Full story

Google has quietly rolled out a new security feature in Android that alerts users when their device connects to a suspicious network or fake cell tower. The feature, part of Android’s ongoing push to improve mobile security, relies on a combination of network scanning and threat intelligence to flag potentially dangerous connections. Users must manually enable the setting in their device’s security menu, which is currently available on most modern Android devices running recent versions of the operating system.

The move comes as concerns grow over the prevalence of fake cell towers, also known as IMSI catchers or Stingrays, which can intercept calls, messages, and data. While these devices are often used by law enforcement or malicious actors, they pose a significant risk to everyday users. Android’s new feature aims to mitigate this threat by providing real-time warnings when a device connects to an untrusted network. However, the effectiveness of the feature depends on users actively enabling it and staying vigilant about security updates.
