Crypto security incidents in October lead to $129M in losses: CertiK

Security incidents like exit scams, flash loan attacks and exploits pushed crypto losses in October to $129.6 million. 

According to data compiled by blockchain security firm CertiK, exit scams led to $1.2 million in losses, while flash loan attacks caused $1.5 million in crypto losses. Meanwhile, exploits accounted for the most losses, with $127 million lost to exploits. 

The biggest incident in October involves the Radiant Capital, a lending protocol that lost over $50 million last month. Furthermore, a $36-million phishing attack on a whale took second place on the list, while the $13-million hack on the crypto exchange M2 took third place. 

The $127 million losses in October represent a 2.91% month-on-month increase compared to September’s $123.4 million. However, it also marks a 60% decline from the $324.7 million lost to exploits in May 2024. 

Largest crypto security incidents in October

The biggest incident in October involves the lending protocol Radiant Capital. On Oct. 16, the lending protocol halted its markets after a breach on its BNB Chain and Arbitrum markets. A hacker could access the protocol’s private keys and smart contracts, draining over $50 million in digital assets. 

The team behind the protocol said in a post-mortem that the hackers accessed the devices of at least three of its core developers through a malware injection. 

On Nov. 1, the Radiant Capital said that it resumed its Ethereum lending markets after the hack. The protocol announced that it had implemented changes to its security mechanisms. 

According to Radiant Capital, it transferred the protocol ownership into a timelock contract. This enforces a mandatory 72-hour waiting period for any adjustments, strengthening the security. 

Apart from Radiant Capital, a crypto user lost millions to an exploit. On Oct. 11, a crypto wallet lost 15,079 fwDETH, worth about $36 million, after signing a phishing transaction.
