Networks AODV

Rushing attack

 Rushing attack is a zero delay attack and more effective when the attacker nearby source or destination node.On-demand routing protocols like AODV and DSR are more vulnerable to this attack, because whenever source node floods the route request packet in the network, an adversary node receives the route request packet and sends without any hop_count update and delay into the network. Whenever the legitimate nodes receive the original source request packets, they are dropped because legitimate nodes,would have already received packet from the attacker and treat the currently received packets as duplicate packets. Thus, adversary is included in active route & disturbs the data forwarding phase. Rushing attack can be taken place at source side or destination side or at the middle.

** The following conditions the rushing attacker is not included in active route

1. When source and destination nodes have direct communication link

2. When source and destination nodes have better route than rushing attackers route

** Rushing attack is more effective when attacker near to source or destination node

Rushing attacks:

 Rushing attacks mainly classified into two types:

1.    Rushing attack followed by jellyfish attack

2.    Rushing attack followed by byzantine attack

Rushing attacker disturbs the data forwarding phase by either jellyfish or byzantine attack.

Rushing attacks implementation in aodv routing protocol

The following scenario consists of 25 nodes. In which 7, 8 and 10 nodes are rushing attacks other nodes are non-malicious.

To create multiple rushing attackers in aodv protocol

·         In aodv.h, the following blue colour lines needs to be added to define rushing attackers

/*

      * History management

      */

    

double               PerHopTime(aodv_rt_entry *rt);

nsaddr_t malicious;

·         In aodv.cc the following blue colour lines needs to be added to initialize the attackers

// To initialize the rushing attackers

int

AODV::command(intargc, const char*const* argv) {

if(argc == 2) {

Tcl&tcl = Tcl::instance();

if(strncasecmp(argv[1], "id", 2) == 0) {

tcl.resultf("%d", index);

return TCL_OK;

    }

                    if(strncasecmp(argv[1], "rushingattack", 13) == 0) {

     malicious= 1000;

        return TCL_OK;

    }

                 

AODV::AODV(nsaddr_t id) : Agent(PT_AODV),

btimer(this), htimer(this), ntimer(this),

rtimer(this), lrtimer(this), rqueue() {

index = id;

seqno = 2;

bid = 1;

  LIST_INIT(&nbhead);

  LIST_INIT(&bihead);

malicious=999;

·         Malicious nodes 7, 8 and 10 generate malicious route requests using following blue colour code

Each rushing attacker do not increase the hop_count and simply broadcast without delay. Other than rushing attackers, they will follow the AODV protocol to broadcast route request

//add blue colour lines in send route request packet

/*

  * Can't reply. So forward the  Route Request

  */

else {

ih->saddr() = index;

ih->daddr() = IP_BROADCAST;

if (malicious==1000)

rq->rq_hop_count += 1;

   // Maximum sequence number seen en route

if (rt) rq->rq_dst_seqno = max(rt->rt_seqno, rq->rq_dst_seqno);

if (malicious==1000)

forward((aodv_rt_entry*) 0, p, 0);

else

forward((aodv_rt_entry*) 0, p, DELAY);

 }

// add the blue colour lines code in forward packet

if (ih->daddr() == (nsaddr_t) IP_BROADCAST) {

 // If it is a broadcast packet

assert(rt == 0);

if ((ch->ptype()==PT_AODV) && (malicious!=1000)) {

     /*

*  Jitter the sending of AODV broadcast packets by 10ms

      */

     Scheduler::instance().schedule(target_, p, 0.01 * Random::uniform());

   } else {

     Scheduler::instance().schedule(target_, p, 0.);  // No jitter

   }

 }

  

·         Rushing Attackers can do two attacks: Byzantine and Jellyfish attacks

/*

  * If the route is up, forward the packet

  */

                                                  

if(rt->rt_flags == RTF_UP) {

assert(rt->rt_hops != INFINITY2);

//Byzantine attack can be done : drop all /selective packets

//                       Modify [or]injectflase packets

//Here,  only dropping packets are considered

if((ch->ptype()!=PT_AODV) && (malicious==1000))

                                                   {

                           if(t < CURRENT_TIME)

                                                   {

                                               t=t+2;

                             drop(p, DROP_RTR_NO_ROUTE);

       }

//Jellyfish attack can be done two ways: delaying packets [or] re-ordering //packets.

//Here, only delaying packets and 0.8 can be varied till the good put is zero

else                                            

forward(rt, p, 0.8); 

 }

else

forward(rt, p, NO_DELAY);

 }

·         Since, all attackers drop the packets due to no route to destination, attackers have to disable the send[error]

The following blue colour lines code disables the send (error)

 // add in route resolve function (AODV::rt_resolve(Packet *p) )

else {

 Packet *rerr = Packet::alloc();

structhdr_aodv_error *re = HDR_AODV_ERROR(rerr);

 /*

  * For now, drop the packet and send error upstream.

  * Now the route errors are broadcast to upstream

  * neighbors - Mahesh 09/11/99

  */    

assert (rt->rt_flags == RTF_DOWN);

re->DestCount = 0;

re->unreachable_dst[re->DestCount] = rt->rt_dst;

re->unreachable_dst_seqno[re->DestCount] = rt->rt_seqno;

re->DestCount += 1;

#ifdef DEBUG

fprintf(stderr, "%s: sending RERR...\n", __FUNCTION__);

#endif

if(malicious==1000) drop(p, DROP_RTR_NO_ROUTE);

else

sendError(rerr, false);

drop(p, DROP_RTR_NO_ROUTE);

To define the rushing attackers in tcl add these lines after node initializations

$ns at 0.0 "[$n5 set ragent_] rushingattack"

$ns at 0.0 "[$n7 set ragent_] rushingattack"

$ns at 0.0 "[$n8 set ragent_] rushingattack"

Above scenario example tcl  file : rushing attacks

Rushing attack aodv.cc file : aodv.cc

                         aodv.h file : aodv.h

What is Mobile Forensics?

Mobile forensics is a scientific methodology used for investigating the evidence of a crime or accident on a suspect's mobile device including smartphones and smart watches. More than 75% of digital evidence is from mobile devices, so mobile forensics is key to successful investigation of crimes in today's digital world.

There are diverse mobile phone manufacturers as well as OS platforms. There is also a huge number of apps and private data on mobile phones. Some of the data may even be encrypted. We have been in the security business since 1996 and are best equipped to handle a mobile forensic investigation.
