How did someone download pornography worth 1,500 rubles through my grandmother's modem?

Question

Computer networks

Grandma has a modem from a megaphone. I paid 300 rubles per month. The last time I received a receipt for 1500 rubles. A request to extract traffic returned a bunch of adult sites and movie downloads. What could happen? (the option that the grandfather is naughty at night is not considered)

Answer 1

The amigo browser and similar malware could. Botnet for cheating views.
