🔐 In this essay Bruce Schneier (with Davi Ottenheimer) argues that data integrity must be the foundational trust mechanism for autonomous AI agents operating in Web 3.0. He frames integrity as distinct from availability and confidentiality, and breaks it into input, processing, storage, and contextual dimensions. The piece describes decentralized protocols and cryptographic verification as ways to restore stewardship to data creators and offers practical controls such as signatures, DIDs, formal verification, compartmentalization, continuous monitoring, and independent certification to make AI behavior verifiable and accountable.

⚠️ Unit 42 researchers Tony Li and Hongliang Liu introduce Logit-Gap Steering, a new framework that exposes how alignment training produces a measurable refusal-affirmation logit gap rather than eliminating harmful outputs. Their paper demonstrates efficient short-path suffix jailbreaks that achieved high success rates on open-source models including Qwen, LLaMA, Gemma and the recently released gpt-oss-20b. The findings argue that internal alignment alone is insufficient and recommend a defense-in-depth approach with external safeguards and content filters.

Unit 42 observed real-world credential-stealing pages and misuse of trial accounts lacking guardrails. Customers are advised to use Advanced URL Filtering and Advanced DNS Security and report incidents to Unit 42 Incident Response.

⚠️ EchoLink is a newly identified zero-click vulnerability in Microsoft 365 Copilot that enables silent exfiltration of enterprise data without any user interaction. This class of attack bypasses traditional click- or download-based defenses and moves laterally at machine speed, making detection and containment difficult. Organizations relying solely on native tools or fragmented point solutions should urgently reassess their exposure and incident response readiness.

🧠 Researchers at Carnegie Mellon University demonstrated that leading large language models (LLMs), by themselves, struggle to execute complex, multi-host cyber-attacks end-to-end, frequently wandering off-task or returning incorrect parameters. Their proposed solution, Incalmo, is a structured abstraction layer that constrains planning to a precise set of actions and validated parameters, substantially improving completion and coordination. The work highlights both enhanced offensive potential when LLMs are scaffolded and urgent defensive challenges for security teams.

📅 In episode 430 of Smashing Security, host Graham Cluley and guest Dave Bittner examine a range of security stories, led by a proof‑of‑concept attack that weaponises Google Calendar invites to trigger smart‑home actions.

🔐 CrowdStrike explains how inadvertent 'leakage' — when dependent or correlated observations are included in training — can inflate machine learning performance and undermine threat detection. The article shows that blocked or grouped data splits and blocked cross-validation produce more realistic performance estimates than random splits. It also highlights trade-offs, such as reduced predictor-space coverage and potential underfitting, and recommends careful partitioning and continuous evaluation to improve cybersecurity ML outcomes.

🛠️ Martin Lee recounts a weekend experiment using an AI agent to assist with a personal software project. The model provided valuable architectural guidance, flawless boilerplate, and resolved a tricky threading issue, delivering a clear productivity lift. However, generated code failed to match real library APIs, used incorrect parameters and fictional functions, and lacked sufficient input validation. After manual debugging Lee produced a working but not security-hardened prototype, highlighting remaining risks.
