The FBI uncovered a plot to attack the White House after suspects discussed their plans on an encrypted network, known for its high level of security, and cybersecurity experts shared insights into encryption and its potential weaknesses.

According to a criminal complaint, the group of about 20 people called themselves the “Vanguard of the old” with communications starting in March via TikTok.

Some of the members later moved to Signal, an app that uses end-to-end encryption for its messaging and calling services, through a primary chat of “approximately 19 individuals” and smaller side chats, authorities said.

Scott Phillips, vice president of engineering at Nexigen, a cybersecurity company in Newport, said, “A lot of places are messaging providers are going towards end-to-end encryption because it preserves privacy for the end user.”

Phillips added, “The whole point of end-to-end encryption is that only at the endpoints does it get decrypted. Everybody in the middle has no idea what’s said, what’s being written, even if they logged it. All they have is garbage.”
