Microsoft closes RoguePlanet vulnerability in Defender: SYSTEM privileges via the antivirus engine

A vulnerability known as RoguePlanet was identified in Microsoft Defender, tracked as CVE-2026-50656. This flaw allows local privilege escalation to the NT AUTHORITYSYSTEM account, requiring an attacker to have local code execution capabilities. It can be exploited through methods such as opening malicious email attachments. The vulnerability is categorized under CWE-59: “Improper Link Resolution Before File Access” and involves a race condition that affects the Defender engine's operations. RoguePlanet was disclosed by security researcher Nightmare-Eclipse on June 10, 2026, and confirmed by various security firms. Microsoft released a fix in version 1.1.26060.3008 of the Microsoft Malware Protection Engine, which should be installed automatically in standard Windows configurations. Users can verify their engine version using PowerShell. The vulnerability affects both Windows 10 and Windows 11 systems with the June 2026 security updates, and disabling real-time protection does not reliably mitigate it.

I tested Norton Antivirus on my PC – and it found a hidden Trojan in 15 minutes

Norton Antivirus is a well-regarded malware protection tool, consistently ranking among the top in the industry with a robust suite of security features. It has a user-friendly interface similar to Malwarebytes, but intrusive upselling tactics detract from usability. Norton offers comprehensive scanning tools, including Quick Scan, Full Scan, Smart Scan, Targeted Scan, and Startup Scan, which successfully detected a Trojan missed by other antivirus software. Its Scam Protection tools provide alerts for online scams and phishing attempts, and it includes unique features like Deepfake Protection and an AI assistant named Genie. According to MRG Effitas, Norton blocked 98% of malware samples with a 0.33% miss rate, achieving a Level 2 certification. Pricing includes several plans, with Norton 360 Deluxe offering the best value at an introductory price of .99 for the first year, rising to .99 annually. Despite its strengths, the intrusive upselling makes it less recommendable compared to Malwarebytes, although it has unique capabilities in threat detection and a comprehensive suite of security tools.

Patch for Windows Defender 0-day could allow attackers to fill hard disk

A recent Microsoft patch addressing the RoguePlanet vulnerability (CVE-2026-50656) in its Defender security engine has raised concerns about disk space issues for Windows users. The vulnerability allows remote attackers to gain administrative control over Windows 10 and 11 systems. The patch, which updates the Microsoft Malware Protection Engine, is automatically installed without user action. However, it may enable attackers to fill a hard drive by writing excessive data due to changes in the mpengine.dll driver. These changes can cause a data leak of 8 bytes when opening a file and involve new functionalities in SpyNet, which could lead to mass file-writing behavior. Typically, Defender limits file sizes during scanning, but the spynet functions may maintain a local copy of the Zone.Identifier Alternate Data Stream file, potentially exhausting disk space.

A critical Windows 11 and Windows 10 flaw turns Microsoft Defender into a hacker’s best friend

Chaotic Eclipse, also known as Nightmare-Eclipse, bypassed Windows 11's BitLocker security using a USB stick and claimed Microsoft left a backdoor in the system. Following this, Microsoft patched three zero-day exploits named YellowKey, GreenPlasma, and MiniPlasma. Nightmare-Eclipse then revealed another zero-day vulnerability called RoguePlanet, which affects Microsoft Defender on Windows 10 and 11, potentially allowing attackers full control over compromised systems. Microsoft is tracking this vulnerability as CVE-2026-50656 and is working on a security update. Nightmare-Eclipse provided a proof-of-concept exploit and described it as a race condition with variable success rates. Microsoft has promoted Windows Defender as adequate for most users but acknowledged that third-party tools can offer additional protection. The company initially threatened legal action against Nightmare-Eclipse but later decided not to pursue lawsuits against researchers sharing their findings.

A critical exploit bypasses Microsoft Defender in Windows 11 and Windows 10 — so much for “everyday risk protection without additional software”

Security researcher Chaotic Eclipse, known as Nightmare-Eclipse, bypassed Windows 11's BitLocker security using a USB stick and claimed Microsoft intentionally included a backdoor in the feature. Microsoft responded by patching three zero-day exploits disclosed by Nightmare-Eclipse: YellowKey, GreenPlasma, and MiniPlasma, and is monitoring another exploit called RoguePlanet, cataloged as CVE-2026-50656. The RoguePlanet exploit is a race condition with varying success rates on different machines, achieving a 100% success rate on some devices. Microsoft acknowledged that while Windows 11's Defender is generally sufficient for most users, third-party tools can offer additional security features. Tensions between Nightmare-Eclipse and Microsoft have risen, with the company previously considering legal action but now indicating it will not pursue lawsuits against researchers sharing their findings.

Bitdefender vs Norton vs McAfee 2026: 2 Win Gold, 1 Bronze

In 2026, Bitdefender, Norton 360, and McAfee each achieved a perfect score of 18 out of 18 in AV-TEST’s April evaluation. Bitdefender excels in protection technology and has the lightest footprint among paid tiers. Norton 360 offers an unlimited VPN, substantial cloud backup, and LifeLock identity theft protection, achieving the best real-world protection score in 2025. McAfee is strong in identity protection and unlimited-device pricing but falls short in core malware engine performance. Bitdefender is noted for its advanced threat detection and has a low entry price of .99 for its Antivirus Plus. Norton 360 includes an unlimited VPN and up to 250 GB cloud backup, while McAfee+ Ultimate provides identity theft coverage and three-bureau credit monitoring. All three products received perfect scores in AV-TEST’s April evaluation, but independent lab results from AV-Comparatives showed Norton and Bitdefender as Top-Rated Products, while McAfee did not achieve this status. The specifications comparison reveals that Bitdefender supports up to 25 devices, Norton 360 offers unlimited devices, and McAfee also supports unlimited devices. Bitdefender employs Advanced Threat Defense, Norton uses SONAR and Intrusion Prevention, and McAfee utilizes Real Protect. Norton and McAfee received AV-Comparatives Performance awards in 2025 for their light system impact, while Bitdefender did not receive such recognition. Pricing strategies include significant renewal increases after steep first-year discounts. Customer support varies, with Norton and McAfee providing extensive 24/7 support, while Bitdefender offers limited phone support. The ownership structures differ, with Norton under Gen Digital, McAfee as a private entity, and Bitdefender remaining independent. Real-world scenarios suggest Bitdefender is best for single users, Norton 360 or McAfee+ for families, McAfee+ Ultimate or Norton for identity theft concerns, and Norton 360 for privacy-focused users.
