The problems associated with the old numbers increase
Telecom companies do this without increasing the number chain. But this process is not safe for users who have previously had this. When your old number gets new users, data related to the old number becomes easier for new users to access. For this reason, it can put process users at risk for privacy and security.

Information about older users is stolen this way
Researchers at Princeton University in the US have made a big revelation that the entire process of telecom companies recycling old numbers raises questions about security and privacy. New users can access old user number information through recycled numbers. When you change your number, you immediately forget to update your new number on all digital accounts. For example, you are still using your old number in e-commerce applications.

The report stated that the journalist had taken a new mobile number, and then messages started coming in with blood tests and spa appointments. At the time of the research, 200 recycling numbers were tested per week, including 19 messages and calls from older users. Official messages and OTPs have also appeared in these numbers.

Detection of these threats
Researchers have listed 8 potential threats that could be caused by mobile number reuse. One major threat is that older users can be attacked by phishing. So the person who returns this number by recycling can also make phishing attacks via SMS. Cases of phishing attacks increase when messages seem trusted. Hackers can use these phone numbers to sign up for various alerts, newspapers, promotions and robocalls.
