Mastering the "Auditing Mindset" with this roadmap. Spotting vulnerabilities in real-time requires pattern recognition, not just theory. Massive thanks to @kingoooooX1 for the curation and @ValvesSec for building the gold standard in auditor training. Training on these patterns is exactly how I level up for current challenges like K2. Highly recommended for any serious auditor.

iam sharing best resources to train web3 security in my opinion for the new auditors. its 2026 and nothing is more than learning resources. i will be myself doing it to change my auditing mindest. 1- solana audit arena by the goat @0xcastle_chain. best place to practice solana security. my two cents, before we said there are no solana contests, but now there are no contests, its bug hunting era and solana knowledge will give huge advantage and make you super rare. 2- training.valvessecurity.com by @ValvesSec underrated, completing all the challengess alone will make you another auditor, and you can be ready for real world hunting. 3- shadow auditing @code4rena contests nothing to say, it's best place to learn for long time. start with small codebases and try to pick one category at a time. 4- real world hunting on @HackenProof thats the final stage- where you can use the knowledge you have on-chain its simple roadmap but hard to apply.

Cross-chain Security: Insights from the ZetaChain Incident The ZetaChain GatewayEVM exploit highlights the ongoing risks in cross-chain infrastructure. With cross-chain transactions paused for over 9 hours, the focus remains on rapid containment and recovery. Key takeaways: - Gateway Complexity: Bridges are intricate infrastructures-they remain prime targets for sophisticated attack vectors. - Incident Response: Immediate transaction suspension is crucial. ZetaChain’s team has identified the vector and is currently deploying a patch. - Limited Impact: Reports confirm only internal team funds are affected, with no impact on user assets. As this situation unfolds, real-time monitoring of the official status page is essential. Security in Web3 is a continuous effort-from resilient code to proactive infrastructure management.

The "Ghost" Contract Vulnerability: Lessons from Scallop’s Incident Scallop’s exploit reminds us: a protocol's security depends on its entire footprint, not just the core logic. Targeting a deprecated contract is a classic "forgotten attack surface" exploit. Takeaways for builders & auditors: - Audit the Legacy: Deprecated code is still an attack vector. - Decommission Properly: Don't just ignore old contracts-isolate or remove them entirely. - Broaden the Scope: Security covers every linked contract, not just the "hot path." As auditors, we must look beyond the main features to find the vulnerabilities hidden in the "ghosts" of the codebase.

✅ INCIDENT UPDATE We have unfreezed the core contracts and all operations have resumed. The issue was not related to the core protocol and was isolated to a deprecated rewards contract. User deposits were not impacted and all funds remain safe. Withdrawals and deposits are now operating normally. We will share more details soon. Thank you for your support as we continue to monitor and strengthen the protocol! 🐚

The "Dark Forest" is getting crowded. Bot 0x841 is sandwiching 1500+ users/day, even those using private mempools. This is a wake-up call for the industry. For DeFi Auditors, the focus must shift: - Beyond the Contract: Is your protocol truly MEV-resistant? - Audit Standard: MEV protection should be a non-negotiable part of our audit reports. Great catch by @dataalways. In DeFi, infrastructure security is just as critical as code logic.

Meet 0x841: a fresh sandwich bot lurking in the dark forest--currently attacking about 1500 users per day, while going almost unnoticed. What's particularly scary: most of the victims are using private mempools and should be protected.

A common mistake we see in smart contract development: trusting user-provided inputs without strict validation. In auditing, we treat every input as potentially malicious. Always implement 'Zero Trust' logic within your contracts. Don't wait for a hack to find out where your assumptions failed. What’s one security practice you prioritize in your development process? Let’s discuss. #Web3Security #SmartContract #Audit

Post-Mortem: A Look Back at Recent Web3 Security Failures. The data from the past week (April 13–19) shows a concerning surge in exploits. These aren't just incidents; they are critical lessons for every project builder. Reviewing these incidents reinforces one core principle: security is not a 'set-and-forget' task. The surge in recent losses highlights the urgent need for: 1️⃣ Rigorous logic-flow validation. 2️⃣ Constant monitoring of emergency upgrade paths. 3️⃣ Proactive stress-testing against cross-chain vulnerabilities. Don't wait for your project to become a statistic. Security should be the foundation of your protocol, not an afterthought.

