Crypto Exploits Hit $75.8M in June as Humanity Protocol Attack Leads Monthly Losses

Highlights:

• PeckShieldAlert has reported that traders lost roughly $75.8 million from crypto hacks last month.
• Humanity Protocol suffered the highest loss, worth approximately $31 million
• The leading causes of security compromise last month include losses from third parties, DeFi, and bridge attacks.

Last month, hackers stole $75.87 million, as crypto-related losses dropped 7.13% month-over-month, according to PeckShieldAlert. Notably, the attack on Humanity Protocol was the largest hack incident in June, resulting in losses worth roughly $31 million. So far, the attacker behind the Humanity Protocol exploit has been moving the stolen funds across several blockchain networks, including Bitcoin (BTC), Solana (SOL), Hyperliquid (HYPE), and Binance Coin (BNB). 

PeckshieldAlert noted that some of the funds were mixed with assets connected to the KelpDAO exploit. This has raised concerns that the same group of attackers may be linked to both incidents. Bridge attacks also accounted for a major portion of the losses last month. For example, Syscoin Bridge suffered an estimated $10 million loss, while Aztec Bridge and Aztec Connect suffered combined losses of approximately $4 million.

#PeckShieldAlert In June 2026, the crypto space experienced 40 major hacks, resulting in total losses of $75.87M — a 7.13% month-over-month decrease from May ($81.7M).

Both #Aztec Bridge & #Aztec Connect were targeted within the same month, with combined losses of ~$4M.

Other Major Hack Incidents Recorded in June

Another major crypto exploit last month involved an MEV bot attack linked to JaredFromSubway.eth. It resulted in losses worth approximately $7.5 million. Secret Network users lost roughly $4.67 million, while Polymarket users were affected by a $3 million security incident. 

Additional attacks reported by PeckShieldAlert involved SecondFi and TESSERA. Each of these platforms lost roughly $2.4 million. Taiko Bridge, an Ethereum Layer-2 network, also suffered losses worth roughly $1.7 million. Token of powers lost approximately $1.58 million, Raydium forfeited about $1.34 million, while LABUBU/OLPC lost about $1.1 million. 

Certik Alert Reports Higher Losses from Crypto Exploits

A separate report from Certik Alert, another blockchain security firm, paints a broader picture of the hack incidents last month. While PeckshieldAlert reported 40 major hacks totalling $75.87 million, Certik Alert reported 67 security incidents resulting in losses worth $81.7 million. Certik Alert’s account included losses attributed to phishing attacks. “With 67 incidents recorded, June has the highest number of incidents since the beginning of 2026,” the blockchain security firm stated.

Unlike PeckShield, Certik Alert categorized the different hack incidents last month. Wallet compromise scams topped the list, as they resulted in losses worth roughly $35.95 million. Code vulnerability followed closely at $19.73 million. Others include phishing, Honeypot, and Frontend, with losses worth approximately $12.79 million, $7.47 million, and $3.05 million, respectively. 

Under incident losses by type, third-party tools accounted for a larger share, with losses worth approximately $32.96 million. Decentralized Finance (DeFi) followed closely, accounting for $14.04 million in losses last month. Bridge, Layer 2, and Meme also contributed significantly to the losses in June. Scammers exploited them to steal $6.47 million, $4.4 million, and $1.7 million, respectively.

Overall, the reported figures highlight growing concerns as crypto platforms continue to face risks from exploits targeting bridges, protocols, and user funds. Although the total losses reported last month were lower than the figure reported in May, attackers have continued to seek new means of moving stolen assets across different networks, making security a growing focus for blockchain projects.

On May 27, Crypto2Community reported that OpenZeppelin co-founder Michael Aráoz warned users to exit DeFi positions as he now considers all of them unsafe after repeated crypto exploits.
