Recent research from cybersecurity firm Sophos has identified the use of PJobRAT malware targeting users in Taiwan through instant messaging applications SangaalLite and CChat, which mimic legitimate platforms. These malicious apps were available for download on various WordPress sites, now taken offline. PJobRAT, an Android remote access trojan first identified in 2019, has been used to steal SMS messages, contacts, device information, documents, and media files. The recent cyber-espionage initiative lasted nearly two years, affecting a limited number of users, indicating a targeted approach by the attackers. The latest version of PJobRAT lacks the ability to steal WhatsApp messages but allows attackers greater control over infected devices. The distribution method for these apps remains unclear, but previous campaigns involved third-party app stores and phishing pages. Upon installation, the apps request extensive permissions and provide basic chat functionalities. Sophos researchers note that threat actors often refine their strategies after campaigns, suggesting ongoing risks.

PJobRAT is an Android Remote Access Trojan that re-emerged in 2023, targeting users in Taiwan. Initially known for targeting Indian military personnel, it now disguises itself as benign apps like ‘SangaalLite’ and ‘CChat’, distributed via defunct WordPress sites operational from January 2023 to October 2024, with domain registrations dating back to April 2022. The malware is spread through counterfeit applications resembling legitimate messaging services, prompting users to grant extensive permissions. Enhanced capabilities allow it to execute shell commands, access data from any app, root devices, and communicate with command-and-control servers via Firebase Cloud Messaging and HTTP. The campaign appears to have concluded, highlighting the evolving tactics of threat actors. Users are advised against installing apps from untrusted sources and to use mobile threat detection software.

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.

In 2021, PJobRAT, an Android Remote Access Trojan (RAT), targeted Indian military personnel through deceptive apps. A new campaign was discovered in 2023, focusing on users in Taiwan, with malicious apps like ‘SangaalLite’ and CChat disguised as instant messaging applications. These apps were available for download from WordPress sites, which have since been taken down. The campaign began in January 2023, with domains registered as early as April 2022, and the latest sample detected in October 2024. The number of infections was low, indicating a targeted approach rather than a broad attack. The distribution methods remain unclear, but may involve SEO poisoning, malvertising, or phishing. Once installed, the apps request extensive permissions and feature basic chat functionality. Recent versions of PJobRAT have shifted from stealing WhatsApp messages to executing shell commands, allowing greater control over compromised devices. PJobRAT communicates with its command-and-control (C2) servers using Firebase Cloud Messaging (FCM) and HTTP, enabling the upload of various data types, including SMS, contacts, and files. The now inactive C2 server was located in Germany.

The Android Spynote malware disguises itself as a legitimate antivirus application called "Avast Mobile Security" to exploit vulnerabilities in Android systems. It requests permissions associated with antivirus apps, bypasses user restrictions, and excludes itself from battery optimization settings. Spynote simulates user gestures and displays misleading system update notifications to maintain its presence and hinder detection. Its primary target is cryptocurrency accounts, aiming to extract private keys and balance information for assets like Bitcoin, Ethereum, and Tether. The malware captures user credentials, stores them on the device's SD card, and employs obfuscation and evasion techniques to complicate detection efforts. It can detect virtual environments to evade analysis and monitors system settings to resist uninstallation attempts. Spynote is distributed through phishing sites that mimic the legitimate Avast download page, hosting malicious APKs named Avastavv.apk.
