Earlier sources: Security
Digital security protects systems, software, accounts, and information from misuse. Explore cybersecurity, vulnerabilities, threat intelligence, cryptography, privacy, and identity, with links to the underlying advisories and research.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗637 classified signals in the fourteen-day window. Recent momentum: steady. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Deterministic Mamdani fuzzy-controlled KAA and hybrid logistic–sine chaotic image encryption with AES S-box substitution ↗
In this digital era, the rapid growth of imaging applications in cloud, medical, and IoT environments requires secure and efficient encryption techniques capable of addressing pixel redundancy and statistical correlations. This study proposes a deterministic entropy-controlled image encryption framework that integrates Mamdani fuzzy inference, hybrid chaotic systems, and selective nonlinear substitution. The proposed framework utilizes image statistical characteristics, including entropy, mean, and contrast, to adaptively regulate chaotic initialization, substitution probability, and diffusion…

Assessing information security policy compliance: a managerial perspective on leadership and awareness ↗
Purpose Insider non-compliance with information security policies (ISPs) remains a significant organisational risk. This study aims to examine how leadership styles and information security awareness (ISA) dimensions influence employees’ social cognitive beliefs (SCBs) and, ultimately, their information security policy compliance (ISPC) intention. Design/methodology/approach Guided by the theory of planned behaviour (TPB), a quantitative survey was conducted among professionals working in organisations with established ISPs. A total of 205 valid responses were analysed. Findings Attitude was t…

ZD-HybridNet integrates transformer and LSTM models for explainable zero day cyber attack detection ↗
The exponential growth of interconnected systems has dramatically expanded the attack surface of modern networks, making zero-day attacks, which exploit previously unknown vulnerabilities, a critical threat to organizational security. Traditional signature-based and anomaly detection systems often struggle to identify such previously unseen attack patterns, and while deep learning (DL) offers promising detection capabilities, existing DL-based intrusion detection systems (IDS) suffer from poor generalization to novel attacks and operate as opaque black boxes, lacking interpretability for secur…

Cybersecurity of Smart Sensing Insole Systems: A Threat Modelling Approach to Understanding Security Vulnerabilities ↗
Smart sensing insoles are emerging medical IoT devices used primarily in diabetes care to monitor foot pressure, temperature and gait for preventing diabetic foot ulcers and lower-limb amputation. Despite growing healthcare use, the cybersecurity threats to these systems have received limited systematic analysis in the literature. This study aimed to provide a detailed threat modelling analysis of smart insole systems. The study developed a representative smart insole system architecture using public information, the literature, and manufacturer input. A data flow diagram mapped devices, proce…

Ceramide stress defines a targetable metabolic vulnerability in IDH1-mutant oligodendroglioma ↗
Abstract Oligodendroglioma is genetically defined by mutations in isocitrate dehydrogenase 1 or 2 (IDH1/IDH2) and 1p/19q codeletion. These tumors exhibit a distinct metabolic state driven by the oncometabolite D-2-hydroxyglutarate, which shifts the sphingosine-1-phosphate–ceramide rheostat toward ceramide accumulation. Taking advantage of this intrinsic metabolic state, we investigated whether further elevating ceramide levels through inhibition of acid ceramidase—a key enzyme that degrades ceramide to sphingosine—could promote apoptotic cell death. Analysis of patient datasets demonstrated th…

Vulnerability-aware reinforcement learning scheduling of AI data centers under typhoon-induced thermal coupling ↗
The rapid growth of AI data-center loads, amplified by typhoon-induced thermal coupling between workloads and cooling systems, poses new challenges to transmission grid vulnerability assessment and scheduling. This paper develops a vulnerability-aware reinforcement-learning (RL) scheduling framework that integrates a measured-data-driven AI load model, a typhoon-day temperature–PUE–cooling model, a seven-indicator vulnerability assessment covering physical, structural, and AI-specific dimensions, and RL scheduling via PPO, SAC, and TD3 with a PTDF-based top- K branch-selection mechanism that c…

Mitochondrial Remodeling and Impaired Bioenergetics Define Neuronal Vulnerability in Fragile X-Related Disorders ↗
Fragile X syndrome (FXS) and related conditions associated with FMR1 gene alterations have increasingly been linked to mitochondrial dysfunction, although most available evidence derives from peripheral cell models. Whether these abnormalities also occur in disease-relevant neuronal populations remains largely unknown. Building on our previous observations in patient-derived fibroblasts, we investigated mitochondrial structure and function in neurons differentiated from induced pluripotent stem cells (iPSCs) generated from individuals with FXS and carriers of unmethylated full mutations, using…

Single-nucleus transcriptomics uncovers region-specific molecular features underlying selective aging vulnerability of cholinergic neurons ↗
Cholinergic neurons exhibit functional and molecular heterogeneity across the basal forebrain (BF), midbrain (MB), and brainstem (BS), while the aging-associated transcriptional features remain poorly characterized. Here, we performed single nucleus RNA sequencing (snRNA-seq) on 108,062 nuclei from the MS/VDB, HDB/SI, PPTG/LDTG, 7N, and 12N in adult and aged mice. BF cells showed greater age-associated transcriptomic alterations than MB and BS cells, with pronounced region-specific divergence among cholinergic neurons. Intercellular communication analysis revealed BF-specific age-related chang…

SHAP-guided adaptive feature weighting for phishing URL detection with a federated learning extension ↗
Abstract Machine-learning phishing URL detectors routinely report accuracies above 97%, yet four weaknesses undermine these results: absent statistical testing, unfair latency benchmarking, uninterpretable predictions, and an inability to use data held privately across organisations. We address all four on the Hannousse-Yahiouche benchmark (11,430 URLs, 87 features). We introduce the SHAP-Guided Adaptive Feature Weighting (SAFW) layer, a trainable component initialised from XGBoost SHAP scores and evaluate seven architectures (including a DistilBERT reference case) with 10-fold cross-validatio…

Assessing power system vulnerability to climate-related stressors and shocks: The case of Indonesia ↗
Climate change and extreme weather are increasing the vulnerability of power systems globally, particularly in emerging economies such as Indonesia. Yet, existing studies often assess these impacts in isolation, focusing on individual components or specific hazards, leaving system-level effects—at provincial and national scales—under-examined. To address this gap, we develop an integrated, spatially explicit approach to assess an energy system's climate-related vulnerabilities and their impacts, and apply the approach to Indonesia. We quantify climate-based vulnerabilities in generation and tr…

How to assess evidence about Security
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
