          There are two reasons such zip files are password-protected:




          1. Someone doesn't want you to have access to it.


          2. To bypass spamware/malware filters. In this case, the bypassing makes it suspect. A quick google search indicates there are plenty of firmwares out there from official sites. Why do they password-protect the firmware?? Hrm.



          The password mechanism on zip files is not cryptographically secure. Brute-force password crackers should do the job in a day at most. Apparently there are several for that task.
