Looking Back – 4-16-21

 Nearly every morning I start my computer time by looking at information from Google about what happened in my blog in the previous 24 hours. Google, and blogspot.com is a Google service, provides interesting pieces of analytical data about my blog readership. One item of particular interest is the top ten blog posts each day. As you would expect, most of those posts were from the last couple of days, but with 16 years of publishing this blog, every once-in-a-while, a blog post from ancient history rises into that list. 

Today, a blog post from March 16th, 2021, CISA Publishes CFATS Cybersecurity Letter, made the list. It briefly discusses a notification letter that the CFATS folks sent out to chemical facilities about widespread exploitation of the Microsoft Exchange Server Vulnerabilities. The interesting thing was that CISA sent that letter to not just the 3,000+ CFATS regulated facilities, but also to over 33,000 other chemical facilities that had sent Top Screen information to CISA. The odd thing was that the letter was little more than a warning about the vulnerabilities and only recommended that facilities report “evidence of threat actor activity”.
