Alex gave a presentation for the German Oracle User Group last November and the notes are currently on his site in German. The paper is called "Presentation DOAG 2004" and the slides are currently as I said in German. Alex sent me an English version and said he would put the English version on his site in a day or so.
Also Alex will be adding a new paper about SQL Injection in Oracle Forms very soon - watch this page on his site. I will also let you know here when it is out.
I have not had a chance to read the English version of Alex's presentation slides in English as I have had a large deluge of spam emails sent my way over the last 4 or 5 days. A problem of my email address being available on the net and in many newsgroup postings I guess. This has caused me to change the way emails are delivered to my desktop and I have not yet fathomed how to read attachments that the virus / firewall and email client have deemed dangerous to open in the new client software..:-) Otherwise I could comment further on Alex's presentation.
