Computer and Cell Phone Forensics Investigation

Forensics Investigation


In this day and age, a ton can be found by directing quick security research, whether that investigation relates to PCs or potentially cybercrime.

Forensics Investigation

PCs or potentially cybercrime issues can be viewed as both common and criminal acts. They are based upon the current realities of the case. An expert and professional private investigator can make quick work of the issue before it goes into an unsafe mode.

What Should You Know About Computer and Cell Phone Forensics Investigation?

In view of the confounded idea of this sort of examination, an experienced OKC Private Investigator may expect you to assist with setting up the case by setting up your PC or PDA for this kind of research. Before you contact the Private Investigator, make sure to record the make and model of your PC or mobile phone.

You may likewise need to clear any passwords if you know them. The data are expected to make quick work of the current issue. However, you need to have confidence that a decent specialist can discover the data required, whether you can’t play out these obligations all alone.

Role and Restrictions of Computer Forensics Investigation:

Any violations that are carried out using PCs, PDAs, or the web is viewed as cyber-crimes. Many cybercrime companies use things like spyware, malware, infections, and hacking to make everyone’s data secure and safe. Data criminals or hackers can discover and utilize the person’s data without your authorization, which is the reason you keep yourself secured.

Despite the fact that PC criminology and cybercrime cases frequently assemble into a similar class, a reliable and professional Private Investigator can differentiate. Also, a certified specialist can look at the proof found and afterward contrast the discoveries and the tradition that must be adhered to. Some experienced data agents regularly use various techniques to accumulate and investigate PC and phone information for the benefit of their client(s).

Explore Method for Managing a Computer Forensics Investigation:

Information collected from electronic devices can be used as evidence effectively. The information may include images, emails, text messages, computer documents, instant texting, transaction history, and browsing history. Such as “Cloud” is an online-based backup system in electronic devices, which provides access to images, documents, and text messages on a particular mobile device to investigators. It can store approximately 1000 to 15,000 recent records of sent and received text messages and image history.

Additionally, nowadays, many mobile devices store your device location where it was present and where it traveled. Investigators can access about 200 last mobile location information. They can get similar location information for cars by using satellite radios and satellite navigation systems. Media and files on our social media accounts like Facebook, Instagram also collect your location and data information.

Photos in mobile phones devices with a Global Positioning System (GPS) also contain the file information that shows the exact location where the photo was taken. Investigators can access mobile device history and its owner information by getting access to the subpoena of a mobile device.

After collecting the digital evidence from electronic devices, they are sent to laboratories, where expert investigators analyze and restore data by taking the following steps:

1. Collecting Evidence:

Evidence data collection from the crime scene like DNA, fingerprints, and other important details can be contaminated in the collection process. The same can happen with digital evidence. Some precautions should be followed by the data analyst to prevent this situation. Before collecting or analyzing digital data, a work copy or image of the original file is created. The image or work copy should be stored on other devices or other media platforms when collecting evidence from the suspect device.

Data analysts must use clean or virus-free storage devices to store data to prevent the distortion or contamination of data from the source. For example, if an analyst uses a CD drive to store data that already has some information stored, that information can be analyzed with the original information on the suspect device.

2. Explore Storage Devices:

Many storage devices like thumb drives, USB, or data storage cards are reusable. It is not enough to just clean all data and put it in storage devices. The final storage device must be new, or if it is reused, then it should be “cleaned” in the laboratory under expert direction. This will remove all available and not available data from that storage device.

Wireless devices like mobile phones and other devices, if possible, should be examined under an isolated chamber. It will prevent them from connecting to any other network and help to keep the evidence in original condition.

The evidence bag should be opened in the isolation chamber, and the device can be used to collect mobile phone information, SIM Cards, FFC information (Federal Communication Commission), etc. The suspect device can be connected to data analyzing software inside isolation chambers. If an investigation agency does not have isolation chambers, the analyst can put the device in an evidence bag and enable the airplane mode to prevent any connectivity.

3. Making an Editable Data:

Data, files, and media in electronic devices are easy to delete, edit or manipulate. To prevent this situation, the analyst will install blocking software on the working data copy. It can help them to only examine the data and media files, but nothing can be edited or removed.

After creating the working copy of the device and data, the analyst will investigate the model and manufacturing of the device. This will help them to select the best-matched extraction software according to the device to examine the data and access its information content.

After exploiting the data from the device, the suspect device is sent back to the evidence collecting team. The device can contain fingerprints, DNA samples, and other important evidence that can help in the investigation. Once the data is extracted, the data analysts can work without the device.

4. Use of Investigation Software:

It is the last stage of data investigation. At this stage, the data investigators use different software to view and investigate data and its contents. This software allows data investigators to access all the files on the drive; they can also view and access the media and files that are hidden, or even they can restore removed and deleted files. These deleted files can be recovered or accessed as long as they are not overwritten by some new files or data in the device. An analyst can also use partially deleted files to extract data.

Final Verdict:

Files and documents are not the only forms of evidence that data investigators can collect from electronic devices. The data investigators have to work on other data sources far off from hardware, like internet history, chat rooms, instant messaging, website browsing history, etc. The data analyst joins pieces of information to get a clear picture of activities from different sources like internet IP addresses, email information, messaging timing stamps, and other data collected from their devices.

Frequently Asked Questions (FAQs):

1. How does mobile phone crime investigation work?

Cell phone crime investigation is a part of computerized legal sciences. In this process, the experts identify the recuperation of advanced proof or information from a cell phone under forensically strong conditions. Cell phones can be utilized to save a few sorts of people data like contacts, photographs, schedules and notes, SMS, and MMS messages.

2. What are the six periods of the Computer Forensics Investigation?

There are the following six periods of Computer Forensics Investigation. It includes Requirement Analysis, Data Retrieval, Data Reliability, Crime Evidence Review, Evidence Representation, Repository of Data Explanation, and the last Characteristics of Each stage. Some experts also conduct the Requirement Analysis to analyze the outcomes.
