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.

Hackers abuse FTP server banners to deliver new Windows malware

Threat actors are exploiting FTP banners to conceal commands for deploying two undocumented remote access trojans (RATs), E4del and PINHOLE. This method was first observed by MalwareHunterTeam in July 2026, using shortcut files (.LNK) and FTP server banners as dead-drop resolvers to retrieve malicious commands. SOCRadar confirmed that this technique has been weaponized since early July 2026 and remains active, with new infrastructure identified as recently as August 2026. The attacks typically start with a ZIP archive leading to an LNK-based infection chain, likely initiated through phishing tactics. E4del is a Node.js-based RAT disguised within a digitally signed Electron application mimicking Discord, capable of executing commands, capturing screenshots, streaming desktops, and downloading additional payloads. It also includes a module for privilege escalation. PINHOLE retrieves its command and control configuration from Pinterest and SurveyMonkey, designed to leave a minimal footprint and employing shellcode fluctuation. It supports 14 commands, including file management and credential theft, but had only recorded 11 execution events at the time of analysis. SOCRadar notes that while using FTP banners is a novel approach, it is less stealthy than traditional web-based dead-drop resolvers. They provide indicators of compromise to help identify malicious infrastructure and infected machines.

Best Ransomware Protection 2026: Tested and Ranked

Ransomware protection is best approached as a layered strategy rather than relying on a single solution. The effectiveness of software is significantly enhanced by maintaining a well-managed backup that is disconnected during an attack. Five tools were evaluated based on their default settings, focusing on behavioral detection, protected folders, file rollback, and real-time protection. 1. Norton 360: Rated as the best overall ransomware protection, it offers comprehensive features including behavioral monitoring, protected folders with dual alert modes, and 50 GB of cloud backup within a single subscription. It has a perfect score in advanced threat assessments. 2. Bitdefender: Recognized for its file rollback and remediation capabilities, it provides an effective "undo" feature that restores files, although this feature is turned off by default. 3. Avast One Free: The best free ransomware protection option, it includes a dedicated shield on the free Windows tier and has achieved a perfect score in advanced threat assessments. 4. NordVPN Threat Protection Pro: Best for blocking the delivery route of ransomware, it prevents downloads before encryption starts but cannot stop the process once it has begun. 5. McAfee: Best for protecting multiple devices simultaneously, it offers unlimited device coverage on most plans with integrated ransomware defense in its scanning engine. Modern ransomware protection software has shifted from signature matching to focusing on monitoring the behavior of processes interacting with files. The four essential layers of protection include behavioral monitoring, protected folders, automatic file rollback, and backup. Most users do not need a separate anti-ransomware product, as these features are typically included in main antivirus suites, with the key consideration being whether these features are activated. The rankings of the tools were based on whether the ransomware protection layer is enabled by default, the extent of file recovery when intervention occurs, and the frequency of false positives during normal use. - Norton 360: Best overall, with protection enabled by default and a perfect score in advanced threat testing. - Bitdefender: Best for file rollback, but the rollback feature is disabled by default. - Avast One Free: Best free option, with a perfect score in advanced threat assessments but lacks rollback capabilities. - NordVPN Threat Protection Pro: Effective at blocking malware downloads but does not provide rollback or backup features. - McAfee: Suitable for families with multiple devices, offering automatic backup of flagged files but lacks user-configurable protected folder options. The effectiveness of ransomware protection tools is primarily assessed through behavioral responses rather than library matching. Backup remains a critical layer of defense, functioning even when other layers fail.

New Android Malware Spotted Infecting Cars Via Software Updates

A new strain of Android malware has emerged, targeting automotive head units responsible for infotainment, connectivity, and navigation in vehicles. Discovered by Kaspersky in June, this is the first documented instance of malware affecting car head units, specifically within the firmware updaters of Android-based software developed by DoFun, a Hong Kong company. The malware, disguised as an application called JarService, infiltrates devices without user awareness. It is delivered through a legitimate system application called TWCore, which collects analytics and updates software. The malware aims to convert the head unit into a botnet, equipped with commands to download and execute code and display advertisements, potentially for online ad fraud. Kaspersky notified DoFun, which addressed the vulnerabilities, and noted similarities between this malware and a previous threat called BadBox, which affected various Android devices.

Hackers Are Using a Fake Roblox Cheat To Access Your Webcam and Steal Data

Roblox is facing privacy concerns due to spyware disguised as an "undetected" version of the Xeno Roblox cheat tool. This malware can access screens, record keystrokes, and activate webcams, allowing attackers to execute remote commands. The infection begins when users download a file resembling a legitimate Xeno installation, often shared on platforms like Discord. The malware, previously known as Powercat, has evolved and operates in three stages: 1. The user executes a file named Xeno.exe, which checks for Java and extracts it if necessary. 2. The malware runs a JAR file disguised as decompiler.exe, performing checks to avoid detection. 3. It masquerades as a legitimate Windows DLL file, logging activities and attempting to escalate privileges. If successful, the malware can control the victim's system, access webcams, log keystrokes, and steal sensitive information, including cryptocurrency wallet credentials. To protect against this spyware, users are advised to avoid unofficial cheats, use antivirus software, refrain from clicking unsolicited links, enable two-factor authentication, inspect User Account Control prompts, and consider identity theft protection services.

The Truth About Android Antivirus Apps in 2026

Most Android users consider third-party antivirus apps unnecessary due to the robust built-in security features of modern Android smartphones. However, Android devices are still vulnerable to viruses, malware, and security breaches, with a 2025 Gen threat report indicating a tripling of malicious push notifications and an increase in spyware issues. Google Play Protect blocked 27 million malicious apps in 2025 and conducts scans to manage security. Android employs sandboxing, regular security updates, and an opt-in permissions system to protect users. Upcoming features include phone call spoofing protection and enhanced live threat detection capabilities. Social engineering tactics, such as phishing and fake tech support calls, pose significant risks that antivirus software cannot address. Connecting to open Wi-Fi networks can expose devices to risks, and malicious push notifications can mislead users. Third-party antivirus apps may be beneficial in high-risk scenarios, such as public Wi-Fi networks or when sideloading apps, providing an additional layer of protection.
