Jailbreaking
Mobile phone users sometimes "jailbreak" their devices, removing restrictions to allow them to run unauthorized software. This exposes users to unexpected threats. (Image: ThinkStock)
Broken Locks
Some apps do not impose strict security. For example, they may not require a PIN to access sensitive data. If a phone is lost or stolen, the owner's bank account could be at risk. (Image: ThinkStock)
