Cloudflare deployed WAF protections for 2 critical WordPress vulns before public release: unauthenticated RCE + SQLi. If your WordPress traffic is proxied through Cloudflare, the new rules help reduce exposure while you patch. Fixes are in 7.0.2, with backports to 6.9.5, 6.8.6, and 7.1 Beta 2. Patch anyway. WAF is not a substitute for updating. cfl.re/4yrOFNH

Grok Build news: @SpaceXAI is back with a banger! Some of the best changes in 0.2.105: • Grok 4.5 is now the default model, with high, medium, and low reasoning effort • /btw now works inside grok --minimal • New /summarize command for instant session summaries • Local shell tools now inherit your normal environment variables, aliases, and functions • Improved long-session compaction • Global rules are now discovered correctly • Smoother scrolling under load and on slow connections Plus a long list of bug fixes. Another seriously strong update.

















19 DeFi exploits that weren't in the open-source record — now fully reproducible. If you work in smart-contract security, you know DeFiHackLabs — the standard, comprehensive library of reproducible on-chain exploit PoCs. A handful of exploits just aren't in it. We found 19, analyzed each one end-to-end, and published everything: 🔹 Foundry PoCs (offline-reproducible, exact on-chain profit) → github.com/sanbir/evm-hac… 🔹 Loadable PoC bundles → github.com/sanbir/evm-hac… 🔹 Interactive EVM Playground pages — step through each exploit opcode-by-opcode, with the vulnerability and every exploit step marked → crypto.training/hacks All 19, newest first: • BarnBridge SMART Yield (DAO governance capture) — crypto.training/hacks/2026-07-… • Bonzo Lend / Supra oracle (BLS zero-signature price forge) — crypto.training/hacks/2026-07-… • Hinkal (legacy-note multi-nullifier double-spend) — crypto.training/hacks/2026-07-… • Drips DaiHub (uint128→int128 cast) — crypto.training/hacks/2026-07-… • Gnosis Pay / Zodiac Delay (EIP-1271 signature bypass) — crypto.training/hacks/2026-06-… • ATOHook (Solady ReentrancyGuard storage collision) — crypto.training/hacks/2026-06-… • JaredFromSubway MEV bot (residual ERC-20 approvals) — crypto.training/hacks/2026-06-… • BoostHook (leveraged long, no post-open solvency check) — crypto.training/hacks/2026-05-… • Aurellion Labs (unprotected diamond re-init) — crypto.training/hacks/2026-05-… • ONTR (zero-owner onlyOwner free mint) — crypto.training/hacks/2026-05-… • BlastFOMOVault (claimBonus clone-churn) — crypto.training/hacks/2026-05-… • HeisenbergHook (Uniswap v4 fee-path hijack) — crypto.training/hacks/2026-05-… • Sat1Hook (grindable hook identity) — crypto.training/hacks/2026-05-… • QNT Reserve (EIP-7702 + permissionless BatchCall) — crypto.training/hacks/2026-04-… • Yearn stETH Accumulator (missing execute() auth) — crypto.training/hacks/2026-04-… • Blockchain Bets (ERC-1155 stake/transform inflation) — crypto.training/hacks/2026-04-… • TTSwap Market (permissionless initGood mispricing) — crypto.training/hacks/2026-04-… • WUKONG Staking (classical reentrancy in unstake) — crypto.training/hacks/2026-03-… • FoomCash / FOOM Lottery (Groth16 verifier with gamma == delta) — crypto.training/hacks/2026-02-… One recurring lesson: the interesting part of an attack is often not the drain. BarnBridge is the clearest example — the money left through the front door of the DAO. The real exploit was obtaining access: buy ~$2,200 of a dead governance token, stake it with a lock multiplier, and pass a proposal because quorum was measured on raw stake while votes counted multiplied power. So we reproduced the governance capture, not just the payoff. And you can do all of this yourself. github.com/sanbir/evm-hac… is an open-source, fully local EVM Playground. Point it at any exploit transaction — it pulls the verified sources, replays the whole thing opcode-by-opcode, and lets you mark the vulnerability and the exploit execution steps. Then share your PoC however you like — open a PR to github.com/sanbir/evm-hac…, or publish it in your own repo, on IPFS, anywhere. No lock-in: the analyzer doesn't depend on evm-hack-poc or crypto.training. The best way to understand an exploit is to reproduce it. The second best is to make it easy for the next person to. #Web3Security #SmartContracts #DeFi #EVM #Solidity #BlockchainSecurity #OpenSource
