Hi, it's often difficult to find old versions of vulnerable softwaresit's usefull to have these old versions to test an exploit, study a vulnerability or doing a patch analysis... it's also usefull to test a fuzzer, a scanner... for a course or a challenge...
so i think about to build a little reposiroty with old versions of little softwares (free or trial)
if interested or could help, please visit this page: https://www.securinfos.info/old_softwares_vulnerable.php Cheers /JA
