LONDON (IT BOLTWISE) – A new threat to Android users is causing a stir: the Sturnus Trojan can read encrypted messages from apps such as Signal, Telegram and WhatsApp. Although the encryption itself has not been cracked, the malware uses a sophisticated method to intercept messages on the screen after they have been decrypted.

The security of encrypted messages is crucial for many users, be it companies or private individuals. But a new threat called the Sturnus Trojan is putting this security into question. This malware targets Android smartphones and can read encrypted messages from apps such as Signal, Telegram and WhatsApp by intercepting the messages on the screen after they have been decrypted.
The Sturnus Trojan uses Android’s Accessibility Services to read everything that appears on the screen in real time. This includes contacts, full conversation histories, and the content of incoming and outgoing messages. This method bypasses the protections of end-to-end encryption because messages are only intercepted after they have been decrypted.
The malware is still in the development or testing phase, according to security researchers at ThreatFabric. Nevertheless, it is already capable of not only intercepting messages, but also gaining complete control over the device and stealing banking data. These capabilities make the Sturnus Trojan particularly dangerous.
To protect themselves from this threat, users should be careful not to download apps from unreliable sources and keep the Google Play Protect feature enabled. They should also be careful when granting apps access to Accessibility Services and ensure that this is only done for trusted applications.
The discovery of the Sturnus Trojan once again illustrates that the security of devices and data cannot be guaranteed through encryption alone. A compromised device can reveal all the information stored on it, regardless of how secure the encryption is. Therefore, it is important to always remain vigilant and take security measures to protect the integrity of your data.
