The first line of defence for malware authors is often to bypass static analysis, a relatively straightforward task using readily available tools such as packers and cryptors. To address this shortcoming, defenders send potential malware samples for execution in a sandbox environment. While sandboxing can provide valuable insights into the behaviour of software on an information system, advanced techniques like anti-virtualisation and hooking evasion allow malware to escape detection. The primary objective of this work is to complement sandbox execution with symbolic execution frameworks to detect new malware strains efficiently. Symbolic execution offers a distinct advantage over sandboxing by achieving greater coverage of all possible execution traces, as it can explore every potential execution path, regardless of the evasion methods employed by the malware authors. By carefully selecting the samples to be analysed, we can significantly reduce the workload while extracting essential dynamic features in a fraction of the time and with far fewer computational resources compared to sandboxing. To this end, we leverage machine learning in an automated pipeline, enabling the accurate detection of sophisticated malware using a real-world dataset. Our approach yields average F1 scores of 0.93 for the benign class and 0.99 for the malware class in a binary classification setup, surpassing the detection rates reported in the literature. Additionally, our method outperforms a commercial malware sandbox when applied to the same dataset, further highlighting the efficacy of the proposed method.</div></div>","PeriodicalId":51004,"journal":{"name":"Computers & Security","volume":"149 ","pages":"Article 104193"},"PeriodicalIF":4.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with the advancement of industrialization and informatization, ICS face increasing security threats, particularly from cyber-attacks. As a core technology for ICS security, intrusion detection has garnered significant attention in recent years. Traditional intrusion detection methods typically rely on models constructed from network event logs, but these methods have notable limitations in capturing the spatiotemporal correlations among multiple variables (sensors/actuators) and the periodicity of data within the system. To address these challenges, this paper proposes an ICS intrusion detection method, PdGAT-ID, which integrates periodicity extraction with spatiotemporal graph attention networks. This method aggregates multi-scale periodic information from time series and utilizes spatiotemporal graph attention networks to capture the system's spatiotemporal features, thereby enhancing the accuracy and reliability of detection. Experimental results on three publicly available datasets, SWaT, WADI, and Gas Pipeline Dataset, demonstrate that PdGAT-ID performs exceptionally well in detecting abnormal behaviors and intrusion events.

These models, particularly those that utilize model-extracted features, significantly enhance classification performance while minimizing the need for extensive expert knowledge from developers. However, a critical challenge lies in the interpretability of these learning models, which can obscure potential security risks. Among these risks are backdoor attacks, a sophisticated and deceptive threat where attackers induce malicious behaviors in the model under specific triggers.</div><div>In response to the growing need for integrity and reliability in these models, this work assesses the vulnerability of state-of-the-art IoT malware classification models to backdoor attacks. Given the complexities of attacking model-based classifiers, we propose a novel trigger generation framework, B-CTG, supported by a specialized training procedure. This framework enables B-CTG to dynamically poison or attack samples to achieve specific objectives. From an attacker’s perspective, the design and training of B-CTG incorporate knowledge from the IoT domain to ensure the attack’s effectiveness.

Results from the main evaluation demonstrate that the proposed attack strategy can achieve high success rates even with low poisoning ratios, though stability remains a concern. Additionally, the inconsistent trends in model performance suggest that designers may struggle to detect the poisoned state of a model based on its performance alone. The transferred setting highlights the critical importance of model and feature knowledge for successful attack predictions, with feature knowledge proving particularly crucial. This insight prompts further investigation into model-agnostic mitigation methods and their effectiveness against the proposed attack strategy, with findings indicating that stability remains a significant concern for both attackers and defenders.</div></div>","PeriodicalId":51004,"journal":{"name":"Computers & Security","volume":"149 ","pages":"Article 104187"},"PeriodicalIF":4.8,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
