The ping command is designed to test connectivity between two computers. hping3: calls hping3 program.-S: specifies SYN packets. Teardrop attacks. Since the machine receiving such packets cannot reassemble them due to a bug in TCP/IP fragmentation reassembly, the packets overlap one another, crashing the target network device. Without proper protection, these packets can cause an operating system to freeze or crash as it unable to process them. I was able to exploit the system and get the local password. CaptureFilter ×1.
