40% of crypto hack losses stem from private key theft

As crypto hacks continue to result in millions of dollars in damages, the theft of private keys has been identified as a primary cause. According to a report by DeFiLlama, crypto projects have lost a total of $16.69 billion to hacks to date. Approximately 40% of these losses stemmed from the leak or theft of private keys, rather than from smart contract vulnerabilities. In response, Web3 security firm CertiK noted that while attacks exploiting smart contract vulnerabilities are decreasing, hacks occurring during operational processes are on the rise. The firm suggested that as projects have focused their investments on smart contract security, other areas have become relatively more vulnerable.
