Zaif reported a breach in which attackers stole cryptocurrency from both user hot wallets and the exchange’s own assets, with losses described as about US$59 million. Sentinel Protocol’s investigation centered on three reported attacker-controlled wallet addresses for Bitcoin, MonaCoin, and Bitcoin Cash, including 5,966 BTC, 6,236,810 MONA, and 42,327 BCH. The response focused on validating the wallet balances, tracking token movement, and blacklisting confirmed malicious addresses in Sentinel Protocol’s Threat Reputation Database. The source highlights the importance of rapid wallet-tracing and exchange-side blocking to reduce laundering opportunities after cryptocurrency theft.
