Hardware-Based Methods for Memory Acquisition: Analysis and Improvements
No full textSome server hosters facilitate cyber crime either intentionally (so called “bulletproof hosters”) or unintentionally (“bad hosters”). When dealing with uncooperative hosters during forensic investigations, it may sometimes be necessary to collect data or information on the servers without help from the owner of the server. Data within the RAM might prove insightful in, for example, determining active processes or reveal crypto graphically interesting information like encryption keys. The thesis explains key concepts within memory organization and the PCIe standard.Afterwards, it discusses several techniques for RAM acquisition and categorizes and evaluates them using a model-based approach. The thesis then dives deeper into DMA-based memory acquisition using PCIe and proposes several improvements to current DMA attacks in order to create a better memory acquisition technique. A novel memory acquisition technique is created by hot-plugging aPCIe device and skipping over the regular enumeration procedure. This techniqueal lows the memory acquisition to be executed without a reboot and provides a stealth approach to accessing the memory. Computer Engineerin
Denial of service using the example of Croatian hosters
No full textThis graduation thesis is oriented towards Denial of Service attacks, more specifically on web hosting companies. The purpose of this thesis is to make a deep analysis of the Croatian market, as nowadays businesses are oriented almost exclusively on the Internet. This thesis includes tests on real production environments, for which this author has exclusive approvals. Focus is primarily on Layer 7 and Layer 4 attacks. Several methods were used for this thesis, and the results are presented in the form of penetration tests, mentioned in the work itself

Short circuits of reality: reproducibility, simulation and technical images in Villiers de l'Isle Adam's "L'eve future," Rainer Werner Fassbinder's "Welt am Draht," and Michael Haneke's "Caché"
No full textMy dissertation “Short Circuits of Reality: Reproducibility, Simulation and Technical Images in Villiers de l’Isle Adam’s L’Eve Future (1887), Rainer Werner Fassbinder’s Welt am Draht,(1973) and Michael Haneke’s Caché (2005)” examines the reciprocal relationship between the evolution of visual media technologies and sensory perception. Reading the 20th century as an era of simulation shows that there has been a historical connection between tendencies of simulation and the invention of audiovisual media technologies that enabled the increasingly “photo-realistic” reproduction of our material reality. This interplay and feedback loop between reality and literary imagination created the first female android in literature as a new media technological dawn was on the horizon in the outgoing 19th century. The rise of the mechanical machines and media technological apparatuses inaugurated the industrial age and the beginning of modernity.
Preceding the analyses of Villier’s de L’Isle Adam’s L’Eve Future (1887), Rainer Werner Fassbinder’s Welt am Draht (1973), and Michael Haneke’s Caché (2005), I offer a theoretical and terminological foundation. It is based on three thinkers on the impact of media technologies on perception from the now considered “classic era of media theory.” Walter Benjamin’s thoughts on reproducibility and the replacement of original sources by ubiquitous copies are followed by Jean Baudrillard’s concept of simulacra and simulation. Here, the distinction between original and copy gradually becomes obsolete in the state of simulation and hyperreality. Vilém Flusser’s theory of technical images and technical imagination stands in contrast to Baudrillard’s, as he counters the deceptive quality of the simulacra by approaching “technical images” (images created by apparatuses) as signifiers that project meaning outwards instead of inwards.
The following second chapter is concerned with the notion of unstable sources and the depiction of phonographic, photographic and cinematic media technologies as narrative devices in Villiers de l’Isle-Adam’s novel l’Eve Future from 1887. I argue that the simulation of these media technologies in the narrative enables the destabilization of original sources and replaces them with simulacra that ultimately cannot be sustained.
The third chapter analyzes the “aesthetics of simulation” implemented in Rainer Werner Fassbinder’s World on a Wire (1973). In a combination of philosophical and existential reflections on the nature of reality, the film calls the perception of reality radically into question while employing a simulative aesthetic that includes the spectator in its cinematic framework.
The fourth and final chapter reads the “image as projectile” in Michael Haneke’s Caché (2005). It includes not just the spectator in its visual framework, but also what is purposely left outside of the film-frame. By combining Benjamin’s notion of shock and Flusser’s concept of projection in relation to technical images, I intend to show that Haneke’s moral impetus is related to the (mis)perception of technical—and in this case, digital—images, which have a simultaneous abstract and concrete violent quality. The question that Haneke transfers to the viewer is then, to what extent are we responsible for the violent images we are willingly exposed to on a daily basis?Ph.D.Includes bibliographical referencesby Sascha Hoster
