Mobile forensics is the field that is required the most in today’s age. Mobile devices contain crucial data from general information, like age, to crucial data like location. Attacking this data can be very damaging to an individual; therefore, for safeguarding, mobile forensics and cybersecurity development are crucial.
What Are Mobile Forensics Investigations?
Mobile forensics can be denied as the forensic services that focus on recovering and analyzing data from mobile devices like smartphones, tabletsand wearable devices. The data includes call logs, text messages, emails, multimedia, location info, and even deleted data.
Mobile Forensic Investigation Process
The entire process of mobile forensic data can be divided into 6 phases:
- Seizure and preservation: In this phase, the mobile devices are collected and preserved in their original states to ensure that changes in the mobile devices do not occur. This step is crucial for safeguarding the original data present and preventing any tampering with data, like remote wiping, network interference, etc.
- Identification of the device: Once the data is collected and preserved, it’s important to identify the content of the device, like what type it is wearable, tablet, smartphone, etc., software authentication, whether it runs on android, IOS, or any other operating system and also the storage capacity of the device is determined. This information is crucial to understanding what data it could be holding inside.
- Collection of evidence: After determining the type of device and data it may be storing. The next phase is to collect evidence. Anything that can be related to an attack or looks suspicious or unusual will be collected as evidence. The data collected can be anything from multimedia like photos, videos, contacts, messages, and even deleted files and data.
- Analysis of data: The data collected in the previous phase is set for analysis in this next phase. The data collected is analyzed on the basis to find any unusual or suspicious activities in the data that can be used to find digital traces and evidence for the cyber attack.
- Documentation and preservation: the documentation phase is the phase where the data analyzed is stored, and it is also ensured that the original is untouched and in its original state. All the processes and techniques used are documented and stored and ensuring that they stand legal proceedings as well as maintain complete transparency.
- Presentation and correction: This is the final phase of the process where the data documented is filtered and corrected to make sure it is in credible and admissible form to present in the legal proceedings. Evidences are made in such a way that everyone can read through it, whether technical or non-technical.
Mobile Forensic Techniques
Manual Extraction: Manual extraction is the method where stakeholders browse through the mobile devices manually, browsing and recording visible data such as contacts, sms, and media. It is useful for a quick check but can’t uncover any hidden facts or truths, and is a time- taking process.
Logical Extraction: This method involves extracting active files such as SMS, emails, or contacts directly from the device’s operating system. It is a faster method, but it can miss hidden data or encrypted files.
Professional approach: This method follows hiring a professional team or company for mobile forensics, like Cybersics Forensics Services. This method can help conduct forensics fast and efficiently, and provide experienced help for forensics.
Physical Extraction: This method involves creating a bit-by-bit copy of the entire mobile storage. This can include data like app data, deleted files, hidden partitions, or encrypted data. This works by accessing the raw memory of the device.
Conclusion
Mobile forensics is a crucial method for forensic investigation, and it is extremely crucial in today’s era, where most of the digital data is present on mobile devices and is vulnerable to these attacks. It’s the role of cybersecurity and law enforcement to continue research and development of this.
