The Ministry of National Security posted an article on its WeChat account. Recently, a reminder to “be silent for three seconds when you receive a strange call” went viral on social platforms. The reminder points out that after connecting to the victim's phone, criminals may deliberately keep silent and induce the victim to respond, such as “hey” or “who.” Voice samples of just a few seconds may be used by criminals for AI voiceprint cloning, and then impersonate identities to commit illegal and criminal acts such as fraud. Therefore, when answering a call, you can first be silent for three seconds. If the other person continues to be silent, hang up immediately. This reminder is a wake-up call for bioinformation security.
