A study from the Department of Computer Science and Center for Information Technology Policy at Princeton University draws attention to security and privacy risks that stem from recycling mobile phone numbers.
Researchers point out how threat actors can abuse this practice to carry out account takeover, phishing and spam attacks or restrict targets from signing up to online platforms.
The study examined 259 phone numbers available for new subscribers at two major carriers in the US. The findings show that 66% of the mobile phone numbers (171) were still linked to various online platforms, making them susceptible to account hijacking.
