Due to the ubiquity of mobile devices for digital identity verification, SIM swapping has emerged as an unintended high-stakes vector for cybercrimes. With the advancement of telecommunications technology from GSM to 5G, reliance on the Subscriber Identity Module (SIM) for two-factor authentication (2FA) has become a critical vulnerability. In this paper, fraudsters employ a variety of techniques, ranging from social engineering to technological exploitation, across both traditional and contemporary network infrastructures. We investigate identity takeover methods that circumvent traditional security mechanisms and cause significant financial and personal losses. In addition, this study assesses telecom infrastructure weaknesses where unique vulnerabilities of GSM, LTE, and UMTS interworking exist, and covers new attacks, including AdaptOver. Eventually, we propose a model for forensic countermeasures and mitigation by focusing on location-based verification, devicespecific authentication binding, and increased ceremony modelling to protect subscriber identities.

Extracting nucleic acids for identification of suspects in the field of forensic science is still an arduous assignment and requires less intensive and labour free protocols. Liver tissue of mammals is known to contain high density of nuclei which leads to extraction of high amount of genetic material. Therefore, DNA extraction has been performed using newly developed lysis method with conventional method as well as the nanocomposites were brought in use to check the adsorption and elution capabilities. The developed magnetic nanocomposites CFO@ZnO were synthesized using solution combustion method and co-precipitation method and characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). The newly developed CFO@ZnO nanocomposites show exceptional quality of DNA extraction by the revamped approach of lysing the cells as compared to the traditional method of cell lysis. This cutting-edge method is cost efficient as well as less time consuming with superior performance and thus proves to be an updated strategy of cell lysis.
