Lazarus at BitoPro: Exploiting Crypto Exchange Upgrades for Maximum Impact
When Taiwan’s BitoPro cryptocurrency exchange disclosed in mid-2025 that it had been struck by a devastating theft of $XX million in digital assets, the familiar name that surfaced behind the breach was Lazarus Group — North Korea’s most prolific and adaptable state-aligned hacking unit.
