A new report has found that a number of popular iOS and Android apps have what amounts to a minor security fault, in that they allow users to make an unlimited number of attempts to login to an associated account, thus making them vulnerable to password hacking for attackers who have physical access to the device, such as thieves or overzealous law enforcement. Security firm AppBugs says "dozens" of apps are affected, including Slack, iHeartRadio, Dictionary, SoundCloud and many others.
