Um protótipo que demonstra já o potencial da IA no cibercrime!

@elonmusk This is as crazy as you are being

[Nuno Duarte Mendes @_Nuno_Mendes_]

@elonmusk You can't buy education, otherwise you'd probably be the most polite guy in the world. Money can buy ego-centrism and arrogance so you bought the whole world stock together with Donald Trump.
Anyway, partially thanks to you and Trump administration, Europe is waking up

#ESETresearch discovered a signed, vulnerable, ad-injecting driver from a mysterious Chinese company. This threat, which we dubbed HotPage, comes self-contained in an executable that installs its main driver and injects libraries into Chromium-based browsers. 1/7
