You ran dumpcap as root (or you ran tshark as root, and *it* ran dumpcap, so dumpcap also ran as root), so the file it creates is owned by root, group root, and root probably has a umask of 0026 or 0027, so, by default, files are created with group write permission, and *all* other permissions, turned off.
