Cosmos Labs admits it wrongly cleared bug behind $5.7 million six-chain hack

Cosmos Labs has admitted it wrongly declared a bug fixed — the same flaw was later exploited in a six-chain hack stealing $5.7 million. MANTRA Chain, which lost $3.6 million, says the patch was released only 20 hours before the attack and did not identify what it fixed. The incident exposes major security coordination failures in the Cosmos ecosystem.
