• Abstract: Presently, Bangladesh is expending substantial efforts to digitize its national infrastructure, with a significant emphasis on achieving this goal through mobile applications that facilitate online payments and banking system advancements. Despite the lack of knowledge about the security level of these systems, they are currently in frequent use without much consideration. To observe whether they follow the minimum global set standards, we choose to conduct static and dynamic analysis of the applications using available open-source analyzers and open-source tools. This allows us to attempt to extract sensitive information, if possible, and determine whether the applications adhere to the standards of MASVS set by OWASP. We show how we analyzed 17 .apks and a SDK using open source scanner and discover security flaws to the applications, such as weaknesses related to data storage, vulnerable cryptographic elements, insecure network communications, and unsafe utilization of WebViews, detected by the scanner. These outputs demonstrate the need for extensive manual analysis of the application through source code review and dynamic analysis. We further implement reverse engineering and dynamic approach to verify the outputs and expose some applications do not comply with the standard method of network communication. Moreover, we attempt to verify the rest of the potential vulnerabilities in the next phase of our ongoing investigation.

  We present PathSentinel, which overcomes the limitations of previous techniques by combining static program analysis and access control policy analysis. By unifying program and access control policy analysis, PathSentinel identifies attack surfaces accurately and prunes many impractical attacks. To streamline vulnerability validation, PathSentinel leverages large language models (LLMs) to generate targeted exploit code.
