Testing the malicious USB anecdote
In today’s computer security climate, attacks against computers are becoming increasingly sophisticated and cheaper to execute. In this thesis, we present the results of a study conducted on the University of Illinois campus to determine the effectiveness of dropping 297 “infected” USB flash drives …

Analysis avoidance techniques of malicious software
… and heuristics to detect the presence of malicious software (malware). The generation of signatures and determination of heuristics is dependent upon an AV analyst having successfully determined the nature of the malware, not only for recognition purposes, but also for the determination of …

Protecting agents against malicious host attacks
… but research in protecting the agent from malicious host attack is evolving. This research proposes two approaches to protecting an agent from being attacked by a malicious host. The first approach consists of an obfuscation algorithm that is able to protect the confidentiality of an agent …

Exploitation from Malicious PCI Express Peripherals
… systems are still vulnerable to attacks from malicious peripherals delivered over the PCI Express (PCIe) protocol. Malicious peripherals can be plugged directly into internal PCIe slots, or connected via an external Thunderbolt connection. To prove this thesis, we designed and built a new PCIe …

Investigating representations of obfuscated malicious PowerShell
… methods rely on detecting signatures of known malicious scripts which can be easily broken with simple obfuscations. This work seeks to find a more abstract representation of script functionality using Abstract Syntax Trees so that an unseen obfuscated script can be detected if a related script …

A Lexical Approach for Classifying Malicious URLs
… is a need for intelligent systems to identify malicious web pages. It has been shown that URL anal- ysis is an e\u21b5ective tool for detecting phishing, malware, and other attacks. Previous studies have performed URL classification using a combination of lexical features, network tra c, …

Managing malicious transactions in mobile database systems
… to misuse their privileges for fulfilling their malicious intent. It is a fact that most external security breaches succeed mainly with the help of insiders. An example for an insider is the Enron scandal of 2001 which led to bankruptcy of Enron Corporation. The firm was widely regarded as one of …

Parsimonious Service Replication for Tolerating Malicious Attacks in Asynchronous Environments
We consider the subject of tolerance of the most severe kind of faults, namely Byzantine faults, through state machine replication in asynchronous environments such as the Internet. In Byzantine-fault-tolerant (BFT) state machine replication, state consistency among the replicas of a service is …
