The world came to a standstill after a technology outage reported Thursday evening grounded airplanes, disconnected hospitals and shut down banks across the globe. A faulty software update was to blame, not cybercriminals, but Florida Tech assistant professor TJ O’Connor said the outage’s cascading effect points to larger concerns about our society’s reliance on the internet.


The outage, which affected users’ ability to access Microsoft 365 applications, was traced back to a defect found in a software update from cybersecurity company CrowdStrike. CrowdStrike quickly released a statement confirming that the outage was “not a security incident or cyberattack.”

The outage was nonetheless damaging, kicking institutions offline. Issues remained more than a day later.


“Once those services go down, there’s this massive cascading effect,” O’Conner said. “If bank processing doesn’t work, then aviation doesn’t work. If aviation doesn’t work, shipping doesn’t work.”


Ultimately, O’Connor explained, the biggest concern isn’t the glitch in the system; it’s the number of systems that broke because CrowdStrike wasn’t working.


“I think what we’ll see a lot of people learn from this CrowdStrike incident is…that if they want to take the internet down in the future, all they have to do is hit one target,” O’Connor said. “It makes the threat landscape a lot smaller to attack for an adversary.”


Over the course of several hours, a blue Microsoft error screen taunted companies worldwide. Airlines including Delta, American and Frontier grounded all flights. Several television news outlets, including the United Kingdom’s Sky News, were unable to hold live broadcasts.


Some of the biggest concerns lie in the hospital industry, where planning, evaluation and continuous monitoring are essential, O’Connor noted.


“[Hospitals] are constantly processing so much data, and for them to go out for a couple of hours means that decisions aren’t being made on an automated basis,” O’Connor said. “We’ve kicked over so much of our decision making to automated systems that we can’t let those networks fail.”


According to the United Kingdom’s National Health Service (NHS), the outage disrupted its appointment and patient record system. Mass General Brigham in Boston, Massachusetts was also one of several U.S. hospitals that cancelled non-urgent surgeries, procedures, and medical visits because of the disruption.


911 outages were also reported in several states, including Phoenix, Arizona, whose computerized dispatch center was affected, the police department posted on social media. In Portland, Oregon, Mayor Ted Wheeler issued a citywide state of emergency due to the outage’s impact on city servers, computers and emergency communications.


Although CrowdStrike confirmed the incident was not malicious, O’Connor said it raises questions about overall reliance on the internet to make decisions, as well as ineffectiveness in securing it.


“We continually have these wake-up moments where something happens, it’s large scale, it’s a news blip, and then we forget about it… but our adversaries don’t,” O’Connor said. “Unfortunately, the attack infrastructure and the ability to attack is getting easier and easier.”


O’Connor also expects future network attacks to get worse, calling the unstable global environment a “national-level issue to address.”


While large-scale attacks and outages are mostly out the individuals’ control, O’Connor said, people can take action to protect themselves from personal cybersecurity attacks by using multi-factor authentication as much as possible.

Covering the Tragic Crash in Washington - Our Experts Can Help

The shocking news of an in-air collision in Washington has garnered massive attention from media, airline authorities and industry experts. Reporters covering the story - rely on experts.  And that's where's Florida Tech's Shem Malmquist was called to lend his expert perspective, insight and opinion on a story that's making international news. "It just shows that traffic is in our location, there's a potential collision hazard," said Shem Malmquist, a pilot and visiting instructor of general aviation and transport aircraft at the Florida Institute of Technology. And in certain situations, it will provide guidance for the pilots on how to avoid a collision, he said. For example, if TCAS believes the pilot needs to pay attention to other air traffic in the area, it may say "traffic traffic," Malmquist said. January 30 - CBC News Shem Malmquist, who is a pilot and instructor at the Florida Institute of Technology, said midair collisions are extremely rare. Malmquist said if they happen they normally happen at smaller airports without air traffic control towers like the Lantana Airport. "The only method of separating traffic is visually, as well as airplanes communicating their positions to other airplanes, and that's going to create more risk," Malmquist said. January 30 - WPTV/NBC News American Airlines Flight 5342 and a military helicopter collided mid-air late Wednesday night near Ronald Reagan Washington National Airport. Officials believe all 64 people aboard the airplane -- 60 passengers, 4 crew members -- and the three people aboard the helicopter are dead. Officials conducted a frantic rescue effort overnight, which transitioned to a recovery effort early Thursday. Many aboard the plane were in Wichita, Kansas for a figure skating competition. Captain Shem Malmquist, an aviation expert at Florida Institute of Technology, joins FOX 35 to talk more about what happened. January 30- Fox News Orlando Looking to connect with Shem Malmquist regarding this ongoing story?

