    Curiously vague piece about a guy who does pen testing on mainframes, yet doesn’t seem to know much except self promotion.

    Combine this with a false sense of security. Do you read about mainframe hacks? No. Why?Because of what I said above, juicier targets that are approachable by more people.

    There have been mainframe hacks, IBM goes to great lengths to cover them up. One of the most prominent in recent years was the Nordea Bank hack by Pirate Bay cofounder Gottfrid Svartholm Warg. Allegedly he used the open source Hercules mainframe emulator and bootleg copy of zos to research the system.

      Curiously vague piece about a guy who does pen testing on mainframes, yet doesn’t seem to know much except self promotion.

      He has a decent site that helped me learn a fair bit about z/OS when I was working with it. No argument on the self-promotion bit, although I always thought of him as chipper and not arrogant.

    2. 3

      Overlooked by everyone except Hollywood, maybe. ;)

      Joking aside, IBM’s Redbooks are best source of information on much of what they make. The mainframe guides have plenty of detail for people wanting to learn about them or potential ways to break them:
