币界网报道：Private key compromises and front-end exploits emerged as the leading causes of cryptocurrency thefts in 2025, according to recent security analyses. Hackers increasingly targeted weak private key storage practices, exploiting poorly secured wallets and phishing attacks to gain unauthorized access. Front-end vulnerabilities, particularly in decentralized applications (dApps), allowed attackers to manipulate user interfaces and redirect funds. The most notable incidents involved sophisticated social engineering tactics that tricked users into approving malicious transactions. Security experts emphasized the need for multi-signature wallets, hardware storage solutions, and enhanced smart contract audits to mitigate risks. The report also highlighted a concerning rise in attacks targeting cross-chain bridges, though private key and front-end breaches accounted for over 60% of total losses. Major blockchain networks implemented urgent protocol upgrades following these findings, while exchanges strengthened their monitoring systems for suspicious withdrawal patterns.
