The bulletin warned of Russian professional hacking groups employing phishing scams to gain access to encrypted conversations, bypassing the end-to-end encryption the application uses.
A PHISHING SCAM .... meaning SOMEONE HAS TO RESPOND to something sent to them
Signal responded to the bulletin in a social media post Tuesday, saying the NSA's "memo used the term 'vulnerability' in relation to Signal-but it had nothing to do with Signal's core tech. It was warning against phishing scams targeting Signal users."
"Phishing isn't new, and it's not a flaw in our encryption or any of Signal's underlying technology," the company said. "Phishing attacks are a constant threat for popular apps and websites."
THERE IS NOTHING WRONG WITH SIGNAL
