NHS (National Health Service) Digital recently confirmed that the recent NHS cyber attack used the Wanna Decryptor ransomware to infect the systems of at least 24 UK trusts. The attacks are being blamed on a piece of malware called WCry, WannaCry or Wana Decryptor, alleged to have been stolen from the National Security Agency.
It is said that attack will hit both the private and public sectors. Since Friday, more than 200,000 victims in around 150 countries have been infected by the ransomware which originated in the UK and Spain on Friday before spreading globally. Europol’s chief has warned the threat of the cyber attack which took down international services “will continue to grow” when people return to work on Monday.
The attacks appeared to be the largest ransomware assault on record, but the scope of the damage was hard to measure. It was not clear if victims were paying the ransom, which began at about $300 to unlock
