Not all that zips is gold. Because Mythroad Zips are user-uploaded and unvetted, they come with inherent risks:

Developed by the Chinese company Spreadtrum, Mythroad is a software engine (a Virtual Machine) designed to run on mobile devices with very limited resources.

Brute force (if weak password):

$ zip2john mythroad.zip > hash.txt
$ john --wordlist=rockyou.txt hash.txt

Often yields password like mythroad or password123.

Known-plaintext attack (if you have one file from the zip): mythroad zip

$ pkcrack -C mythroad.zip -c knownfile.txt -P knownplain.zip -p knownfile.txt -d decrypted.zip

Zip crypto vulnerabilities:
Older ZIP encryption (ZipCrypto Store) can be broken with bkcrack if 12+ bytes of plaintext are known.

There are rumors of a "Mythroad Remastered" launching on Itch.io, which would likely be distributed as a .zip file to avoid platform fees.
