AI-driven attacks now automate reconnaissance, generate malware variants, and evade detection at a speed that overwhelms traditional defenses. Corelight explains how network detection and response (NDR) provides the visibility and behavioral insights SOC teams need to spot and stop these fast-moving threats. […] Read More
Notepad++ version 8.8.9 was released to fix a security weakness in its WinGUp update tool after researchers and users reported incidents in which the updater retrieved malicious executables instead of legitimate update packages. […] Read More
Hackers are exploiting a new, undocumented vulnerability in the implementation of the cryptographic algorithm present in Gladinet’s CentreStack and Triofox products for secure remote file access and sharing. […] Read More
An unpatched zero-day vulnerability in Gogs, a popular self-hosted Git service, has enabled attackers to gain remote code execution on Internet-facing instances and compromise hundreds of servers. […] Read More
Cybersecurity researchers have disclosed details of a new fully-featured Windows backdoor called NANOREMOTE that uses the Google Drive API for command-and-control (C2) purposes. According to a report from Elastic Security Labs, the malware shares code similarities with another implant codenamed FINALDRAFT (aka Squidoor) that employs Microsoft Graph API for C2. FINALDRAFT is attributed to a Read […]

Grounding the Ungrounded: A Spectral-Graph Framework for Quantifying Hallucinations in Multimodal LLMscs.AI updates on arXiv.org arXiv:2508.19366v4 Announce Type: replace-cross
Abstract: Hallucinations in LLMs–especially in multimodal settings–undermine reliability. We present a rigorous information-geometric framework, grounded in diffusion dynamics, to quantify hallucinations in MLLMs where model outputs are embedded via spectral decompositions of multimodal graph Laplacians, and their gaps to a truth manifold define a semantic distortion metric. We derive Courant-Fischer bounds on a temperature-dependent hallucination profile and use RKHS eigenmodes to obtain modality-aware, interpretable measures that track evolution over prompts and time. This reframes hallucination as quantifiable and bounded, providing a principled basis for evaluation and mitigation.
