Why is Indonesia an Attractive Target?
Before reviewing domestic case studies, it is important to understand the background behind why Indonesia has become a target for ransomware. Rapidly developing digital infrastructure without corresponding security enhancements has created an increasingly open space for attacks. These factors provide an initial picture of the conditions that enable attackers to exploit vulnerabilities.
The high adoption of digital services, the use of cloud-based applications, and varying levels of security preparedness make many organizations vulnerable to attacks. It is these gaps that attackers exploit to penetrate systems and launch attacks.
Attack Patterns and Exploitation Opportunities
To understand how incidents can occur, we need to look at the attack patterns most often used by perpetrators. These patterns reflect weaknesses that organizations need to strengthen, while also revealing common entry points used to penetrate internal systems.
Ransomware attacks generally exploit phishing, outdated systems, credential compromise, and misconfiguration. Once a door is open, attackers can spread quickly and paralyze the system in a short time.

Examples of Ransomware Cases in Indonesia
Before discussing defense strategies, looking at a number of real incidents will provide a clearer picture of the scale of the threat and its impact. Each case shows how different weaknesses can lead to huge losses.
1. Ransomware on Digital Public Services
Attacks on public services show how crucial electronic administration systems are in people's lives. When the main server was encrypted, all verification, administration, and population data access services came to a complete halt.
This indicates that the infrastructure depended on a central point that did not have adequate redundancy, so when the control center fell, all operations were paralyzed.
Public services require a more distributed architecture, isolated backups, and rapid recovery mechanisms. In addition, the lack of attack monitoring and early detection allows malware to run freely until it reaches the main server.
Public service organizations need to strengthen their real-time monitoring and Zero Trust-based access verification systems so that attacks can be stopped before they have a widespread impact.
2. Ransomware in Digital Education Institutions
Academic environments store large amounts of data, but often rely on outdated applications and systems that are rarely updated. When perpetrators exploited vulnerabilities in unpatched remote access, they successfully penetrated the system and encrypted grade archives, student data, and internal documents.
This operational disruption lasted a long time because the institution did not have a ready-to-use recovery mechanism.
This case illustrates the importance of patch management discipline in the education sector.
Educational institutions need to strengthen their update policies, migrate old applications, and prepare a Disaster Recovery Plan that can be implemented without relying on manual processes.
3. Ransomware in Digital Transportation Companies
In the app-based transportation industry, every minute of downtime has major consequences. When transaction and booking servers are encrypted, the app cannot process requests, the control center loses visibility of the fleet, and customers are immediately affected.
This attack highlights the need for high-availability architecture, isolation of critical servers, and recovery automation.
In addition, companies need to tighten security for APIs, endpoints, and network traffic.
Regular resilience testing through penetration testing and incident simulation can also help teams identify weaknesses before attackers exploit them.
4. Attacks on Energy and Infrastructure Companies
In the energy sector, cyberattacks not only disrupt data but also threaten vital public services. In this case, the perpetrators only needed one phishing email to enter the internal network and lock down the digital distribution system.
This case confirms that human factors remain the most common entry point for ransomware.
Strong network segmentation and the implementation of least privilege access are essential in critical sectors.
5. Ransomware in the Healthcare Industry and Hospitals
Attacks on hospitals provide a clear example of how digital threats can directly impact human safety. When electronic medical records, doctor schedules, and billing systems are locked, medical services are disrupted.
The healthcare sector requires layered protection for critical systems, ranging from the separation of medical record servers, the securing of administrative applications, to the implementation of EDR and XDR to quickly detect threats, including mass encryption attempts due to ransomware attacks.
EDR (Endpoint Detection and Response) focuses on protecting devices and servers by monitoring activity in real-time, detecting suspicious behavior, and enabling rapid responses such as system isolation or termination of malicious processes. This technology is important because endpoints are often the initial point of entry for attacks.
Meanwhile, XDR (Extended Detection and Response) expands the capabilities of EDR by correlating data from various security layers, such as endpoints, networks, cloud, email, and user identities. This integrated approach provides comprehensive visibility into complex attack patterns and accelerates response before disruptions spread to vital healthcare systems.

Strategies for Dealing with Ransomware Threats
The following are some strategies that can be used to prepare for and prevent future ransomware attacks.
Isolated and Multi-Layer Backups
Backups are a key component in maintaining access to critical data. Isolated backups prevent chain encryption and ensure that data can be recovered without interruption.
Zero Trust Framework
Modern security models require strict verification of every activity. Zero Trust works on the principle of “never trust, always verify” across all access paths.
System Updates and Hardening
Many attacks occur because systems are not consistently updated. Regular patches and proper security configurations help close critical gaps.
SIEM & 24/7 Monitoring
Early detection provides valuable time to prevent attack escalation. With SIEM, network activity can be thoroughly analyzed to detect anomalies as early as possible.
Automatic Disaster Recovery
Disaster Recovery helps maintain business continuity without having to wait for the attack to be stopped by the perpetrator.
