Cryptocurrency hacks and exploits drained $75.9 million across 40 incidents in June, marking a 7.1 percent decline from May's total, according to blockchain security firm PeckShield.
The Humanity Protocol exploit claimed the largest single loss at $31 million, representing roughly 41 percent of June's total theft. The remaining 39 incidents accounted for $44.9 million in combined losses.
PeckShield tracks confirmed on-chain theft and exploit activity. The data captures publicly documented cases where funds moved to attacker wallets, though the firm's methodology may exclude private settlement agreements, unreported incidents, or exploits still under investigation at the time of reporting.
The month-over-month decline suggests either a lull in large-scale attacks or a temporary shift in attacker focus. Without visibility into attack vectors, vulnerability timelines, or whether victims are raising defenses faster than new exploits emerge, the statistical drop alone provides limited insight into underlying security posture across the ecosystem.
June's list included smaller incidents typical of the monthly pattern: protocol bugs, smart contract vulnerabilities, and compromised infrastructure. The concentration of loss in a single incident (Humanity Protocol) underscores how one large breach can dominate monthly figures, while dozens of smaller failures accumulate beneath the headline.
