Hackers target Taiwan with malware delivered via fake messaging apps

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 Android Malware Masquerades as Dating and Messaging Apps to Target Military Personnel

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 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.

PJobRAT makes a comeback, takes another crack at chat apps

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.

Signal, Telegram and WhatsApp are not built the same

Jeffrey Goldberg, editor-in-chief of The Atlantic, was inadvertently added to a Signal group chat with high-ranking White House officials, highlighting the complexities of secure messaging applications. Signal is known for its robust end-to-end encryption and open-source nature, which allows for independent security audits. WhatsApp, owned by Meta, also uses end-to-end encryption but raises privacy concerns due to its corporate ties. Telegram offers cloud-based messaging with optional end-to-end encryption for "Secret Chats," but its standard chats lack the same level of security as Signal or WhatsApp. The incident underscores the importance of understanding the security features and vulnerabilities of different messaging platforms.

Which is the most secure messaging app? Expert weighs in after U.S. war plan leak blunder

A significant intelligence breach occurred when Jeffrey Goldberg, editor-in-chief of The Atlantic, was inadvertently added to a sensitive Signal group chat that included discussions about U.S. military operations targeting Houthi rebels in Yemen, involving Vice President JD Vance and Defense Secretary Pete Hegseth. Senate Democratic Leader Chuck Schumer described it as "one of the most stunning breaches of military intelligence." Experts emphasized that the breach resulted from human error, not flaws in encryption technology. Signal is considered the gold standard for secure messaging due to its end-to-end encryption and lack of metadata collection. Other platforms like iMessage and WhatsApp have varying levels of security, with iMessage requiring both parties to use Apple devices for full protection, and WhatsApp collecting metadata. Telegram does not enable end-to-end encryption by default for standard messages. The incident highlights that even the most secure messaging applications cannot prevent breaches caused by human oversight.

How secure is signal? The messaging app used by Trump team to share war plans

Senior officials from the Trump administration accidentally shared sensitive military discussions on the encrypted messaging platform Signal, leading to calls from Democratic lawmakers for a congressional investigation. A journalist was mistakenly included in a group chat, giving him access to confidential conversations about military operations in Yemen. Signal is an open-source messaging platform known for its end-to-end encryption and prioritizes user privacy by retaining minimal data. User chats and contacts are stored locally on devices, and the app allows for automatic deletion of conversations. Signal operates independently of government servers and does not use governmental encryption methods. Cybersecurity expert Rocky Cole stated that the risk of discussing sensitive information on Signal is less about its security and more about the potential compromise of the mobile device itself.

What is Signal?

A magazine journalist was unexpectedly included in a group chat of U.S. national security officials on the Signal messaging app, just hours before President Donald Trump authorized airstrikes against Iran-backed Houthi rebels in Yemen. The National Security Council is investigating how the journalist's phone number was added to this secure communication channel. Signal is an application that supports direct messaging, group chats, and voice and video calls, employing end-to-end encryption. It allows for group chats of up to 1,000 participants and includes a feature for messages to self-destruct after a set period. Signal is considered secure but not immune to hacking, and it raises concerns about compliance with open records laws. Government officials are increasingly using encrypted messaging applications, with many having accounts linked to government-issued and personal cell phones. Signal was created by Moxie Marlinspike, who combined two open-source applications, and is overseen by the nonprofit Signal Foundation, which operates without advertisers or investors.

What is Signal, the messaging app Trump team used to share war plans?

Top officials from the Trump administration mistakenly included journalist Jeffrey Goldberg in an encrypted chat on the Signal messaging app, discussing military strategies against Yemen's Houthi rebel group. This incident has led to calls from Democratic and some Republican lawmakers for a congressional investigation into a potential security breach. Goldberg reported being added to the chat on March 13, which aimed to coordinate U.S. military responses to Houthi attacks on shipping in the Red Sea. The inclusion of an outsider in the chat raises concerns about the protocols for sharing classified information on commercial messaging platforms. Under U.S. law, mishandling classified information can result in criminal charges, although it is unclear if any laws were violated in this case. Signal is known for its secure messaging capabilities, utilizing end-to-end encryption, and does not track or store user data beyond basic account information. The app has gained popularity among privacy advocates, journalists, and government organizations.

Signal event: Why US and European officials rely on the messaging app

A recent incident involved The Atlantic's editor-in-chief in a Signal chat among senior officials from the Trump administration discussing military actions in Yemen. Signal was chosen for its robust security features, including end-to-end encryption that prevents interception by intermediaries. Signal operates as an independent non-profit, unlike WhatsApp, which is owned by Meta. Its popularity is growing in political circles, with recommendations from both the European Commission and Parliament for secure communications. The guidelines noted an increase in threats to telecommunications infrastructure and recommended Signal when corporate tools are unavailable. A recent leak of U.S. national defense plans was due to human error, not Signal's encryption flaws.
