Peering into the Dark : A Dark Web Digital Forensic Investigation on Windows 11Kahlqvist, Johanna, Wilke, Frida January 2023 (has links)
The ability to access the Internet while remaining anonymous is a necessity in today's society. Whistleblowers need it to establish contact with journalists, and individuals living under repressive regimes need it to access essential resources. Anonymity also allows malicious actors to evade identification from law enforcement and share ill-intentioned resources. Therefore, digital forensics is an area that needs to stay up to date with these developments. We investigate what artefacts can be discovered by conducting acquisition and analysis of a Windows 11 computer that has used the Tor browser to browse the Dark Web. Our results identify a variety of artefacts acquired from Windows Registry, active memory, storage, and network traffic. Furthermore, we discuss how these can be used in a digital forensic investigation.

Dark Web Forensics : An Investigation of Tor and I2P Artifacts on Windows 11Abolghsemi, Seyedhesam, Chukwuneta, Chukwudalu January 2024 (has links)
With the rising use of the Internet by businesses and individuals for their regular activities and transactions, there has been increased attention to user privacy and data security on the web. While the adoption of dark web networks has ensured that users' privacy and anonymity concerns are being addressed, there has also been a consequential increase in illicit activities on the internet. The dark web remains a critical area for law enforcement investigations, providing a platform for criminal activities to thrive unchecked. This study evaluates the digital traces deposited by dark web browsers on the client side of user devices, providing a deep insight into the security features of Tor and I2P and outlining the potential areas where digital artifacts can be retrieved on a Windows 11 computer. By detailing the forensic acquisition process and subsequent artifact analysis, this research aims to enhance the capabilities of digital forensic examiners in tracking and prosecuting cybercriminals, thereby contributing to the broader field of digital forensics and cybersecurity.

Jämförelse av cache-tjänster: WSUS Och LanCache / Comparison of cache services: WSUS and LanCacheShammaa, Mohammad Hamdi, Aldrea, Sumaia January 2023 (has links)
Inom nätverkstekniken och datakommunikationen råder idag en tro på tekniken nätverkscache som kan spara data för att senare kunna hämta hem det snabbare. Tekniken har genom åren visat att den effektivt kan skicka den önskade data till sina klienter. Det finns flera cache-tjänster som använder tekniken för Windows-uppdateringar. Bland dessa finns Windows Server Update Services (WSUS) och LanCache. På uppdrag från företaget TNS Gaming AB jämförs dessa tjänster med varandra under examensarbetet. Nätverkscache är ett intressant forskningsområde för framtida kommunikationssystem och nätverk tack vare sina fördelar. Likaså är uppgiften om att jämföra cache-tjänsterna WSUS och LanCache intressant i och med det öppnar upp insikt om vilken tjänst är bättre för företaget eller andra intressenter. Både forskningsområdet och uppgiften är viktiga och intressanta när användare vill effektivisera användningen av internetanslutningen och bespara nätverksresurser. Därmed kan tekniken minska nedladdningstiden. Till det här arbetet besvaras frågor om vilken nätverksprestanda, resursanvändning och administrationstid respektive cache-tjänst har, och vilken cache-tjänst som lämpar sig bättre för företagets behov. I arbetet genomförs experiment, som omfattar tre huvudmättningar, och följs av en enfallstudie. Syftet med arbetet är att med hjälp av experimentets mätningar få en jämförelse mellan WSUS och LanCache. Resultatet av arbetet utgör sedan ett underlag för det framtida lösningsvalet. Resultaten består av två delar. Den första visar att båda cache-tjänsterna bidrar till kortare nedladdningstider. Den andra är att LanCache är bättre än WSUS när det gäller nätverksprestanda och resursanvändning, samt mindre administrationstid jämfört med WSUS. Givet resultat dras slutsatsen att LanCache är cache-tjänsten som är mest lämpad i det här fallet. / In the field of network technology and data communication, there is a current belief in the technology of network caching, which can store data to later retrieve it more quickly. Over the years, this technology has proven its ability to efficiently deliver the desired data to its clients. There are several caching services that utilize this technology for Windows updates, among them are Windows Server Update Services (WSUS) and LanCache. On behalf of the company TNS Gaming AB, these services are compared to each other in this thesis. Network caching is an interesting area of research for future communication systems and networks due to its benefits. Likewise, the task of comparing the cache services WSUS and LanCache is interesting as it provides insights into which service is better suited for the company or other stakeholders. Both the research area and the task are important and intriguing when users seek to streamline the use of their internet connection and conserve network resources. Thus, the technology can reduce download times. For this work, questions about the network performance, resource usage, and administration time of each cache service are answered, as well as which cache service that is better suited to the company's needs. The work involves conducting experiments, including three main measurements, followed by a single case study. The purpose of the work is to compare WSUS and LanCache using the measurements from the experiment. The outcome of the work then forms a basis for future solution choice. The results consist of two parts. The first shows that both cache services contribute to shorter download times. The second is that LanCache outperforms WSUS in terms of network performance and resource usage, and also requires less administration time than WSUS. Given the results, the conclusion is drawn that LanCache is the most suitable caching service in this case.
