Trapster, a popular app that alerts drivers of police speed traps and roadway hazards, was recently targeted by hackers who may have stolen users' email addresses and passwords, the company has warned. All those who have registered an account with the site should assume their information was among the compromised data, the company warned. According to its website, Trapster, which is available for Apple, BlackBerry, Android and other smartphones and GPS devices, has more than 10 million users. The company began notifying affected users this week and said it has rewritten software code to prevent a similar incident from occurring in the future. – AM
