What’s the state of crypto hacks in 2025?
Crypto attacks have surged; August recorded $163 million stolen (a 15% increase), bringing 2025 losses above $2.5 billion.

A crypto phishing scam tricks users into signing malicious transactions or approvals that grant attackers token transfer rights. Attackers typically use lookalike interfaces or deceptive links; once a signature is granted, funds or allowances can be moved without further confirmation.
The victim interacted with a fraudulent link and approved a contract signature that requested broad token allowances. The attacker immediately moved approximately $4.3M in staked ETH and $2.2M in wrapped BTC. On-chain monitoring revealed fast distribution across multiple addresses and mixing services.
Greater DeFi complexity and more frequent third-party approvals expand attack surface. In August 2025, Web3 security monitors recorded about $163 million stolen across ~16 major incidents—up 15% from July—pushing total 2025 losses above $2.5 billion. The February $1.5B Bybit incident remains the largest single event this year.
