Welcome back to our next SiegeCast!

On October 13th at 3pm EDT we will be presenting “BUFFER OVERFLOW 101”

There are lots of us who want to know more but are either overwhelmed by the idea that buffer overflows are beyond their capabilities or just don’t know where to get started. This is a 101-level talk; Mike Saunders will talk about how a buffer overflow works, how to fuzz an app to identify an overflow opportunity, and how to create a simple overflow that will result in a compromise of a target system. At the end, you will have the information and resources to help you write your first overflow!

We encourage you to sign up for this webcast, as well as become part of the Red Siege community discord –

Tim Medin and Corey Overstreet will be in the discord as well answering any questions along side the discussion.

There, we will be taking our questions and interacting with the community, as well as posting links the coincide with the conversation.

We look forward to seeing you!
