Ransomware Attack and Data Breach
In 2024, Sun Pharma, one of India’s largest pharmaceutical companies, was hit by a ransomware attack that led to a significant data breach. Hackers gained access to critical data, disrupting internal systems and compromising sensitive information.
Solution
Implemented multi-layered endpoint protection and advanced ransomware detection systems.
Conducted thorough forensic investigations to trace the attack vectors and patched security vulnerabilities.
Deployed a zero-trust architecture to limit access to sensitive systems.
Trained employees on identifying and reporting suspicious activities.
Result
Data was successfully restored from secured offline backups, minimizing operational downtime.
Enhanced monitoring systems reduced the likelihood of future breaches.
A comprehensive incident response plan was developed to strengthen cybersecurity posture.
Data Breach and System Outage
AIIMS, India’s premier medical institution, faced a massive cyberattack in late 2024 that compromised the electronic health records (EHR) of millions of patients. The attack caused a system-wide outage, delaying critical healthcare services and resulting in significant financial losses.
Solution
Migrated critical systems to a secure, hybrid cloud infrastructure with robust encryption.
Introduced multi-factor authentication (MFA) to secure login processes.
Implemented a Security Information and Event Management (SIEM) system to monitor and analyze suspicious activities in real-time.
Conducted regular penetration testing to identify potential vulnerabilities.
Result
Restored systems with minimal data loss and improved response times.
Strengthened access controls and enhanced network monitoring to prevent future attacks.
Achieved improved compliance with data protection regulations, including HIPAA and NDHM (National Digital Health Mission) guidelines.
IoT Device Vulnerabilities and Risk Management
With the rise of IoT-enabled medical devices, Apollo Hospitals encountered security vulnerabilities that exposed devices to potential exploitation by cybercriminals. Hackers attempted to gain control over connected medical devices, risking patient safety.
Solution
Deployed network segmentation to isolate IoT devices and prevent unauthorized access.
Implemented device authentication and continuous vulnerability management to secure device communication.
Established an IoT Security Operations Center (SOC) to monitor and respond to threats in real time.
Educated healthcare personnel on IoT device management best practices.
Result
Significantly reduced the attack surface by securing connected medical devices.
Maintained patient safety through enhanced monitoring and swift threat containment.
Developed a robust risk management framework for IoT security.
Phishing and Email Spoofing Incident
In early 2025, Fortis Healthcare faced a targeted phishing attack where hackers impersonated senior executives to gain access to critical financial and patient data. The attackers used sophisticated email spoofing techniques to deceive employees.
Solution
Deployed an AI-powered email filtering system to detect phishing attempts.
Introduced security awareness training programs to educate staff on recognizing and reporting phishing attempts.
Strengthened Domain-based Message Authentication, Reporting, and Conformance (DMARC) policies to prevent spoofed emails.
Enabled sandboxing for suspicious attachments to isolate and analyze malicious files.
Result
Reduced phishing attempts by over 80%, safeguarding sensitive corporate and patient data.
Increased employee vigilance, resulting in quicker identification and reporting of phishing attempts.
Strengthened email security infrastructure to prevent future email-based attacks.
