Starting in April, the South Korean government required that cellphones sold to anyone below the age of 19 be equipped with approved monitoring software that would allow the user's parents to monitor their phone use, report their location, and more. Now, however, researchers have discovered that one of the most popular of the approved apps, called Smart Sheriff, may not actually be very smart to have on one's phone. Researchers from Citizen Lab and Cure53, at the request of the Open Technology Fund, have analyzed the code of Smart Sheriff, and found that it actually endangers, rather than protects, the users. Reports the Associated Press, in a story carried by the Houston Chronicle: Children's phone numbers, birth dates, web browsing history and other personal data were being sent across the Internet unencrypted, making them easy to intercept. Authentication weaknesses meant Smart Sheriff could easily be hijacked, turned off or tricked into sending bogus alerts to parents. Even worse, they found that many weaknesses could be exploited at scale, meaning that thousands or even all of the app's 380,000 users could be compromised at once.
