New Cabir variant

We have just received two very similar Cabir variants, purportedly from the author. This person claims that he/she has the source code and can make new worms instead of only Cabir variants.

We are conducting a detailed analysis and complete testing: we will post details when this is complete. In the meantime, the author asserts that the new Cabir, (Cabir.e in our naming system) “don’t show any message, only install and auto-sent to anothers cellphones…”. Symbian users should be very careful and check back for additional information.

The original Cabir, btw, required user interaction twice before completing installation routines.
