Note: Password to zip file is false-positive.
The BitStak Ransomware will encrypt your files, scramble their filenames, and then add the .bitstak​ extension to encrypted files. For example, the file "Penguins.jpg" may be renamed "xfZdSbZU.aXd.bitstak". This tool will allow you to decrypt your files and rename them back to their original names.
