To Patchnya, or Not to Patchnya


Heads-up: there's another ransomware worm making the rounds. Initially thought to be a variant of the Petya ransomware family, it was later determined to be something entirely different, and has been dubbed "NotPetya" in many tweets and reports.

Like the WannaCry worm that made such a splash in May, it exploits a (now-patched) vulnerability in the Windows file sharing protocol known as SMB. Unlike WannaCry, it also harvests credentials from compromised systems, then uses standard Windows administration tools such as WMIC and psexec to spread within an organization.

Whois David?

I have spent the better part of two decades in information technology and security, with roots in application developer support, system administration, and network security. My specialty is cyber threat intelligence - software vulnerabilities and patching, malware, social networking risks, etc. In particular, I strive to write about complex cyber topics in a way that can be understood by those outside the infosec industry.

Why do I do this? A common comment I get from friends and family is that complex security topics give them headaches. They want to know in simple terms how to stay safe in a connected world. Folks like me and my peers have chosen to make a profession out of hacking and defending. I've been doing this for the better part of two decades, and so have a high degree of knowledge in the field. Others have chosen different paths - paths where I would be lost. This is my effort to share my knowledge with those that are experts in something else.

When not in front of a digital screen, I spend my time raising five rambunctious teens and pre-teens - including two sets of twins. Our family enjoys archery, raising show and meat rabbits, and simply enjoying life in the Texas hill country.

For a decade I served as either Commander or a division leader for the Awana Club in Dripping Springs, Texas; while I have retired from that role I continue to have a passion for children's ministry. At the moment I teach 1st through 3rd grade Sunday School. Follow FBC Dripping Springs Kids to see what is going on in our children's ministries.
