Just read about a very novel use of cloud based services. Its Cloud based WPA key cracking service!
Wait a second; did I just mention a wireless key cracking service based on cloud? OMG, that could be devastating for millions of wireless network operating "securely" over WPA shared key. What would happen to them? Aren't we having fair share of attacks on wireless networks already?
Well, friends! This is just one application of much-hyped cloud based infrastructure. It provides you enough processing power at relatively low cost (this is important!), that makes it affordable for this kind of use.
So if this is dangerous, then why are people developing it? I would say this is just one side of the coin. The other (& promising) side is, this low cost key cracking service is to be used for security penetration testing of wireless network. Also, this is a paid service which requires user to make a payment via amazon (which, I believe, is traceable in case of malicious use of the service).
In this note, I just wanted to bring in notice, a different, off-the-track use of cloud services. If this gets you interested, then you can read the full story here.
Do let me know what do you think on this?
