Sitemap “Currently, Premium SMS scams are the biggest threat to smartphone users, regardless of OS,” explained Derek Halliday, Lookout. ”They’re relatively simple to set-up, and have the potential to pay-off big. But there are constantly new threats evolving, ranging from aggressive ad networks, through to Trojans and new forms of malware. Mobile phones have become our wallet, contact list, communications, and more. You wouldn’t leave your bank account open to everyone, so why take the same chances with your phone when it contains so much information? But at the same time, you shouldn’t be scared of using all the features on your device – Lookout gives people the freedom to enjoy their smartphone to the full. ”
