Technical Details

This virus interferes with a Novell NetWare network. If the supervisor logs in from an infected machine, the virus tries to create a new user called HYPERVISOR (The Hypervisor).

The virus adds SUPERVISOR SECURITY_EQUALS to the 'HYPERVISOR' user object. HYPERVISOR has no password. The virus copies the servers bindery files (2.xx NET$BIND.SYS, NET$BVAL.SYS; 3.xx NET$OBJ.SYS, NET$PROP.SYS, NET$VAL.SYS) to the SYS:LOGIN/ directory.

The HYPERVISOR user can be seen from SYSCON.

The virus contains several bugs.
