Is anyone aware of any (FOSS) software (presumably intrusion detectors or indicators of compromise) for mobile phones that might help flag or even prevent such attacks?
TinyCheck [0] comes to mind, but it isn't truly mobile. TrackerControl [1] and Guardian Firewall [2] are perhaps the closest to something like this but concentrate on privacy more than on security.