Florida Tech’s Pallav Ray Seeks to Improve Accuracy of Rainfall Predictions During Monsoon Season

Growing up in Kolkata, India, Pallav Ray recalls hot spring days leading up to summer’s monsoon season. Temperatures sat above 35 degrees Celsius (95 degrees Fahrenheit), rarely falling below that. When it rained, however, that’s when he could find relief – often by walking barefoot on the cool ground. Now an associate professor of ocean engineering and marine sciences at Florida Tech, Ray studies tropical climate dynamics and their variability using observations, models and theory. His paper, “Rain‐Induced Surface Sensible Heat Flux Reduces Monsoonal Rainfall Over India,” was published in Geophysical Research Letters and highlights research he said was inspired by his childhood in India’s hot climate. His research, funded by the National Oceanic and Atmospheric Administration (NOAA), found that including a variable that is often neglected by climate models could improve the accuracy of rainfall predictions. In turn, that could help agriculture industries better prepare for regional irrigation and flooding during monsoon season. Ray’s climate modeling research spans across the globe, from India, to Chicago, Ill., and most recently the Indo-Pacific Maritime Continent archipelago, which includes countries such as Indonesia and New Guinea. The variable, notated as “Qp,” represents precipitation-induced sensible heat flux, which is a component of surface energy that influences precipitation. It essentially accounts for how precipitation cools land surface temperatures. Qp is calculated using a formula accounting for the specific heat of rainwater, density of rainwater, the rate of rain, surface temperature and the temperature of raindrops when they hit the surface. This variable is important, Ray explained, because the temperature of raindrops is typically cooler than the temperature of the surface, so when it rains, the surface cools down. During monsoon season, land is warm and the ocean is cooler, which pushes moist air from the ocean to the land. The higher the temperature difference between the land and the ocean, the stronger the monsoon because it brings more moisture, Ray explained. In testing Qp, Ray and his team of researchers ran simulations investigating the variable’s role on precipitation. They found that when incorporating it, not only is anticipated precipitation reduced by up to 5% – which he says is a significant reduction – but the models also reflect changes in the spatial distribution of precipitation. “The moment we include that term, it cools down the surface, land surface. The temperature difference is smaller between the land and the ocean,” Ray said. “That reduces the overall precipitation overland because now less moisture is coming from the ocean.” In India, Ray explained, most models, overestimate precipitation. His results generated predictions that were much closer to observed rainfall. He says that inclusion of this variable in common climate models could influence India’s regional agriculture and irrigation strategies. According to Ray, rainfall is closely tied to the India’s industries, especially agriculture. He said the variable may have the greatest impact on seasonal rainfall predictions, which happen months in advance and determine how the country approaches its agricultural practices. Policymakers rely on seasonal rainfall predictions to anticipate and plan for summer monsoons, and the money allocated to deal with excess rainfall is “tremendous,” he said. “If you can do a seasonal prediction a few months in advance and your precipitation actually changed by 5%, it’ll change whether you’ll have an excess year versus you’ll have a deficit year,” Ray said. “I think that’s where the main, major impact is.” In his future research, Ray would like to explore how Qp would impact climate models over urban areas here in Florida.
