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 ↗678 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.

Privacy-Preserving Federated Learning for Building Energy Forecasting: A Differential Privacy Analysis of Aggregation Strategies ↗
Forecasting hourly electricity consumption across distributed building portfolios is critical for grid management and demand response, yet the sensitivity of granular energy data constrains centralised aggregation. Federated learning (FL) trains models in situ, but the cost of layering formal differential privacy (DP) guarantees atop FL remains underexplored for building-energy workloads. We train a CNN-LSTM forecasting model under three FL aggregation strategies (FedAvg, FedProx, FedBN) across four cumulative privacy budgets (ε ∈ {0.5, 1, 3, 6.5}, δ = 10−5) over a federation of 50 commercial…

Research on a New Lightweight Authentication Technology for Power Communication Networks Based on Reconfigurable Intelligent Surface and Meta-Learning ↗
With the expansion of new power communication networks, massive single-antenna power Internet of Things (IoT) terminals face severe security access challenges. Conventional cryptography-based authentication can impose non-negligible computational, memory, and energy overhead on resource-constrained devices, while multi-antenna-aided Physical-Layer Authentication (PLA) cannot generate distinguishable spatial features to resist Sybil attacks for single-antenna nodes. Moreover, heterogeneous power terminals and complex environments lead to high labeling costs and poor adaptability in deep learnin…

Terminal-Assisted Web Authentication for Shared Devices with BLE-Based Confirmation Gating ↗
In shared-device scenarios, terminal-assisted Web authentication reduces credential exposure by keeping authentication credentials on a user-carried mobile terminal. However, existing methods struggle to minimize mobile interaction while protecting against account misuse by other users of the shared device. This study proposes a session-bound, terminal-assisted Web authentication method that uses Bluetooth Low Energy (BLE) proximity evidence to adaptively tune user interaction. The method decouples identity verification from proximity-based interaction tuning: identity is verified via the mobi…

RGB-D Image Encryption Using a Hyperchaotic System and Quaternion Gyrator Transform ↗
An RGB-D image encryption scheme is presented by combining a newly constructed 4D-ICTM hyperchaotic system with a reformulated quaternion gyrator transform (QGT). The proposed 4D-ICTM dynamics arise from the nonlinear combination of the ICMIC and Chebyshev maps with the tanh function and modulo operation. Their dynamical and statistical properties are examined using Lyapunov exponents, bifurcation diagrams, histograms, autocorrelation analysis, and correlation-dimension computation. To handle the heterogeneous RGB-D data, a dedicated preprocessing procedure converts the RGB channels and 16-bit…

CVE-2026-87902: WordPress Core Remote File Inclusion Vulnerability ↗
WordPress Core contains a remote file inclusion vulnerability which could allow an unauthenticated attacker to make page-template resolution include a chosen readable local `.php` file outside the active theme directories, leading to remote code execution. Required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product i

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.
