A few things point to it:
* He thinks Moldova is part of Romania. That is a contentious issue. He mentioned it specifically. To do so, they'd have to care about it a bit. Doesn't like the Russians it seems, that hints to it as well.
* He listed possibilities about how someone could be a hacker not just be part of the Russian FSB -- working for a multi-national IT company.
* Age based on what he considers are typical "cool" role models for this age. He listed Rambo and Terminator -- those were the typical boys' role models growing up in the early 90s in Eastern Europe (especially ex-Soviet Union).
* Cares and knows about DNC and specific candidates. Guessing they are following the election process, so probably live in US or Canada.
