The virus has so far infected almost 200,000 computers world-wide.
In India, more than "more than 100 systems of the Andhra Pradesh police department" were affected over the weekend, NDTV reports.
Personally, I know many I.T. Security analysts.
The ransomware covers almost any important file type a user might have on his or her computer.
White House cyber security coordinator Rob Joyce, who previously worked in the NSA's elite hacking squad, told a Reuters reporter in April that the Trump administration was considering how to "optimize" the Vulnerability Equities Process, but he did not elaborate.
"Finally, this attack provides yet another example of why the stockpiling of vulnerabilities by governments is such a problem", Microsoft then said, calling out the Central Intelligence Agency secrets that surfaced on WikiLeaks and the hacking tools stolen from the NSA that led to the WannaCry attack.
"The governments of the world should treat this attack as a wake-up call", Microsoft continued, claiming that they should apply cybersecurity rules similar to the laws governing physical weapons.
For the most part, civil liberties groups are siding with Microsoft.
Ryan Kalember, senior vice president at Proofpoint Inc. which helped stop its spread, said the version without a kill switch could spread.

One source said: "We work with a lot of different people". "One of the country's largest oil companies, PetroChina, reported the attack had disrupted its electronic payment systems at its gas stations over the weekend". Updating software will take care of some vulnerability.
(In China, that country's love of pirated software, which typically doesn't receive updates, contributed to WannaCry's virulent spread there on Monday).
You should make multiple backups - to cloud services and using physical disk drives, at regular and frequent intervals.
This is a problem because India is third only to Russian Federation and China in the percentage of computers running pirated software.
Smith went on to describe the situation as the equivalent of U.S. Tomahawk cruise missiles getting stolen from military stockpiles.
The VNCERT said the ransomware is extremely risky as it is capable of stealing information and decrypting the entire system that has been infected.
