Android Malware Caught by Teaching AI to Read Apps as Pictures

A research team from Turkey, led by Erdal Başaran and Ömer Okucu of Ağrı İbrahim Çeçen University, along with Yusuf Alaca from Hitit University, has developed an innovative detection framework for Android malware that utilizes a visual approach. This framework transforms key features of Android applications into images, allowing a Vision Transformer to differentiate between benign software and malware. The researchers created two types of images from static and dynamic analysis features: a conventional 2D grayscale image and a QR code image. Separate Vision Transformer models were trained on each image type, and spatial pooling features were extracted from deeper layers to create a comprehensive representation of application behavior. To refine the fused feature vector, Recursive Feature Elimination (RFE) was employed, enhancing classification clarity and reducing computational load. The final classification utilized a majority-voting ensemble strategy, achieving a detection accuracy of 98.72 percent, surpassing standalone models. The study demonstrates that the multimodal system outperforms individual grayscale or QR code pathways. The dataset used is publicly available, promoting reproducibility. The framework's reliance on static and dynamic analysis features allows it to adapt to new threats, and the novel QR code representation offers distinctive visual signatures of malicious behavior. However, challenges remain regarding feature extraction quality and computational demands.

VPN threat protection vs. dedicated antivirus: Are VPNs really enough?

Many VPN providers are now offering additional security features such as malware detection, malicious link checkers, and ad blockers, alongside their primary function of encrypting internet traffic. Notable VPNs like NordVPN and Surfshark have integrated real-time malware protection, with NordVPN becoming the first VPN to receive certification as a reliable anti-phishing tool in 2024. Surfshark's Surfshark One package offers comprehensive real-time protection from viruses and malware. Other VPNs, such as Avira and CyberGhost, utilize shared infrastructures for antivirus capabilities, which can lead to delays in updates and inconsistent platform support. Microsoft Defender has improved significantly, blocking 95.5% of live threats according to AV-Comparatives, while Apple employs multiple defenses in macOS, including Gatekeeper and XProtect, to manage malware threats. Avast Free Antivirus has achieved a perfect 100% block rate in recent testing but comes with limitations compared to paid antivirus suites like Norton 360 Deluxe and Bitdefender Total Security, which offer additional features such as password managers and identity monitoring. A layered approach to digital security, combining a VPN, free antivirus, and built-in OS-level security, is recommended for effective protection. Relying solely on one layer leaves potential gaps, as a VPN cannot detect existing malware, and free antivirus solutions may lack advanced features. Users managing sensitive data or frequent financial transactions should consider investing in premium antivirus suites for enhanced security.

Microsoft warns fake CAPTCHA tests are hijacking Windows PCs

Microsoft has warned Windows users about a cyber threat that disguises itself as a CAPTCHA test, where cybercriminals use fraudulent verification pages to trick users into executing commands that can install malware. This tactic involves users being directed to a compromised website that presents a fake verification window, prompting them to copy text and execute it in the Windows Run dialog. This method allows attackers to bypass antivirus software by pre-loading malicious scripts disguised as harmless images in the browser's cache. Once activated, the malware collects system information, steals data, and maintains long-term control over the system. Microsoft recommends using robust security software and being aware that no legitimate service will ask users to copy and paste commands into system dialogs.

RatHat Android Malware Console Uses Gemini to Identify Higher-Value Victims

The operators behind RatHat have created an advanced Android banking trojan that allows control of infected devices through a web console. Since April 2026, nearly 100 instances of this console have been identified, indicating a malware-as-a-service model. The console collects sensitive data from compromised phones, including text messages and passwords. It uses Google's Gemini AI to assess victims' bank balances, categorizing them into high-value and mid-value segments, but does not facilitate financial transactions. The malware has remained largely unchanged since late 2025, but the console has seen significant updates, leading to three new versions: BlackCat Remote Control Management, Panda Workshop V5, and V6. These versions serve as both control interfaces and build tools for creating and distributing malware. The latest version includes templates for deceptive download pages. RatHat infiltrates devices via text messages and online ads, requesting Accessibility access to read screens and simulate user interactions. This access allows the malware to activate wireless debugging and connect to the Android Debug Bridge (ADB), giving operators elevated privileges to execute commands. A Go program can be deployed to maintain control, even after the app is uninstalled. Cleafy has tracked console deployments through web code analysis, noting that many IP addresses originate from a Singapore-registered network. The initial console version allowed operators to choose AI providers, but the latest exclusively uses Gemini. RatHat also utilizes Gemini on infected devices to determine tap locations based on screen layouts. Cleafy has compiled indicators related to the consoles' command-and-control servers, download links, and malware samples, including specific domains, IP addresses, and MD5 hashes. The consoles often use web addresses starting with "admin." and inexpensive top-level domains. Security tools are advised to monitor processes running under the shell user on affected devices.

Cisco Talos Discloses Autonomous Windows Malware: Four AI Models Direct Each Attack

Cisco Talos has disclosed a new Windows implant called CLOSEDQUORUM, which operates without human operators by using four commercial large language models (LLMs) to autonomously decide on actions after deployment. The implant is a 16.4-megabyte executable that conducts reconnaissance on the target system and sends structured prompts to the LLMs, which respond with one of four actions: steal, inject, persist, or move. When the "steal" action is chosen, it simultaneously attacks three credential stores, extracting Windows credentials, browser passwords, and cryptocurrency wallet data. The "inject" action uses either Early Bird APC injection or process hollowing based on model recommendations. For persistence, it employs three overlapping mechanisms, including a Registry Run key, a scheduled task, and a WMI event subscription. To evade detection, CLOSEDQUORUM suppresses ETW telemetry and introduces delays before executing actions. It circumvents traditional command-and-control structures by calling legitimate API endpoints, making blocking these domains impractical. Talos introduced the CAIRN toolkit for detecting AI-integrated malware, which operates on metadata and employs rule-based detection. Unlike previous AI-assisted malware, CLOSEDQUORUM automates decision-making processes entirely, highlighting a significant evolution in malware capabilities. Security teams are advised to focus on behavioral detection strategies and utilize the YARA rule and CAIRN toolkit for identifying this threat.

Cisco Talos Discloses Autonomous Windows Malware: Four AI Models Direct Each Attack

Cisco Talos has disclosed a Windows implant called CLOSEDQUORUM, which automates cyberattack execution using four advanced commercial large language models: DeepSeek, Qwen, Mistral, and Google Gemini. The implant is a 16.4-megabyte executable that conducts reconnaissance on the system and formats the gathered data into prompts for the AI models. Each model votes on one of four actions: steal, inject, persist, or move, with the action receiving the most votes being executed. When stealing, CLOSEDQUORUM targets three credential stores, dumping LSASS memory and retrieving saved passwords from browsers and cryptocurrency wallets. The stolen data is encrypted and sent to the operator via Discord. For injection, it uses Early Bird APC injection or process hollowing based on model responses. The persist action creates three mechanisms for longevity, including a Registry Run key, a scheduled task, and a WMI event subscription. CLOSEDQUORUM evades detection by suppressing ETW telemetry and delaying activity to avoid sandbox analyses. It connects to legitimate API endpoints, making blocking ineffective without disrupting enterprise applications. Talos recommends behavioral combination detection strategies and the use of a YARA rule for detection. The CAIRN toolkit has been introduced to detect AI-integrated malware without executing binaries. Unlike previous AI-assisted malware, CLOSEDQUORUM removes human decision-making from the attack process.
