My favorite author in that genre is Daniel Suarez, who makes some scarily accurate thrillers. It's not all 100% realistic, but as someone who is often annoyed at the deus ex machina[1] of other (science) fiction, this is really great. The author is a former software engineer, so I guess they know quite well how technology works in general.
