Microsoft Defender Zero-Day Attacks Hit Windows as Two Flaws Remain Unpatched

Hackers exploited three Microsoft Defender flaws—BlueHammer, RedSun, and UnDefend—in at least one real-world attack, Huntress reported. Microsoft patched BlueHammer (CVE-2026-33825) this week, but RedSun and UnDefend remain unpatched. Attackers staged the exploit tools after breaching a system via a FortiGate VPN. The identities of the attackers and the targeted organization have not been disclosed.

Windows 11 finally moves closer to ending 32GB FAT32 limit as 2TB formatting reaches Beta

Microsoft is raising the FAT32 volume size limit in Windows Insider Beta and Dev builds, allowing command-line formatting up to 2TB, up from 32GB. The change, previewed April 10, does not apply to the graphical formatter. Updates also speed up disk settings and fix data usage display bugs. FAT32 remains required for some devices despite newer formats dominating most storage.

  • ASX 200 Rises on Miners and Banks but 8,800 Resistance Holds
    May 29, 2026, 8:37 PM EDT. The ASX 200 index ended the week higher, supported by strong gains in miners and banks alongside declining Australian bond yields. Key contributors included BHP (+2.91%), Newmont (NEM, +3.77%), Fortescue Metals (FMG, +2.43%), Rio Tinto (RIO, +2.43%), Commonwealth Bank (CBA, +2.24%), and Goodman Group (GMG, +2.92%). Miners and gold producers were the main drivers, aided by firmer copper prices and stronger bullion. However, the energy sector lagged as crude oil prices softened, and healthcare stocks like CSL and ResMed (RMD) declined. Market participants remain cautious as the index needs a weekly close above 8,800 points to confirm a sustained recovery.
