Crypto-related exploits fell sharply in October 2025, with 15 major security incidents resulting in $18.18 million in losses. The figure marks an 85.7% decline from September’s $127.06 million, based on data compiled by PeckShield.
The largest single incidents in October ranged from $1.8 million to $11 million, indicating a month dominated by mid-sized exploits rather than outsized, protocol-threatening breaches. While the downturn is notable, the number of incidents underscores that security risks remain widespread across the digital asset ecosystem.
Month-over-month volatility in exploit totals is common, but the steep drop suggests fewer large vulnerabilities were successfully exploited in October. Market participants often watch these figures as a proxy for the evolving maturity of crypto security practices, code audits, and real-time monitoring across exchanges, wallets, and DeFi protocols.
As the industry enters the final months of the year, ongoing attention to smart contract auditing, multi-layer defenses, and incident response remains essential to reducing both the frequency and severity of hacks.
