Microsoft had patched the vulnerability exploited in WannaCry attacks with the March 2017 Patch Tuesday cycle, so all systems running Windows 7, Windows 8.1, and Windows 10 were already secure when the WannaCry ransomware dropped bombs on unsuspecting systems last week.

In Windows XP these numbers are not deleted from the computer's memory at the end of the process, although they can be overwritten. Low-end criminals take advantage of less-savvy users with such known viruses, even though malware is constantly changing and antivirus is frequently days behind detecting it. "One should avoid clicking on unknown and suspicious download links", the SP added. Overworked systems administrators work within limited budgets. This helps limit the spread of ransomware if hackers do get into your system. On Friday, it reported 16 computer networks were shut down. Unfortunately, the only source for identifying the attack seems to be a single source - so, in other words, beware what you hear about it. There's also no guarantee all files will be restored. Certainly, organizations that can keep their software updated should do so.

Still, "My answer is, never pay the ransom", Abrams said.
