave Browser with Kyle Den Hartog
Oct 6, 2026
Oct 6, 2026
52 min
Have you heard of Brave? Today we are joined by Kyle Den Hartog, a security engineer at the privacy browser. His path runs from penetration testing to self-sovereign identity to Web3, and that bridge between the Web2 and Web3 worlds runs through the whole conversation.
They start with how Brave made privacy mainstream: sane defaults and treating privacy as an emergent property that has to be fought for at every layer, with surveillance capitalism as the threat model rather than Tor-style maximalism. From there, why the biggest problems are no longer smart-contract bugs but browser and interface attacks, and a sharp point about domain expertise: crypto wallet teams often don't realise the browser already solves their problems (MetaMask's phishing list vs Safe Browsing, Rabby leaking browsing history vs hash-prefixing). It's also why Brave built its wallet into the browser rather than as an extension.
The most provocative stretch is Kyle's argument that Web3 is accidentally reintroducing cross-origin tracking. A wallet address is just a cookie: shared across sites on "connect," and far more revealing than any third-party cookie because it exposes where, when, and how much you spend. His fix is the thick client, moving transaction-building into the wallet so untrusted sites never receive the address.
The conversation then ranges across why zero-knowledge proofs aren't the panacea they're treated as (the "20 questions" problem), how ZK-gated compliance can recreate the gatekeeping Web3 set out to escape, why the early internet's lack of an identity layer was a feature, and a thoughtful take on age verification. Kyle closes on what Web2 and Web3 get wrong about each other, and his practical privacy advice beyond switching to Brave: a reputable audited VPN, then moving off the platforms that track you most.

Justus Hanna on AI Bug Hunting
Sep 17, 2026
Sep 17, 2026
46 min
Jade Doherty and Stefan Beyer speak to Justus Hanna, co-founder and CEO of Grego AI, a bug bounty hunter turned founder building AI that finds vulnerabilities human auditors miss.
Justus's path runs from hacking Novell networks as a kid, to Bitcoin in 2011, to picking up bug bounty hunting from scratch after a Wall Street layoff. The turning point came when his future co-founder showed him a system that found a high-severity bug in Lido's dual governance module, at a moment when every other AI bug hunter was producing pure slop. What sold him: the AI found bugs humans couldn't, faster and cheaper.
He explains Deep Invariant Analysis as a proprietary harness orchestrating hundreds of specialised agents across many models, built to go five or six layers deep into complex systems and chain exploits a human would be very unlikely to reach. They tackle the big claims head-on: the $27.7M exploit prevented, the $250K bounty, why the protocol stayed unnamed, and the awkward truth that verifying an "AI-only" find still comes down to reputation.
On the anxiety every auditor feels, Justus argues the harness is the moat, precisely because it's model-agnostic, and there's a candid detour on frontier-lab hype and safety theatre. The episode closes philosophically: his vision of an always-on "security operating system", and his advice to researchers, don't skip the manual apprenticeship. Learn the craft from first principles, then use AI as a superpower on top. Be Iron Man, not obsolete.

Security at Arbitrum with Lorenzo Sicilia
Aug 28, 2026
Aug 28, 2026
50 min
Jade Doherty and Stefan Beyer speak to Lorenzo Sicilia, Head of Technology at the Arbitrum Foundation, whose path into crypto runs through ConsenSys, Casval, and Outlier Ventures.
They open with the distinction that shapes everything else: the Foundation is the steward and legal wrapper of the DAO, not the team behind the tech. Lorenzo unpacks how it ran the Arbitrum Audit Program on the DAO's behalf, vetting a shortlist of thirteen audit firms and funding early-stage teams, and gets into the hard parts with Stefan: the "rubber stamp" risk when a Foundation-blessed audit becomes a trust signal, the friction of re-auditing when each iteration costs $50K to $250K, and the brutal cost-per-line metric the program can now benchmark across firms.
On security responsibility, Lorenzo is precise: the Foundation has none in the formal sense. Incidents fall to a 12-member Security Council, elected and rotated by the DAO. From there the conversation turns to what keeps him up at night, the L1-L2 trust boundary and the bridge, and why fraud proofs through BoLD have improved the picture, landing on his own preference for "code is law" while acknowledging where reality forces harder trade-offs.
The technical heart is Stylus, Arbitrum's WASM environment for writing contracts in Rust alongside the EVM. Lorenzo is unromantic about it: a second runtime widens the attack surface, and while safe Rust has real advantages, no language removes the authorisation, economic, and oracle pitfalls that actually cause losses, treating any language as "safe" is a mental trap. The episode also covers the freshly-shipped ZK-on-BoLD upgrade, the road to real-time proving, and why AI currently hands the red team a big advantage over the blue team, though Lorenzo is optimistic defenders can turn the same tooling back on their own code.
He closes with hard-won advice: authenticity and persistence over a polished demo, understand your oracles and dependencies, get key management right, and know when to switch from "fake it till you make it" to full paranoia, because in this industry, you don't get a discount.

