The largest incident of the month was the hack of Humanity Protocol, resulting in losses of $31 million. Following an investigation, the protocol team estimated the damage closer to $36 million, as reported by The Block. Project founder Terence Kwok linked the breach to the compromise of a private key. Experts from Quantstamp suggested that North Korean hackers might be involved, citing several characteristic signs.

The second-largest incident involved an attack on Syscoin Bridge, leading to losses of $10 million. A validation mechanism error allowed the attacker to issue billions of unbacked SYS tokens without proper burning, according to the company.

PeckShield also noted the hack of an MEV bot associated with the address JaredFromSubway.eth, resulting in losses of $7.5 million.

Among the significant incidents in June, the company included Secret Network, Polymarket users, SecondFi, and TESSERA, with losses ranging from $2.4 million to $4.67 million.

Additionally, PeckShield highlighted two attacks on the outdated infrastructure of Aztec. The damage to Aztec Bridge was estimated at $2.16 million, while Aztec Connect suffered losses of $2.1 million, totaling around $4 million. These involved immutable contracts over which developers no longer have control and cannot pause.

The top 10 incidents in June also 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).

According to PeckShield, the funds stolen from Humanity Protocol were laundered through Bitcoin, Solana, Hyperliquid, and BNB Chain. Some assets were mixed with funds related to the April KelpDAO exploit. The company suggested that the same participant might be behind both attacks.

It is worth noting that in the second quarter of 2026, the industry set a record for the number of hacks, with 83 incidents. The total damage amounted to $755.3 million, as calculated by Unfolded.
