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.

8 Antivirus Software for Mac: Our Top Picks by Use Case (2026)

Apple provides built-in security features for macOS, including XProtect, Gatekeeper, and automatic malware removal, which contribute to the safety of Macs. However, these protections do not effectively address threats like infostealers, phishing, and adware. For enhanced security, third-party antivirus solutions are recommended. Bitdefender is noted for its strong detection rates and minimal system impact, making it suitable for most users. Intego specializes in Mac-specific threats and is ideal for users focused solely on Apple products. ESET and Trend Micro are recommended for businesses needing centralized management. F-Secure is recognized for its privacy-focused approach, while Norton offers a comprehensive suite of security features. AVG provides free real-time protection suitable for low-risk personal use, but may not be adequate for business needs. CleanMyMac is a maintenance tool rather than a traditional antivirus, focusing on system cleanup and optimization. Users should avoid running multiple real-time scanners simultaneously and ensure they purchase appropriate licenses for business use. It's important to evaluate the necessity of additional features and consider long-term pricing when selecting antivirus software.

Best Android Antivirus Apps 2026: Tested and Ranked

Bitdefender Mobile Security is rated as the best antivirus app for Android in 2026, achieving a 100% detection rate, 0.5% battery drain, and unobtrusive operation. The evaluation compared five antivirus applications on a Galaxy S26 Ultra, assessing detection rates, battery drain, scan speed, and permissions. Other notable antivirus apps include Norton 360 for Mobile, which is recognized for its features; Avast Mobile Security, known for its free version; McAfee Mobile Security, which excels in scam call and text filtering; and NordVPN Threat Protection, praised for web and Wi-Fi security. Most users may not need an antivirus app due to built-in protections like Google Play Protect, which automatically scans apps. However, specific scenarios warrant the installation of an antivirus app, such as sideloading apps, receiving scam texts and calls, assisting relatives, conducting banking and shopping on mobile, and using public Wi-Fi. The top five antivirus apps tested are: 1. Bitdefender Mobile Security: 100% detection, 0.5% battery drain, 31-second scan time. 2. Norton 360 for Mobile: 99.9% detection, 0.9% battery drain, 24-second scan time. 3. Avast Mobile Security: 99.9% detection, 0.7% battery drain, 26-second scan time. 4.

Battery consumption varied, with NordVPN being the lightest and McAfee the heaviest. Permissions requested by each app also varied significantly, with Bitdefender requiring the most extensive permissions. Users are advised to check for legitimate antivirus apps by verifying the developer, installation count, update history, lab participation, and permission requests. Free antivirus apps like Avast and AVG offer effective protection but may lack some features of paid versions. Users should be cautious of fake security apps that mimic legitimate ones. If malware is suspected, users can run scans with Google Play Protect or other anti-malware apps and follow specific steps to remove malware if detected.
