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 ↗672 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.

Secure image encryption and authentication using Gaussian elliptic curve and complex invertible matrix ↗
Abstract Image transmission in security-critical applications requires strong confidentiality, integrity, and key management. This paper proposes a Chaotic Complex Elliptic Curve-based Secure Image Encryption (CCEC-SIE) scheme operating in the Gaussian domain. By extending elliptic curve cryptography to Gaussian integers, the proposed framework significantly enlarges the cryptographic space without increasing the underlying prime size. Enhanced one-dimensional chaotic maps, including the Iterative Tent and Logistic Maps, are employed to construct a Complex Self-Invertible Key Matrix (CIKM), en…

Automatic binary security classification of arabic mobile app reviews using transformer models and active learning ↗
Mobile application user reviews provide valuable insights into user-reported issues, including security concerns that are critical for software engineering activities such as requirements analysis and system design. However, existing research has largely focused on English reviews and lacks systematic approaches for identifying security-related feedback in Arabic, a low-resource language in this domain. In this paper, we address this gap by developing an integrated approach for automated binary classification of security-related versus non-security-related Arabic mobile app reviews, grounded i…

Neuro-fault recognition-based cybersecurity framework for cardio-hydro-electromechanical stimulators ↗
The modern bio-medical systems are equipped with communication networks for remote control and monitoring purposes. However, the networked systems are susceptible to cyber-attacks, which degrade system operation. This work addresses the cybersecurity problem of cardio-hydro-electromechanical stimulator (C-HEMS) under measurement tampering attacks. To do this, a safety-constrained cyber defense mechanism has been developed to ensure the security of C-HEMS system under such threats under two steps: (i) identification phase: a neuro-fault recognition scheme is proposed to identify tampering attac…

Multi‐Dimensional Physical‐Layer Security via Digitally Mediated Space–Time Modulation ↗
ABSTRACT Modern sensing and communication systems increasingly operate in congested electromagnetic environments, where suppressing the observability of radiated signals at unintended receivers is essential for secure operation. Space–time modulation offers a powerful means of shaping radiation for secure transmission by exploiting temporal degrees of freedom, but its achievable control is often limited by hardware‐bound modulation dimensions, with further expansion incurring substantial system complexity. Here, we propose a new digitally mediated space–time modulation paradigm that significan…

RCMS: a robust cybersecurity metamodel for cloud computing in Saudi Arabia ↗
Abstract Cloud computing underpins Saudi Arabia’s Vision 2030, making cybersecurity an escalating national concern. Existing security frameworks incorporate relevant measures but lack cloud-specific constructs in identified areas and are not localized to Saudi regulatory requirements. This study has two objectives: to review existing cybersecurity approaches for cloud computing using the PRISMA methodology, appraising their strengths and weaknesses against a stated rubric; and to develop a high-level cybersecurity metamodel for cloud computing in Saudi Arabia, designated RCMS, through a metamo…

Base Semantics—A Novel Approach for Minimizing Malware Detection Rules ↗
ABSTRACT The rapid evolution of malware variants has increasingly undermined traditional signature‐based detection techniques, which are easily evaded through obfuscation and polymorphism that preserve malicious functionality. This challenge is particularly acute in Internet of Things (IoT) environments, where device heterogeneity, resource constraints, and large‐scale deployment limit the adoption of heavyweight security mechanisms. As a result, IoT systems have become prime targets for sophisticated malware campaigns, including botnets, ransomware, and spyware, highlighting the need for adap…

Sensitive-aware graph neural network for privacy leakage traceability in scan-to-order systems ↗
Abstract Scan-to-order systems route user data through merchants, payment gateways, cloud services, and third-party analytics providers in a single transaction flow. This multi-entity architecture makes privacy leakage difficult to trace: a sensitive record may travel five or six hops before reaching an unauthorised party, and the intermediate steps look identical to legitimate business traffic. Existing rule-based provenance tools and static graph models break down at this scale because they treat every data flow as equally important and cannot attribute causal responsibility to specific edge…

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.
