Software Cracks

Software cracking is reverse software engineering. It is the modification of software to remove protection methods. The distribution and use of the copies is illegal in almost every developed country. There have been many lawsuits over the software, but mostly to do with the distribution of the duplicated product rather than the process of defeating the protection, due to the difficulty of proving guilt.

The most common software crack is the modification of an application’s binary to cause or prevent a specific key branch in the program’s execution. This is accomplished by reverse engineering the compiled program code using a debugger until the software cracker reaches the subroutine that contains the primary method of protecting the software.

The binary is then modified using the debugger or a hex editor in a manner that replaces a prior branching opcode so the key branch will either always execute a specific subroutine or skip over it. Almost all common software cracks are a variation of this type.

Proprietary software developers are constantly developing techniques such as code obfuscation, encryption, and self-modifying code to make this modification increasingly difficult. In the United States, the passing of the Digital Millennium Copyright Act (DMCA) legislation made cracking of software illegal, as well as the distribution of information which enables the practise.

However, the law has hardly been tested in the U.S. judiciary in cases of reverse engineering for personal use only. The European Union passed the European Union Copyright Directive in May 2001, making software copyright infringement illegal in member states once national legislation has been enacted pursuant to the directive.

The first software copy protection was on early Apple II, Atari 800 and Commodore 64 software. Game publishers, in particular, carried on an arms race with crackers. Publishers have resorted to increasingly complex counter measures to try to stop unauthorized copying of their software.

One of the primary routes to hacking the early copy protections was to run a program that simulates the normal CPU operation. The CPU simulator provides a number of extra features to the hacker, such as the ability to single-step through each processor instruction and to examine the CPU registers and modified memory spaces as the simulation runs.

The Apple II provided a built-in opcode disassembler, allowing raw memory to be decoded into CPU opcodes, and this would be utilized to examine what the copy-protection was about to do next. Generally there was little to no defense available to the copy protection system, since all its secrets are made visible through the simulation.

    Steelers had a record of 4-5 in 2016 and managed to go 11-5 and make the AFC championship game. 1-2-1 doesn't scare me.

    Prime is delusional, the Steelers are toast no matter how much better they get. They are just to far in the hole and Prime is living in the past. Baltimore or Cincinnati will win the division and probably both make the playoffs regardless of who wins it. That leaves the Steelers outside looking in as their division leaves them in the dust, they might even finish last in the north.

    Keep sleeping on Baltimore. Cinci caught them sleeping but best believe they gonna lock them in and throw away the key at the bank in the rematch… Hard to beat a team putting up 32 a game and giving up 14….. Disrespect Flacco all you want he ainโ€™t no fluke this year and that Defence is SPECIAL.

  • Raphael VanBlaricom October 3, 2018 at 9:15 pm

    Question for the panel. Le'Veon Bell is not going to show up until week ten. Does he needs to actually play or just show up? Can his back or leg suddenly start to hurt and still get credit for the season?

  • Rami Herzellah October 3, 2018 at 9:15 pm

    These three need their own show!

  • Roberturt October 3, 2018 at 9:15 pm

    Preshow conversation: "Ok so we're gonna talk about the steelers. You're going to say the steelers will turn this around, you're going to say the ravens are better, and you're going to pretend the bengals are actually going to go to the playoffs, but no one picks the browns, even though they have the same record as the steelers. Ok? lets go out there"

  • D Gly October 3, 2018 at 9:15 pm

  • Chris Warren October 3, 2018 at 9:15 pm

    Matter of fact, the fact that its going bye a down to the wire dogfight for afc north teams makes me feel like everything is normal. The comfort that comes from familiarity. Makes me feel warm and fuzzy inside. Ahh the good ole days. Fighting for every inch so that just maybe, just maybe you might get into the playoffs. Good! Thats what im talking about.

  • Chris Warren October 3, 2018 at 9:15 pm

    Trying to determine what teams are in what teams are out. You cant play that game with the steelers. The only thing that counts the steelers out is statistic impossibilities. Meaning, there is not enough games left for them to get in. That is the only time you can ever argue that steelers are out. If you want to argue steelers are in vs possible. You can argue that all day. But noone, counts the steelers OUT. Only thier record and games left to play. That being said. I dont view steelers as being in. I view them as possible.

  • Adrian Cooke October 3, 2018 at 9:15 pm

    Stop talking about my STEELERS ๐Ÿ˜ ๐Ÿ˜ญ๐Ÿค•๐Ÿค’

  • William Powell October 3, 2018 at 9:15 pm

    They just don't want give the Ravens credit, Baltimore is just a good team, The Ravens is the team they should be decussing instead of Steelers.

  • Brian October 3, 2018 at 9:15 pm

    Why do you always have to have a bra doing these shows? These are these are professional football players talking to a bro who has no clue to What It's Like on the field.

  • andri marpaung October 3, 2018 at 9:15 pm

    They should do this more often, seeing Prime and Shannon arguing while Ladainian stuck awkwardly in the middle is gold,…

  • Noah Winfield October 3, 2018 at 9:15 pm

    Bengals winning the north ya dig

  • No Name October 3, 2018 at 9:15 pm

    they're still dealing with the loss of ryan shazier, im not sure why nobody talks about this…. and there definitely was no player in the draft to replace shazier

  • TigersTeeth October 3, 2018 at 9:15 pm

    If the Steelers continue to play like they have been playing this season, they will not advance to the playoffs. No defensive stars, Ben is declining, you let Leveon walk, whatโ€™s next? Antonio breaks his leg?

  • Sir Jr October 3, 2018 at 9:15 pm

    The one thing that comes constant is a bill

  • port folio October 3, 2018 at 9:15 pm

    Last year, La'Veon Bell was carrying Big Ben's overrated fat ass with the help of the deadliest receiving core in the league led by AB and supported by Smith-Shuster and Bryant. Now Ben is playing without Bell and without Bryant and his true value is showing.
