According to reports, the hack took advantage of systems built by ISPs like Verizon, AT&T, and Lumen Technologies (formerly CenturyLink) to give law enforcement and intelligence agencies access to the ISPs’ user data.

In 2004, the government dramatically expanded this wiretap mandate to include internet access providers. EFF opposed this expansion and explained the perils of wiretapping the internet.

The internet is different from the phone system in critical ways, making it more vulnerable. The internet is open and ever-changing. “Many of the technologies currently used to create wiretap-friendly computer networks make the people on those networks more pregnable to attackers who want to steal their data or personal information,” EFF wrote, nearly 20 years ago.
