The Twitter thread doesn't seem to have any substantive information regarding a Signal "compromise." This looks like another rumor that doesn't have much basis.

The Twitter thread doesn't seem to have any substantive information regarding a Signal "compromise." This looks like another rumor that doesn't have much basis. The only known "compromise" that I can think of is specific iPhone/Android/desktop devices being compromised, leading to the compromise of all installed apps, including Signal; however, that would not be a Signal-specific compromise.
