Security Vulnerability in Verizon Call Filter App Exposes User Data

Source: Date:

Verizon users recently faced a major privacy breach due to a security vulnerability in the Call Filter app for iPhones and iOS devices. This glitch allowed unauthorized access to call history logs of Verizon users, raising concerns about real-time surveillance. The issue was identified by a security researcher who found that bad actors could obtain call logs without needing to hack into a phone or guess a password.

This vulnerability was not directly linked to Verizon, but rather to a third-party company, Cequint, which handles caller ID technology for the app. While Verizon has since fixed the issue, the incident highlights the risks associated with third-party data handling and the importance of robust security measures for user data.

Although Verizon claims that the flaw only impacted iOS devices and has been resolved, it serves as a reminder of the potential privacy risks in everyday phone usage.
