The recent WannaCry ransomware attack, which spread to more than 100 countries, is only the beginning in a series of similar attacks, according to Cătălin Coșoi, head of the Bitdefender's investigation team coordinating the relations of the company with institutions such as NATO, Europol, Interpol, or national response centers to cyber-security incidents, Agerpres reported.
British health minister Jeremy Hunt said on Monday it was "encouraging" that a predicted second spike of attacks had not occurred, but the ransomware was a warning to public and private organizations. Run Windows Update and get those patches.
Microsoft president and chief legal officer Brad Smith said on Sunday: "We have seen vulnerabilities stored by the Central Intelligence Agency show up on WikiLeaks, and now this vulnerability stolen from the NSA has affected customers around the world".

"Most people are not paying this, so there are not a lot of money being made with this by criminal organisations so far", he said. By late morning, some people were still filling out forms manually, but the hospital said 70 percent of systems were back online.

Though the ransomware continued to spread at a more subdued pace on Monday, many companies and government agencies were still struggling to recover from the first attack.More news: Senate $40.3 billion budget plan keeps tax estimates intact
