>>5616051>>5616061>>5616074>hard realism, spy fi, espionage fictionA lot of intelligence gathering is open source, literally wikipedia what is the capital of Iran lol, some people claim this is 80-90% of intelligence.
Another technique commonly used in the US is a compilation method I believe called All Source Fusion. It sounds a bit similar to the Mosaic Theory in investment research lol, but basically compiling and corroborating across many varied sources open and clandestine, HUMINT, SIGINT, ELINT, IMINT etc. Maybe it is like those academic papers that summarise hundreds / thousands of other papers research findings to establish a comprehensive picture. I believe All Source Fusion and various likelihood assessments are made to attentuate the effects of targeted counterintelligence poisoning information gathering. The ultimate aim of intelligence is to insert yourself invisibly into the opponents OODA loop, decisionmaking etc.
Another interesting angle to explore is the heavy use of third party contractors. Take a look at the 10-Ks of BAH, PLTR etc lol. Or maybe something like Hakluyt hehe. I was actually quite impressed I think there was some Delta Green supplement dedicated to this (I have not read this lore book though) that directly cited BAH lol
The gentleman I met was Nigel Inkster. He must have been a very good spy, because I remember nothing of what he told me during the meeting. I tried to ask him about ETERNALBLUE and DOUBLEPULSAR, they were in the news at the time, I think one of those vulns affected WPP. In fact I believe Nigel Inkster actually conveyed negative information, he somehow extracted knowledge out of my head, I actually left the meeting feeling more stupid and knowing much less than I did before.
