Nightmare Eclipse drops claimed BitLocker bypass for Microsoft Windows

Nightmare Eclipse has released a new zero-day vulnerability exploit called GreatXML, which allows unrestricted access to BitLocker volumes on Windows systems that have previously run a Microsoft Defender Offline scan. This discovery was made in four hours and adds to Nightmare Eclipse's total of eight zero-day vulnerabilities. Microsoft is investigating the claims related to another exploit, RoguePlanet, but has not commented on GreatXML or provided a patch timeline. Nightmare Eclipse, rumored to be a former Microsoft employee, has faced backlash from the security community for previous disclosures and has vowed to continue releasing vulnerabilities. Security expert Will Dormann has raised concerns about the practicality of the GreatXML exploit, noting that it requires administrative access and questioning the accuracy of the instructions provided by Nightmare.

New Windows Zero-Day Exploit ‘RoguePlanet’ Released

A new zero-day exploit named RoguePlanet has been discovered targeting Microsoft’s Windows operating system, disclosed by security researcher Nightmare Eclipse. The exploit allows local privilege escalation (LPE) by exploiting a race condition in Microsoft Defender and can facilitate remote code execution (RCE) through deceptive .vhd(x) files. RoguePlanet may also bypass BitLocker encryption. The proof-of-concept has been tested on Windows 10 and Windows 11 systems but does not function on Windows Server, although the researcher believes all Windows Server versions are vulnerable. Following its release, RoguePlanet was confirmed by other researchers to spawn a command prompt with SYSTEM privileges on patched computers. This disclosure comes after Microsoft released patches for earlier exploits by Nightmare Eclipse, including GreenPlasma and YellowKey. The researcher has expressed dissatisfaction with Microsoft’s vulnerability disclosure process, alleging legal action against them and the suspension of their GitHub account, leading to the publication of RoguePlanet under a new account.

Windows 11 Settings You Should Change in 2026：A 9-Point Speed, Privacy, and Security Checklist

On June 9, 2026, Microsoft released a major security update addressing around 200 vulnerabilities, including three critical zero-day exploits. This update coincides with the expiration of Secure Boot certificates that have been in place since 2011. Users are advised to review their Windows 11 settings to ensure security and optimization during this transition. Key actions include installing the June update, enabling faster delivery of updates, turning on Core Isolation memory integrity, activating Controlled folder access against ransomware, confirming drive encryption, disabling the advertising ID, minimizing diagnostic data, auditing camera and microphone permissions, disabling unnecessary startup applications, enabling Storage Sense, adjusting power mode settings, and tuning visual effects for better performance.

A Star Trek horror game is just wild enough to work, but not the one Bloober Team is making

Bloober Team is developing a horror game set in the Star Trek universe, featuring the Bajoran character Ro Laren. The project combines horror elements with the traditionally optimistic themes of Star Trek, creating a mix of excitement and skepticism among fans. Ro Laren's character, known for her conflict with Starfleet ideals, aligns with the darker themes of the game, but her story may challenge the franchise's core values of unity and hope. The success of unconventional Star Trek projects suggests the franchise can adapt to new formats, and anticipation builds around how Bloober Team will merge their style with Star Trek's spirit.

NFCShare Android malware spreads via fake banking app updates on GitHub

New variants of the NFCShare Android malware are disguised as fake updates for legitimate banking applications and are targeting customers of various banks in Europe through a phishing campaign to steal sensitive payment card data. The malware prompts victims to place their cards near the NFC chip of their mobile devices, using Android’s IsoDep interface to read card information, including card number, type, expiry date, and a 4-digit PIN. The stolen data is exfiltrated to the attacker’s command-and-control host via a WebSocket channel. Recent attacks began on May 14, with victims directed to a phishing site that impersonates a legitimate bank and then to a GitHub repository hosting a malicious APK file. The repository has hosted 56 unique APKs impersonating banking applications primarily from Italy and Spain. The malware has evolved from initially targeting Deutsche Bank in Germany to a broader range of banks. The latest version features malformed APK packaging to complicate automated analysis. Users are advised to download banking applications only from Google Play and to be cautious of verification requests that ask for NFC card scans.

How We Test Antivirus and Security Software

Most software applications clearly indicate their functionality, but the effectiveness of antivirus utilities is often less tangible. PCMag rigorously evaluates antivirus products through comprehensive tests that validate their claims, including real-world malware samples and various protective measures. Each antivirus tool is assessed based on its on-demand scanner and real-time monitor capabilities. PCMag compiles fresh malware samples annually, analyzing them to ensure they are suitable for testing. The testing process includes evaluating malware-blocking capabilities and web-level protection against known malware-hosting sites. Phishing site detection is also tested using recent URLs, and antispam testing has been simplified due to the effectiveness of email providers. Performance impact tests have been discontinued as modern security suites show improved efficiency. Firewall protection is evaluated through program control, exploit defenses, and overall resilience against malware. Parental control features are tested for effectiveness in content filtering and monitoring. Ransomware protection is assessed by releasing real-world samples in a controlled environment. PCMag monitors independent antivirus lab tests from various organizations, including AV-Test, AV-Comparatives, SE Labs, MRG-Effitas, and AVLab, to inform their reviews. An aggregate testing score is calculated to summarize lab results. Testing methodologies do not include VPN evaluations, which are covered separately.

PHANTOMPULSE RAT Uses UAC Bypass to Hijack Windows Systems

PHANTOMPULSE is a remote access trojan (RAT) used as a final payload in multi-stage attacks targeting Windows environments. It employs advanced post-exploitation techniques, including process injection, User Account Control (UAC) bypass, and a decentralized blockchain-based command-and-control (C2) mechanism. The malware utilizes three process injection techniques: module stomping, manual DLL mapping, and debug-driven execution. It avoids detection by using direct system calls instead of standard Windows APIs and incorporates a hardware breakpoint mechanism to disable security protections like AMSI and ETW. PHANTOMPULSE retrieves its C2 server address from Ethereum-based transaction data but has a vulnerability that allows defenders to hijack communication. It achieves persistence through scheduled tasks and supports self-healing capabilities. Privilege escalation is done using the "schuac" UAC bypass technique. The malware conducts system reconnaissance focusing on cryptocurrency wallets and messaging apps but does not directly steal credentials. It shows signs of AI-assisted development and shares tactics with DPRK-aligned threat groups, particularly in targeting cryptocurrency platforms.
