Former NSA whistleblower Edward Snowden, who warned people in July this year about government agencies using military-grade spyware to keep tabs on them, has now urged them not to not use the services of ExpressVPN. 

“If you’re an ExpressVPN customer, you shouldn’t be,” he tweeted. Snowden also shared a tweet from Joseph Menn, a cybersecurity investigative reporter, who spoke about the Chief Information Officer (CIO) of ExpressVPN being one of three former U.S. intelligence officers who agreed not to fight accusations of aiding UAE hacking. people.

ExpressVPN did not respond to Snowden, but said in a statement that they knew “the key facts” relating to the employment history of their CIO Daniel Gericke. “In fact, it is his history and expertise that has made him an invaluable hire in our mission of protecting user privacy and security,” the company said.

A virtual private network (VPN) mimics a private network on a public network. It offers users online privacy by hiding their Internet Protocol (IP) address so that their online actions are virtually untraceable. It also protects against eavesdropping while sending emails, shopping online or paying bills.

Earlier this week, the US Department of Justice revealed in court records that ExpressVPN’s Gericke and two others were working on Project Raven, a surveillance operation for the UAE government that involved hacking personalities and heads of state. ExpressVPN is one of the largest VPN service providers in the world.

In a blog post in July, Snowden warned that smartphones had become the “most dangerous” things we owned. He had also tweeted about the Pegasus software scandal about how software developed by Israeli startup NSO Group was helping government agencies around the world spy on citizens’ cell phones.

Snowden revealed secret documents in 2013 that provided a public window into the covert mass surveillance capabilities of the U.S. intelligence agency NSA and its international partners.
