Memory resident backdoors in Oracle
David has made a post on his blog about his talk titled "Memory-resident backdoors in Oracle / Deepsec conference", whilst there is not much detail in the actual post (we need to wait for the slides) its quite an interesting idea that i have mentioned a few times in the past. Modifying data in memory is a a good idea to avoid detection but there are still issues around the actual deployment of the backdoor in terms of a completely hidden backdoor / rootkit.
I have also added David's blog feed to my Oracle Blogs Aggregator so its now possible to pick up his posts there as well.
