Brute force attack was successful Saturday, 13-Feb-99 22:26:29
I don't know if this is defeating the purpose of this project. Since I believe in going at things head first. I went ahead and did a brute force attack on the project file. I used AZPR ( Advanced Zip Recovery ) to Brute Force the zipfile.exe Since "EB" already gave us the password ( Thank God! ) I was able to tweak the program to save some time. Heres the results of a brute force attack For a 10 digit password consisting of probabilities of a-z , A-Z ,0-9 and extend ascii no blank spaces . Possible amount of passwords was around : 59,873,693,923,837,894,660 My computer found the correct password after trying 35,760,000,421,306,086,400 passwords. Since I did tweak the program. I saved a incredible amount of time. But If I had to do this in the wild. Trying all printable characters. It would have taken about 1 1/2 to 2 weeks to crack it with a k6/2 266. This project has really made me appreciate cryptography alot more. ;) Dr. Zen Dr. Zen |
