RistOS – The app-less Android whose brain stays at home

The narrative describes a Google Pixel smartphone using RistOS, a minimalist firmware designed for the Pixel 10a. Upon activation, the interface displays only the time, a microphone button, and a text input line. RistOS replaces the traditional Android launcher with a voice assistant and organizes phone functionalities in a side menu with seven entries: Phone, Messages, Camera, Gallery, Offline Maps (Organic Maps), Flashlight, and Settings. There is no app store, browser, or Google account, emphasizing simplicity. RistOS is built on GrapheneOS but is not affiliated with it or Google. It is only compatible with the Pixel 10a, priced at €389. The microphone button does not activate listening by default; users must configure settings to connect to a Rist backend for audio command processing. User data is centralized on a server, and the installation process erases existing data. The system does not support contacting emergency services, and alternatives like /e/OS are suggested for those wanting to avoid Google's ecosystem without server setup.

Gigabud Creates Android Work Profiles to Hide From Banking App Malware Checks

The Gigabud banking trojan installs a secondary Android application called Vwork, which creates a work profile on compromised devices to evade detection from banking app security measures. This work profile separates its contents from the personal space of the device, allowing fraudulent transactions without triggering alerts. Group-IB confirmed this operational chain in Indonesia, where Gigabud has been active since 2022 and is linked to the GoldFactory group, which uses deceptive tactics to distribute the trojan. Vwork simplifies the creation of a work profile and communicates with an external server for authorization before cloning apps. The report indicates that Vwork has been detected in various countries, while approximately 1,469 devices and 1,281 logins were compromised in Indonesia, leading to estimated losses of around ,000,000. Users can check for a work profile in their phone's settings and are advised to download apps only from official stores and to deny unnecessary Accessibility access.

Comma Compliance Open-Sources the Android App That Archives Employee Text Messages

Comma Compliance released the source code for its Android capture component on September 10, 2026, allowing corporate IT and security teams to inspect the software that captures employee text messages for compliance archiving. The source code is available on GitHub under the MIT license. The capture mechanism reads messages stored in the phone's default messaging app, encrypts them, and sends them to the customer's Comma backend without intercepting messages in transit. A persistent notification appears on the phone when archiving is active, indicating the organization responsible for the archiving. Comma previously open-sourced its WhatsApp and Signal capture connectors in 2025.

8 Antivirus (Endpoint Protection) Software for Business: Our Top Picks by Use Case (2026)

If you hold Microsoft 365 E5, you have access to Microsoft Defender for Endpoint, which provides enterprise-grade endpoint protection at no additional cost. For organizations without a dedicated security specialist, Sophos is recommended for its user-friendly platform. CrowdStrike is suggested for those with a mature Security Operations Center (SOC) and sufficient budget. Other options include SentinelOne for mid-sized organizations needing automation, ESET for older hardware and virtual desktops, Avast Business for very small businesses, VIPRE for budget-conscious mixed estates, and Expel for tool-agnostic managed detection and response. Antivirus and EDR are now unified under a single agent, and organizations should inquire about update staging processes to avoid issues like those experienced in July 2024 with a major vendor's faulty content update. Independent tests from organizations like AV-Comparatives and AV-TEST are crucial for evaluating protection rates and false positives. Linux servers require attention as they are often targeted by ransomware. When deploying endpoint protection, avoid running two real-time agents simultaneously, activate prevention features promptly, and test deployments on critical applications first. Organizations should confirm their Microsoft licensing covers necessary features and ensure there is a plan for responding to alerts. Common pitfalls include neglecting identity management and failing to test response workflows before incidents occur.

CVE-2026-85880 and CVE-2026-81963: Microsoft Patches Two Actively Exploited Windows Zero-Days

Microsoft's Patch Tuesday on September 8, 2026, addressed two critical Windows privilege escalation vulnerabilities: CVE-2026-85880 and CVE-2026-81963, both with a CVSS score of 7.8. CVE-2026-85880 is a heap-based buffer overflow in the Windows Advanced Local Procedure Call (ALPC), allowing attackers with low-privilege local access to escalate privileges to SYSTEM. CVE-2026-81963 involves improper link resolution in the Windows Update Stack, enabling similar privilege escalation. Both vulnerabilities require no user interaction and have been actively exploited prior to the patch release. CISA added them to its Known Exploited Vulnerabilities catalog on September 8, 2026, with a remediation deadline of September 22 for U.S. federal agencies. CVE-2026-85880 affects various Windows 10 and Server versions but excludes Windows 11 and Windows Server 2025. CVE-2026-81963 impacts newer Windows platforms, including Windows 11 and Windows Server 2025. Microsoft released security updates for both vulnerabilities on September 8, 2026, and organizations are advised to prioritize these updates. Security teams should monitor for signs of privilege escalation and unusual SYSTEM-level activities related to these vulnerabilities.

Gigabud Uses Android App Cloning to Evade Fraud Detection

The Gigabud Android banking trojan can clone banking applications into a separate Android work profile, allowing fraudsters to bypass malware alerts during transactions. Research by Group-IB, released on September 9, indicates that Gigabud is used with Vwork, a modified app for cloning, attributed to the GoldFactory group. The infection has been confirmed in Indonesia but targets 11 countries, including Brazil, Colombia, Egypt, Mexico, Thailand, and Turkiye. Vwork uses Android's Work Profile feature to isolate cloned apps, making them less detectable. This allows operators to install malware, clone banking apps, and execute transactions without raising alarms. During fraud, fake login screens capture credentials, and an invisible overlay collects lock screen codes. From February to July 2026, 1,469 devices were compromised in Indonesia, with financial losses nearing 0,939. Gigabud spreads through phishing and social media, requesting permissions to control devices. Group-IB identified six behavioral signals for banks to monitor as indicators of high-risk sessions. Recommendations include device binding and downloading apps only from official stores.

Microsoft’s Two-Track Patch Tuesday: Cloud Identity Flaws Fixed Before Disclosure, Windows Still Catching Up

The September 2026 security cycle revealed a bifurcated approach to vulnerability management by Microsoft, focusing on cloud-side identity services with silent mitigations and traditional Patch Tuesday updates for on-premises Windows infrastructure. On September 3, Microsoft addressed nine cloud-side vulnerabilities, including two with a CVSS score of 10.0: CVE-2026-83711 (Azure AD B2C elevation of privilege) and CVE-2026-70352 (Azure AI Language Authoring missing authentication). Additionally, CVE-2026-83941 (Entra ID elevation of privilege, rated 9.9) and CVE-2026-80098 (Copilot Studio cryptographic flaw) were noted. On September 8, the Patch Tuesday update addressed 70 CVEs, including critical issues in the on-premises stack, such as CVE-2026-83939 (Windows Secure Kernel Mode elevation of privilege). CVE-2026-69414 (ShieldBreak), an elevation of privilege vulnerability in the Defender Malware Protection Engine, was patched out-of-band on September 3 after being publicly exposed for three weeks. Microsoft is shifting its Self-Service Password Reset (SSPR) enforcement to default to passkeys as of September 7, with plans to phase out SMS and voice-based authentication by February 2027. This aims to enhance security by moving away from legacy credentials.
