Risk: Informational
FlexiSPY Light monitors SMS messages that are sent and received, as well as recording the duration and history of all calls made and received.
The company that makes the software, Vervata, boasts that FlexySPY Light is "the world's first spy application designed and built exclusively for the mobile phone". It also states that it is "absolutely undetectable by the user". It cites its possible uses as monitoring a spouse or child's mobile behaviour.
The product has been labelled as malware but Vervata states: "FlexiSPY is not a Trojan, nor a virus and does not require the purchase of anti-virus products to remove it. An uninstall option is provided for the user, so the application can be removed at any time. Configuration settings are also available to allow frequency of connections, thereby allowing the user to minimise network connections to once daily if required."
Whether or not FlexiSPY Light is actually deemed to be malware is still a point that is being argued over, but if you and your spouse have a trust issue, perhaps it should be tackled in a different manner.
