"hiya" is a form of greeting , mostly used by the British peasants , not trying to offend anyone , just my personal observation . I've never seen any British person with a good education who uses it . It's a telemetry function , usually at it's first launch , hence the name : hiya.browser.360.cn
Of course , again and again , I'm seeing that super duper russian hackers left the telemetry untouched.
The question is why , deliberately or just due to their incompetence ?
Host Name: puv.tt.browser.360.cn is a well known server that needs to be blocked , also.
Again, I warn everyone , do not use chino-russian "things" .
