An open-source, terminal-based SnoopSnitch alternative optimized for MediaTek chipsets. It operates as a network stealth utility, sending low-level AT commands directly to the modem to block carrier-side location triangulation, lock onto trusted cells, and suppress radio telemetry.
While SnoopSnitch is heavily tailored for Qualcomm-based diagnostics, Mushroomtek brings cellular defense and anomaly-checking features to MediaTek-based Android devices.
Non-MediaTek Modems: While designed and optimized primarily for MediaTek platforms, this utility might also work on non-MediaTek modems that expose an AT command interface (such as some Unisoc or Qualcomm devices). However, please test on other hardware at your own risk.

The modem stops feeding surrounding tower signal data back to the carrier, breaking multi-tower trilateration.
Cell/Band Locking -- Forces the modem onto specific EARFCNs and blocks forced handovers to monitored or congested cells.
Modem Silence -- Suppresses unsolicited report codes (CURC=0) to reduce the radio's software footprint on the network side.
Automated Rotation -- Randomized cell lock cycling to mimic natural movement patterns and avoid automated network anomaly detection.
Online Verification (BeaconDB) -- Integrates with BeaconDB (an open-source Mozilla Location Service replacement) to dynamically verify connected cell tower IDs against public databases to warn against potential IMSI-Catchers or fake base stations without requiring any API keys.
Unlike traditional cellular monitors (like SnoopSnitch) which act as passive Intrusion Detection Systems (IDS) by analyzing traffic and alerting you after a potential anomaly or IMSI-catcher interaction has occurred, Mushroomtek takes an active mitigation approach.
It does not just watch; it continuously reconfigures the modem's state to actively block tracking vectors, suppress neighbor reporting, and prevent forced handovers before network-side triangulation can take place.
