A critical Android flaw has been discovered that allows cybercriminals to insert hidden Unicode characters in app notifications.
These invisible characters can disguise malicious links as legitimate ones, potentially leading to malware downloads without user knowledge.
The exploit takes advantage of Android's interpretation of Unicode in notifications, creating a mismatch between visual content and system processing.
This technique can be used in phishing campaigns, drive-by downloads, or credential theft.
The flaw is not limited to a specific Android version, making numerous devices and apps vulnerable, especially messaging and email apps.
The emergence of the Crocodilus banking Trojan further compounds Android's security issues, using Accessibility Services for complex attacks.
Crocodilus overlays fake screens on banking apps, records keystrokes, steals login details, and manipulates contact lists for scam calls.
Security experts recommend monitoring notifications, activating Google Play Protect, updating devices, limiting Accessibility Service access, and using reputable security apps.
Users are advised to be cautious of suspicious notifications and adopt defensive measures against evolving cybersecurity threats on Android.
Experts urge Google and developers to address the Unicode flaw promptly to enhance system transparency and secure mobile ecosystems.
