June 2026: A wave of crypto project hacks — more than 20 incidents in one month
In June 2026, the cryptocurrency industry faced a record wave of cyberattacks. According to my data, more than 20 hacks of various crypto projects have been recorded since the beginning of the month. The latest high-profile incident involved the Taiko project, which lost approximately $1.7 million due to a vulnerability in the network state verification mechanism.
Attack on Taiko: Details and Consequences
Taiko is an Ethereum-compatible rollup that finalizes transactions on the main network. In the morning, security experts from Blockaid published a warning about an ongoing attack. Taiko representatives confirmed the incident and stated that the platform's bridges are no longer secure.
According to data from the analytical platform Lookonchain, the hacker has already begun withdrawing funds. From the attacker's wallet, 1.99 million TAIKO tokens (approximately $189,000) were sent to the MEXC exchange. The address still holds 870.8 ETH — nearly $1.52 million.
The Taiko team is working together with the Security Council and ecosystem partners to contain the incident. The company also does not rule out technical and legal measures against the hacker. Developers have asked centralized exchanges to freeze deposits of TAIKO tokens until further notice.
The project has published four attacker addresses for tracking fund movements. The fate of the stolen assets largely depends on how quickly crypto exchanges can block the flagged wallets.
Bridges — The Achilles' Heel of the Industry
Bridges have traditionally been considered one of the most costly vulnerabilities in the cryptocurrency industry, and 2026 is no exception. According to DefiLlama, more than 20 hacks of crypto projects have been recorded in the sector since the beginning of June. This is an alarming signal for the entire market.
My analysis: The current situation demonstrates that the security of cross-chain bridges remains a critical issue. Investors should temporarily avoid using untested bridges and closely monitor security updates from projects. The market clearly needs stricter audit standards and rapid incident response mechanisms.
