This backdoor may arrive bundled with malware packages as a malware component.

It opens an instance of Internet Explorer and injects its code to stay memory-resident.

This backdoor connects to an IP address. Once a connection is established, it allows a remote user to execute commands on the system, thus compromising system security. It also connects to the same IP address to send and receive information.

g_destroy_consumer

G_CONSUMER(9)						   BSD Kernel Developer's Manual					     G_CONSUMER(9)

NAME

     g_new_consumer, g_destroy_consumer -- GEOM consumers management

SYNOPSIS

     #include <geom/geom.h>

     struct g_consumer *
     g_new_consumer(struct g_geom *gp);

     void
     g_destroy_consumer(struct g_consumer *cp);

DESCRIPTION

     A GEOM consumer is the backdoor through which a geom connects to another GEOM provider and through which I/O requests are sent.

     The g_new_consumer() function creates a new consumer on geom gp.  Before using the new consumer, it has to be attached to a provider with
     g_attach(9) and opened with g_access(9).

     The g_destroy_consumer() function destroys the given consumer and cancels all related pending events.  This function is the last stage of
     killing an unwanted consumer.

RESTRICTIONS
/CONDITIONS
     g_new_consumer():

	   The geom gp has to have an orphan method defined.

	   The topology lock has to be held.

     g_destroy_consumer():

	   The consumer must not be attached to a provider.

	   The access count has to be 0.

	   The topology lock has to be held.

RETURN VALUES

     The g_new_consumer() function returns a pointer to the newly created consumer.

EXAMPLES

     Create consumer, attach it to given provider, gain read access and clean up.

	   void
	   some_function(struct g_geom *mygeom, struct g_provider *pp)
	   {
		   struct g_consumer *cp;

		   g_topology_assert();

		   /* Create new consumer on 'mygeom' geom. */
		   cp = g_new_consumer(mygeom);
		   /* Attach newly created consumer to given provider. */
		   if (g_attach(cp, pp) != 0) {
			   g_destroy_consumer(cp);
			   return;
		   }
		   /* Open provider for reading through our consumer. */
		   if (g_access(cp, 1, 0, 0) != 0) {
			   g_detach(cp);
			   g_destroy_consumer(cp);
			   return;
		   }

		   g_topology_unlock();
		   /*
		    * Read data from provider.
		    */
		   g_topology_lock();

		   /* Disconnect from provider (release access count). */
		   g_access(cp, -1, 0, 0);
		   /* Detach from provider. */
		   g_detach(cp);
		   /* Destroy consumer. */
		   g_destroy_consumer(cp);
	   }
