- Before getting into our open discussion..we recommend you listen to the IBM Fight Song. Yeah, srsly!
Security Justice Open Discussion: Hacking the dinosaurs! Breaking AS400, PBX/VM systems and more!
- General IBM hacking tips (If you want to go after mainframes or iSeries/AS400 you will need a TN3270 client)
IBM Redbooks – Required resource when looking at any IBM product - Hacking iSeries/AS400 (Commonly referred to as midrange systems. AS/400 are NOT mainframes!)
Good book on this called “Hacking iSeries” by Shalom Carmel and his whitepapers.
Stankdawgs Hope5 AS/400 Talk – AS/400: Lifting the veil of obscurity.
Be sure to check for default accounts and passwords Commonly have SMTP XPND and VRFY enabled which makes account enumeration easier. Most have a modem attached for remote diagnostics. Sometimes can be insecure. Same thing goes for accessories such as drive arrays. - Hacking Mainframes (often a critical system so tread lightly)
Keep in mind a “Test” mainframe might just be an LPAR (Logical Partition) off the production system. So disruptions to the “test” system could impact production. - General penetration testing tips
Users manually sync passwords – If you get a users password from another system try it on the target system.
Clear text protocols abound. MITM attacks can be your friend. Just don’t take the companies mainframe offline, they probably need that. - PBX/VM
Check for default usernames/passwords on voicemail and phone systems and never under estimate wardialing!
PBX’s often run UNIX-based OS’s
PBX’s tend to be treated as “appliances” which is a fancy way of saying “we’re not going to patch it” - TANDEM Security
- Crusty UNIX
Older AIX versions use crypt() for password hashing, and only support 8 character unsalted passwords. It will let users set longer passwords, it just only uses the first 8 chars!
Telnet, rhosts, rlogin, rsh are all commonplace on older big iron UNIX
Clustered UNIX boxes work by allowing password-less root login between each cluster member. This can happen over SSH, but often happens over telnet, rsh, rlogin, etc. Some vendors even still reccomend this! Own one box, own them all. Even better, spoof one of the hosts (easy for rtools) and you have root. - HVAC Systems
Some connected via modem, others on the network. Default credentials almost guaranteed bacause they are usually set up by non-security aware HVAC mechanics. Newer web based management consoles give you full control of the HVAC system. Use caution when pentesting HVAC systems as messing with these can cause human safety issues!

This fun special edition episode was recorded last year at the Ohio Linux Fest. The reason it took so long to release was mostly because of the “editing challenges” (Froggy likes to hijack our podcasts) and we wanted to release this at the beginning of 2009 to drum up some hype for Notacon 6 which will be held April 16th – 19th, 2009 in Cleveland Ohio.
