Due to the extensive use of mobile devices and cloud computing, digital forensics investigations have grown increasingly complex. The main challenges that forensic investigators in the fields of mobile and cloud forensics encounter are discussed in this study. The proliferation of various devices, operating systems, and applications creates challenges for data capture, extraction, and interpretation in the context of mobile forensics. Additionally, the process is made more difficult by the usage of privacy and encryption tools. The extraction and analysis of digital evidence from distributed, frequently encrypted cloud systems is the focus of cloud forensics, on the other hand. Significant barriers include questions of jurisdiction, data ownership, and secure access. This presentation examines the evolving field of digital forensics with a particular emphasis on the complex problems that mobile and cloud technologies present.
