Abstract

WhatsAppis one of the most widely used messaging applications because of its ease and speed in exchanging information, including image files. However, behind this convenience, there is a hidden threat in the form of malware insertion through image files. Cybercriminals often use steganography techniques to embed malicious code in images without changing their visual appearance. When the image is downloaded and opened, malware can be activated and attack the user's device. This article discusses the potential dangers of images on WhatsApp, virusinsertion techniques, and protection strategies that can be carried out. The methods used are literature studies and analysis of real incidents, such as the case of the spread of Pegasus spyware. The findings show that low user awareness, automatic download habits, and the use of unofficial applications increase the risk. As a protective measure, users are advised to disable the automatic download feature, routinely update applications, use antivirus, and be careful with files from unknown sources. This article also emphasizes the importance of increasing digital security literacy and innovation in the development of automatic detection features on communication platforms. With a better understanding, users can take preventive steps against cyber attacks that are disguised through visual media.

Abstract

The adoption of web-based cashier systems has become a common choice among small and medium-sized enterprises due to their ability to streamline transaction processes and simplify sales data management. Nevertheless, ensuring the quality of such software requires a structured testing and validation approach. This study focuses on applying the ISO/IEC 29119 international standard as a framework for testing a web-based cashier system. The research stages include test planning, test case design, test execution, and result evaluation in accordance with the standard. Findings indicate that the system meets functional, reliability, and usability requirements aligned with operational needs. Validation was conducted by comparing test outcomes with system specifications and business requirements, leading to the conclusion that the tested web-based cashier system is suitable for implementation. The application of ISO/IEC 29119 provides a systematic and consistent methodology for software testing, thereby enhancing confidence in the quality of the developed system.
