sorry @steemcleaners,My intention was not to do any kind of plagiarism.As I have learned ethical hacking from the internet and by reading books.I am using the software of spytech and Refog but I forget to give source link of software.I am trying to explain ethical hacking in my own words and experience but sometimes I have to take help from internet for explaining It.From next time I will follow the rules.Please give me one more chance.I hope you will help me.thank you.
