Tools

• Search text in ActionScript source or text tags (can use regular expression)
  • Option to load previous search results
• Search by all P-code files (AS1/2 only)
• Go to Document class (AS3)
• Proxy
  • Configure your browser to use our proxy
  • Proxy sniffs http communication and searches for SWF files
  • Found SWF files can be edited in place and then served via proxy again
• Search memory
  • Search SWFs in other processes memory
• Deobfuscation
  • AS3 P-code deobfuscation (Few technics to remove dead code inserted by obfuscators)
  • Globally rename identifier
  • Rename invalid identifiers (Obfuscators often use wrong characters in identifiers)
  • Rename colliding identifiers (Obfuscators use same names for methods, only with different namespace)
• Time line view
  • Display timeline of objects placed in the frames. See object location in the preview window.

Settings

• Automatic deobfuscation
  • Application can automatically remove dead code and other obfuscated code. This is off by default as it can break decompilation of regular files.
• Simplify Expressions
  • Complex (often obfuscated) expressions are simplified to (usually)one value to make code more clear
• Parallel SpeedUp
  • Application can use parallel approach (threads) for reading SWF/decompilation to be faster
• Disable decompilation
  • AS decompilation can be disabled so only P-code is visible. This can be used if decompilation takes much time for example.
• Add FFDec to SWF files context menu
  • On windows platform, this can add "Open with FFDec" right click context menu to windows explorer
• Highlight document class on startup
  • FFDec can jump directly to AS3 document class after SWF opening
• Auto rename identifiers
  • On SWF opening, automatically execute "rename invalid identifiers" operation
• Open loaded SWFs while playing
  • If you run SWF with Run command in the menu or display in FlashPlayer in the FFDec, all SWFs which are loaded inside ActionScript while run will be then opened in FFDec. This applies to encrypted SWFs loaded from DefineBinaryData tags too. Useful for any kind of AS3 loader.
• Change language
• Advanced configuration for experts

Tag list view

• Special mode where you see exactly how tags are ordered in the SWF file
• You can easily switch between this mode and Resources (folders) view

• Removing tags or other items
• Move tag to specified position with select position dialog
• Move or copy tag to another SWF
• Cloning tags and frames
