Microsoft's ongoing battle against zero-day exploits

Rule Changes

Tracking and mandating remediation of exploited vulnerabilities

Microsoft released its February 2026 Patch Tuesday update, fixing 58 security flaws including six zero-day vulnerabilities that attackers were already exploiting. The most severe allows attackers to bypass Windows SmartScreen protections, tricking users into running malicious software without seeing the usual security warnings. The United States Cybersecurity and Infrastructure Security Agency (CISA) added all six vulnerabilities to its Known Exploited Vulnerabilities catalog, giving federal agencies until March 3, 2026, to patch their systems.

Microsoft flips the security switch

Rule Changes

Driving industry-wide secure-by-design adoption

On January 12, 2026, millions of Teams users woke up to find their security settings had changed overnight.

Days earlier, the company had quietly expanded Zero-Hour Auto Purge malware removal to all Defender for Office 365 Plan 1 customers, creating a one-two punch of automated threat protection. The moves mark the sharpest turn yet in Microsoft's $34 billion bet that 'secure by default' can repair its battered reputation after Russian and Chinese hackers ransacked its networks in 2023.
