Google warns millions of android users as virus spreads via WhatsApp, Instagram, Facebook, YouTube and more Apps; How to stay safe

Google has issued a warning to Android users about a dangerous malware called Arsink Malware, which is a Remote Access Trojan (RAT) capable of stealing personal information and taking control of infected devices. It spreads through apps that appear legitimate, often masquerading as "Mod" or "Premium" versions of popular applications. Arsink malware typically infiltrates devices via Telegram channels, Discord posts, third-party websites, and suspicious download links. Google has confirmed that no versions of Arsink are available on the Play Store and that devices with Google Play Protect enabled are automatically safeguarded against such threats. Google is also working with researchers to dismantle the infrastructure associated with this malware. To stay safe, users are advised to download apps only from the official Google Play Store, avoid 'Mod' or 'Premium' versions of apps, refrain from clicking on suspicious links, carefully check app permissions, keep Google Play Protect enabled, and regularly update their devices for security patches.

Android Malware FvncBot, SeedSnatcher, and ClayRat Gain Stronger Data Theft Features

Cybersecurity researchers have identified two new families of Android malware, FvncBot and SeedSnatcher, as well as an upgraded version of ClayRat. FvncBot is designed to target mobile banking users in Poland, masquerading as a security application from mBank. It is built from scratch and includes features such as keylogging, web-inject attacks, screen streaming, and hidden virtual network computing (HVNC). It uses a crypting service called apk0day and communicates with a remote server at naleymilva.it.com. FvncBot requests accessibility permissions to operate with elevated privileges and can perform various malicious activities, including exfiltrating data and delivering overlays on targeted applications. SeedSnatcher is disguised as a cryptocurrency wallet app called Coin and is distributed via Telegram. It focuses on stealing cryptocurrency wallet seed phrases and can intercept SMS messages to capture two-factor authentication codes. It employs techniques like dynamic class loading and WebView content injection to evade detection and initially requests minimal permissions before escalating its access. The upgraded ClayRat malware now exploits accessibility services and default SMS permissions, allowing it to record keystrokes, capture screen content, and present deceptive overlays. It has been distributed through fraudulent phishing domains and dropper apps that impersonate legitimate services. The enhanced capabilities of ClayRat enable complete device takeovers and persistent overlays, making it a more significant threat than its previous version.

Malicious Rust Crate Delivers OS-Specific Malware to Web3 Developer Systems

A malicious Rust package named "evm-units," uploaded by a user called "ablerust" to crates.io in mid-April 2025, poses a significant threat to developers on Windows, macOS, and Linux. It has over 7,000 downloads and is designed to execute its payload stealthily, depending on the victim's operating system and the presence of Qihoo 360 antivirus. The package disguises itself as a function that returns the Ethereum version number and can detect Qihoo 360 antivirus software. It downloads and executes different payloads based on the operating system: a script for Linux, a file for macOS, and a PowerShell script for Windows. If the antivirus is not detected, it creates a Visual Basic Script wrapper to run a hidden PowerShell script. The package targets the Web3 community, particularly developers, and is linked to the widely used "uniswap-utils" package. Both "evm-units" and "uniswap-utils" have been removed from the repository.

Android malware Albiriox abuses 400+ financial apps in on-device fraud and screen manipulation attacks

A new malware-as-a-service (MaaS) called Albiriox has emerged, targeting banking and cryptocurrency applications, particularly focusing on Austrian users. It is marketed on the dark web and employs deceptive tactics, such as mimicking legitimate businesses and creating fake landing pages and app listings on the Google Play Store. Victims are tricked into providing their phone numbers, leading to the delivery of a malicious APK file via SMS or WhatsApp. This APK acts as a dropper, designed to bypass detection methods and requests permissions under the guise of a “software update” to download the actual malicious payload. Once installed, it can take control of the device or function as an infostealer, extracting sensitive information like phone numbers and passwords, which is sent to a Telegram channel. Cleafy researchers suggest that the Albiriox campaign is linked to Russian cyber actors based on their activities on cybercrime forums and communication style.
