Bithumb Hack

Bithumb suffered an insider attack leading to abnormal withdrawals but managed to recover approximately $14m.

Bithumb detected unusual withdrawals through their monitoring system. The incident was an "accident involving insiders." The exchange's EOS hot wallet began sending EOS to the attacker's address. The company realized the attack was ongoing and started to move the funds to the cold storage wallet, which was not compromised.

Bithumb admitted that it had only focused on protection from outside attacks and did not verify its staff.
