A series of exploits struck cross-chain infrastructure within hours of each other, exposing recurring weaknesses in how protocols manage administrative access and validate transactions. The attacks targeted Verus, B² Network and other systems that connect Bitcoin and Ethereum, resulting in roughly $35 million in combined losses. According to reports, the breaches stemmed from compromised private keys, misused upgrade permissions and flawed validation checks rather than any failure of the underlying cryptography. The pattern highlights a persistent vulnerability in bridge and cross-chain designs, where centralized control points and privileged functions can allow attackers to drain funds without cracking the encryption itself. The near-simultaneous timing of the incidents raised concerns about whether the events were coordinated or reflected shared design flaws across multiple platforms. The episode adds to a long record of cross-chain systems being a favored target for exploiters.
