Comment on Opening *.txt file is dangerous on Windowsparent

Comments

A bit of digging around suggests it's a DLL preloading attack which somehow convinces the target apps to load the local directory instance of the dll, rather than the system version.

http://www.crn.com/news/security/226900204/microsoft-warns-u...

has a bit of detail, but not specifically about this attack.

I guess it's conceptually similar to doing something like

    export PATH=.:$PATH; cat foo.txt 
where 'cat' is an executable file in the current dir.

The actual linux equivalent would probably involve $LD_LIBRARY_PATH ($DYLD_LIBRARY_PATH on OSX, not sure about other unices).
