Towards Automating Code-Reuse Attacks Using Synthesized Gadget Chains limiting its applicability to specific exploitation scenarios. Instead of using heuristics to find a gadget chain, we offload this task to an SMT solver. More specifically, we build a logical formula that encodes the CPU and memory state at the time when the attacker can divert execution flow to th

Peeler: Profiling Kernel-Level Events to Detect Ransomwarent the contextual behavior of applications by leveraging Bidirectional Encoder Representations from Transformers (BERT) pre-trained model. We evaluate Peeler on a large ransomware dataset including 67 ransomware families and demonstrate that it achieves a 99.5% F1-score.

We further analyzed 57,477 long-tail keywords promoted by blackhat SEO and found more than 157 SEO campaigns. Finally, we deployed . into the gateway of a campus network for ten months and detected 23,093 domains with malicious semantic confusion co

How to (Legally) Keep Secrets from Mobile Operatorsbad, secure channels are often subject to mass surveillance in the name of (inter)national security. Some protocols are constructed to allow easy data interception . Others are designed to preserve data privacy and are either subverted or prohibited to use without trapdoors..We introduce ., a primit

A Formal Security Analysis of Session Resumption Across Hostnamesing a previous session. In practice, this is often done via ., where the server provides a “self-encrypted” ticket containing the shared secret to its clients. A client may resume its session by sending the ticket to the server, which allows the server to retrieve the shared secret stored within the

Caught in the Web: DoS Vulnerabilities in Parsers for Structured Datacks with input that causes algorithms to execute in disproportionately large time and/or space. We generalise the characteristics of these vulnerabilities, and frame them in terms of three aspects, .: (1) the . of composite data structures formed by the internal representation of parsed data, (2) th

Characterizing GPU Overclocking Faults such as crypto-mining and neural-network training. It is common to overclock a GPU to gain performance, however this practice may introduce calculation faults. In our work, we lay the foundations to exploiting these faults, by characterizing their formation and structure. We find that temperature i
