Binance and Kraken Prevent Social Engineering Attacks Without Data Loss
Binance and Kraken faced social engineering attacks aimed at customer support agents, similar to a recent breach at Coinbase. Hackers attempted bribery and provided instructions for contacting attackers via Telegram. Both exchanges successfully blocked these attempts without any data breaches.
Coinbase revealed it expects $180 million to $400 million in costs from a breach where attackers accessed personal information after bribing employees. This incident resulted in a $20 million ransom demand and the firing of involved staff.
At Binance, AI systems identified bribery-related messages, preventing escalation. Access policies limiting customer data exposure also reduced risks. Coinbase had been monitoring unusual activity since January, with warnings from other exchanges about threats targeting its clients.
