They were then approached for the job, the money, to be paid in cryptocurrencies, with the threat of the sale of the bills and other vital records associated with it, such as online credit card information. Less-organized hackers have access to that money from the victim’s bank account or wallet. Hackers are taking the SIM connections in one of three ways. The most common one is called “the replacement of the SIM card with the call. In this case, they are the first to gather information about the target audience of your last name, first name, physical address, telephone number, date of birth, a password, with the help of a phishing attack, or, the leaks database is located on the dark web (the part of the Network that is not tracked by the search engines).

The research methodology
The research method used in research is Qualitative, and through quantitative methods used to achieve the objectives of the work. The qualitative analysis role is the most crucial feature of qualitative research because Ii has played a key role in principle, being suitable for small samples, and the results have been tremendous and sensitive. The main advantage is one of the major differences in quantitative research because it is a description and an analysis of the topic of an individual study, without any limitation of scope study and nature of the participants’ responses.
The research paper survey was conducted with the help of telephonic interviews as students and faculty members are in their hometowns due to Pandemic. The sample size is 100 (50 males+50 female) . It was a snowball sampling as the students and faculty members who are composing ideology regarding the security issue of SIM hijacking all around the globe.
We used qualitative methods to gather data about out lookers who may experience insecurity in SIM hijacking. These methods included surveys with various questions that assessed whether people ever felt insecurity or caught in scam, insecure about their personal data, and/or distracted from their regular work due to hacking/ hijacking. The surveys were distributed to 100 members (18-55years old) through google forms and linked in polls, 50 of whom were recipients of title accused in hijacking or fraud calls. The remaining 50 were a control group of people who were not identified as social hacking disadvantaged.
Through the analysis we have set up the configurations in the following three categories:
safe, dangerous, and doubly difficult.
In a double-hazardous structure specifying that the replacement of the SIM card is not sufficient to compromise the security of your account, the configuration makes use of SMS-MFA-and-SMS-password-recovery. A dangerous design can only be broken if the attacker knows the password to the account; these are configurations that provide SMS-based authentication, but it does not allow you to enter the password via an SMS message.
