Android IMSI-Catcher Detector

The Android IMSI-Catcher Detector (AIMSICD) identifies IMSI-Catchers, also known as "StingRay" or "Cellular Interception". These are false mobile towers that intercept data between a mobile phone and genuine service towers, a tactic known as a Man-In-The-Middle (MITM) attack. AIMSICD uses detection methods such as verifying tower information consistency, LAC/Cell ID consistency, and neighboring cell information. It also monitors signal strength, detects silent SMS and FemtoCells, and prevents silent app installations.

IMSI-Catchers are commonly used due to their untraceability. They are often covertly used by law enforcement agencies to obtain records of cell phone users during events like protests. They can intercept conversations, text messages, and data, and can locate a user or identify who is in a specific area. Identity thieves can also use them to monitor and manipulate communications, often to steal passwords or credit card data. AIMSICD aims to combat these privacy invasions.
