Today, yet another security blunder becomes publicized, and it is really bad. You see, many Western Digital My Cloud NAS drives have a hardcoded backdoor, meaning anyone can access them — your files could be at risk. It isn’t even hard to take advantage of it — the username is “mydlinkBRionyg” and the password is “abc12345cba” (without quotes). To make matters worse, it was disclosed to Western Digital six months ago and the company apparently did nothing until November 2017. Let’s be realistic — not everyone stays on top of updates, and a backdoor never should have existed in the first place.
