- to other network computers infected with: Troj/Kuang, Troj/Sub7, Troj/NetDevil, W32/MyDoom, W32/Bagle and Troj/Optix
- to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WebDav (MS03-007), IIS5SSL (MS04-011) (CAN-2003-0719), UPNP (MS01-059) and Dameware (CAN-2003-1030)
