#1482 Invalid SWF Wrong Signature
Hi, I can not open this swf file. can you help me ?
huqzz.swf (27 KiB)
Sorry, this is not an SWF file. Duplicate of #1479 (and many other) There is no way to open it with FFDec when you have this file only. However if you are able to run it somehow, for example there is a loader for that, then maybe you can open it or dump the decrypted version from the memory.
