Microsoft faulted over cyberattack

In 2014, Microsoft ended support for Windows XP arguing that the software was out of date

There's a blame game brewing over who's responsible for the massive cyberattack that infected hundreds of thousands of computers. Microsoft is pointing its finger at the US government, while some experts say the software giant is accountable too.
 
The attack started Friday and has affected computers in more than 150 countries, including severe disruptions at Britain's National Health Service. The hack used a technique purportedly stolen from the US National Security Agency to target Microsoft's market-leading Windows operating system. It effectively takes the computer hostage and demands a $300 ransom, to be paid in 72 hours with bitcoin.
