Week-14 Research Assignment

By

Nagendra Babu Chinnam

Digital forensics is the process of investigating by accumulating evidence from digital equipment like computers, networks, cloud, hard drive, and any endpoint

system connected to the technological infrastructure. Digital forensics involves retrieving evidence by preserving or recording the digital devices' state, analyzing them, and reporting the information recovered. In instances of cyber-attack crimes, a digital forensics examiner analyzes the digital attack to retrieve evidence to help track the attackers. In today’s world, with more than 95% of people having cellphones, the data existence is staggering. The mobile phones involved in the investiga- tion and devices like laptops, desktops, smart watches, and all other devices that fall under the internet are capable of data exchange. Data forensics has been

particularly stressed by the emergence of higher sophisticated devices (Kävrestad, 2018). Digital forensic methods are used to solve the crime by law enforcers

and investigators every day. For example, there was this case in the United Kingdom back in 2009 of a particular guy, Krenar Lusha, who was an illegal immigrant to the UK. He was arrested based on his internet search engine pattern. He was found guilty due to the help of digital forensics. Once the computer forensics

experts investigated his laptop, they discovered that he had downloaded a manual of 4300GM that contained information to make search belts and explosives. This opened up the case, giving them the warrant for further investigation to search his house, where they found 71.8liters of petrol, potassium nitrate, and a live shotgun cartridge. Digital forensics also showed other evidence that he had used his laptop to message people via MSN, where he described himself as a terrorist and a

sniper. In the messages, he portrayed himself as someone who hated Jewish and American people and wanted to see them dead. All this information was re-

trieved from his laptop using digital forensics and used as digital evidence in court (Roussev, 2016). Several criminal cases have used digital evidence to uncover hid- den scams. In most criminal cases, whenever there is not enough evidence gathered from all the sources acquired, digital forensics will often provide adequate evid- ence to convict the person. Most of these digital devices that we use can store 99%of the information that we feed them, and in case of a criminal investigation, they come in handy. Digital forensics is an effective method to solve crimes commonly used today by investigators (Husain & Khan, 2019).
