A proof-of-concept exploit for CVE-2026-20817, a local privilege escalation vulnerability in the Windows Error Reporting (WER) service, has been released by security researcher oxfemale on GitHub. This vulnerability allows low-privileged users to gain SYSTEM-level access through crafted Advanced Local Procedure Call (ALPC) messages. The flaw is located in the WER service's SvcElevatedLaunch method, which fails to validate caller privileges before executing WerFault.exe with user-supplied command line parameters. The CVSS v3.1 base score for this vulnerability is 7.8, indicating a high severity level. It affects unpatched versions of Windows 10, Windows 11, Windows Server 2019, and Windows Server 2022 prior to the January 2026 update. Demonstrations have shown successful exploitation on Windows 11 23H2. Security teams are advised to monitor for unusual processes related to WerFault.exe, investigate missing SeTcbPrivilege in SYSTEM tokens, and review WER-related activities from low-privilege users. Immediate application of the January 2026 security patches is recommended, and a temporary workaround involves disabling the WER service.

Cybersecurity researchers have identified a new Android trojan named Massiv, designed for device takeover attacks targeting financial theft. It disguises itself as IPTV applications and poses risks to mobile banking users by allowing operators to remotely control infected devices for fraudulent transactions. The malware was first detected in campaigns targeting users in Portugal and Greece, with features including screen streaming, keylogging, SMS interception, and fake overlays for credential theft. One campaign specifically targeted the gov.pt application to deceive users into providing sensitive information. Massiv can execute various malicious actions, such as altering device settings, sending device information, and downloading malicious files. It is distributed through dropper applications that mimic IPTV services, often via SMS phishing. The malware operates in the background while the dropper appears as a legitimate app. Recent campaigns have focused on regions like Spain, Portugal, France, and Turkey, indicating a growing threat landscape. The operators of Massiv are developing it further, suggesting intentions to offer it as a Malware-as-a-Service.

A cyber-espionage campaign is utilizing the XWorm Remote Access Trojan (RAT) to infiltrate systems via phishing emails and a Microsoft Office vulnerability (CVE-2018-0802). XWorm, first detected in 2022, allows attackers remote control over infected computers for surveillance and data theft. The campaign uses business-oriented phishing emails with malicious Excel attachments that exploit the vulnerability to execute a fileless attack. The malware connects to a command-and-control server, encrypting communications and transmitting system details. XWorm features a plugin architecture with over 50 modules for various malicious activities, including credential theft and DDoS attacks. Security experts highlight the ongoing risk of legacy software vulnerabilities and recommend patching outdated components.

Microsoft has identified at least six zero-day vulnerabilities in Windows and Microsoft Office that were actively being exploited by hackers before patches were released. These vulnerabilities allow attackers to compromise systems with minimal user interaction, such as clicking on malicious links or opening compromised Office documents. Notable examples include a Windows Shell Security Bypass (CVE-2026-21510) and an Office File Exploit that can execute malicious code. The vulnerabilities pose serious risks, including active exploitation, remote code execution, and the potential for malware installation and credential theft. Microsoft has released security patches to address these vulnerabilities, and users are urged to install them immediately. The affected systems include all supported versions of Windows and Microsoft Office applications. Users are advised to install updates, be cautious with emails and links, enable security tools, and keep software up to date.

A new Android malware named Albiriox has emerged, marketed as malware-as-a-service (MaaS). It features a hard-coded list of over 400 applications, including banking and cryptocurrency platforms, and is distributed through social engineering tactics using dropper applications. Initially advertised in late September 2025, it became a full MaaS offering by October, with Russian-speaking threat actors behind its development. Albiriox allows remote control of compromised devices via an unencrypted TCP socket connection and Virtual Network Computing (VNC), enabling attackers to extract sensitive information and perform overlay attacks for credential theft. One campaign targeted victims in Austria using German-language lures and counterfeit Google Play Store listings. Albiriox also utilizes Android's accessibility services to bypass security measures and employs a novel distribution strategy involving a counterfeit website that collects phone numbers. Additionally, another Android MaaS tool, RadzaRat, was introduced, masquerading as a file management utility while offering extensive surveillance and remote control capabilities. RadzaRat can log keystrokes and maintain persistence through specific permissions, highlighting a trend in the availability of sophisticated cybercrime tools.

Microsoft announced an update for FIDO2 security keys on Windows 11, introducing a new prompt for users to set up a PIN during authentication. The rollout began with preview update KB5065789 on September 29, 2025, for OS Builds 26200.6725 and 26100.6725, and was completed with security update KB5068861 on November 11, 2025, for OS Builds 26200.7171 and 26100.7171. This update affects sign-ins where a Relying Party (RP) or Identity Provider (IDP) requests User Verification set to “Preferred” for keys without a PIN, in accordance with WebAuthn specifications. Users must now set up a PIN during authentication flows, not just during registration. To avoid PIN prompts, RPs or IDPs can set “userVerification” to “discouraged.” There is no option to roll back the changes.
