Hackers attempt attacks like this all the time. Most of these are, thankfully, thwarted by cybersecurity efforts. However, even with adept cybersecurity experts on the job, more and more of these kinds of hacks are bound to occur. Hackers like the challenge of infiltrating seemingly strong networks. And, most importantly, there is a lot of money to potentially be had.
While it can't help for normal citizens to dwell on such things everyday, this high-profile attack on the Colonial Pipeline highlights just how vulnerable our infrastructure can be. Hopefully, other companies take note and take action to strengthen their network fail safes and security.
