WannaCry is a type of ransomware that caused a major global cybersecurity crisis in May 2017. The virus spread quickly through computer networks and targeted systems that used outdated versions of Windows. Once a computer was infected, the virus locked the files and demanded payment in digital currency. Many organizations were caught unprepared which led to widespread disruption.
How WannaCry Spread
The attack used a security flaw in Windows that allowed the virus to enter computers without permission. This flaw was linked to a leaked tool created by a government agency, which made the spread even faster. Countries around the world reported thousands of infections within hours. Hospitals, companies, schools, and government offices were among the victims which made the outbreak one of the most damaging cyberattacks in history.
What happened if the WannaCry ransom was not paid
When the WannaCry ransom was not paid, the encrypted files stayed locked. The attackers first demanded 300 dollars worth of bitcoins and later raised it to 600 dollars. They warned that files would be deleted after three days. Many victims chose not to pay and had to restore their systems from backups or reinstall everything. This caused delays in work and service interruptions. Some had no backups and lost their data permanently. The event proved that payment did not guarantee recovery and that good backup plans were the safest protection.
The Deadly Impact
WannaCry forced many institutions to shut down computers completely to avoid further infection. Hospitals in the United Kingdom had to cancel appointments and redirect patients. Factories stopped production to protect their networks. The financial damage reached hundreds of millions of dollars. The attack showed how dangerous outdated software can be when security updates are ignored.
How did we stop the outbreak?
Cybersecurity experts worked together to slow down the spread of the virus. A researcher discovered a kill switch hidden in the code which helped stop the attack from getting worse. Microsoft also released emergency security updates for older versions of Windows to protect users. These actions reduced the number of new infections and helped many systems recover.
Lessons Learned from WannaCry
WannaCry became a strong reminder that cybersecurity is important for everyone. Organizations must install updates regularly to prevent attacks. Backup data must be stored safely so files can be restored without paying criminals. The event pushed governments and companies to take security more seriously and to prepare better for future threats.
