A network tampering activity implemented by a popular Internet Service Provider (ISP) and in development by another has come under some scrutiny.
Verizon has been quietly tracking the Internet activity of more than 100 million cellular customers by inserting “supercookies” into their cell phone web browsing — powerful markers that even sophisticated users find it difficult to evade. The tracker functions even if a customer uses a private browsing mode or clears cookies. Privacy advocates say this tracking can expose our Internet behavior to outsiders, including to government intelligence services, and also may violate federal telecommunications and wiretapping laws. (AT&T’s program is not as sophisticated, and is still being developed and tested, so is not yet being deployed.)
