Google in its current quarter list has ranked this Raipurian on the 11th spot in world.Sahu has been rewarded by some of these websites, which have paid him sums of $100 to $20000.Advising caution to internet users, Sahu said, "There are websites which are highly vulnerable and can easily be hacked. I informed them about the loopholes in their security systems. After they verified my claims, they included me in the list."Monendra, who is currently involved in network research also imparts training to the state police personnel on handling cybercrimes. "I have been training state police for the last two years. Their cybercell is not up to the mark and needs upgradation, as cyber crimes have increased'', he added.On privacy measures that are recommended by various websites, Monendra said, "Indian websites are highly vulnerable. In fact, big names like Gmail and Facebook are also witnessing frequent security breaches.""It's important to create awareness among people for security of their Gmail IDs, Facebook passwords, etc. Hacking is now a big business and with an increase in the number of cybercrimes and cyberwars, one should take serious note of the security tips advised by websites. Try shopping only from trusted web portals," said the hall of fame member."Online banking is a big threat, as it makes things easier for hackers. Algorithm science makes it easy for them to trace your ATM card number or password. During online transactions, one is often asked to provide credit card details, which can be traced by a hacker. I would suggest internet users, to lessen their number of logins to avoid such misuse", he added.On vulnerability of wireless networks like wi-fi, Sahu said, "Wi-fi networks available for public use in places such as colleges, offices etc are more vulnerable."White Hat: Hacks website and tells the owner, works judiciously.Black Hat: hacks website for his personal benefit.Grey Hat: Intentions aren't clear.
