Gnosis Pay, TesseraDAO Lose $2.5M in June Cross-Chain Hacks

- Early June 2026 attacks expose AI-assisted vulnerabilities and growing security risks - Experts urge DeFi teams to enhance defenses amid rising exploit trends On June 2, 2026, Cryptopolitan reported that Gnosis Pay and TesseraDAO suffered major cross-chain attacks, and the projects collectively lost $2.5 million in early June. According to Cryptopolitan on June 2, 2026, Gnosis Pay was compromised through a bug in its delay module, and the flaw allowed an intruder to bypass safeguards and trigger unauthorized transactions. As a result, the company advised users to withdraw funds and pledged to cover losses, and it also asked bridge validators to pause activity to contain the breach. Cryptopolitan further reported on June 2, 2026, that TesseraDAO lost $2.5 million in a “mint-and-dump” exploit. An attacker minted 99 million TSR tokens on BNB Chain and exchanged them for USDT, causing a price collapse, and the attacker then laundered the funds via Tornado Cash. According to security firm PeckShield on June 2, 2026, fourteen major cross-chain exploits had already occurred in 2026, and these incidents totaled $340.7 million in losses from bridging protocols. In addition, experts, including OpenZeppelin’s Manuel Araoz, noted that attackers using AI tools now outpace human defenders in finding vulnerabilities, while SlowMist’s founder and others urge DeFi teams to deploy AI for defensive testing and regular attack simulations. Therefore, they emphasize an urgent need for improved security practices in the sector. As of June 2, 2026, at 12:09 UTC, Tether USDt (USDT) was trading at $0.999, down 0.014% in 24-hour volume.
