Crypto Security Incidents Surge: $700M Lost in Q3 2023
According to the quarterly report of blockchain security firm CertiK, the third quarter of 2023 was the “most financially damaging” quarter of the year, with almost $700 million in digital assets lost to various security incidents.
Within the report, CertiK highlighted 184 security incidents in July, August, and September 2023, with over $699 million in crypto assets lost during the quarter, surpassing the first- and second-quarter losses of $320 million and $310 million, respectively.
Private key compromises have been identified as the most costly exploit, costing over $204 million across 14 incidents. According to the report, the Multichain incident, in which the project’s CEO had exclusive control over private keys, resulted in a $125 million loss.
The incident demonstrated that centralized control of private keys for enterprises could result in a vulnerability, which in the case of Multichain led to the cessation of operations.
In addition to private key exploits, exit schemes and oracle manipulation were prevalent during the quarter. More than $55 million in digital assets were stolen in 93 exit fraud incidents during the quarter, according to the report.

In the meantime, 38 instances of Oracle manipulation stole over $16 million in cryptocurrency. The exploit of the cross-chain protocol Mixin Network contributed the most to September being the month with the highest number of crypto breaches in 2023.
