WannaCry Ransomware (2017)

Impact & Aftermath

What were the consequences for companies, individuals, or society?

• Companies:Disruption of operations, financial losses, and reputational damage. For example, the UK NHS had to cancel thousands of medical appointments and surgeries.
• Individuals:Personal files were encrypted, and those who paid the ransom often did not regain access to their data.
• Society:Global awareness of the risks associated with outdated and unpatched systems increased.

How did the affected company/government respond?

Microsoft quickly released emergency patches for unsupported versions of Windows (e.g., Windows XP). Governments and organizations worked to contain the spread by isolating infected machines and applying patches. A cybersecurity researcher, Marcus Hutchins, accidentally discovered a kill switch in the malware’s code, significantly reducing its spread.

What security measures were implemented afterward?

Organizations were urged to:

• Regularly update and patch systems.
• Implement robust backup and recovery plans.
• Train employees to recognize phishing attempts.
• Governments and agencies improved threat intelligence sharing to combat similar attacks.

Did the hack lead to new laws, policies, or security changes?

• New Policies: Several governments strengthened national cybersecurity policies and strategies. Organizations worldwide emphasized compliance with cybersecurity frameworks like GDPR (General Data Protection Regulation) and NIST (National Institute of Standards and Technology) guidelines.
• Laws: Some countries introduced stricter regulations around maintaining software updates and reporting breaches.
• Awareness: The attack highlighted vulnerabilities in critical infrastructure, prompting global conversations about cyber resilience.
