I'm very proud to be hosting these documents on my site, courtesy of the KGL. The essays (hopefully more will be forthcoming in the future) come highly recommended for both aspiring reverse engineers and old hands alike and definitely aren't as 'newbie' as the about summary below might suggest ;-), you are encouraged to read them and work through the concepts discussed slowly, the more time you invest in these documents the more you will gain from them. Follow this page carefully to find your path and learn.


About the KGL

KGL is a small group of (mostly) security-oriented individuals, who seek to expand their knowledge. As a group, they have knowledge in the fields of PLs, RE, networking, OSs, etc. Most members also have an excellent formal education. The essays themselves are written for people who want to master the field of RE. The first essays are targeting the (rather complete) newbies audience, although more advanced topics will be covered as time goes by (and the readers obtain some knowledge).


Contacting the KGL

I think I can safely say that my FAQ regarding e-mails probably applies to KGL, so please read it else you might not get a reply. Once again, do not send requests for cracks / programs etc. (they will be IGNORED I can assure you). However you are encouraged to send e-mails with comments / corrections / requests for topics and suggestions.
