【A fraudster wearing a rubber mask impersonated a CEX user for video verification and failed to hijack their account】CEX recently stated that they have discovered that a fraudster wearing a Halloween-style rubber mask attempted to deceive their staff, but was unsuccessful. It is reported that when users try to regain access to their CEX accounts, they may be asked to have a video call with a support agent to verify their identity. The attacker showed some dangerous signals in the first round of checks, such as failing to mention the asset names held in the account. These signals led the agent in charge to request a video call to grant access to the account. During the call, the CEX staff asked some questions and checked the person's ID, and the attacker exposed suspicious circumstances at this stage. CEX Chief Security Officer Nick Percoco said that some exchanges do not follow the details as much as CEX requires of its team, and some companies support outsourcing, which is more likely to cause issues.
