CertiK's annual report, released on January 3rd, provides an in-depth analysis of the state of security in the Web3 space over the past year.
A key finding of the report was the third quarter of 2023, which saw the highest losses, totaling over $686 million. The report also pointed out that incidents involving private key compromises were particularly costly, resulting in losses of over $880 million across 47 incidents.
When analyzing losses by blockchain, Ethereum topped the list with $686 million lost in 224 incidents, averaging $3 million per incident. BNB Chain, despite having a higher number of incidents at 387, reported significantly lower total losses of $134 million.
The report also highlighted the challenges of cross-chain interoperability, which contributed to nearly $800 million in losses due to breaches across multiple blockchains.
Ronghui Gu, CertiK's co-founder, calls the reduction in losses a "positive development" for blockchain security. He attributed this improvement to the increasing adoption of proactive security measures, such as bug bounty platforms, and expressed optimism for a continued downward trend in losses into 2024.
Additionally, Gu noted that the decline in losses could be partly due to the broader bear market, which saw a decrease in token and treasury valuations. He believes that sustained low loss levels during a bull market would further confirm that the Web3 industry is effectively learning and implementing security lessons.
The 2023 CertiK report reveals a promising decline in crypto hack losses, indicating significant advancements in blockchain security and a maturing industry poised for increased resilience against cyber threats.
