PAYLOAD ransomware hijacks Windows Group Policy in encryption-less attacks

A sophisticated PAYLOAD ransomware attack targeted a manufacturing organization in the Middle East, exploiting vulnerabilities in Microsoft Active Directory Group Policy. The attackers gained initial access on April 11 by compromising a domain account through the company's FortiGate SSL VPN. By April 13, they escalated privileges to a domain administrator and created a malicious Group Policy Object (GPO) named “PAYLOAD,” which was linked at the root of the domain. This GPO allowed them to distribute a ransom note, change desktop images, display a ransom message during login, and disable the local administrator account. A secondary GPO, “win Firewall Off,” was used to disable Windows Firewall across all profiles. The malicious changes activated on April 14 after system reboots, causing widespread disruption. The attackers also exfiltrated sensitive data, which was later released on the dark web. Kaspersky's investigation found no evidence of file encryption or active malware processes, indicating the attack was contained within Active Directory. Recommendations for organizations include monitoring GPO modifications, implementing multi-factor authentication for VPN access, and safeguarding privileged accounts.

Google Messages is preparing its biggest search overhaul yet

Google Messages is testing a redesign of its search functionality to improve user experience. The search bar will move to the bottom of the home screen, featuring a dynamic visual overview of shared content, including preview rows for images, videos, links, and places. Users will be able to search within specific conversations from the main search page without opening each chat. The search results will display all matching messages on a dedicated results page instead of grouping them by conversation. Links and places will have larger, visually appealing cards, although timestamps and sender names will not be visible. A new media viewer will allow users to swipe through images and videos, enhancing the overall experience.

Windows 11 Update Can Break Active Directory Trust Relationships

A recent security update from Microsoft, KB5124008, has caused disruptions for organizations using on-premises Active Directory, particularly affecting domain-joined Windows 11 devices with Credential Guard. After installing this update, some devices lost their secure trust relationship with the domain, preventing users from logging in with valid credentials. The issue is linked to Machine Identity Isolation, a security feature that enhances machine account credential protection but requires domain controllers to operate at the Windows Server 2025 Domain Functional Level. Organizations that enabled this feature without meeting the prerequisite may experience trust relationship failures. Microsoft has suggested a workaround to disable Machine Identity Isolation and plans to suspend its enforcement in an upcoming update while improvements are made.

Microsoft patch gives domain-joined Windows PCs trust issues

Microsoft acknowledged a significant issue affecting Windows 11 versions 24H2, 25H2, and 26H1 related to Active Directory domain logins as of September 16. This issue stems from changes made to Machine Identity Isolation in the September 2026 security update (KB5124008), which may cause Credential Guard-protected machine accounts to lose their secure channel with an on-premises Active Directory domain, preventing users from signing in with valid domain credentials. The update activates Machine Identity Isolation but does not enforce it immediately, and it is only compatible with environments linked to domain controllers operating at the Windows Server 2025 Domain Functional Level (DFL) or higher. Microsoft advised that devices not connected to Windows Server 2025 domain controllers will need to disable Machine Identity Isolation. A workaround involves disabling the feature through Intune, Group Policy, or the Windows Registry, followed by a device restart and repairing the secure channel using the Test-ComputerSecureChannel PowerShell command. Microsoft plans to address this issue in a future update by temporarily halting Machine Identity Isolation enforcement while enhancements are made.

AI Is Changing Antivirus From File Matching to Behaviour-Based Malware Detection

Artificial intelligence is transforming malware detection by moving away from traditional file signature reliance to analyzing program actions. Antivirus software previously used signatures to identify known threats, but the rapid emergence of over 450,000 new malware samples daily complicates this method. Attackers now employ techniques like repacking and encryption to evade detection, prompting the need for machine-learning and behavioral techniques for better protection. Modern detection systems assess multiple characteristics of executable files, including their behavior, to identify potential threats, even if they lack recognized signatures. Microsoft's Project Ire exemplifies advanced detection capabilities, functioning as an automated malware analyst that evaluates unknown binaries based on their behavior. Additionally, modern endpoint-security products leverage cloud systems to analyze data from multiple devices, enhancing threat detection through shared intelligence. However, AI detection can still produce false positives and is susceptible to manipulation by attackers. Therefore, effective security systems require a combination of traditional measures, behavioral monitoring, machine learning, and human analysis to navigate complex threats.

New Android Ransomware Records Screens, Steals OTPs and Secretly Takes Photos of Victims

A newly identified malware threat in the Android ecosystem, named Mantax Otax, combines ransomware with espionage capabilities. It targets users who install applications from untrustworthy sources, often through messaging apps or phishing attempts. The malware is linked to Indonesian cybercriminals and can steal sensitive information such as SMS one-time passwords, chat histories, and lock-screen PINs, facilitating account takeovers. Mantax Otax requests device-administrator rights and seeks access to SMS messages, contacts, and media files. It encrypts files on devices running Android 9 and earlier using AES encryption and demands a ransom for recovery. Although the impact is reduced on Android 10 and later due to Scoped Storage, the malware still poses significant surveillance risks. The malware collects extensive sensitive data, including contacts, call logs, and location data, and targets multi-factor authentication codes. It uses a deceptive system-lock overlay to capture PINs and has introduced features like WebSocket communications and disruptive pop-ups in its second iteration. Users are advised to be cautious when installing applications, avoid unsolicited APKs, and reject permissions that do not align with an app's purpose. In case of suspicious activity, users should disconnect from networks and seek help before entering sensitive information. Organizations should monitor for signs of this malware on managed devices.
