"Hospitals, school districts, state and local governments, law enforcement agencies, small businesses, large businesses-these are just some of the entities impacted recently by ransomware, an insidious type of malware that encrypts, or locks, valuable digital files and demands a ransom to release them. The inability to access the important data these kinds of organizations keep can be catastrophic in terms of the loss of sensitive or proprietary information, the disruption to regular operations, financial losses incurred to restore systems and files, and the potential harm to an organization's reputation. And, of course, home computers are just as susceptible to ransomware, and the loss of access to personal and often irreplaceable items-including family photos, videos, and other data-can be devastating for individuals as well. […] So what does the FBI recommend? As ransomware techniques and malware continue to evolve-and because it's difficult to detect a ransomware compromise before it's too late-organizations in particular should focus on two main areas:  Prevention efforts-both in both in terms of awareness training for employees and robust technical prevention controls; and  The creation of a solid business continuity plan in the event of a ransomware attack."
