Urgent: New ‘Sturnus’ Trojan Bypasses WhatsApp, Telegram Encryption – Are You at Risk?
November 21, 2025, 14:23 CET – A newly discovered and highly sophisticated Android Trojan, dubbed ‘Sturnus’ by security researchers at ThreatFabric, is sending shockwaves through the cybersecurity world. This isn’t your average malware; Sturnus has the alarming ability to circumvent the end-to-end encryption of popular messaging apps like WhatsApp, Telegram, and Signal, potentially exposing your most private conversations. This is a breaking news development with significant implications for users across Europe, and beyond.
How Sturnus Works: A Deep Dive into the Threat
Unlike many Android threats that rely on phishing or exploiting vulnerabilities in the operating system itself, Sturnus employs a clever technique: screen capture after decryption. This means even if your messages are encrypted while in transit and at rest, Sturnus can still steal their content once it’s displayed on your screen. ThreatFabric describes Sturnus as an “advanced threat in development,” already configured to target financial institutions in Southern and Central Europe. While currently limited in its deployment, its capabilities are deeply concerning.
The Trojan doesn’t stop at message interception. Sturnus is a full-featured malware package capable of:
- Banking Credential Theft: It presents fake login pages mimicking legitimate banking apps, tricking users into entering their credentials.
- Full Device Control: Attackers can silently control your device, observe your activity, and even insert text – all without your knowledge.
- Complete Remote Access: Sturnus grants attackers complete remote control over infected devices.
- Administrative Privileges: The malware attempts to gain administrative privileges, making it incredibly difficult to remove.
The History of Android Security: A Growing Challenge
Android, launched in 2003 and acquired by Google in 2005, has become the world’s most popular mobile operating system. Built on the Linux kernel, it offers a vast ecosystem of apps through the Google Play Store. However, its open nature and widespread adoption also make it a prime target for malware. The evolution of Android security has been a constant arms race between developers and malicious actors. Early Android versions were notoriously vulnerable, but Google has steadily improved security features with each iteration, including enhanced app sandboxing and regular security updates. Despite these improvements, threats like Sturnus demonstrate that sophisticated attackers continue to find ways to bypass defenses.
Why Encrypted Messaging Isn’t Always Enough
WhatsApp, Telegram, and Signal have become synonymous with secure communication, thanks to their end-to-end encryption. But Sturnus highlights a critical vulnerability: encryption protects data in transit and at rest, but it doesn’t necessarily protect data displayed on your screen. This is a reminder that security is a layered approach. Strong encryption is essential, but it must be combined with good security practices, such as keeping your device updated, being cautious about the apps you install, and avoiding suspicious links.
Protecting Yourself from Sturnus and Similar Threats
While Sturnus is currently focused on Europe, the potential for wider deployment is real. Here’s what you can do to protect yourself:
- Keep Your Android Device Updated: Install the latest security patches as soon as they become available.
- Install a Reputable Mobile Security App: A good antivirus app can detect and remove malware.
- Be Wary of Suspicious Links and Attachments: Don’t click on links or open attachments from unknown sources.
- Review App Permissions: Pay attention to the permissions requested by apps before installing them.
- Enable Two-Factor Authentication: Add an extra layer of security to your accounts.
- Monitor Your Bank Accounts Regularly: Look for any unauthorized transactions.
The emergence of Sturnus serves as a stark reminder that the threat landscape is constantly evolving. Staying informed and proactive is crucial to protecting your digital life.
