1/ As users of Wordfence for security of WordPress sites we own or prepare, we appreciate the information shared by the Wordfence team regarding port vulnerabilities of some home routers due to port 7547 being left open. This is sometimes known as the “Misfortune Cookie”, or the MC vulnerability. Use the above noted page’s “SCAN ME” link to check that port in your router.

There is further information on the Misfortune Cookie here, including J.D’s comment that the attacks MC proliferates are “dictionary attacks”, which can anyone can easily block with strong passwords avoidance of “Admin” or use of any other common names for your login user name. Although the resulting attacks are not actually brute-force type, it is absolutely essential for you to assure that your port 7547 is not open. If it is, call your ISP immediately, and have this rectified.
