Hackers steal $351.6 million in Bitget crypto exchange hack

The Bitget breach highlights the critical risk of maintaining large balances in internet-connected hot and warm wallets, which are inherently more exposed to sophisticated attackers than cold storage. Suspected North Korean threat actors (likely Lazarus Group) have a well-documented history of targeting crypto exchanges, making them a known and persistent adversary that demands heightened defensive posture. The unauthorized transfers were caught by security monitoring systems, but not before hundreds of millions were exfiltrated, underscoring that detection alone is insufficient without equally rapid automated response and containment capabilities. Exchanges holding customer funds at scale must treat wallet architecture as a critical security control, not merely an operational convenience.
