Crypto exploits in 2025 have already topped $2.5 billion — and the story isn’t just about buggy smart contracts anymore. New industry data from Sentora and Chainalysis shows a clear shift: attackers are increasingly targeting people and privileged access rather than just code.
Big picture numbers
- Sentora’s “Total TVL of Exploits 2025” data shows more than $2.53 billion in losses tied specifically to protocol and platform exploits so far this year.
- Broader industry estimates compiled by Chainalysis put total crypto theft across all categories between $2.7 billion and $3.4 billion in 2025.
Social engineering now leads exploit value
- Social engineering is responsible for the lion’s share of exploit-related losses, accounting for 55.3% of the total — roughly $1.39 billion.
- Private key compromises (via phishing, malware, poor credential handling, etc.) made up about 15% of exploit losses, or roughly $370 million.
- The remaining losses were attributable to other methods such as infinite-mint attacks and traditional smart contract vulnerabilities.
Why the shift matters
Security experts point to improving tooling — automated audits, formal verification, and other protocol-safety measures — that have reduced the frequency of large smart-contract bugs. As those defenses mature, attackers are pivoting toward lower-tech but highly effective strategies that exploit users and insiders: social engineering, credential theft, and attacks on custodial operations.
State-backed actors and high-profile heists
Chainalysis identified North Korea–linked groups as the single most prolific threat this year, tracing at least $2.02 billion in stolen crypto to DPRK-affiliated actors — a roughly 51% increase over 2024. A major factor was a record-setting Bybit exploit, where attackers are estimated to have taken about $1.4 billion.
Personal wallets rise, but institutional hits remain costly
Chainalysis also documented a sharp uptick in personal wallet thefts in 2025, affecting thousands of individual users. Those incidents tend to be smaller per case than large institutional breaches, but the increased frequency underscores the human-targeted trend.
What this means for defenses
The data suggests defending crypto assets in 2025 is as much about people and processes as it is about code. Key priorities: stronger user security practices, better key management, hardened operational hygiene at exchanges and custodians, and improved access controls for privileged accounts.
