A software failure on Friday caused airlines, banks, and supermarkets in the USA to be paralyzed, resulting in flight cancellations. This failure seems to have been global, affecting millions of systems in Australia and beyond, and appears to have been related to cybersecurity provider CrowdStrike and its software called "Falcon". CrowdStrike provides software for thousands of companies worldwide to resist viruses and cyberattacks. The failure caused Microsoft laptops and personal computers to display the "blue screen of death", preventing employees and customers from accessing their systems. Although Microsoft was not the source of this attack, Falcon software is used for Microsoft's Windows systems, not Apple's MAC computers. Microsoft says it is investigating the incident. Currently, such failures are relatively common, with telecommunications companies, banks, and supermarkets often experiencing technical glitches that usually last for several hours. However, a failure on this scale may have never been seen before, highlighting the extent of our modern economy's dependence on technology and the increasing degree of interconnectivity.
