Experts quickly advised affected users against paying the ransom due to no reports of people getting their data back after payment and as high revenues would encourage more of such campaigns. February of that year following a tip off about the vulnerability in January of that year. Organizations were advised to patch Windows and plug the vulnerability in order to protect themselves from the cyber attack.

While this did not help already infected systems, it severely slowed the spread of the initial infection and gave time for defensive measures to be deployed worldwide, particularly in North America and Asia, which had not been attacked to the same extent as elsewhere. Within four days of the initial outbreak, new infections had slowed to a trickle due to these responses. NSA memo is alleged to have also linked the creation of the worm to North Korea.

An equivalent scenario with conventional weapons would be the U. The United States Congress will also hold a hearing on the attack on June 15.

Snowden states that when “-enabled ransomware eats the Internet, help comes from researchers, not spy agencies” and asks why this is the case. In addition, Segal said that governments’ apparent inability to secure vulnerabilities “opens a lot of questions about backdoors and access to encryption that the government argues it needs from the private sector for security”.
