MISHIMA: Multilateration of Internet Hosts Hidden Using Malicious Fast-Flux Agents (Short Paper)promised machines that act as proxies to hide the location of the host, commonly referred to as the “mothership,” to/from which they are proxying traffic. Fast-flux botnets pose a serious problem to botnet take-down efforts. The reason is that, while it is typically easy to identify and consequently

Code Pointer Masking: Hardening Applications against Code Injection Attacksanaries and protects against attacks that are not addressed by state-of-the-art countermeasures of similar performance. By enforcing the correct semantics of code pointers, we thwart attacks that modify code pointers to divert the application’s control flow. We have implemented a prototype of our so

Operating System Interface Obfuscation and the Revealing of Hidden Operationss—rely on knowledge of standard system call interfaces to reason about process execution behavior. In this work, we show how a rootkit can obfuscate a commodity kernel’s system call interfaces to degrade the effectiveness of these tools. Our attack, called ., allows user-level malware to invoke priv

An Assessment of Overt Malicious Activity Manifest in Residential Networkse” of the user populations (anti-virus and OS software updates) and potential risky behavior (accessing blacklisted URLs). We find that hygiene has little correlation with observed behavior, but risky behavior—which is quite prevalent—more than doubles the likelihood that a system will manifest security issues.

Timing Attacks on PIN Input in VoIP Networks (Short Paper)aper shows that a malicious intermediary can recover the inter-keystroke time delay for each PIN input even if the standard encryption mechanism has been applied. The inter-keystroke delay can leak information of what has been typed: Our experiments show that the average search space of a brute force attack on PIN can be reduced by around 80%.

Biting the Hand That Serves You: A Closer Look at Client-Side Flash Proxies for Cross-Domain Requestad to potential security problems. We comprehensively explore these problems and conduct a survey of five existing proxy implementation. Furthermore, we propose techniques to avoid the identified security pitfalls and to overcome the untrustworthy interface between the two technologies.
