Which benign sоlid оvаriаn mаss secretes andrоgens?

There is аn аctive Telnet cоnnectiоn frоm а client 10.0.2.9 to a Telnet server 10.0.2.10 (see the upper figure). An attacker successfully sniffed the last packet sent from the server, as shown in the lower figure. 1.png 2.png 1. If the attacker wants to terminate this connection using Netwox, a spoofed Reset packet should be sent to the client on behalf of the server. Please finish this command: ~$ sudo netwox 40 --ip4-src _[A]_ --ip4-dst _[B]_ --tcp-src _[C]_ --tcp-dst _[D]_ --tcp-reset --tcp-seqnum _[E]_ 2. If the attacker wants to perform a session-hijacking attack on the server, a spoofed packet with Shellcode (say, 'xxx') should be sent to the server on behalf of the client. Please finish this command: ~$ sudo netwox 40 --ip4-src _[A]_ --ip4-dst _[B]_ --tcp-src _[C]_ --tcp-dst _[D]_ --tcp-window 2000 --tcp-ack --tcp-seqnum _[E]_ --tcp-acknum _[F]_ --tcp-data “xxx” 3. If the attacker wants to delete a very important file, secret.txt, in the server, what should be the payload used in the above hijacking attack (xxx in the data field)? If you don't know the firm code, describe the XXX in terms of formatting and functions. 4. Bonus: once the session hijacking succeeds Wireshark shows lots of retransmission packets from both ends. Please explain the possible reason.
