Hack3d: Web3 Security Report 2023, Crypto Hacks and Scams Cost $429.7 Million

The year 2023 was a turbulent one for the web3 sector, as cybercriminals exploited various vulnerabilities and loopholes to steal a staggering $429.7 million worth of crypto assets from users and platforms.

This is according to a comprehensive report by Certik, a leading blockchain security firm, that analyzed over 50 incidents of crypto hacks, scams, and exploits that occurred in 2023.

The report, titled “Hack3d: The Web3 Security Report 2023”, revealed that the majority of the losses were caused by smart contract exploits, which accounted for $145 million, or 34% of the total.

These exploits involved manipulating the logic or parameters of smart contracts to drain funds from protocols, often using flash loans or arbitrage bots.
