The attack began by infecting computers through this vulnerability and then quickly spread through network connections, targeting additional systems.

Effects and Response to the WannaCry Attack

The ransomware WannaCry attack caused significant financial and reputational damage to many organizations. Companies worldwide had to deal with data loss, operational disruptions, and the need to pay a ransom to regain access to encrypted files.

The swift response of cybersecurity companies and international cooperation led to halting further spread of WannaCry and developing tools that allowed victims to recover data without having to pay the ransom.

Summary

Ransomware WannaCry was one of the most damaging ransomware attacks in history, highlighting the importance of regularly updating systems and safeguarding data. Following the WannaCry attack, many organizations increased their protective measures and investments in cybersecurity to avoid similar incidents in the future.
