Amnesty has awarded Facebook’s WhatsApp and Messenger apps the top spot in a new privacy ranking for messaging services.
The human rights NGO gave the two services a combined score of 73/100, with Apple’s iMessage and Facetime, and Telegram coming in 2nd with 67.
But it criticized Facebook for failing to set end-to-end encryption as the default option on Messenger and not highlighting the risks of less secure messaging.
For years, WhatsApp has set the standard for secure, private messaging. End-to-end encryption is the default setting, and it can’t be turned off.
But when Facebook introduced end-to-end encryption to Messenger earlier this year, it was criticized by privacy advocates for making it opt-in.
That means that only messages and photos sent through a “Secret Conversation” are properly encrypted.
Other messages, meanwhile, are sent via Transport Layer Security, meaning the messages are encrypted between the user and Facebook.
But crucially, Facebook can decrypt these message if it needs to – if, for example, the FBI comes knocking.
In its report, Amnesty quotes the Electronic Frontier Foundation’s senior attorney Nate Cardozo: “The fact that it is not on by default means that Messenger can’t and shouldn’t be treated as a secure platform.
