8E36 Seconds and Microsoft Products even Vista RRS feed

  • Question


    Hi friends,

    I would like to share a simple method to break the Microsoft products just created on simple facts and figures, Windows Vista key, as well as near all Microsoft's product keys, is build according following pattern: xxxxx-xxxxx-xxxxx-xxxxx-xxxxx.

    Now we have deal with 25 alphanumeric characters. In English alphabet there is 26 case-insensitive characters and 10 numbers, so we have a deal with 3625 combinations, which about equals to 8 with 38 zeros. So, let's take really quick computer and do bruteforce over UI thread of Windows. In this case we can work with 10ms delay, so we can check 100 combinations a second. Now, in worse case, we'll find a key within 8E36 seconds.

    Here is simple calculation:-

    36^25 combinations = 8E38 combinations

    Time taken @ 100 combinations per second = 8E38/100 = 8E36 seconds.

    8E36 seconds = 2.2E35 hours

    So we can break Microsoft any product even Windows Vista within 2.2E35 Hours or 8E36 Seconds


    But it is pretty long… So till date Microsoft need not to worry but in near future like couple of years they need to worry about it.

    BUT there are some rules, we can minimize the number of possibilities to about 8E15 Seconds and also with the help of some hardcore computers.

    I will not explain how u can break it in 8E15 seconds becoz I am with Genuine Microsoft Products and would suggest you to use their genuine products.

  • I posted this just to attract Microsoft regarding there security and to improve it by themselves and also hope the above method will not help a lot to hackers but shows the security concept.
