Skype 5-way Calling Limit Cracked

Posted by ryuzaki0 on from the well-isn't-that-unsurprising dept.

BobPaul writes "It turns out when Skype limited 10 way calling to Intel Processors only it really was arbitrary! Maxxus has a patched version of Skype that allows 10-way calling regardless of the processor installed. There's also info about the patch: "The patch is the result of two phases: code analysis and design of the patch. The code analysis, or reverse engineering, reveals the relevant code block, which overrides Skype's limitation for Intel's dual-core CPUs. The patch design isolates the minimal set of instructions that need to be modified to cancel this limitation." Windows only so far."

  1. I don't know that this is such a big deal... by Kaldaien · · Score: 0, Flamebait

    Any idiot with a disassembler can locate a CPUID instruction with minimal effort... I have written many NOCD patches myself in the past and it often takes 30 minutes to an hour to find the conditional jump(s) that branch the execution when a CD is not present. Unless Skype checks the checksum of the binary, this is hardly news worthy.

    Look, that's the definition of the word, jackass. Just because you don't like it, don't point it at me. Go look it up in the fucking dictionary before you start raving at others because you're pissed off. Just because we use bribe as a way of saying "gaining influence" in nefarious context doesn't mean that's the only way it can be used.
