The hidden work of modernizing Malwarebytes

Malwarebytes details its migration of Windows product managed components to .NET 10, citing security, supportability, diagnostics, and performance benefits.

Malwarebytes says it migrated the managed portions of Malwarebytes for Windows to .NET 10 while leaving native drivers and the detection engine untouched. The vendor cites a supported runtime, safer defaults, stronger cryptography, better diagnostics, and JIT/GC performance improvements as benefits. The migration also deprecated Windows 7 support, and the company applies staged rollouts and automated validation because its code runs with elevated privileges on millions of endpoints. No vulnerabilities or incidents are described.

GPT-6 Astra Scores 100% on ExploitBench as OpenAI Blocks PoC Exploit Requests

OpenAI releases GPT-6 Astra, scoring 100% on ExploitBench, but restricts it to secure code review by blocking PoC exploit generation.

OpenAI officially unveiled GPT-6 Astra days after the model reached the "Critical" cybersecurity capability threshold under its Preparedness Framework. The model claims 100% on ExploitBench (versus 78.5% for GPT-5.6 Sol), 98% on FrontierMath Tier 4, and 99.9% on ARC-AGI-3, and demonstrated exploit development including on two zero-days disclosed between June and August 2026. The released version is limited to secure code review and patching and refuses proof-of-concept exploit requests, with less restrictive safeguards planned via OpenAI Daybreak. OpenAI also launched a $1 billion "Daybreak for Frontline Defenders" program for critical infrastructure sectors and a pilot with the US MS-ISAC for public sector and water system defenders.
