A Lightweight Design Approach to Detect Malicious Injections in Government Websites: Combating Hidden Online Gambling Pages

The increasing case of online gambling activities in Indonesia requires the government, particularly through the Ministry of Communication and Digital (Komdigi), to pay special attention to addressing this issue. Komdigi has actively conducted outreach programs about the dangers of online gambling from various aspects of life. Additionally, thousands of websites suspected of hosting online gambling activities have been blocked. However, many security vulnerabilities remain in government-owned web applications, making them vulnerable to hacker attacks, such as illegal hidden online gambling page injection into these websites. Therefore, this study developed a method to prevent hackers from performing injections or upload unwanted hidden online gambling page using a Bash script that leverages the lnotify(); function feature available in Linux operating systems. This Bash script is designed to be lightweight, minimizing the use of resources such as CPU and server memory. This approach enables quick detection and send notification to suspicious activities without disrupting the server's primary performance, making it a suitable solution for implementation in government infrastructures that often face resource constraints.
