Mobile Trojan Pretends As Anti-Virus Software
On Friday, June 10, 2005, anti-virus vendor F-Secure announced a variant of the Cabir worm aimed at Nokia smartphones pretends to be legitimate anti-virus software.
The Skulls.L trojan is a variant of the Skulls.C trojan except it masquerades as an illegally copied version of F-Secure's Mobile Anti-Virus program. The trojan is aimed at smartphones based on the Nokia Series 60 platform, which is based on the Symbian OS.
The Cabir virus activates only when users try to run the bogus programs and when the Skulls.L is activated, it will display a message saying: "F-Secure Antivirus protect you against the virus. And don`t forget to update this!".
F-Secure warned users to download its anti-virus files only from F-Secure servers and noted that the official files are signed so that the source can be verified.

F-Secure said, "Skulls.L is a malicious SIS file trojan that replaces the system applications with non-function versions." Once installed, it places Symbian-specific versions of the Cabir worms on the phones and disables legitimate anti-virus programs, including those from F-Secure.
