According to NetQin, the cybercriminals usually install the spyware on the phone by sending an MMS containing the spyware to users to lure them to click.

Once installed, the spyware will turn on the Conference Call feature of the device without users’ awareness. When users are making phone calls, the spyware automatically adds itself to the call to monitor the conversation. Additionally, the Spy.Felxispy mobile malware can remotely turn on the speaker on the phone to monitor sounds around users without the users’ awareness. Apart from that, the spyware is also capable of synchronizing the messages the user received and delivered to the monitoring phone, compromising users’ privacy.
