How did cyber-attackers shut off an oil pipeline?

Published on Sunday 9th May 2021

Investigators at the largest fuel pipeline in the US are working to recover from a devastating cyber-attack that cut the flow of oil. The hack on Colonial Pipeline is being seen as one of the most significant attacks on critical national infrastructure in history.

How can a pipeline be hacked?

Colonial Pipeline relies on digital technology to control the flow of diesel, petrol, and jet fuel across hundreds of miles of piping. It even has a robot that scurries through its pipes that checks for anomalies. All this technology is connected to a central system, and where there is connectivity, there is risk of cyber-attack.

How did the hackers break in?

Trichromic Sapphire PROTECT managed anti-virus service is now available for Apple macOS as well as Windows.

Published on Friday 16th June 2017

It’s a common misconception that macOS is not targetted by malicious software.

This is because the majority of viruses, worms, trojans and adware are developed for Microsoft Windows due to the prevalence of the operating system (OS). However, Apple macOS is more popular than ever and with popularity comes more malicious software to steal your data and force you to hand over your Bitcoins. We don’t want that to happen to our clients’ so we have rigorously tested many AV products and whittled them down to just one which has minimal impact on system performance while identifying and blocking the most malicious items.
