More than a mid-90s tale, this presentation is a real-life adventure of a sysadmin who is passionate about rock ‘n roll and “all of the dial-up hacker things”. Shuffling through his professional daily activities he became highly involved with remote data communications. And we are not talking (yet) about Trumpet Winsock, m41nb0ard is a SysOp (wow!) of a private BBS and an avid user of other public systems. At a certain day a few users of some of these systems pissed him off, and the uncontrollable motivation of trolling drove him to his first (and possibly only) reverse engineering project. During this presentation he is going to walk you through not only the motivation, but the basic (trust me, for today’s technology very basic) RE techniques utilized to develop a tool to ultimately troll those other users and the possible exploitation of a widely used bulletin board system application. At the end of the day, if you know what PCBoard, Telemate and config.sys are, at least you will feel nostalgic of hearing and seeing application names you thought you would never be seeing at hacker cons in this day and age.
