The largest cyberattack in U.S. History?

Over the past weekend, chaos erupted and Universal Health Services experienced what could be now potentially the largest cyberattack in United States history, affecting more than 400 hospitals by causing their computer systems to fail, prompting employees to fill out patient information manually with pen and paper. While Universal Health Services itself did not respond to allegations, those familiar with the company security and response issues mentioned that the outage "looks and smells like ransomware." 

Two other employees of Universal Health Services commented that the attack had begun over the weekend and caused delays and hardships in the work of employees. The cyberattack could have been much worse, as in the past patients have suffered and even died due to an indirect result from cyber attacks launched at hospitals around the world. Luckily, at this time it appears nobody has past away due to the malicious behavior that may be taking place across the Universal Health Services computer network. 

Medical data and information is critical to have at any given moment as it may make a difference in saving one's life, and thus it is also critical to have the highest security available for computer networks which have such delicate and necessary information to prevent attacks such as this one. Otherwise, the impact could be more severe and in some cases, even fatal.
