Re: They admitted to it...
The hard part is how do you know that "Spazz69" is really a trader at Deutsche and not a kid in a basement, or a Russian bot, or an SEC agent ?
Pretty sure you'd use signal and confirm the contact personally when setting up using "Verify Safety Number" i.e. when you're out on the piss with the counterparty (at the start of the session for obvious reasons). At this point you're secure. If it changes you're alerted and you'd cease comms until re-confirmed.
