Regin: Top-tier espionage tool enables stealthy surveillance
The list of infected countries might tell us a thing about the attacker:Russia and Saudi Arabia at the top: classical US intelligence targets.
Pakistan and Afghanistan: Likely anti-islamists effort.
Austria, Belgium, Iran: Opec, IEAE, tons of EU-institutions - someone who wants better intel about the nuclear talks with Iran?Ireland, Mexico, India: Hard to find political reasons for those countries, but if you look at it economically: Ireland is the main hub for US companies into the EU, Mexico is a neighbouring country to the US, India: rival to ChinaMy totally far-fetched guess would be that this trojan comes from the NSA or the GCHQ, I don't see China caring that much about Saudi Arabia and AfPak.
