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 ↗634 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.

LETHE: Defending against Unauthorized Image-to-Video Generation via Value Diversity Collapse ↗
Image-to-video (I2V) diffusion models can animate a single reference image into high-quality, subject-consistent videos, posing threats of misuse as anyone can turn personal photos into fabricated videos without consent. A promising solution is to proactively add an adversarial perturbation to the image before release, such that videos generated from it would be unfaithful or visually corrupted. However, due to an insufficient understanding of what governs how subsequent frames read the reference image in modern I2V models, existing protections struggle to offer strong protection under common…

Blockchain Security: An Empirical Evaluation of High‐Impact Exploits and Detection Tools ↗
ABSTRACT Blockchain introduced secure, peer‐to‐peer transactions in decentralized environments without reliance on central authorities. However, attackers continue to exploit blockchain projects. Over the past decade, reported blockchain exploit losses have exceeded $24 billion. Although existing research analyzes blockchain vulnerabilities and real‐world incidents, many studies focus on specific vulnerability classes or smart contract issues only. Therefore, we present an empirical study of major blockchain exploits from 2020 to 2025. Based on detailed analysis of these exploits, we introduce…
Live window recorded . This is the ingestion observation time, not the publication or discovery date of each source.
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.
