I believe a lot of "Steemians" use the Linux operating system. This video by Computerphile, reveals the "Dirty Cow Exploit", what it is and how to fix the problem. Every user of Linux is vulnerable to having anyone use this exploit to gain root directory access. Being such a critical security flaw in Linux, I was hoping to spread awareness to all the "steemians" so they would not be vulnerable. I thought this video was an important video for steemit users to see so I uploaded it to my blog. I am not the creator of this video, the absolutely excellent Youtube channel Computerphile made this video. Thanks for viewing this post and I hope you enjoyed the video!