KelpDAO Exploit Analysis The recent KelpDAO exploit on @arbitrum isn't just an incident-it’s a critical lesson in logic-level security. The attacker leveraged emergency upgrade powers to bypass authentication entirely. This highlights a fatal flaw: relying on infrastructure while neglecting internal logic controls. Bypassing msg.sender for caller-controlled parameters completely invalidated L2 authentication. For cross-chain protocols, rigorous auditing of emergency upgrade paths is mandatory. Key Takeaway: Never assume L2 entry points are secure by default. Secure your logic, secure your bridge.
Arbitrum@arbitrum

The Arbitrum Security Council has taken emergency action to freeze the 30,766 ETH being held in the address on Arbitrum One that is connected to the KelpDAO exploit. The Security Council acted with input from law enforcement as to the exploiter’s identity, and, at all times, weighed its commitment to the security and integrity of the Arbitrum community without impacting any Arbitrum users or applications. After significant technical diligence and deliberation, the Security Council identified and executed a technical approach to move funds to safety without affecting any other chain state or Arbitrum users. As of April 20 11:26pm ET the funds have been successfully transferred to an intermediary frozen wallet. They are no longer accessible to the address that originally held the funds, and can only be moved by further action by Arbitrum governance, which will be coordinated with relevant parties.

AI vs. Auditor: The Future of Smart Contract Security Is AI coming for our jobs, or is it just the ultimate tool? Looking at current security workflows, the reality is clear: AI has become exceptional at pattern recognition, architectural summarization, and automating repetitive tasks. However, it still lacks the deep context and logical intuition required to identify complex, protocol-specific vulnerabilities. So, how do we ensure we stay relevant? Shift from "Code Reviewer" to "Security Architect": Focus on understanding the economic and systemic risks of a protocol-areas where AI currently struggles. Master AI as a Force Multiplier: Don't ignore it. Use AI to speed up the mundane parts of the audit so you can dedicate more time to high-value, deep-logic analysis. Human-in-the-Loop is Non-Negotiable: A vulnerability scan is just the starting point. The human element-the ability to connect seemingly unrelated logic flows-is what separates a simple tool from a comprehensive audit. The future of auditing isn't "AI vs. Human." It’s "Auditor + AI."

Why Audit Competitions are the best "Gym" for your Security career. I often get asked how to move from "learning Solidity" to "finding actual bugs." My answer is always the same: Audit competitions. Participating in these events (like the current K2 audit) isn't just about the prize pool ($135k in this case). It’s about: 🔹 Pressure-testing your process: Can you actually find a logic bug under a deadline? 🔹 Diversity of thought: Reading other auditors' reports after the event is the fastest way to learn new attack vectors. 🔹 Real-world edge cases: You won’t find these bugs in tutorials. They are hidden in complex architectural designs. The K2 audit started 2 days ago-plenty of time to get your hands dirty with their RWA/Stellar architecture. Even if you don't submit, just reviewing the code is a massive level-up. Don’t just watch others hunt-start building your own muscle memory.

Rhea Finance Exploit Update: It wasn't just the Oracle. The official post-mortem reveals a critical logic bug in the Slippage Protection mechanism (margin_trading.rs#L102). By miscalculating aggregated swap outputs, the attacker drained $18.4M. A stark reminder that complex DeFi math requires more than just a standard audit.

Oracle Manipulation Strikes Again: Rhea Finance Exploit Explained Rhea Finance was just hit for $7.6M on @NEARProtocol. As an auditor, this case is a classic (yet painful) lesson in Oracle Security. How did it happen?The attacker exploited a "Fake Token Pool" logic. By creating a worthless token and manipulating its price within a low-liquidity internal pool, they misled the protocol's Oracle system. The Exploit Flow: 1️⃣ Attacker creates a fake token. 2️⃣ Manipulates its price in an internal/unprotected pool. 3️⃣ Uses the "inflated" fake token as collateral. 4️⃣ Drains $7.6M in real assets (USDT, NEAR, etc.). Auditor's Takeaway:Trusting a single, internal liquidity pool for price data is a fatal flaw. 🔹 ALWAYS use decentralized oracles (like @Chainlink or @PythNetwork). 🔹 NEVER allow unverified/low-liquidity tokens as collateral without a strict whitelist and price-impact limits. Security isn't just about clean code; it's about robust economic logic. Stay vigilant!
Rhea Finance@rhea_finance

The RHEA team is aware of an incident affecting the protocol. As a precautionary measure, we have temporarily paused the contracts while we conduct a thorough investigation. We are working closely with key partners, stakeholders, and security experts. Protecting user positions is our immediate priority, and our team is focused on minimizing any potential impact. RHEA team has reached out to the responsible party through on chain transaction. #9BfCGUigv3w8TFRx5n8t5Qira62oBcrcAp2fVeGfFZVC" target="_blank" rel="nofollow noopener">nearblocks.io/txns/6r5c2iZig…
