Incident Handler's Journal

I recently learned of a security incident that occurred at a small U.S. healthcare clinic specializing in primary care services. The incident took place on a Tuesday morning, at around 9:00 a.m., and had significant consequences for the clinic's operations. Numerous employees reported an inability to access crucial files, including medical records, via their computers, which led to a complete shutdown of business operations.

Furthermore, employees also discovered a ransom note displayed on their computer screens. This note conveyed that all of the clinic's files had been encrypted by an organized group of unethical hackers who are notorious for targeting organizations in the healthcare and transportation sectors. In return for restoring access to the encrypted files, the ransom note demanded a substantial sum of money in exchange for the decryption key.

The attackers managed to infiltrate the clinic's network by executing targeted phishing email campaigns. These emails were sent to multiple employees within the organization, and they contained a malicious attachment. Once downloaded, this attachment installed malware on the employees' computers, providing the attackers with a gateway into the network.

Upon gaining access, the attackers deployed their ransomware, encrypting critical files. As a result, the clinic was unable to access vital patient data, causing significant disruptions to their business operations. Subsequently, the clinic had no choice but to shut down their computer systems and contact various organizations to report the incident and seek technical assistance.
