The alert stated malicious groups are targeting the public healthcare sector with the purpose of "data theft and disruption of healthcare services".
Ransomware is an specific attack on systems, servers and networks to scramble data and to literally hijack the data until the clients pay up. It may be found on personal PCs as an individual pop-up stating your computer has been infected and to "click here" to remove the infected file.
However the moment you click on the pop up, a file lurking in the background starts scrambling and locking your data. The pop-up then gives you a notice to contact a phone number to remove the so called "infected" files..... which in reality your paying for tech support to unlock your files...... it's a very evil scheme.
Since the early 2000s, groups have been deviating from private individuals to targeting larger corporations for bigger pay. Major corporations (Norsk-Hydro/Lockergoga in 2019) and entire city governments (Atlanta/SamSam in 2019) have been attacked by ransomware.
A total of 59 U.S. health care providers or systems have been impacted by ransomware in 2020, disrupting patient care at up to 510 facilities.
The alert was posted so healthcare providers, IT and network administrators, can take necessary steps to protect their networks from such attacks.
