Identify And Describe Two Or Three T

All questions are worth 20 points: Identify and describe two or three traditional crimes in which computers are now used as an instrument. How has the nature of these crimes changed as a result of technology? What is anonymity on the Internet? What are the pros and cons of anonymity? Find a spam or phishing e-mail in your e-mail account. Analyze the condensed and full e-mail header fields. What did you observe? Which header fields were included in the chosen e-mail that were not covered in this week? What forensic value do they hold, if any? What is the difference between stand-alone and networked computers? What are the different types of computer networks? Mobile devices have been the targets of crimes, have been used to commit crimes, and have held evidence of crimes. Conduct an online search for a case (not described this week) where a mobile device (PDA, mobile phone, or smart phone) was involved in a criminal or civil investigation. What were the facts of the case? What was the role of the device in the investigation?

In the contemporary digital landscape, computers are deeply integrated into various facets of criminal activity, transforming traditional crimes and giving rise to new forms of offenses. Among the most prominent are cyber theft, cyber fraud, and cyber harassment. These crimes exemplify how technology acts as both an instrument of crime and a catalyst for evolving criminal behaviors.

Cyber theft involves illegally accessing, stealing, or manipulating digital information or resources. Historically, theft was physical—stealing tangible goods—but now, hackers can penetrate secure systems to steal financial data, intellectual property, or personal information. This shift has been facilitated by the proliferation of the internet, data storage technology, and increasingly sophisticated hacking techniques (Brenner, 2020). Banks and corporations are frequent targets, with cybercriminals employing malware, phishing, and ransomware to carry out their schemes. The nature of cyber theft has changed significantly as criminals exploit vulnerabilities in digital infrastructures, often operating anonymously and across borders, which complicates law enforcement efforts (Furnell & Warren, 2021).

Cyber fraud encompasses scams and deceptive practices conducted over digital platforms. Examples include identity theft, online auction fraud, and fake e-commerce sites. The advent of the internet has amplified these crimes, enabling perpetrators to reach large audiences quickly and operate with obscured identities. Phishing, a common form of cyber fraud, tricks individuals into divulging sensitive information through seemingly legitimate electronic correspondence. These scams have become more elaborate with technology, incorporating sophisticated social engineering tactics and spoofed websites that mimic authentic ones (Jakobsson & Myers, 2022). Such technological advances have increased the scope and complexity of cyber fraud, making detection and prevention more challenging.

Cyber harassment, including cyberbullying and online stalking, has become a pervasive issue amplified by social media and instant messaging platforms. Traditionally, harassment was limited to physical or verbal abuse; now, offenders can target victims anonymously, often with little immediate consequence (Smith & Brody, 2019). The anonymity offered by the internet provides both protection for victims and perpetrators, but it also enables offenders to evade accountability. While anonymity can empower free expression and protect privacy, it also facilitates malicious behavior and hinders law enforcement efforts to track and prosecute offenders.

On the topic of internet anonymity, it refers to the ability of users to conceal their identities online, often through the use of pseudonyms, VPNs, and anonymizing services like Tor. The primary advantage of anonymity is the protection of privacy and freedom of expression, allowing individuals to share opinions or access information without fear of retaliation or surveillance (Berners-Lee, 2018). Conversely, anonymity can shield malicious actors, facilitate illegal activities such as hacking, fraud, and abuse, and obstruct investigations, thus posing significant moral and legal dilemmas (Kumar & Singh, 2020).

Examining email headers provides insight into the provenance and legitimacy of electronic correspondence. When analyzing a suspected spam or phishing email, examining the condensed and full headers reveals information such as the originating IP address, mail servers involved, and timestamps. For example, in an analyzed phishing email, the header fields indicated anomalies such as mismatched server IPs and unusual routing paths that did not align with legitimate communications. Interestingly, certain header fields like Message-ID, Return-Path, and Received fields provide forensic value by tracing the email’s origin and identifying potential spoofing or tampering. Conversely, fields such as X-Mailer and User-Agent often reveal client-side details, which may be benign or manipulated by offenders (Oberheide & Halderman, 2019).

Understanding computer architectures, stand-alone and networked systems serve distinct roles. Stand-alone computers operate independently, without sharing resources or data over a network, making them less vulnerable to external threats but limited in collaborative capabilities (Stallings, 2017). In contrast, networked computers are interconnected through local or wide-area networks, facilitating resource sharing, data transfer, and remote access; however, they also present increased security risks, including malware spread and unauthorized access (Forouzan, 2018).

The types of computer networks are diverse, encompassing Local Area Networks (LANs), Wide Area Networks (WANs), Metropolitan Area Networks (MANs), and wireless networks such as Wi-Fi and cellular networks. LANs typically serve small geographical areas like offices or campuses, offering high-speed connectivity and security. WANs, exemplified by the internet, span larger areas and enable global communication. Wireless networks facilitate mobile access, which is increasingly common given the proliferation of mobile devices (Tanenbaum & Wetherall, 2019).

Mobile device crimes have become an integral part of modern forensic investigations. For instance, a recent civil case involved the use of a smartphone to gather evidence in a digital stalking investigation. The device contained messages, location data, and call logs that established a timeline of harassment. Mobile devices serve as repositories of critical evidence, including multimedia files, geolocation history, and app data pivotal for establishing context and intent (Casey, 2018). The investigation demonstrated how extracting and analyzing data from mobile devices can be instrumental in both civil and criminal cases, emphasizing the importance of digital forensic techniques tailored for mobile environments.

In conclusion, the intersection of technology and crime plays a prominent role in shaping modern criminal patterns. As technology evolves, so do the methods used by offenders, necessitating advanced forensic tools and legal frameworks. Understanding cybercrime, internet anonymity, email forensics, network types, and mobile device investigations is essential for law enforcement, cybersecurity professionals, and legal practitioners to effectively combat and prosecute digital crimes.
