Snowblind malware uses an Android security feature to bypass security

Android users, particularly those in Southeast Asia, be on high alert!

A new kind of malware called “Snowblind” has been discovered, specifically designed to steal login credentials from banking apps. This malware is particularly cunning as it exploits a built-in Android security feature to bypass existing protections within banking apps.

Snowblind doesn’t rely on brute force tactics. Instead, it cleverly infects seemingly legitimate apps by altering their code.

This prevents the app from detecting when accessibility features – functionalities intended to assist users with disabilities – are being used for malicious purposes. In this case, Snowblind leverages accessibility services to steal your login credentials and even view your phone’s screen remotely.

What makes Snowblind even more concerning is its ability to exploit a security feature called “seccomp” (secure computing) that’s present in the Android operating system. “Seccomp” is supposed to identify and prevent tampering attempts within apps.

However, Snowblind injects malicious code that bypasses “seccomp” before it can activate its security checks. This grants the malware free rein to utilize accessibility services for its nefarious purposes.

To further tighten its grip, Snowblind can also disable security features commonly used by banking apps, such as fingerprint or facial recognition (biometric authentication) and two-factor verification.

With these additional security layers bypassed, stolen login credentials become much more valuable to attackers.

The good news is that there are ways to protect yourself from Snowblind. Here are some key points to remember:

  • Download Apps Wisely: Snowblind primarily infects users who install apps from untrusted sources. This emphasizes the importance of sticking to the official Google Play Store for downloading apps. The Play Store has built-in security measures to help prevent malware from infiltrating its app selection.
  • Be Extra Cautious in Southeast Asia: While the exact number of infected devices is unknown, reports suggest Snowblind is currently most active in Southeast Asia. If you’re located in this region, exercise even greater caution when downloading apps.

According to Google, there are currently no known instances of Snowblind being present in apps available on the Google Play Store. So, sticking to the Play Store offers a significant layer of protection.

By downloading apps only from trusted sources and remaining informed about new malware threats, you can significantly reduce the risk of falling victim to Snowblind or similar banking malware. If you suspect your device might already be infected, consider running a security scan with a reputable antivirus app. By taking these precautions, you can help safeguard your banking information and keep your Android device secure.
