View Full Version : Interesting type of serial protection

January 2nd, 2007, 18:27
Ran across this on new years day, registration box contains 3 fields, serial no., name, E-mail, only the serial number box is active the other 2 say "optional", OK, lets fish this sucker, should be easy enough, even says "25 characters", so I set a BP on a logical API, GetWindowTextA or such, BINGO! it spits out a string in short order, with very little fishing involved, but it's a 36 character string. OK so I try different combinations, first 25, last 25, etc but the Enter button stays grayed out - then I notice it now says "required" on the name field and E-mail field. - Name fishing??? and how would you recognize what the name would be??

First time I've ever seen this one, probably any 25 character combination of the 36 characters is a valid serial but for what name?
