Abstract

The development of smartphone technology with the Android platform has made very rapid progress. Smartphones help and facilitate daily human work such as communicating, shopping, and financial transactions. However, because android is an open- source system, anyone can easily develop android applications that can be downloaded on the android app market. Including applications that have been inserted by malware by application developers, one of which is the Trojan downloader malware. The analysis was carried out by implementing the Trojan downloader malware infection in the health dictionary application using the reverse engineering method. Trojan downloader malware infection uses metasploit framework tools. The application will be infected with the payload created from the metasploit framework. This study will analyze the health dictionary application before and after being infected with the Trojan downloader malware using the reverse engineering method. The results of the analysis on the health dictionary application found that the difference in the size of the application was 10.17 MB, which previously was 10.05 MB. Of course, by changing the file size, the SHA256 hashing changes automatically. In the permissions section, it was found that there were only 9 permissions before being infected, but after being infected, we found 18 additional permissions, bringing the total to 27 permissions

Abstract

The XYZ office is a government agency covering various fields, ranging from government, economy, development, people's welfare, community life development and public service affairs. However, work activities in agencies were disrupted due to the COVID-19 pandemic which caused the government to impose a Large-Scale Social Restriction (PSBB) policy to suppress the spread of this virus, resulting in agency workers having to work from home. Therefore we need an appropriate means to be able to support these activities. One of them is making a technology design by implementing a VPN on a proxy router with the PPTP (Point to Point Tunnelling Protocol) method so that it can make it easier for employees to communicate without thinking about location. In addition, users can still remotely access the local network even though they are outside the office network. more secure. Based on the results of testing the network security at the XYZ Office before using the VPN Server, it proved that the wiretapping attackers could still obtain data in the form of website login information, proxy logins, or view data contents when exchanging data. Meanwhile, when the user connects to the VPN Server, the eavesdropper cannot see the contents of the data in it, then with the implementation of a VPN with the PPTP method, employees who are working from home can connect and communicate well with each other, with that work and information exchange will become more flexible and faster

Abstract

Yousee Indonesia menghadapi tantangan dalam mengukur lalu lintas kendaraan untuk visibilitas iklan. Menggunakan teknologi AI YOLOv8. Metode ini melibatkan pengumpulan data melalui Roboflow, anotasi data dengan kotak pembatas, dan pelatihan model dengan YOLOv8 nano. Dataset dibagi menjadi 70% pelatihan, 20% validasi, dan 10% pengujian. Hasil pelatihan menunjukkan bahwa performa model bervariasi antar kelas, dengan grafik Recall-Confidence menunjukkan penurunan nilai dan Precision-Confidence menunjukkan peningkatan nilai seiring peningkatan confidence. Meskipun rata-rata F1-score mencapai 84%, evaluasi menunjukkan kesulitan model dalam mendeteksi objek dan memprediksi label dengan tepat, khususnya untuk kelas ‘bus’ dan ‘truk’. Implementasi YOLOv8 memungkinkan pengumpulan data trafik yang akurat untuk analisis pola lalu lintas dan strategi iklan yang lebih efektif.

Abstract

Website security is one of the main concerns in the digital era, given the increasing potential for cyber threats. This research aims to improve website security by using the Vulnerability Assessment and Penetration Testing (VAPT) method that refers to the OWASP Top Ten standard. The applied method includes four main stages: information gathering, vulnerability scanning, exploitation, and reporting. The results showed that there were several successfully exploited vulnerabilities, such as Clickjacking, Improper HTTP to HTTPS Redirection, Directory Listing, and Sensitive Information Disclosure, which were classified based on the OWASP Top Ten. The severity of the vulnerabilities was analyzed using Common Vulnerabilities and Exposures (CVE), Common Weakness Enumeration (CWE), and Common Vulnerability Scoring System (CVSS). The analysis results show that some vulnerabilities have high severity after considering the factual conditions of the system. This research provides specific remediation recommendations to address these vulnerabilities, such as the implementation of security headers, deletion of sensitive configuration files, and dependency updates. With this approach, the research is expected to contribute to improving website security and provide effective mitigation guidelines.

Abstract

This research addresses the need for a water rescue device capable of autonomously moving towards a survival position while being remotely controlled. The main problem investigated is how to design an electric safety buoy that can move stably in currents and waves while being operated remotely using Internet of Things (IoT) technology. Data were collected through prototype testing under various load and control range conditions. The research method involves designing and implementing a control system based on the Arduino Uno microcontroller, with a Proportional-Integral-Derivative (PID) algorithm to maintain buoy stability, and an RF communication module for remote control up to 500 meters. The test results show that the buoy can achieve an average speed of 1.35 m/s at 100% throttle with an 80 kg load and maintain stability in various water conditions. The standard deviation of speed indicates minimal variation between tests, demonstrating good movement stability. This research contributes to the development of IoT-based safety devices, enhancing the effectiveness of water rescue operations. With the use of a PID algorithm, the buoy can automatically adjust direction and speed, making it more responsive to remote control commands and able to withstand dynamic water conditions.
