All AutoHotkey (AHK) coders read: No more upx packing of compiled ahk utils

<< < (3/8) > >>

mouser:
There is a new poll on the UPX form asking whether people approve of the idea of changing AHK compiler behavior to not use UPX by default.
If you have an opinion on this please vote: http://www.autohotkey.com/forum/viewtopic.php?t=53219

Apathetic_Coding:
This tool written by ladiko over at the AHK forum not only gives you more options when compiling your AHK scripts but also has an option to NOT use UPX.

Oh very nice find.  :up:

I just updated GridMove with a non-compressed executable.
Let's hope it get us less problems!

MilesAhead:
Looks like UPX is a bit smarter about compression of exe/resources than 7-zip. Using the Compile II mentioned with UPX off a trivial AHK script with icon resource compiles to about 486 KB instead of 277 KB.  After compressing both with 7-zip the one with no UPX compresses to a 258 KB download instead of 213 KB. I haven't done any trials with larger apps since I only use AHK for very small scripts.

With the rate these viruses propagate has anyone done any calculations on the possibility of random signature matches?  Or are the permutations so large that it's trivial?  Before Linux had to be able to handle all these Windows file formats, most files didn't even have an extension.  You relied on a program called 'file' iirc that looked at the start of the file and guessed if it was a printer configuration file, a bash script, an executable etc..
I wonder how long it will be until just any random string of bytes at the start of a file matches some virus signature somewhere?
