Wu Shuo learned that Syndicate posted on Twitter that Syndicate Labs experienced a security incident, with private key leakage leading attackers to maliciously upgrade bridge contracts on two chains, transferring approximately 18.5 million SYND and about 50,000 USD worth of customer tokens; affected parties will receive full compensation, with SYND holders also receiving additional compensation. Syndicate stated that the attack involved multi-stage reconnaissance, infrastructure mapping, vulnerability exploitation development, and precise execution, and has ruled out internal personnel involvement; it has added an extra encryption layer to developer keys and restricted access, plans to introduce hardware support or multi-signature support for upgrades, and has set up alerts and circuit breakers.
