AI-powered defense for an AI-accelerated threat landscape

We are at an inflection point in cybersecurity. Recent advances in AI model capabilities are changing how vulnerabilities are discovered and exploited. AI models can autonomously discover weaknesses, chain multiple lower-severity issues into working end-to-end exploits, and produce working...

Making opportunistic cyberattacks harder by design

This is part of a series of blogs and interviews conducted with our Microsoft Deputy CISOs , in which we surface a number of mission-critical security recommendations and best practices that businesses can enact right now and derive real meaningful benefits from. In this article, Ilya Grebnov,...

Challenges and Future Directions in Agentic Reverse Engineering Systems

Agentic systems built on large language models LLMs are increasingly being used for complex security tasks, including binary reverse engineering RE. Despite recent growth in popularity and capability, these systems continue to face limitations in realistic settings. Cutting-edge systems still fai...

CVE-2026-40093

nimiq-blockchain provides persistent block storage for Nimiq's Rust implementation. In 1.3.0 and earlier, block timestamp validation enforces that timestamp = parent.timestamp for non-skip blocks and timestamp == parent.timestamp + MINPRODUCERTIMEOUT for skip blocks, but there is no visible upper...

GHSA-49XC-52MP-CC9J nimiq-blockchain is missing a wall-clock upper bound on block timestamps

Impact Block timestamp validation enforces that timestamp = parent.timestamp for non-skip blocks and timestamp == parent.timestamp + MINPRODUCERTIMEOUT for skip blocks, but there is no visible upper bound check against the wall clock. A malicious block-producing validator can set block timestamps...

CVE-2026-40093

The CVE describes a wall-clock upper bound omission in Nimiq’s block timestamp validation for the nimiq-blockchain Rust implementation (1.3.0 and earlier). Specifically, non-skip blocks enforce timestamp >= parent.timestamp and skip blocks enforce timestamp == parent.timestamp + MIN_PRODUCER_T...

GHSA-J3W3-P6MR-3HRH DynFuture Drop Can Construct a Dangling Reference

DynFuture is unsound because its Drop implementation transmutes a trait-object reference into unrelated reference types, which constructs an invalid reference from trait object metadata. This issue was reproduced against dyn-future 3.0.4 under Miri. The crate is unmaintained...

New FCC router ban could leave home networks less secure

On Monday, the Federal Communications Commission FCC updated its list of insecure equipment, outlining its reasons for adding all consumer-grade routers made outside the US. Effectively, this would stop foreign-made routers from being imported unless their manufacturers obtain an exemption, due t...
