Software cracking (known as "breaking" mostly in the 1980s[1]) is the modification of software to remove or disable features which are considered undesirable by the person cracking the software (software cracker), especially copy protection features (including protection against the manipulation of software, serial number, hardware key, date checks and disc check) or software annoyances like nag screens and adware.
A crack refers to the means of achieving, for example a stolen serial number or a tool that performs that act of cracking.[2] Some of these tools are called keygen, patch, loader, or no-disc crack. A keygen is a handmade product serial number generator that often offers the ability to generate working serial numbers in your own name. A patch is a small computer program that modifies the machine code of another program. This has the advantage for a cracker to not include a large executable in a release when only a few bytes are changed.[3] A loader modifies the startup flow of a program and does not remove the protection but circumvents it.[4][5] A well-known example of a loader is a trainer used to cheat in games.[6] Fairlight pointed out in one of their .nfo files that these type of cracks are not allowed for warez scene game releases.[7][4][8] A nukewar has shown that the protection may not kick in at any point for it to be a valid crack.[9]

On the Apple II, the operating system directly controls the step motor that moves the floppy drive head, and also directly interprets the raw data, called nibbles, read from each track to identify the data sectors. This allowed complex disk-based software copy protection, by storing data on half tracks (0, 1, 2.5, 3.5, 5, 6...), quarter tracks (0, 1, 2.25, 3.75, 5, 6...), and any combination thereof. In addition, tracks did not need to be perfect rings, but could be sectioned so that sectors could be staggered across overlapping offset tracks, the most extreme version being known as spiral tracking. It was also discovered that many floppy drives did not have a fixed upper limit to head movement, and it was sometimes possible to write an additional 36th track above the normal 35 tracks. The standard Apple II copy programs could not read such protected floppy disks, since the standard DOS assumed that all disks had a uniform 35-track, 13- or 16-sector layout. Special nibble-copy programs such as Locksmith and Copy II Plus could sometimes duplicate these disks by using a reference library of known protection methods; when protected programs were cracked they would be completely stripped of the copy protection system, and transferred onto a standard format disk that any normal Apple II copy program could read.
A specific example of this technique is a crack that removes the expiration period from a time-limited trial of an application. These cracks are usually programs that alter the program executable and sometimes the .dll or .so linked to the application and the process of altering the original binary files is called patching.[10] Similar cracks are available for software that requires a hardware dongle. A company can also break the copy protection of programs that they have legally purchased but that are licensed to particular hardware, so that there is no risk of downtime due to hardware failure (and, of course, no need to restrict oneself to running the software on bought hardware only).
Advanced reverse engineering for protections such as SecuROM, SafeDisc, StarForce, or Denuvo requires a cracker, or many crackers to spend much more time studying the protection, eventually finding every flaw within the protection code, and then coding their own tools to "unwrap" the protection automatically from executable (.EXE) and library (.DLL) files.
But you can play POC classic for one hour without charge and I think it is fair enough tocharge you if you want to play such an old game for more than one hour. Anybody who bought an AMIGAversion send us a note with a proof of purchase or so and I will send the pocsilver free of charge.(that were not many people that bought it in the past - most had a crack), and we also never got license feefrom the distributor at these times.... But the payment for the classic game is also to support us for the new games. Now we have micropayment and I want to use it also for the new games.
There is, however, a significant weakness to this system. Specifically, the response is generated in such a way as to effectively reduce 16-byte hash to three smaller hashes, of length seven, seven, and two, respectively. Thus, a password cracker has to break at most a 7-byte hash. One Windows NT vulnerability test program that I used in the past reported passwords that were "too short," defined as "less than 8 characters." When I asked how the program knew that passwords were too short, the software's salespeople suggested to me that the program broke the passwords to determine their length. This was, in fact, not the case at all; all the software really had to do was to look at the last eight bytes of the Windows NT LanMan hash to see that the password was seven or fewer characters.
The Deep Crack algorithm is actually quite interesting. The general approach that the DES Cracker Project took was not to break the algorithm mathematically but instead to launch a brute-force attack by guessing every possible key. A 56-bit key yields 256, or about 72 quadrillion, possible values. So the DES cracker team looked for any shortcuts they could find! First, they assumed that some recognizable plaintext would appear in the decrypted string even though they didn't have a specific known plaintext block. They then applied all 256 possible key values to the 64-bit block (I don't mean to make this sound simple!). The system checked to see if the decrypted value of the block was "interesting," which they defined as bytes containing one of the alphanumeric characters, space, or some punctuation. Since the likelihood of a single byte being "interesting" is about , then the likelihood of the entire 8-byte stream being "interesting" is about 8, or 1/65536 (16). This dropped the number of possible keys that might yield positive results to about 240, or about a trillion.
As a slight aside, another way that people try to prove that their new crypto scheme is a good one without revealing the mathematics behind it is to provide a public challenge where the author encrypts a message and promises to pay a sum of money to the first person — if any — who cracks the message. Ostensibly, if the message is not decoded, then the algorithm must be unbreakable. As an example, back in 2011, a $10,000 challenge page for a new crypto scheme called DioCipher was posted and scheduled to expire on 1 January 2013 — which it did. That was the last that I heard of DioCipher. I leave it to the reader to consider the validity and usefulness of the public challenge process.
WPA/WPA2 cracking technique: Our devices have wireless passwords stored so that we do not enter the password on the same device again and again. The attackers take advantage of this by forcefully de-authenticating all the devices on the network. The devices will try to auto-connect to the access point by completing the 4-way handshake. This handshake is recorded and has the hashed password. The hashed password can be brute-forced by using a rainbow table.
Wireless hacking tools are the software programs specifically designed to hack wireless networks by either leveraging dictionary attacks for cracking WEP/WPA protected wireless networks or exploiting susceptibilities in wifi systems.
WepAttack can be used to crack 802.11 WEP Keys using a dictionary-based approach. The tool can capture the network dump file received from pcap or libpcap etc. The tool is open source and supports the Linux platform. One thing to be noted here is that the attack is active and not passive in nature. The tool will just test the dictionary words to get the working key. The key requirement for this is a working LAN card.
Fern WiFi Cracker is a python based tool that can be used for WEP/WPA/WPA2 cracking, session hijacking, ARP request replays, and performing brute force attacks. It is able to save the key in the database on a successful attack. It supports an automatic access point attacking feature and has an internal MITM engine as well. This too is also pre-bundled in kali.
KisMac is a wireless network discovery hacking tool specifically for Mac OS X. This classic 802.11 WEP/WPA cracking tool is not for beginners, rather, quite popular among advanced professionals. It tries to crack WEP and WPA keys by scanning for networks passively on supported WiFi cards by any flaw or leveraging any flaw or using brute force. 2ff7e9595c
