Security firm Hacken reports that crypto related thefts have totaled more than $3.1 billion globally in just the first half of 2025. Despite increased scrutiny, vulnerabilities persist in smart contracts, front end interfaces, and operator keys leading to high profile breaches and exploit events.
Hacken’s report shows smart contract flaws caused $1.6 billion in losses, while phishing and admin credential theft accounted for $800 million. Front end skimming, where user sessions are manipulated to drain funds, was responsible for another $400 million. The remaining losses stem from exchange and bridge hacks tied to misconfigured wallets or human error.
DeFi protocols remain hotspots. Core developer teams are urged to adopt third party audits, implement multisignature custody, and enforce bug bounty programs. Even so, new vulnerabilities emerge as platforms scale. Hacken warns that unchecked growth and incentive misalignment may fuel further breaches unless security standards become the priority.
