Crypto hacks in June resulted in $75.9 million in losses, with key incidents linked to North Korean hackers and flaws in validation mechanisms.
In June, the cryptocurrency sector faced a loss of around $75.9 million due to 40 significant hacking incidents, reflecting a 7.1% decrease from May’s total losses of $81.7 million, as reported by PeckShield.
The most substantial breach occurred at Humanity Protocol, where losses were reported at $31 million. However, a follow-up investigation by the protocol's team revised this estimate to approximately $36 million, attributing the breach to a compromised private key. Terence Kwok, the project founder, indicated that North Korean hackers might be involved, based on distinct indicators identified by experts.
Another notable incident involved an attack on Syscoin Bridge, resulting in a $10 million loss due to a flaw in the validation mechanism that allowed the creation of billions of unbacked SYS tokens.
According to PeckShield, an MEV bot linked to JaredFromSubway.eth was also hit, leading to a theft of $7.5 million. Other significant attacks included Secret Network, Polymarket users, SecondFi, and TESSERA, with losses ranging from $2.4 million to $4.67 million.
Outdated infrastructure also came under fire, with the Aztec Bridge suffering losses of $2.16 million and Aztec Connect losing $2.1 million, totaling about $4 million due to immutable contracts that the developers can no longer control.
Additional incidents included Taiko Bridge ($1.7 million), Token of Power ($1.58 million), Raydium ($1.34 million), and the LABUBU/OLPC pool on PancakeSwap ($1.1 million). PeckShield noted that the stolen funds from Humanity Protocol were laundered through various channels, including Bitcoin and Solana, and some were mixed with funds related to the KelpDAO exploit in April. It was suggested that the same parties may be responsible for both hacks.
Furthermore, the second quarter of 2026 set a new record for the cryptocurrency industry with 83 hacking incidents, leading to cumulative losses of $755.3 million, according to data from Unfolded.
