The Florida Water Treatment Plant was hacked and the attacker managed to increase the amount of Sodium Hydroxide levels from 100 parts per million to 11,100 parts per million. The attacker was able to compromise the remote access system and managed to change parameters for the lye component. This is the worst case scenario for Industrial Control Systems which could have led to a dangerous situation. An operator was able to spot the increase in levels and was able to turn it down.

Google bans the Spanish Certificate Authority (CA) -Camerfirma. CAs In cryptography are certification authority is an entity that issues digital certificates. While this is nothing new, in the past major browsers have issued warnings and requested CAs to fix issues with verification and validation of certificates. The result is that the websites and services that use certificates that were issued by Camerfirma will start to get flagged on Chrome browsers and will start showing a Certificate Error with the release of the new browser version Chrome 90 which will be available in April of 2021.

Facebook etiquette:
I am always keen to learn more about how one can improve our interactions and behaviors that can benefit the society as a whole. When it is really at a click of a button you can send communication across the wire and increasingly with very little thought or consequence. As today is Safe Internet Day, I wanted to feature an article written by ESET security blogger Amer Owaida. He very beautifully outlines some of the strategies to apply to strengthen your privacy, security and most importantly to remember the famous Vegas Line, what happens on the internet stays on the internet. Link is in the show notes.
