The Crucial Lesson of Data Backups: Protecting Your Business from Ex-Employee Sabotage

Importance Of Backups To Prevent Ex-Employee Sabotage

As recent events have shown, even the most robust systems can be vulnerable to internal threats, particularly from unhappy former employees. The recent case of Kandula Nagaraju, a 39-year-old former employee of NCS who deleted 180 virtual servers after being terminated, underscores the critical importance of maintaining comprehensive and up-to-date backups.

The Incident: A Cautionary Tale

Kandula Nagaraju, feeling confused and upset after being fired from his position at NCS, accessed the company’s computer test systems unauthorizedly and deleted 180 virtual servers. This act of sabotage resulted in a staggering financial loss of S$918,000 (approx. 5.66 crore INR) for the company. Nagaraju, who believed he had performed well during his tenure, was terminated due to poor work performance and returned to India without securing another job in Singapore.

Despite the termination of his contract, Nagaraju still had access to the system and used his administrator login credentials to log in from his laptop multiple times between January and March 2023. His actions, motivated by a sense of injustice, culminated in the deletion of critical virtual servers, severely disrupting NCS’s operations.

The Aftermath: Financial and Operational Impact

The deletion of 180 virtual servers crippled NCS’s quality assurance (QA) computer system, used for testing new software and programs before launch. The company’s team quickly realized the gravity of the situation when they found the system inaccessible and their troubleshooting efforts futile. An internal investigation revealed that the servers had been deliberately deleted, leading to a police report and subsequent seizure of Nagaraju’s laptop, which contained the malicious script he used.

The Importance of Data Backups

This incident highlights a vital lesson for businesses of all sizes: the importance of maintaining regular and secure backups of all critical data and systems. Here’s why backups are essential:

  1. Mitigation of Data Loss: In the event of unauthorized deletions or other malicious activities, having up-to-date backups ensures that you can quickly restore lost data, minimizing downtime and operational disruption.
  2. Protection Against Internal Threats: Employees, especially those with high-level access, can pose a significant risk if they become disgruntled. Regular backups provide a safety net against potential sabotage.
  3. Business Continuity: Backups are a cornerstone of any business continuity plan. They ensure that your business can recover swiftly from IT disasters, whether caused by internal actors, cyberattacks, or natural calamities.
  4. Peace of Mind: Knowing that you have secure backups allows you to operate with confidence, knowing that you are prepared for unexpected events.
