Lasco.A is a worm that only affects cellular phones that use the operating system Symbian. Initially, it aims Nokia series 60 cellphones, but other devices based in the same software could also be affected.
Lasco.A is very similar to the worm Cabir.A. Their main difference lies in the fact that, in addition to spread via Bluetooth (which is a technology that allows wireless connections of electronic devices), Lasco.A also inserts itself in all the SIS files it finds in the affected phone. SIS files are installers for phone applications, so that when a user runs a modified installer, it also installs this worm.
However, keep in mind that Lasco.A needs the user intervention in order to be run on the cellphone. Before the malicious file is installed, the user receives a security warning.
Lasco.A is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
