RedFox (formerly SlySoft) is a software development company based in Belize. The company is most prominently known for its software AnyDVD, which can be used to bypass copy protection measures on optical media, including DVD and Blu-ray Disc media, as well as CloneCD, which is used to back up the contents of optical discs.

The company formerly operated as the St. John's, Antigua and Barbuda-based SlySoft. At some point in February 2016, SlySoft shut down, with its home page replaced by a message citing "recent regulatory requirements".[1] On or around February 16, 2016, AACS LA had requested that the Office of the United States Trade Representative place Antigua and Barbuda on its Priority Watch List of countries that fail to prevent intellectual property violations, with specific reference to SlySoft.[2] However, the company's online forum remained online, and had replaced the brand SlySoft with "RedFox". SlySoft developers also revealed that none of the company's staff were actually based in Antigua, that the company was not involved in legal settlements from AACS LA, and that key staff members still had access to SlySoft's technical infrastructure—including build systems and licensing servers—feasibly allowing development of AnyDVD to continue.[3]

On 2 March 2016, SlySoft reformed as RedFox, under a top-level domain based in Belize, and released a new version of AnyDVD.[4]


  • AnyDVD to remove/disable DRM restrictions and user prohibited operations on DVD films, and to fix structure protections and mastering errors
  • AnyDVD HD - to remove DRM, lock-outs, and UOPs on DVD films and additionally High Definition media, specifically Blu-ray Disc and HD DVD
  • CloneCD - to copy optical discs in raw format
  • CloneDVD mobile - to convert DVD files to mobile video players like the iPod or the PlayStation Portable[5]
  • Game Jackal - to create CD profiles so a disc isn't required when starting the game
  • Game Jackal Enterprise - extended version of Game Jackal with additional features such as automatic distribution of game profiles to client machines[6]

Some products are now supported by Elaborate Bytes such as Clone DVD and Virtual CloneDrive.

AACS and BD+[edit]

SlySoft was the first to offer AACS circumvention that worked for any disc available; previous programs only cracked "compatible" discs using a database of known keys.

On 8 November 2007, SlySoft claimed to have completely cracked BD+. However, this turned out to be incorrect, as subsequent versions of BD+ security code have caused SlySoft to re-design its software. On 3 March 2008, SlySoft updated AnyDVD HD allowing the full decryption of BD+,[7] allowing for not only the viewing of the film itself but also playing and copying disks with third-party software. A third iteration of BD+ was released in November 2008, and was announced to be cracked by SlySoft with the release of AnyDVD HD on 29 December 2008.[8] A fourth version of BD+ security code was discovered with the movie Australia on 17 February 2009, thwarting the effectiveness of SlySoft's software.[9][10]

However, on 19 March 2009, SlySoft updated AnyDVD HD to version which allowed the decryption of the new version of BD+ used by Australia.[11]


On 1 December 2008 SlySoft announced it would for the first time begin charging its customers for updates to its software.[12]

In November 2010, SlySoft initially announced the discontinuation of the lifetime licensing option beginning January 2011. An e-mail[13] announcing the change ahead of time was sent to all registered customers allowing everyone the chance to purchase the lifetime option "while it is still possible;" and the notice was posted to their official forums. In January 2011, all announcements regarding the change were deleted without comment and a new structured licensing plan was put into place; including the lifetime licensing option at the highest priced tier. SlySoft was able to balance the internal cost matter and the licensing strategy in such a way as to allow continuation of the "lifetime" license option. The 'update service' will only allow updates with a valid license and users are warned if they attempt to install an update beyond the license expiry date. If the user cancels the update the current paid-up license will continue to work. If the user continues then a "renewal" is required.

Following the collapse of Slysoft, holders of a SlySoft AnyDVD/AnyDVD HD Lifetime License are required to purchase a new license for use with the RedFox software beginning with Version Version will be able to use the prior license interminably, however it will not have access to updates for the latest decryption of copy-protection.[14]
