A Canadian technology analyst says the incident shows the nearly "universal" use of Windows products for key digital infrastructure highlights how quickly security issues can start to cascade.

"It's so universal, so common, the impact is much wider than would normally be the case." Carmi Levy, a Canadian technology expert, told CTV Your Morning's Anne-Marie Mediwake on Friday. "We're talking about companies all around the world."

The software detects and blocks hacking threats, but like other cybersecurity products, it requires deep-level access to a computer’s operating system

"The irony is they're a cyber security company… they certainly didn't provide a lot of security here," says Levy.

The global cyber outage that caused disruptions to airlines, businesses and emergency services on Friday could be the “largest IT outage in history,” according to cybersecurity expert Troy Hunt.

“I don’t think it’s too early to call it: this will be the largest IT outage in history,” Hunt said in a post on X on Friday.

“This is basically what we were all worried about with Y2K, except it’s actually happened this time,” he added.

Other recent large outages:
  • It remains to be seen whether the scale and impact of the outage will reach the level of the “NotPetya” cyberattack in 2017, which the Kremlin was widely considered to have been behind. The 2017 attack initially targeted computers in Ukraine but affected companies globally. The White House upbraided Russia for “the most destructive and costly cyber-attack in history.”
  • There was another mass internet outage in 2021 across the world, following a bad software update by Fastly, a company which runs a content delivery network of servers and data centers.
  • In January 2023, a computer outage at the US Federal Aviation Administration caused thousands of canceled or delayed flights but did not directly affect other sectors. The FAA said at the time that they had traced the fault “to a damaged database file” and that there was “no evidence of a cyberattack.”
  • Last month, a systems outage at software provider CDK Global, which the company says was caused by a cyberattack, resulted in chaos at car dealerships in the US, making it difficult for it to track customer interactions, orders and sales. Sources told CNN that CDK Global appeared to have paid a $25 million ransom to the hackers in order for the outage to end.
 
I remember when the calendars were all about to flip to the year 2000, and the massive IT precautions and backups that had to be done in case the systems collapsed. Y2K it was called.

We put in tons of overtime hours at the place I was working, just to get ready. (Then nothing adverse happened. :D )
I remember Y2K very well too as I worked a 13 hour shift on Y2K at work.

Everything ran fine and nothing crashed at midnight on Y2K.

God I hope there's no fatalities and this doesn't happen again.
This is giving me flashbacks to 2022 (my fellow Canadians will know) of a massive tech outage we had nation-wide.
We lost internet, cable, public transportation, government services, debit machines, traffic lights, fire alarms/sprinkler systems, and 911 services.. and someone did die. It took 2 days to resolve this little maintenance whoopsie... apparently they've put solutions in place finally (almost the same thing happened a year prior) but I guess we will just have to wait and see what happens when another software update goes wrong.


BBM. Having worked in IT myself I can understand how an error can be made and an update can go wrong and get out. What I find harder to understand is how it can be rolled out across the world in that state. In my day it was all about testing, and rolling updates out in controlled phases, so these things things got picked up before they affected the whole company. JMO.
 
That happened to me last night at work. My work computer screen went completely blue, and crashed. Fortunately, I am not working in a control tower at LAX!!! How crazy would that have been!

It was about 10:20 MDT for me, I rebooted, and got back on in about 10 minutes.

Crazy enough, IT states it was an update from "Crowdstrike" a vendor system used to protect computer systems from "malware". LOL. To prevent stuff like this from happening

Known as a BSOD - blue screen of death. Surprised a reboot fixed it - I thought there was more involved to recover each computer?
 
“This is a very, very uncomfortable illustration of the fragility of the world’s core Internet infrastructure,” said Ciaran Martin, professor at Oxford University’s Blavatnik School of Government and former head of the UK National Cyber Security Centre. While the core problem appeared simple, which should make it short-lived, its immediate impact was remarkable, Martin said.

“I’m struggling to think of an outage at quite this scale.”

Yeah. I don't know, I took a picture of my screen, mailed it to my supervisor from my phone. Logged back in, clocked out, turned off my computer. I didn't try to work after that, my shifts ends at 10:30.

It's a bit re-assuring how fast everything seems to be recovering, though. What I'm hearing now is not about outages but how things are getting back to functioning mode.

A similar thing happened at my workplace today. IT recommended that we reboot and that should fix the issue. It worked for me but not my in-office coworker. Also didn't work for the handful people who keep hitting "reply-all" to the IT email.

IIRC, it was Rogers customers who lost access.

We use Telus and Teksavvy for internet so were good to go.

At the time, we also had a land line with Bell so still had emergency services.

Bell has since removed all copper wired phones, so emergency services would be lost.

Many people I know were convinced to have two phones, each with different providers, after this fiasco.
