Replacing strings inside SWF [closed]

Answer 1

If the files are using actionscript 2 maybe you can disassemble and reassemble using http://flasm.sourceforge.net/ (And of course: modify the strings before reassembling). For as3 adobe provides a decompiler that might be usable to achieve the same, but I don't think your flash will be as3 if you've inherited it.

Answer 2

How about this one? http://code.google.com/p/swfreplacer/wiki/Intro

Answer 3

You can use Apparat for this kind of task. It allows you to alter ActionScript 3 bytecode in SWF and SWC files.

I would prefer the Scala source branch for your task. Basically the code would look like this:

val swf = Swf from "in.swf"
for(tag <- swf.tags) {
  (Abc fromTag tag) match {
    case Some(abc) => {
      val strings = abc.cpool.strings
      for(i <- 1 until strings.length) {
        if(strings(i) == 'search) {
          strings(i) = 'replacement
        }
      }
      abc write tag
    }
    case None =>
}
swf write "out.swf"

Answer 4

You could try Swiffotron which includes the ability to replace text both on the stage and in actionscript.

Here is a unit test input file from the project which shows how it could be done:

Answer 5

You could try Burak's URL Action Editor -- it says URL, but I'm pretty sure it lets you edit any text in a SWF. I haven't used it, but I have used his ActionScript Viewer, which works wonderfully.

Answer 6

Apparat ended up working great for this (I have some legacy files that needed to be modified). I couldn't get Joa's Scala code to work, so I ended up implementing his solution in Java.

1. Download binaries.
2. Make sure Scala is installed (the libraries are still required, even though the solution is in pure Java).
3. Compile and run the code below using the appropriate classpath (pointing to the folder with Apparat binaries as well as your Scala libraries).
   1. javac -classpath ".;apparat/*;C:/path/to/scala/lib/*" SwfEditor.java
   2. java -classpath ".;apparat/*;C:/path/to/scala/lib/*" SwfEditor

import apparat.swf.Swf;
import apparat.abc.Abc;
import apparat.swf.SwfTag;
import scala.collection.Iterator;
import scala.Symbol;
import apparat.swf.DoABC;

class SwfEditor {

  public static void main(String[] args){
    Swf input = Swf.fromFile("in.swf");
    Iterator<SwfTag> iter = input.tags().iterator();
    while (iter.hasNext()) {
      SwfTag tag = iter.next();
      if(tag instanceof DoABC) {
        DoABC doABCTag = (DoABC) tag;
        Abc abc = Abc.fromTag(doABCTag).getOrElse(null);
        Symbol[] strings = abc.cpool().strings();
        for(int i=0; i<strings.length; i++) {
          String string = strings[i].toString();
          if(string == "'search")) {
            strings[i] = new Symbol("replacement");
          }
        }
        abc.write(doABCTag);
      }
    }
    input.write("out.swf");
  }
}
