Ransomware infections are on the rise, and healthcare organizations are ripe targets, which may be why the federal government addressed the subject last week. Ransomware attacks have risen from about 1,000 a day last year to 4,000 a day this year, Symantec has reported. Many of those attacks are for small change, but some of the larger ones have been directed at healthcare providers. For example, Hollywood Presbyterian Medical Center earlier this year paid hackers $17,000 to get its systems back online.
