CVE-2026-45585: YellowKey BitLocker Bypass

BitLocker, a security feature for data protection, has a vulnerability identified as CVE-2026-45585, also known as YellowKey, which allows unauthorized access to encrypted data on Windows 11 versions 24H2, 25H2, 26H1, and Windows Server 2025. This flaw does not compromise BitLocker’s encryption but affects the recovery environment supporting it. The vulnerability can be exploited locally through the Windows Recovery Environment (WinRE) by an attacker with physical access, who can trigger an unrestricted shell and access the BitLocker-protected volume. Microsoft has provided two mitigation strategies: modifying the WinRE image to remove the autofstx.exe entry and transitioning from TPM-only protection to a TPM+PIN requirement at startup. The exploit poses challenges for detection, as it occurs pre-boot and currently lacks vendor-published indicators of compromise. Organizations using BitLocker for unattended devices are particularly at risk, as the vulnerability can lead to loss of confidentiality if an attacker gains access before the legitimate user.

What the Tech: Phone antivirus apps |Helpful protection or a scam?

Most individuals do not require antivirus apps on their smartphones, as the primary threats have shifted from traditional viruses to scams and deceptive practices. iPhones utilize app isolation, making them less susceptible to conventional viruses but vulnerable to scams like phishing and fraudulent messages. Android phones allow sideloading, increasing the risk of malware from unofficial sources. The main threats include phishing texts, fake login pages, scam calls, reused passwords, and social engineering tactics. To enhance security, users should keep their phones updated, use strong passwords, enable two-factor authentication, avoid suspicious links, and refrain from installing apps from unknown sources. Antivirus apps may be helpful in specific situations, such as frequent link tapping or downloading files from unfamiliar websites, with reputable companies offering mobile security solutions focused on scam detection and account safety.

Microsoft Defender Zero-Day Vulnerabilities RedSun and UnDefend Actively Exploited on Windows 10, 11, and Server (April 2026 CVE Analysis)

In April 2026, two zero-day vulnerabilities, RedSun and UnDefend, were discovered in Microsoft Defender, affecting Windows 10, Windows 11, and Windows Server platforms. These vulnerabilities allow attackers to escalate privileges to SYSTEM and bypass Defender’s protections. RedSun exploits a flaw in Defender's remediation process, enabling low-privileged users to overwrite critical system files. UnDefend allows attackers to disrupt Defender’s updates, keeping it outdated and ineffective. Both vulnerabilities are actively being exploited, with attackers leveraging them to gain persistent access and deploy ransomware. The primary targets are organizations using Windows systems with Defender enabled, particularly in sectors like finance, healthcare, and government. Mitigation strategies include applying updates for related vulnerabilities, monitoring for suspicious activities, and implementing additional security measures.

What the Tech? Antivirus protection for your smartphone

Most users do not require an antivirus app on their smartphones, as the predominant threats are scams such as phishing texts and fraudulent websites rather than traditional viruses. iPhones operate on a design that isolates apps, limiting the effectiveness of antivirus software, while Android devices allow sideloading, which can increase the risk of malware. The real danger lies in deception tactics used by cybercriminals, making personal account security more important than antivirus software. To enhance security, users should keep their operating systems updated, use strong passwords, enable two-factor authentication, avoid suspicious links, and refrain from installing apps from unknown sources. Antivirus apps may be beneficial for users who frequently click on unverified links, download files from unfamiliar sites, or engage in Android sideloading. Reputable security apps focus on scam detection and web protection rather than traditional virus scanning.

Фанаты Minecraft тайно скопировали 24 терабайта данных с легендарного сервера 2b2t – архив миллиона блоков скоро раздадут через торрент

A group of Minecraft enthusiasts has completed a digital archaeology project, mapping and archiving the oldest anarchy server, 2b2t, resulting in 24 terabytes of data. This data will be released as a torrent in the coming weeks. The 2b2t server has been operational for 16 years and is known for its lack of rules and bans. The team successfully archived various areas of the server, including: - Overworld area of 1,024,000² blocks (December 25, 2025 – April 13, 2026) - Overworld area of 512,000² blocks (November 11, 2024 – December 12, 2024) - End area of 256,000² blocks (January 23, 2026 – February 15, 2026) - Nether area of 100,000² blocks (June 9, 2025 – June 14, 2025) The team plans to release high-resolution renders and data analysis tables alongside the archive. Open-source tools for the archive are available on GitHub, and updates can be followed via Discord and Patreon.

MSHTA abuse helps malware hide in Windows processes

Bitdefender's research highlights the use of Microsoft's MSHTA utility in malware attacks, noting its default activation in Windows systems. Cybercriminals exploit MSHTA to execute malicious scripts under the guise of legitimate processes, linking it to various malware families like LummaStealer and PurpleFox. The study reports a rise in MSHTA-related detections, indicating a shift towards "living-off-the-land" tactics that utilize legitimate tools to evade security alerts. Social engineering is identified as a common entry point for attacks, employing deceptive methods such as fake software downloads and phishing links. MSHTA can retrieve and execute additional payloads through multi-stage chains, complicating detection efforts. The attacks target sensitive information, including credentials and financial data, and the continued presence of MSHTA poses risks as it allows threat actors to conceal malicious actions. To mitigate these threats, organizations are advised to restrict or disable legacy scripting tools and exercise caution with untrusted downloads. The report emphasizes the challenge of detecting unusual behaviors associated with legitimate utilities in the context of cyber threats.

Trapdoor Android Ad Fraud Scheme Hit 659 Million Daily Bid Requests Using 455 Apps

Cybersecurity researchers have identified an ad fraud and malvertising operation called Trapdoor, targeting Android users with 455 malicious applications and 183 command-and-control domains. Users often download these disguised apps, which initiate malvertising campaigns and lead to further downloads of malicious applications. At its peak, Trapdoor generated 659 million bid requests daily, with over 24 million downloads of the associated apps, primarily from the United States. The operation exploits install attribution tools to activate malicious activities only for users acquired through fraudulent ad campaigns, while suppressing such behavior for organic downloads. Trapdoor employs advanced evasion techniques, including obfuscation and impersonation of legitimate software, to avoid detection. Google has removed the identified malicious apps from the Play Store in response to the threat.
