Phone Number Data Leak
Have you ever thought that what happens to that old number when you change your phone number and take a new number instead of the old number? Mobile carriers often recycle that old number and give you a new number instead. But for many users, this process is not safe. When your old number is given to a new user, then the data of your old number becomes accessible to that user.
In such a situation, the privacy of users is in danger. Researchers at Princeton University have told in their new report that your privacy can be threatened by your old number. When you change your number, you forget to update that number in your digital accounts. That is, on e-commerce applications, you are using it from the old number itself, in many apps as well. In such a situation, you forget to update them with a new number.
University said that, as soon as a journalist got a new number, his phone started receiving blood test results and lots of text of spa appointments. A researcher named Arvind told that, we used 200 recycling numbers for a week and found that 19 numbers were still receiving security, privacy related calls and messages. That is, the new users were getting all this information.
Researchers mention 8 dangers related to recycling here. The biggest danger in this is the theft of your data. That is, as soon as your old number is given to the new subscriber, then his information can be obtained through SMS. Subscribers will get caught in the trap after seeing many such messages and will believe. At the same time, the attacker can use your old number anywhere in login or newsletters, while he can start many SMS services.
Researchers said that, there are many such telecom companies in America, who have not taken any necessary steps in this matter so far.
