Merry Christmas or whatever applies or not to your particular case, and much more important, Happy New Year! The world is messed up and it will probably get worse in 2012. Cheer up and be positive! Let me write some quick notes about some stuff: Take a look at Snare’s presentation about OS X Rootkits! Available at Papers section or here. Check out the fantastic Hopper disassembler and decompiler here or at the Mac App Store....
Let me start this with some sort of disclaimer. I do not support/condone stealing credit card information, logins, and other personal information. Disclosing security issues is always a double edge sword and a tricky problem with some politics in the mix. This problem was reported almost 3 months ago to Apple. It’s still not fixed after, at least, two iTunes releases. I perfectly understand the business side of fixing bugs and how business most of the times must come first (I have experience in critical environments where these type of problems can cost a lot of money and bad publicity)....

This is a simple plugin to display Mach-O headers inside IDA, something I miss from time to time. It was a good excuse to mess a little with IDA SDK. It’s not quite what I had initially in mind but it does the job. I was thinking about something more sophisticated such as allow to display only the segment you wanted and so on. Now I am not sure if it’s worth the effort....
This is just a simple post about using Xcode to create IDA C/C++ plugins. Nothing fancy here. For great references about IDA SDK plugin writing check out The IDA Pro Book by Chris Eagle and binarypool.com tutorial. Xcode 3.2.6 is the reference version used. The resulting project loads and compiles without any issues into Xcode 4. Why not doing this in 4? Human brain is misterious (3.x still loads by default on my system)....
