Crypto Hacks Caused $75.87M in Total Losses During June 2026

• Crypto losses reached $75.87 million across 40 major security incidents during June 2026. 
• Cross‑chain bridges and DeFi protocols are still responsible for most of the losses.
• Humanity Protocol hack ($31M) accounts for over 40% of the month’s total crypto losses.

According to blockchain security firm PeckShield, the crypto industry lost approximately $75.87 million across 40 major security incidents during June 2026. 

While that’s down about 7% from May’s $81.7 million, hackers are still going after the same vulnerable targets. Cross‑chain bridges, DeFi protocols, smart contracts, and hacked admin accounts have suffered most of the losses.

Humanity Protocol Leads June Crypto Losses

The largest attack in June was against Humanity Protocol, which lost about $31 million, accounting for over 40% of the month’s total crypto losses. After the exploit, it was reported that the attackers quickly moved the stolen funds across several blockchains, including Bitcoin, Solana, Hyperliquid, and BNB Chain.

This is a common tactic amongst cybercriminals, since moving stolen crypto across different blockchains makes it much harder for investigators to track. The reason is that funds get split, bridged, swapped into other assets, and shuffled through decentralized services, often before anyone can freeze or recover them.

Interestingly, PechShield also reported that the Humanity Protocol attack could be connected to the KelpDAO hack (the largest DeFi hack of the year), considering the stolen funds have also been mixed with proceeds linked to the KelpDAO exploiter.

The second biggest June crypto hack was the Syscoin Bridge exploit, which resulted in the loss of $10M, followed by the JaredFromSubway.eth MEV (Maximal Extractable Value) bot, which led to roughly $7.5 million in damages. Unlike standard protocol hacks, this particular incident shows how attackers are now exploiting the system by manipulating transaction order and MEV, rather than finding vulnerabilities in smart contract code itself.

Bridge Protocols Remain Frequent Attack Targets

Bridge protocols continued to feature prominently among June’s security incidents. In addition to the Syscoin Bridge exploit, Aztec Bridge and Aztec Connect suffered combined losses of about $4 million, while Taiko Bridge lost approximately $1.7 million. The series of incidents shows that cross-chain bridge infrastructure remains a frequent target for attackers due to the large amounts of assets locked in these protocols and the complexity of their smart contract architecture.
