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.

RatHat Android Malware Abuses ADB to Retain Shell Access After Uninstall

Cybersecurity experts have identified a new Android malware named RatHat, believed to be operated by Chinese threat actors. RatHat is distributed primarily through smishing and malvertising campaigns, leading users to deceptive download portals. It employs an automated multi-stage infection process and exploits Accessibility features along with a local ADB self-pairing mechanism to escape the Android application sandbox. The malware uses various anti-analysis techniques, including container tampering, manifest bombs, DEX bytecode poisoning, and dual string-encryption. RatHat's architecture consists of a malicious Android application, a Go agent, and an FRP reverse-proxy client, which together enable it to gain critical system permissions and perform various malicious activities such as credential capturing, screen recording, and SMS interception. Even if uninstalled, the malware retains shell access to the device, allowing attackers to reinstall it. RatHat can serialize the device's Accessibility tree to XML and communicate with a Generative AI assistant for tasks like screen coordinate determination and text extraction. The Go Agent, masquerading as a native library, exploits shell access to execute commands and establish a persistent connection to a command-and-control server via the FRP client. The C2 server can issue extensive commands to collect sensitive information, including SMS messages, credentials, files, and keystrokes, and RatHat also features a hardware-level keylogger.

Fake Software Installers Disable Windows Update and Weaken Microsoft Defender

An active malware campaign is using counterfeit software-download websites to distribute malicious installers, primarily targeting users seeking popular software. This campaign has significantly affected China-based operations of multinational corporations and Chinese-speaking users. The malware, once executed, can establish persistence, undermine security measures, and communicate with attacker-controlled infrastructure. Victims span various sectors, including healthcare, manufacturing, gaming, technology, logistics, government, and education. Microsoft associates this campaign with a Chinese threat cluster called Silver Fox, known for using spoofed vendor download pages to spread Gh0st RAT and ValleyRAT. The malicious websites are hosted on .com.cn and .hl.cn domains, featuring Chinese-language content. The downloaded files are dynamically generated, and upon execution, they deploy a wrapper installer that initiates the malware payload. The malware achieves persistence through scheduled tasks and interferes with Windows Update services. The campaign establishes command-and-control communication over non-standard ports, with two identified domains linked to the activity. Microsoft Defender has detected the threat and initiated containment procedures. Kaspersky reported a related malicious installer exploiting a legitimate adware application to execute a backdoor, which captures keystrokes and clipboard contents. ValleyRAT, a sophisticated implant, can collect system information, reboot the computer, capture screenshots, and transmit logs. The attackers are motivated by cyber espionage and financial gain, targeting organizations globally. A subgroup within GoldenEyeDog, known as CuboidalCanine, has also been linked to the use of ValleyRAT, particularly in the gambling industry. In June 2026, Chinese authorities addressed cybercrime cases involving a new variant of the Silver Fox trojan.
