Google has recently removed fake Signal and Telegram apps from its Play store. These apps were available on Play for several months and had been downloaded multiple times before being taken down. The fake Signal app was also available in the Samsung app store and on a website that mimicked the official Signal.org. Both apps were built on open source code from Signal and Telegram and contained an espionage tool known as BadBazaar. This Trojan has been linked to a China-aligned hacking group and has previously targeted Uyghurs and other Turkic ethnic minorities. The malicious apps had the ability to monitor messages and contacts, as well as access private information such as device details, location data, and Google account information. This incident highlights the importance of being cautious when downloading apps and the need for strong security measures.
The fact that fake Signal and Telegram apps were available on the Google Play store for several months before being removed is concerning. It shows that malicious actors can exploit the app store’s security measures and potentially put users at risk. In this case, the fake Signal app was also available in the Samsung app store and on a dedicated website, further increasing its reach and potential impact.
Both apps were built on open source code from Signal and Telegram, which means they had the appearance of legitimacy. This highlights the need for users to be cautious when downloading apps, even from trusted sources. It is important to verify the authenticity of the app and its developer before installing it on a device.
The inclusion of the BadBazaar espionage tool in these fake apps is particularly alarming. This Trojan has been linked to a China-aligned hacking group known as GREF, and it has previously targeted Uyghurs and other Turkic ethnic minorities. The fact that the malware was also shared in a Uyghur Telegram group further supports its connection to previous targeting by the BadBazaar malware family. This incident raises concerns about state-sponsored cyberespionage and the potential impact on vulnerable communities.
The malicious apps had the ability to monitor sent and received messages and contacts if users connected their infected device to their legitimate Signal number. This is a common practice when installing Signal for the first time. By doing so, the malicious app would send private information such as device details, location data, and Google account information to the attacker. This highlights the importance of being cautious when granting permissions to apps and the need for strong security measures to protect sensitive data.
In conclusion, the presence of fake Signal and Telegram apps in the Google Play store raises significant security concerns. Users need to be cautious when downloading apps, even from trusted sources, and should verify the authenticity of the app and its developer. The inclusion of the BadBazaar espionage tool in these apps highlights the potential for state-sponsored cyberespionage. It is crucial for individuals and organizations to prioritize cybersecurity and adopt strong security measures to protect against such threats.
