Web3 and DeFi protocols gather to increase sector’s security

The cryptocurrency space is experiencing a scorching summer, but not just in terms of token prices. Decentralized Finance (DeFi) protocols and Web3 projects are witnessing a surge in liquidity, but this growth comes with a scorching downside: heightened security vulnerabilities.

Growing Complexity, Expanding Attack Surface

As DeFi matures, its intricate systems are creating more opportunities for attackers to exploit. June 2024 alone witnessed several high-profile security breaches:

• UwU Lend’s Smart Contract Meltdown: A critical vulnerability in UwU Lend’s smart contract resulted in a staggering $20 million loss.
• Kraken’s “Ethical Hack” Gone Wrong: A security firm, Certik, conducted an “ethical hack” on Kraken, accidentally stealing $3 million before returning the funds amidst public scrutiny.
• Velocore Exchange Hemorrhage: The Velocore exchange suffered a multi-pronged attack, losing $6.8 million across its ZKSync and Linea pools.

These are just a few examples. ImmuneFi, a prominent bug bounty platform, reported a staggering 91% increase in exploits during Q2 2024 compared to the same period in 2023, with over $500 million stolen.

DeFi’s Achilles’ Heels

Several factors are contributing to this rise in exploits:

• Multi-Chain DeFi: DeFi is venturing beyond the Ethereum blockchain and flourishing across various Layer 2 (L2) blockchains. This multi-chain expansion introduces new attack vectors, with bridges, smart contracts, and wrapped assets in these chains becoming potential security holes.
• MEV Attacks on the Rise: Malicious actors are employing MEV (Miner Extractable Value) attacks, like sandwich attacks, to steal from unsuspecting DEX (Decentralized Exchange) traders. ZachXBT, a renowned blockchain security researcher, recently exposed a high-profile MEV attacker.
• Individual Wallet Vulnerabilities: Hackers are increasingly targeting individual wallets, employing tactics like fake addresses, malicious smart contracts disguised as legitimate applications, and phony NFT purchase links to steal user funds.

The Bug Bounty Brigade

The Web3 community is actively countering these threats by launching bug bounty programs and competitions. These initiatives incentivize ethical hackers to identify and fix vulnerabilities before malicious actors exploit them. Here are some key developments:

• MakerDAO Backs SherlockDeFi: MakerDAO, a leading DeFi protocol, is making a significant investment of $1.35 million in SherlockDeFi, a security firm specializing in DeFi audits. Sherlock boasts a proven track record, having successfully completed 167 audits and identified over 383 critical bugs to date.
• ImmuneFi’s Million-Dollar Challenge: ImmuneFi, a platform connecting DeFi projects with ethical hackers, is hosting a million-dollar attackathon. They also offer a diverse range of bug bounties, catering to projects of all sizes – from niche smart contracts to major DeFi protocols. Notably, ImmuneFi recently surpassed a significant milestone of $100 million paid out to bug hunters.
• Morpho’s Record-Breaking Bounty: To safeguard its $1.85 billion in locked value, Morpho, a lending pool aggregator, is offering a staggering $2.5 million bounty to anyone who can identify critical vulnerabilities in their system.
• Code Hawks’ Weekly Hacking Tournaments: Starting on July 4th, Code Hawks will launch a series of weekly hacking competitions targeting different DeFi platforms. Each competition will offer a dedicated bounty, with the first one focusing on TempleDAO and boasting a prize pool of $25,000 USDC.

The Future of DeFi Protocols Security:

The summer of 2024 is shaping up to be a pivotal moment for DeFi security. With a heightened awareness of security risks and a growing community of ethical hackers actively seeking vulnerabilities, DeFi protocols are receiving a much-needed security boost. However, the world of DeFi is constantly evolving, and the battle between attackers and defenders is likely to be a continuous struggle. As new DeFi applications emerge, developers and security researchers will need to work together to identify and mitigate potential security risks in order to ensure a safe and secure future for DeFi.
