The virus extends money to phone users

Security company Sophos has released a warning message to owners of Nokia Series 60 mobile phones and Symbian-based mobile devices on a computerized trojan named Viver. Mobile device control automatically sends messages to a number of SMS service charges at intervals of 15 seconds.

' The number that the Trojan uses to send the message is a short range with a high service fee. This is a computer virus that does not harm the device but is at risk of causing great economic losses, "said SophosLabs observer Anna Szaley.

The current trend is that many SMS content service providers have dedicated short numbers for easy-to-lease business with the ability to pay for service charges.

Anna Szaley points out: " The telecom provider manages subcontractors by assigning a code and password is a rather lacking mechanism for hackers to subscribe to a cheap number, and then use it for the purpose of extending money from mobile subscribers '.

Last month, both Kaspersky and Symantec found this type of Trojan called Viver. According to Kaspersky, the service fee of the number that Viver has attached to the receiver is up to 7 USD / SMS sent.

' We tracked the Viver with many variants, its speed is also listed as fast, only less than 24 hours have 200 people downloaded to their mobile phones without knowing. If 200 victims have a virus infected cell phone, within 24 hours the number of sent SMS allows spammers to earn $ 500 per day , 'analyst Aleks Gostev of Kaspersky Lab calculated.

According to analyst Aleks Gostev, " in May alone there were 3 types of trojans with similar modes of operation that we recognized. From there we can predict that if there are any tricks to For money, virus programmers will not miss the opportunity . '
