I'd expect a enemy state's ability to get information out of a system would in fact be correlated with insider's desires to chat about what they did at work. Find some bloke who is a bit lonely, a bit talkative and has good security access, send out a hot woman with an unexpected interest in military specifications. I'm no spymaster but that seems like something a spy agency could manage. Might be able to grab a stickynote with a few key passwords on it to sweeten the operation.
A hot woman with an unexpected interest in military specifications is unexpected and therefore suspicious. Their interest in the protagonist will be equally unexpected.
Some dudes on a forum about military games having an interest in the same? Totally normal.
Even better a woman who kinda looks like the target’s ex - a duper hot woman stands out and might activate the bloke’s memory of training. Spies whole thing is to blend in, appear unremarkable.
