Hello you guys,
I'm very afraid to say that I comitted a very blatant OPSEC mistake today.
I occasionally leave my phone left unattended for a couple of minutes at my desk at work, which I usually do not worry about too much (which some of you might rightfully think is a mistake in itself).
But today I must have missed the lock button or something, so I left it both unattended and unlocked for a couple of minutes. I was wondering whether or not there is a way to double check the phone's activity during that time period.
All in all, it was in exactly the place I left it, nothing seemed out of the ordinary and I have decent enough trust in my coworkers, so even if there is no such option, I think I'm in the clear.
But as the saying goes, trust but verify. :)
In any case, lesson learned and I will check twice before leaving my phone at my desk from now on...
