How does it spread?
According to the US Computer Emergency Readiness Team (CRT), under the Department of Homeland Security, ransomware spreads easily when it encounters unpatched or outdated software. Experts say that WannaCry is spread by an internet worm — software that spreads copies of itself by hacking into other computers on a network, rather than the usual case of prompting unsuspecting users to open attachments. It is believed that the cyber attack was carried out with the help of tools stolen from the National Security Agency (NSA) of the United States.
Some forms of malware can lock the computer entirely, or set off a series of pop-ups that are nearly impossible to close, thereby hindering your work.
