How to Remove a Keylogger: 12 Steps, 60 Min [2026]

A keylogger captures every keystroke made on a device and sends that information to an external source. In 2025, infostealer malware, including keyloggers, resulted in the theft of 642.4 million credentials from 13.2 million infections globally. In Australia, approximately 30,000 banking passwords were compromised between 2021 and 2025 due to this malware. The Australian Cyber Security Centre reported over 42,500 calls related to credential theft in one year, a 16% increase. Four main malware families dominate the landscape, with LummaC2 accounting for nearly 60% of credentials linked to infostealers in 2026. Keyloggers can be detected through signs such as typing lag, unexpected antivirus notifications, new browser extensions, and unexplained spikes in outbound data usage. Detection and removal steps include checking running processes, auditing startup programs, reviewing installed programs, running antivirus scans, and resetting passwords from a clean device. Keyloggers can infiltrate systems via phishing emails, malicious attachments, or compromised software downloads. Mobile devices can also be targeted by keyloggers disguised as legitimate apps.

One Click, Full Phone Access: Malicious Android Apps Raise Financial Fraud Risk

Malicious Android applications are being promoted through social media advertisements, particularly on platforms like Instagram and Facebook, posing significant risks to users. The Indian Cyber Crime Coordination Centre (I4C) has warned about deceptive apps advertised under names such as Night Play, Reloop, Kyss, Vimo, Rivo, Nezo, and Vixa, which often redirect users to pornographic websites to download APK files. These applications can exploit sensitive device permissions, leading to malware infections, unauthorized financial transactions, and various forms of cyber fraud. Users may be tricked into granting accessibility permissions that allow the malware to operate in the background and potentially install a VPN, rerouting internet traffic through servers controlled by attackers. Cybersecurity experts advise users to verify the legitimacy of applications before installation and to be cautious of permissions requested by unknown apps.

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.

How to sideload apps onto Android Auto

Android Auto was designed for simplicity, but users want more functionality like streaming YouTube or screen mirroring. Sideloading allows users to install unapproved apps, unlocking additional features, though it poses risks to security, reliability, and safety. To sideload apps, users must enable Developer Mode on their phone and Android Auto, then install the Android Auto Apps Downloader (AAAD) and explore open-source apps like CarStream and AAMirror. Risks of sideloading include safety concerns with video streaming while driving and increased exposure to malware, as sideloaded apps bypass Google’s security checks. Google plans to introduce new verification requirements for developers starting in late 2026 to mitigate these risks. Most drivers find the standard Android Auto experience sufficient, and sideloading should be approached cautiously.

Norton excels in real-time protection, lab test scores, and features such as a firewall and parental controls, while Malwarebytes is effective at removing existing infections and has a free tier.

ValleyRAT Backdoor Hides in Signed Adware That Users Add to Antivirus Exclusions

Silver Fox is linked to the distribution of a backdoor malware called ValleyRAT, disguised as the legitimate QN Wallpaper adware application. Once installed, ValleyRAT provides complete control over the compromised machine. The malware uses DLL sideloading to operate under the guise of a legitimate process, bypassing security measures. It disables Windows Defender and adds itself to autorun entries, and can mark its process as critical, causing system crashes if terminated. Kaspersky has identified specific indicators of compromise (IoCs) including hashes, command-and-control servers, and associated domains. In 2026, Kaspersky recorded over 100,000 detections of ValleyRAT affecting more than 1,500 unique users, mainly in China and India.
