World's top messaging app officially banned for House lawmakers

Lawmakers in the House of Representatives are no longer allowed to use the world's top messaging app after a review discovered it is a high risk to users.

A memo sent to all House lawmakers on Monday was issued just days after the U.S. bombed three nuclear facilities in Iran. Some security experts have suggested that the move has increased the chances of cyberattacks in the United States.

"Office of Cybersecurity has deemed WhatsApp a high risk to users due to the lack of transparency in how it protects user data, absence of stored data encryption, and potential security risks involved with its use," the memo reads in part.

This is not the first time that the House of Representatives has prohibited lawmakers from having certain apps on their electronic devices. In 2022, the House prohibited members from downloading TikTok because of numerous security concerns. That ban followed from the $1.6 trillion spending package that prohibited all federal devices from having the app.

"With the passage of the Omnibus that banned TikTok on executive branch devices, the [Chief Administrative Officer] worked with the Committee on House Administration to implement a similar policy for the House," a spokesperson for the House Chief Administrative Officer told Reuters at the time.

The CAO said lawmakers should instead use other messaging platforms such as Microsoft Teams, Signal, Apple's iMessage and FaceTime, and Amazon's Wickr platform.
