  • Recovery: UPX Version 1.2.5

    Good Afternoon, I am looking for version 1.2.5 of UPX. We seem to have lost our version of UPX in the last upgrade. I realize the requested version was released in 2004, but I don't have any other choice. On the website, I see versions dating back to 3.0.0, but I'm kind of in a bind. The company I work for is required to provide maintenance for our products. As such, I am looking for the...

  • Can't read /proc/self/exe

    I need to know the current executable's path. '/proc/self/exe' or '/proc/CURRENTPID/exe' must be read to implement this function for linux box. It works well for program unpacked.But I found that '/proc/self/exe' was broken when an elf executable was packed by upx. Is it possible to patch upx to keep '/proc/self/exe' or just save executable path in some way (such as environment string)?...

  • Comment: UPX doesn't recognize D3X (DJGPP) .EXEs

    It's not alpha-quality, it's just called "alpha" for some odd reason. UPX handles it fine for watcom/le, so it's only the djgpp2/coff part that isn't detecting it. (BTW, it's only a DPMI host there, not an extender.) The original website is down, and it's hard to find other than mirrored on my site, but the main advantage, IMHO, is that it can build with GCC + NASM (no TASM needed). I have no...

  • All UPX compressed EXEs Quarentined by Norton AV 2010

    This is NOT a bug in UPX but it will affect many UPX users. Latest Norton AntiVirus release (2010 edition), their "SONAR" subsystem detects all exe files compressed with UPX (tested v303 or v304) as having "suspicious activity" and BY DEFAULT quarantines them (i.e. removes the exe to a quarantine area), but only after 1-2 minutes of total nonresponsiveness before Notron pops up a message box...
