A security flaw in Android's notification system allows hackers to deceive users into triggering hidden app actions.
Research identifies a flaw in how Android processes certain Unicode characters within notifications, leading to misinterpretation of links.
Invisible or special Unicode characters embedded within URLs can cause Android to interpret visible text and actionable link differently.
This flaw enables attackers to redirect users to different sites or trigger app actions without user consent.
Malicious actors can use URL shorteners and trusted-looking text to make attacks less detectable.
The vulnerability affects major apps like WhatsApp, Telegram, Instagram, Discord, and Slack, as shown through various tests.
Standard defenses like antivirus software may miss these exploits as attackers manipulate UI behavior.
Endpoint protection tools are recommended for broader detection based on behavioral anomalies to counter such attacks.
Users are advised to stay cautious with notifications and links, particularly from suspicious sources or URL shorteners, until a formal fix is deployed.
