An information security agency recently reminded that because some of the original users' online accounts can be accessed through the mobile phone number verification function, the cancelled and resold mobile phone numbers have security risks.

Operators will recycle the deactivated and abandoned mobile phone numbers, "freeze" them for a period of time and then resell them, which is conducive to making full use of telecom number resources. But nowadays, whether it is social account or online payment, binding mobile phone number and SMS verification has become a common way to ensure account security.

If we don't face up to this situation and leave some numbers in a state of "poisoning", the "old numbers" will breed "new risks". Earlier, the police cracked a case of using the resold mobile phone number to steal the funds of the former owner Alipay account.

It is unrealistic to eliminate hidden dangers only by one operator, which requires the joint efforts of all parties. Mobile phone users themselves must enhance their risk awareness, unbind relevant software and change their mobile phone numbers in time.
