What do you think is the most dangerous stuff on the internet?
I think it is "Remote Access Trojan (RAT)"

1) Hackers uploaded the RAT exe file to a exploit server.
2) Visitors visit the server/hackers send the affected website link to the particular victims.
3) The malicious code is written in js file and the js file will automatically downloaded to visitor's PC
    (C:\users\pcname\AppData\Local\Temp)
4) The js file automatic install the RAT Program?
5) The RAT program will auto send the victim's IP address and username/password to the hackers each time the visitors online?
