Top Exploits
Different stack, same disease. One protocol trusted a backend key to mint money, another trusted two signatures and a conference handshake to protect a quarter of a billion dollars.
• Resolv got hit for ~$25M after a supply chain compromise ended with the attacker gaining signing authority over a privileged SERVICE_ROLE key. That one key could authorize USR issuance with no multisig, no on-chain mint ceiling, and no sanity check on the numbers, letting the attacker turn a few hundred thousand dollars in collateral into 80M unbacked stablecoins and a full-blown depeg.

• Drift Protocol lost ~$285M after a long social-engineering operation compromised multisig signers and handed the attacker admin control. With two pre-signed approvals and no timelock, they listed fake collateral, raised withdrawal thresholds, and emptied vaults in 128 seconds. (Read more)
Rekt Audit Broker
The big city sleeps, but the code never does. Neither do the crooks.
Rekt Audit Broker connects protocols with top-tier security firms. One request, multiple bids. Faster audits, fairer pricing, trusted partners.
Audits are cheaper than funerals.

RWA Security Risks and Best Practices: Securing Tokenized Assets End-to-End (34 min read)
RWA security breaks the moment teams pretend the smart contract is the whole system. Tokenized assets drag custody, legal enforceability, compliance logic, oracle dependencies, and off-chain operations into the blast radius, which means the real risk sits in the gaps between them.
The $27B Fraud Machine That Ran for Four Years Undetected (5 min read)
Huione didn’t just enable fraud - it industrialized it, turning Telegram into a full-stack marketplace for scams, laundering, and victim supply chains. The real failure wasn’t visibility but timing: by the time funds were traced, they were already gone.
Web3 Security Systems Explained: Every Major Approach Compared (10 min read)
The protocols that survive stack tools across the entire lifecycle, while the ones that don’t keep losing millions to the same access control and logic failures. Static analysis, fuzzing, audits, contests, bounties, monitoring - each catches something, each misses something, and the real failure is thinking one layer was ever enough.
Automated Spend Controls for AI Agent Micropayments (9 min read)
Letting agents pay autonomously sounds clean - until they start draining wallets in loops, following poisoned prompts, or signing with compromised keys. Without strict spend controls, one bad interaction turns “pay-per-use” into “pay-until-empty.”
Web3 Penetration Testing: A Practical Guide (6 min read)
Audits check the code. Attackers hit everything else. Modern exploits don’t stop at smart contracts; they move through APIs, wallets, cloud misconfigs, and key management until something breaks.
Other Security Stories
AI-powered banking malware turns fraud into an assembly line. Attacks are scaling faster than defenses, with hyper-realistic phishing, rapid variant generation, and zero-click exploits pushing financial theft into fully industrialized territory.
North Korean operatives aren’t just hacking DeFi - they’re building it from the inside. Fake identities, real skills, and years-long infiltration campaigns turn hiring pipelines into attack vectors, with Lazarus-linked actors embedding before the exploit even begins.
Attackers breached Bitcoin Depot’s internal systems and drained corporate wallets. Stolen credentials to settlement accounts let them move 50 BTC before access was cut, showing once again that wallet security fails long before the blockchain does.
U.S. Treasury is opening its cyber intel feed to crypto firms. Real-time threat sharing is finally extending beyond banks, as regulators admit the industry is too big - and too targeted - to stay outside the security perimeter.
Deepfake fraud kits are now bypassing KYC like it’s CAPTCHA. Real-time face swaps and voice cloning turn identity checks into theater, letting attackers walk through verification and straight into accounts with synthetic personas.
Security Events
OffensiveCon 2026
May 15 - May 16, 2026 | Berlin, Germany
A dense, highly technical offensive security conference focused on exploitation, vuln research, and reverse engineering.
OrangeCon 2026
June 4, 2026 | Amsterdam, Netherlands
A community-driven Dutch security conference that leans practical instead of polished, with trainings, talks, and enough hacker energy to keep it from turning into another badge-scanning industry expo.
FIRST Conference 2026
June 14 - June 19, 2026 | Denver, United States
One of the best places to hear from the people who actually run incident response, not just sell to it. Heavy on CSIRTs, coordination, operational lessons, and the unglamorous work of handling real incidents at scale.
fwd:cloudsec Europe 2026
September 7 - September 8, 2026 | London, United Kingdom
A cloud security event for people who have already suffered through real IAM mistakes, bad defaults, and misunderstood threat models.
GISEC Global 2026
September 21 - September 23, 2026 | Dubai, United Arab Emirates
A large-scale cybersecurity event focused on enterprise security, government initiatives, and regional cyber priorities, bringing together vendors, policymakers, and industry operators to shape the direction of the global security landscape.
Rekt Flashback
Two years ago, Grand Base showed how one compromised laptop can turn a token into a printing machine. A leaked deployer key let the attacker mint ~32.5M GB tokens and dump them on the market, draining ~$2M and collapsing the price by over 90% within hours. Same key risk, same missing audits, same reminder that in DeFi, you don’t need a bug - just control the wallet that controls everything.

This Hacker Kept Embarrassing the FBI
He didn’t hack systems. Instead, he bought access and walked in through doors everyone forgot to lock. Intel Broker turned stolen creds into a data empire, leaking governments and Fortune 500s like it was routine.
