1 Software and CD Protection V2 New, Better, Cracked in nearly the same way as before By: Chris Long

2 This presentation is to be used for educational use only!

3 Why?  To prevent copying of copyrighted software  To ensure integrity of the copyrighted software  Money! These are businesses and they exist on account of money.

4 3 General Schemes  Encryption – talked about in previous lectures  Dongles – separate hardware needed to be plugged in to allow the software to work  CD/diskette protection – tries to prevent the copying of the files needed for the use of the program

5 Dongles The Good – One of the best ways of protecting software. Very hard to crack it needs time and expensive equipment The Good – One of the best ways of protecting software. Very hard to crack it needs time and expensive equipment  The Bad – Expensive to manufacture,about $20 for replacement a dongle, can interfere with the parallel or serial port there attached to

6 Dongles  Two variants  Envelope – Tries to create a defensive shell by means of not decrypting the exe unless the dongle is present and working properly  Function – The dongle is used as a needed function in the program

7 CD Protection The Good – Cheep they add little if any extra manufacturing costs, they discourage the “average user” from copying CDs The Good – Cheep they add little if any extra manufacturing costs, they discourage the “average user” from copying CDs  The Bad – can cause some CD readers to fail or significantly slow down, many can be gotten around using a good CD-R/W drive, the ways around the commercial CD protection are easly findable on the internet

8 Other “CD Protections”  CD Checking – the program accesses the CD for data or just to see if it is there and if it is not stops normal execution  Dummy Files – files that in the file table point to the data of various other files to make it look like the CD is holding more than it actually is  Illegal table of contents – TOC that does not strictly comply with ISO standers, usually two data tracks

9 More other “CD Protections”  Oversize – CDs that are over 660 Mb in size can not be copied onto 74 min CDs with most CD- R/W (not used since the introduction of 80 min CDs)  Physical Errors – the CD is physically damaged usually can not copy, if you still can it copy takes about 1 to 8 hours
