Strange calls stick mobile users with high charges

HA NOI (VNS)— BKAV, the country's leading IT and telecom security firm, has warned mobilephone users that when they get a missed call from an unidentified number, they should not call back.

According to BKAV, a number of mobilephone users noticed missed calls from strange numbers, usually a long chain of digits. When they called back, they heard a ringtone but could not establish a connection.

However, their mobile accounts were charged the rate for international calls.

BKAV said it has identified those numbers as coming from satellite phones, or satphones, a type of mobilephone that connects to orbiting satellites instead of terrestrial cell sites.

The company said it has produced a security software for smartphone users that could prevent users from being contacted by fraudulent numbers.

The app, called BKAV Mobile Security, can be downloaded from the application stores of many smartphone operating systems including iOS, Android and BlackBerry. — VNS
