November 2023 takes the title for 'most damaging' month with $363M in crypto stolen. Poloniex, HTX/Heco Bridge exploits & KyberSwap flash loan attack were the major players, says CertiK. #CryptoSecurity According to Cointelegraph.

The deployment of Api3 decentralized oracles natively on Unichain marks a critical security upgrade for the network's lending markets. Leveraging Unichain's sub-block architecture, asset prices are now updated faster than malicious actors can construct complex atomic exploits...

This flash loan attack analysis breaks down the complex strategies employed by exploiters in recent DeFi incidents, focusing on how arbitrage and oracle manipulation lead to massive losses.

Unleash DeFi's Full Potential: 3 Oracle Solutions That Will Revolutionize Your Security Now! Alright, let's talk about DeFi. It's the wild west, isn't it? A place brimming with innovation, financial freedom, and, let's be honest, a fair bit of risk. Especially when it comes to security. You’ve probably heard the horror stories – millions lost to flash loan attacks, smart contract exploits, or just plain old data manipulation.

The rapid growth of cross-chain transfers in decentralized finance (DEFI) has launched new opportunities for users, but has also introduced unprecedented risks. According to recent security analysis, flash loan attacks have become a major threat to bridge protocols, with billions of dollars being lost due to exploits within minutes of execution. Platforms such as Jumper replacement While positioning itself as a safer alternative for cross-chain operations, experts emphasize that the broader ecosystem still faces fundamental vulnerabilities that require urgent solutions.

Crypto hacks drained 3 8 billion from protocols and bridges in 2024 alone Oracle manipulation flash loan exploits and reentrancy bugs turned smart contracts into open vaults for attackers The Wormhole bridge lost 320 million to a signature verification bypass ...

**Abstract:** Decentralized Finance (DeFi) lending pools have demonstrated tremendous potential but remain vulnerable to flash loan attacks, oracle manipulation, and governance exploits. Traditional security measures often lack the ability to proactively identify and mitigate these evolving threats. This paper introduces a novel system leveraging Multi-Modal Graph Neural Networks (MM-GNN) to dynamically analyze on-chain activity, smart contract code, and real-time market data to detect anomalous behavior indicative of malicious intent within DeFi lending protocols.

**Abstract:** Decentralized finance (DeFi) lending pools operating across multiple blockchain networks introduce unique governance and regulatory challenges. This paper proposes a novel system leveraging hypergraph analysis and reinforcement learning to proactively detect anomalous activity and enforce predefined governance rules across these cross-chain environments. Our system, “HyperGuardian,” identifies subtle, interconnected patterns indicative of potential exploits, flash loan attacks, or regulatory breaches, significantly improving the security and compliance posture of cross-chain DeFi lending protocols.

On May 13, 2026 at 23:22:02 UTC (BNB Chain block `98134017`), attacker EOA `0xcb26b3a469c5aee911d059a25de2b26ed52826e9` executed transaction `0x2fdd6aef515fb06ce803c55086bb71de712631979809c135cf6d02be133f5cdb`, which deployed bootstrap contract `0x8aa9cb61885121448f1bf9a5df80ec36c6fbd535` and exe...

The attacker used a Balancer V2 flash loan to pre-fund the treasury, then called `claimPayroll(3)` from an attacker-controlled contract that passed address-only claim authorization and triggered the treasury transfer path.

In one of 2025’s most audacious crypto exploits, hackers drained $42 million from GMX Arbitrum-based liquidity pool. The attack, which occurred in broad daylight, leveraged flash loans to manipulate mint-and-redeem mechanisms inside GMX’s GLP pool, allowing attackers to extract millions in real assets including ETH, LINK, UNI, DAI, and USDC. GMX missed the specific logic vulnerability […] The post Crypto Bloodbath: $42M Stolen in GMX Flash Loan Raid appeared first on TechJuice.
