I saw a bunch of headlines recently that said the FBI had decrypted one of the popular secure messaging apps (telegram or signal maybe?), which, bizarrely enough, fits my narrative perfectly. Though I saw other headlines stating that was incorrect reporting.
You probably saw the headlines about Cellebrite claiming to have "signal decryption" capabilities, which they did, provided they had the device in hand and unlocked
The company claiming to have broken Signal was simply pulling the database of messages off of an unlocked phone. It’s definitely not a hack and the blog post has since been heavily retracted.
