Recently I saw some old BS about how secure IBM i based systems are and I just have to respond. First of all with all due credit to the OS system developers at IBM, IBM i is by far one of the most secure operating systems there is with minimal exposure to the types of hacking found in the LINUX, UNIX, or Windows world where access is gained by exploiting vulnerabilities in the OS.
Today, the statement that IBM i is completely secure and cannot be hacked is pure unadulterated BS! It can be hacked much easier than most folks could ever imagine. Every since IBM introduced support for pointer manipulation in RPG and other ILE languages, they opened the OS to hackers. It is still very difficult and not worth exploiting.
BUT ... why would a hacker bother with the OS when huge numbers of IBM i based shops leave the front door to their systems wide open over the Internet?
There many exposures ranging from failure to change the password on key system profiles so a hacker can just login as QSECOFR or other powerful profile. A little more difficult but not much is the ability to run SQL INJECTION attacks on thousands of web pages that your developers probably don't even know are exposed.
I recently did a Google search on "IBM i hacked" and got 3.7 million results. The old BS that the IBM i has never been hacked is pure myth. I personally know of several including a major bank, a major automobile manufacturing company, and several retail operations.
If my word isn't good enough them Visit Help Systems web site (they now own PowerTech one of the largest IBM i security companies) and get their
"State of IBM i Security - 2012" and read it for yourself.
The study reveals that:
- 81% of systems unknowingly compromise their library security
- 66% of systems don’t monitor network access to their data
- 74% of systems give users too much power.
In other words most IBM i shops are extremely vulnerable to security penetration, hacking, and loss of confidential customer information. All the time your IT Staff in blissful ignorance will tell you everything is wonderful and your system is hack proof.
They may even quote an incorrect statement that IBM at one time offered a Million Dollar reward for anyone who could hack an iSeries system (it was called iSeries at the time). IBM had to back off in a big way as studies quickly revealed that IBM i can indeed be hacked and even worse, most users, IT managers, and other IBM i practitioners didn't know how to provide basic protection form hackers.
There is no magic in hacking an IBM i system, you just drive through the front gates and take what you want. The door is usually open and there is usually a big welcome mat!
