PD War Collection Program 2 By Hal Of Pheonix Modified by: Dark Angel of PHALCON/SKISM FindAV version 1.5 Released 27 Jul 92 By Dark Angel of PHALCON/SKISM In the beginning, there was MakeAV and all its counterparts. These programs used a brute-force approach to find PKZIP serial numbers. They ran PUTAV, PKZIP, and PKUNZIP repeatedly until a legitimate serial number was found. Although they worked, these programs required hours, often days of running, as well as much wear and tear on the hard drive head. Then FindAV was released by HAL of PHOENIX. FindAV was many, many times faster than MakeAV. Instead of running the PKWare files over and over again, FindAV used an algorithmic approach similar to the one used by PKWare when calculating serial numbers for registered clients. It was a marvelous program, but it, too, had its limitations. The continual display of numbers was aesthetically pleasing, but it took much valuable processor time, slowing down the search for the holy serial number. E-FindAV was released, once again speeding the search time by a large factor. E-FindAV monitored the running of FindAV, turning off the display until the serial number was found. This was a tremendous improvement. However, the user had to sit through a tedious, lengthy, entirely unecessary introduction screen before E-FindAV would execute FindAV. This was unacceptable. Additionally, E-FindAV failed to fix some fundamental problems with FindAV. For one, FindAV stopped after finding the first serial number. While this is fine for most people, it is not desirable when finding existing serial number/validation string combinations. Second, FindAV had a few bugs. The first bug occured only in 386 mode. FindAV would "miss" some legitimate serial numbers which it would catch in 8086 mode. This was, once again, undesirable when looking for existing serial number/validation string combinations. FindAV would also run into an infinite loop in certain instances in 8086 mode. This, too, was unacceptable. Third, FindAV would not log the serial numbers found in a file. Thus, the user had to manually copy the number onto a sheet of paper and transfer it to a file for later reference. Fourth, FindAV would not let the user start searching for a serial number from any number except 1000. If the user wished to find starting from, say, 2 billion, he or she would be forced to create a MAKEAV.DAT file and hex-edit the appropriate values. Last, both FindAV and E-FindAV used rudimentary disassembly-proof code which precluded users from adding features to the program. FindAV version 1.5 fixes these problems. It is essentially the same program as the originally released version by HAL of PHOENIX, but with all the fixes and enhancements mentioned above. Command line options: /B - begin at number You can now start the search from any number, be it 0, 4,294,967,295 or anything in between. This serves several purposes. Should the data file be corrupted, it is not necessary to hexedit the data file to restart from the last position. This option also facilitates the coordinated running of FindAV on multiple machines. In this manner, each machine can start the search at a different point. The value following the /B overrides the value in the FindAV.DAT data file. Syntax: FindAV /B ### Example: FindAV /B 478293 /S - supress output Searches may be expedited somewhat with this supress output option. This eliminates the unecessary on-screen reporting of a sucessful finding. Logging via the AVS.DAT file is preserved. The 'D'isplay command continues to function under this mode. Syntax: FindAV /S Valid keystrokes in FindAV: ESC - Terminate calculation Pressing the ESC key causes FindAV to terminate after saving the status of the run in FindAV.DAT. 'D' - Display Pressing the 'D' key causes FindAV to display the current search number on the screen. This function was originally part of the main loop. However, it consumed countless clock cycles, so it was eliminated to save precious time. Files created by FindAV 1.5: AVS.DAT - log file The AVS.DAT file is created by FindAV. FindAV uses this file to record all sucessful serial number finds. It consists of the company name followed by multiple lines of serial numbers. If FindAV detects the file in the directory, it will append serial numbers to the end. FINDAV.DAT - save file The FindAV.DAT file is created by FindAV when the user terminates calculation. It contains the company name as well as the current search number. It is useful when the user does not wish to search an entire range in one running. FindAV will automatically resume operation if it detects FindAV in the current directory. FindAV 1.5 has data file compatability with version 1.0.
