Undocumented MSVC
Some ongoing research. For obvious reasons I can only share results and tools, but not actual sample data.

Reminder to self: IDA load all sections
Just a reminder to myself. Edit cfg/pe.cfg inside the IDA installation folder to configure the PE loader to load all sections: // Always load all sections of a PE file? // If no, sections like .reloc and .rsrc are skipped … Continue reading
dumbin.exe, editbin.exe, lib.exe …
They’re all just slim wrappers around the actual link.exe, not using a common DLL or so, but actually invoking: dumpbin.exe simply invokes “link /dump” and failing that “link.exe link /dump” editbin.exe simply invokes “link /edit” and failing that “link.exe link … Continue reading
Running IDA 7.x/8.x inside Crossover 21/22
For a few versions I had issues running IDA Pro in Crossover with IDAPython enabled. Prior to the starting issues, everything worked fine, e.g. in the IDA 6.x version range. Please note that the setup of IDA Pro also succeeded … Continue reading

The German federals (BKA = Bundeskriminalamt, roughly the German equivalent to the FBI in the US) are still looking for someone with the qualifications to write what had been dubbed “Bundestrojaner” (literally: federal trojan) in 2008. This means that first … Continue reading

canyoucrackit.co.uk – yes we can ;)
So the British Government Communications Headquarters (GCHQ) wants to recruit smart people. Well, there should be enough around. Although they seem to look for some 1337 h4x0rz, not some serious people from all indicators. The original one (MD5: 1585DFECC90AE7549814DCE52CA4EDDA) filled … Continue reading

Bundestrojaner gefunden?
Heute wurde ich, unabhängig voneinander, von mehreren Leuten auf die Geschichte mit dem angeblichen Fund des Bundestrojaners durch den CCC hingewiesen. Unabhängig davon, ob es sich um das handelt wovon alle Welt ausgeht, machte mich der bei F-Secure gezeigte Bildausschnitt … Continue reading

Eine neue Sau ist im Dorf …
… beziehungsweise wird durch’s Dorf getrieben: Hacker. Böse, fiese Hacker. Auf Begriffe muß man da nicht mehr achten (eigtl. sind Cracker gemeint). Glücklicherweise kommt ja jetzt das Cyber-Abwehrzentrum (was für ein Begriff, gell?) in Bonn. Das schlimme ist nur, daß … Continue reading

“The system cannot execute the specified program.”
There is a pretty interesting article over at winprogger.com about the problems connected with IMAGE_DLLCHARACTERISTICS_FORCE_INTEGRITY (set through /integritycheck ever since VS2005) and ERROR_INVALID_IMAGE_HASH (aka Win32 error code 577). Now, I’ve been fighting with this problem for two full days and … Continue reading

Annoyance in TortoiseCVS fixed
Quite a while ago I reported a bug in TortoiseCVS 1.10.x (the Unicode versions) which more or less affects everyone that is using an alternative file manager. I for one use SpeedCommander and can highly recommend it, although for non-German … Continue reading

Yippie! IDA 5.4 Pro released …
My personal highlight is still the Bochs debugger, but I am sure I’ll take the chance and also look into the newly acquired kernel debugging features. Check out the highlights over here. // Oliver
