 LATEST THREATS....
FlexiSpy - 03/30/2006

FlexiSpy is a Symbian OS based trojan that records phone calls and SMS messages and sends them to a remote server. It is meant to be an actual application that is designed for this purpose. But it runs stealthily without an indication of its purpose and hence is classified as a trojan.

 
Commwarrior.B variant - 03/07/2006

This worm is a minor variant of Commwarrior.B localized to Spanish. All the messages used by Commwarrior to spread is translated to Spanish by this variant. This is already detected by SMobile as a Generic Commwarrior.

 
Crossover - 3/1/2006

This Trojan cross-infects mobile devices from a PC. When executed from Win32, the Trojan checks what version the current OS is; if it is not Windows CE or Windows Mobile, the virus makes a copy of itself and puts a startup command in the registry key of local-machine-current-version-run. The trojan then quietly waits for an ActiveSync connection to be detected; it can wait indefinitely. When an ActiveSync connection is detected, the trojan automatically copies itself to the handheld device and remotely executes the trojan. The handheld device is now infected. The Trojan will then begin to delete documents on the handheld. Not known to be in the wild.

This explanation is taken from http://www.informit.com/articles/article.asp?p=458169&seqNum;=3 published by MobileAV.org

 
RedBrowser.A - 03/01/2006

A Trojan which is a J2ME based midlet. It sends SMS messages to a particular phone number, resulting in the user having to pay for the messages. It masquarades itself by pretending to allow access to WAP sites using SMS messages. However, each time the SMS message is sent to the same number: 1615. This malware is completely in Russian, which might make the possibility of it affecting other countries low.

 
Symbos_cardtrp.a
