i have written a go commandline tool to extract the exe from the gif file as used by this malware.
As a sample input file you can use SHA1:724fa6b4a6a9cff08cae34cc079ef70d80378b32 the resulting exe file should be SHA1:83f7ce3f6c0a7a92d9b225eb6a2953b761601c58. Both files are available from VirusTotal.
You can download the sample gif with the hidden exe also locally. Use infected
as a password for the zip file.
