Each release includes a list of file hashes which are sent to the wireshark-announce mailing list and placed in a file named SIGNATURES-x.y.z.txt.Announcement messages are archived at -announce/ and SIGNATURES files can be found at -versions/.Both are GPG-signed and include verification instructions for Windows, Linux, and macOS.As noted above, you can also verify downloads on Windows and macOS using the code signature validation features on those systems.

In fact, SQL injection attacks can be wielded against desktop applications as well. For example, I have included in the download files for this article (available from the link at the top of this article) a sample Windows® Forms application named SQLInjectWinForm that is also susceptible to SQL injection attacks.
