SIGNAL OPSEC FAIL
Signal, the privacy-focused messaging app that boasts about its security features, has been a favorite go-to for anti-ICE in Minneapolis as a means to communicate and coordinate their operations.
Using the command-line version of the Signal app (Signal-cli), anything posted in the group after it joins can be seen in plain text on that computer — useful for bots, backups, monitoring, logging, archiving, or quietly watching group chats without anyone noticing an extra person joined. Signal-cli allows:
• phone #’s to leak
• view deleted messages
• view edited messages
• see who emoji reacted to a message
• see when someone opens up the group chat on their phone (server ping)
• see when typing start/stop
• Timestamps for everything mentioned above
Signal has been a Godsend for research and hunting down anti-government extremists.
