"Paladin, the national anti-stalking advocacy service, says tech firms need to do more to protect victims if tech is misused. Rachel Horman-Brown, chairwoman of the charity, said: "Many victims are tracked and monitored through their phones or tablets by spyware. "So actually stalkers don't even need to physically get a tracking device on the victim to be able to monitor them. "Spyware is concerning as it can enable a stalker to switch on the camera on a victim's mobile phone, so that they can see and hear what is happening. They can also read and send text messages from the victim's phone, as well as tracking their whereabouts.""
