"The general consensus among security experts and government agencies is that North Korea was behind the WannaCrypt attack"
Security experts (who?)
Government agencies (which ones?)
These phrases like "general consensus" without actually defining who they're talking about, is a bit like saying "international community" where really they just mean USA and UK, is just Orwellian language, double speak for we're making this shit up
Vault7 UMBRAGE is all I have to say on this matter.
