These attacks have left people puzzled. So, what exactly happened? what actually is this ransomware cyber attack? Here are all your questions answered:
– Ransomware is a type of malicious software that infects a computer and restricts users’ access to it until a ransom is paid to unlock it.
– According to a report by PTI, the software demands a ransom of 300 dollars from each user. However, this amount has to be in cryptocurrency Bitcoin to retrieve their files.

– The malware was made available online on April 14 through a dump by a group called Shadow Brokers, which claimed last year to have stolen a cache of “cyber weapons” from the National Security Agency (NSA). At the time, there was scepticism about whether the group was exaggerating the scale of its hack.
