Fake Google Play Store pages are spreading Trojan malware that can steal your financial data

CTM360, a cybersecurity firm in Bahrain, has reported a new threat called the PlayPraetor trojan, which is distributed through malicious websites that imitate trusted sources like the Google Play Store. Users who visit these counterfeit sites may download an app disguised as a legitimate APK file, which requests extensive permissions, including access to accessibility services and SMS messages. Once installed, PlayPraetor functions as spyware, capturing keystrokes and clipboard activity, and specifically targets banking applications by scanning for them on infected devices. It sends a list of these apps to the attacker's server to steal banking credentials. The fraudulent links are often shared via Meta Ads and SMS messages, making it crucial for users to be cautious with links from these sources. The malicious sites closely resemble legitimate ones, so users should verify the website's spelling and URL. Deceptive advertisements and messages are commonly used to entice users into clicking links that lead to these sites. Users should be skeptical of anything that creates urgency or offers unrealistic deals. Excessive permission requests during app downloads should raise red flags, especially for unnecessary accessibility services. It is recommended to use reputable antivirus software for mobile protection, enable Google Play Protect, and avoid sideloading apps from unofficial sources to prevent potential threats.

You may be one of the 11 million people with these infected Android apps

Google's Android operating system has been compromised by a variant of the Necro Trojan malware, which has infiltrated several applications, including modded versions of WhatsApp and Spotify. Kaspersky identified the Necro Trojan, first discovered in 2019, as a significant threat that infects devices through compromised apps, downloads additional malicious payloads, and can enroll devices in subscription services without user consent. Among the affected legitimate apps on the Google Play Store are the Wuta Camera app, with 10 million downloads, and Max Browser, with over 1 million downloads. Both have been removed by Google, and users are advised to uninstall them. The malware has also been found in various modded gaming apps. The attack has primarily affected Android users in Russia, Brazil, and Vietnam, and the number of infected devices may be higher than reported due to unverified downloads.

Necro Trojan infiltrates Google Play and Spotify and WhatsApp mods

Modified versions of mobile applications can pose significant risks, particularly due to the resurgence of the Necro Trojan malware, which has infiltrated both popular apps and unofficial counterparts. A Spotify mod called Spotify Plus was found to contain a custom Application subclass that initialized an SDK named adsrun, which communicated with a command-and-control server and transmitted encrypted data. This server provided a link to download a PNG file with a hidden payload, leading to the execution of malicious code. The Necro loader has also been embedded in legitimate applications on Google Play, affecting over 11 million Android devices. Infected apps include the Wuta Camera app, downloaded over 10 million times, starting from version 6.3.2.148, and the Max Browser app, with over a million installations, starting from version 1.2.0. Additionally, WhatsApp mods in unofficial channels were found to harbor the Necro loader, utilizing Google’s Firebase Remote Config as a command-and-control mechanism. Other infected applications identified include game mods for Minecraft, Stumble Guys, Car Parking Multiplayer, and Melon Sandbox. The modular architecture of the Necro Trojan allows for flexible updates and the introduction of new malicious modules, enhancing its persistence and evasion capabilities. Various Necro modules serve distinct functions, such as creating network tunnels and displaying intrusive advertisements. The malware has been reported in regions like Russia, Brazil, and Vietnam, with thousands of attacks thwarted globally.

These Popular Android Apps Might Be Infected With the Necro Trojan

Recent findings indicate that certain Google Play apps and unofficial modifications of popular applications are being exploited to spread the Necro trojan malware, which can log keystrokes, steal sensitive information, install additional malware, and execute remote commands. The Necro trojan, first identified in 2019, was previously found in the PDF maker app CamScanner. A new version has been detected in the Wuta Camera app and Max Browser on the Google Play Store, both of which have since been removed by Google. Unofficial 'modded' versions of popular apps like Spotify and WhatsApp, often available on third-party websites, are also spreading the malware. These modified apps can contain malicious SDKs that trigger the trojan payload upon user interaction. The malware can download files, install applications, and subscribe users to paid services without consent. Users are advised to be cautious when downloading apps from third-party sources.
