[QUOTE="Hormoz, post: 1039613, member: 82841"] Microsoft allows you to sign an executable, and has a list of certificates to validate those signatures. However it is possible to change the data on a file, while still passing the signature check, allowing you to add or change data in certain parts of it. Does this pose any security risk? Quoting from an [URL='https://blog.barthe.ph/2009/02/22/change-signed-executable/']old blog post[/URL] (which is still relevant): [/QUOTE]