Robert de Groot and Web3 Privacy Now
Aug 13, 2026
Aug 13, 2026
44 min
Jade and Stefan speak to Robert de Groot, a core contributor to Web3Privacy Now, the research collective and think tank behind the Cypherpunk Congress, and CFO at Gain.
Robert starts from an unexpected place: privacy isn't really about hiding; it's about autonomy, the ability to choose what you reveal, to whom, when, and in what form. He connects it to something bigger than data leakage, the loss of the room to experiment and to fail, and the quiet self-censorship that creeps in when everything is recorded. From there the conversation opens onto the spectrum of privacy, from the journalist in a conflict zone who will work from a terminal if it keeps them alive, to the rest of us who just want a group chat that isn't intercepted and won't tolerate bad UX to get it.
A big thread is the gap between personal privacy and business compliance, and why the two still don't align. Robert explains how Web3Privacy Now evaluates the 800-plus projects in its Explorer (the "hard variables," verifiable code over marketing claims), why "zero knowledge" and "private" have become marketing terms, and why privacy adoption lags even when the tooling is ready, the preventive-measure problem, the group effect, and cookie-banner fatigue. On the compliance side, he maps the middle ground: opt-in reporting, viewing keys, and selective disclosure (picking up the thread from our Jordi Baylina episode), including a one-time key you could hand your tax auditor and be notified when it's used.
He argues privacy will increasingly become a market-integrity feature, not just a civil-liberties one, shielding transaction amounts from competitors and MEV bots while keeping endpoints verifiable, and he closes on RWAs, why so many tokenisation projects quietly died on double-accounting overhead, and what "compliant by default" finally changes.

After several episodes focused on security, this one turns to privacy, with Emanuele Francioni, co-founder and CEO of Dusk, a blockchain built for privacy and institutional use cases.
Emanuele traces the through-line from a contrarian 2018 thesis to a live network to abstract financial instruments away from the intermediaries that leak both value and data. A core thread is the counterintuitive relationship between privacy and regulation. He disentangles anonymity from confidentiality, shows how privacy actually underpins rules like GDPR, DORA, and insider-trading law, and explains how Dusk encodes KYC, jurisdiction, and limits directly into the protocol.
Then it gets harder: on a privacy chain, a vulnerability can be exploited in the dark. Emanuele uses the recent Zcash unbounded-mint bug to explain why Dusk's approach has to be proactive, why the team shipped three security upgrades this year (Aegis and Boreas among them), and why simplicity is the best safeguard. On the AI arms race he's candid, seeing Fable in action for three days genuinely scared him, but his conclusion is pointed: AI doesn't replace security expertise; it makes it more valuable.

Most of our guests come at security from the outside, as auditors and researchers. Antonio Viggiano sits on the other side of the table: he's a Senior Security Engineer at the Monad Foundation, working on protocol fuzzing for the chain's consensus and execution clients.
Monad's architecture makes that a genuinely different problem. Unlike Ethereum, with its many interchangeable clients, Monad has a single pair: a C++ execution client and a Rust consensus client, both built by Category Labs. That tight coupling buys optimisations, but it also means a bug that looks real in one client is often quietly mitigated by the other. Test one in isolation and you drown in false positives.
That's where Monad Bugfinder came from, and the origin story is the opposite of what most people assume. It didn't start as a bug finder at all. It started as a triager, because the team was being flooded with AI-generated reports: convincing write-ups, plausible proofs of concept, and hours of human time spent working out which ones were real. Bug hunters optimise for recall. When you're the one receiving the reports, you need precision. Antonio walks through the validation gates that made the difference, why AI has a higher false positive rate than humans, and why the best human reviewers still find twice as many bugs as the best AI systems.

What does it actually mean to be "obsessed with AI for security"? In this episode of CypherTalk, Jade and co-host Stefan Beyer sit down with Prof. Arthur Gervais (UCL, affiliate faculty at UC Berkeley), known for foundational work on MEV, flash loan attacks, and AI-powered smart-contract security.
Arthur's core conviction sets the tone: AI is not a zero-sum game. Strong researchers can now find vulnerabilities ten times faster, and the right response is to onboard everyone as fast as possible rather than lock the tools down. The conversation goes deep on A1, the agentic system his team built that turns any LLM into an end-to-end exploit generator with one unambiguous goal: generate a profit. The hard part, he stresses, isn't building it, it's target selection.

In this episode of CypherTalk, Isaac Patka, co-founder of Shield3 and certification lead at the Security Alliance (SEAL), joins Jade Doherty and Stefan Beyer to discuss the human, operational, and governance risks shaping Web3 security. From early smart contract bug hunting to incident response wargames, SEAL 911, Safe Harbor, and the launch of SEAL certifications, Isaac explains why security is no longer just about audits and code.
The conversation explores how DeFi protocols can prepare for real incidents, why operational controls matter as much as smart contract reviews, and how AI is changing the threat landscape for both attackers and defenders. Isaac also shares practical insights on slowing down dangerous protocol actions, designing better incident response processes, and building a more mature security culture across crypto.

“An audit tries to prevent an incident and the war game tries to help you deal with an incident.”
“Social engineering works for a reason. Humans are fallible.”
“What is the slowest I can possibly make this and have it still be functional?”
“People don’t think during the design process about where they should build slowness into the protocol.”
“The core smart contracts have gotten a lot better, which has pushed the security risks to different parts.”
“If more people would care from day one about operational controls or circuit breakers, that’s what I would want.”
