Trojanized Alpine Quest app geolocates Russian soldiers

Russian soldiers are facing a digital threat from a modified Android application, Alpine Quest, which has been tampered with to track their locations and extract sensitive information. The malware, known as Android.Spy.1292.origin, was embedded in an older version of the app and distributed as a free upgrade to Alpine Quest Pro via a fraudulent Telegram channel. Once installed, the trojan collects various types of information, including geolocation, downloaded files, phone numbers, and app versions, and can download additional modules to exfiltrate specific files. Additionally, researchers at Kaspersky discovered a backdoor hidden in counterfeit software updates for ViPNet, a secure networking suite. The malware, disguised as msinfo32.exe, connects to a command-and-control server to steal files and deploy more malicious components. On the Ukrainian side, Russian operatives are conducting a phishing campaign targeting Ukrainian officials and allies, using social engineering tactics to hijack Microsoft 365 accounts. Attackers contact victims via messaging apps, invite them to video calls, and trick them into providing OAuth codes, granting access to their accounts.

PJobRAT Android RAT as Dating & Instant Messaging Apps Attacking Military Personnel

PJobRAT is an Android Remote Access Trojan (RAT) that re-emerged in 2023 with improved capabilities and a refined targeting strategy, previously known for attacking Indian military personnel in 2021. It is now targeting users in Taiwan through social engineering tactics, disguising itself as legitimate dating and messaging apps. The malware is distributed via compromised WordPress sites hosting fake applications like “SaangalLite” and “CChat.” The infection footprint is small, indicating highly targeted attacks rather than widespread campaigns. PJobRAT retains its core functionality of exfiltrating sensitive information, including SMS messages, contacts, and media files, while enhancing command execution capabilities. Upon installation, the malicious apps request extensive permissions to operate continuously in the background. The malware uses a dual-channel communication infrastructure, with Firebase Cloud Messaging (FCM) as the primary command channel and a secondary HTTP-based channel for data exfiltration to a command-and-control server. The campaign appears to have concluded, but the evolution of PJobRAT highlights the ongoing threat of sophisticated mobile malware targeting high-value individuals.

Invisible Windows Rootkit Hides Dangerous Files Using This Prefix

Obscure#Bat is a malware campaign targeting Windows users that uses obfuscated batch scripts to deploy a user-mode rootkit, which can hide its activities from standard security measures. It stores hidden scripts in the Windows Registry and can conceal files, registry entries, and running processes through application programming interface hooking. The malware can embed itself within legitimate Windows processes, making it undetectable by conventional security methods, and is capable of deleting evidence of its activity. Attackers use social engineering tactics, such as fake CAPTCHA tests and legitimate software tools, to lure victims into executing the malicious batch file. The rootkit obscures files, processes, or registry keys that begin with the “$nya-” prefix and is identified as an open-source ring-3 rootkit known as r77. It avoids kernel modifications and relies on registry and scheduled tasks for persistence, allowing it to evade detection by traditional kernel-based security tools. Windows users are advised to be cautious of social engineering tactics and to inspect batch files in a text editor before execution.
