Windows Phone Xap Archive Verified |best| -

A (Gold standard) means: The XAP file has been cryptographically hashed (SHA-256), the hash is recorded in a public ledger, the package deploys onto a factory-reset Lumia 930, and the certificate chain traces back to either Microsoft or the original developer. How to Verify a XAP File Manually (The Hobbyist Guide) If you have downloaded a questionable XAP from a forum, do not deploy it immediately. Follow this manual verification process: Step 1: Inspect the File Header Use a HEX editor (HxD) or 7-Zip. Open the XAP. A valid XAP starts with PK (50 4B).

Malware Injection (The Hidden Payload) Because XAP files are ZIPs, malicious actors can inject .exe or .ps1 scripts into the archive.
