TCPdump is a CLI-based packet capture tool that is widely used for real-time traffic inspection and analysis on Unix/Linux systems.

TCPshark is a variant CLI tool used similarly for packet analysis.

Although Wireshark is a powerful network protocol analyzer, it requires a GUI. Therefore, it is not suitable for environments without a graphical interface.

The Python code snippet:

Uses socket.socket(AF_INET, SOCK_STREAM), which indicates TCP communication

Connects to a remote server (192.168.1.10 on port 80)

Sends a manual HTTP GET request

Receives the response using s.recv()

This is a classic example of TCP/IP socket programming, specifically creating a simple TCP client to communicate with a web server. It does not monitor traffic or crawl websites --- it sends a crafted request and prints the response.

Thus, this code best fits:

If IPS and SIEM logs do not give enough insight into a file's behavior, the next logical step is to review the Antivirus solution logs. These logs often provide detailed behavior analytics such as:

File actions and access patterns

Registry modifications

File execution history

The Cisco CyberOps guide emphasizes AV logs as critical forensic artifacts for understanding endpoint-based infections, especially when beaconing or suspicious activity is suspected.

The Wireshark capture shows a series of HTTP requests and responses:

The client (10.1.21.101) sends a GET request for /Lk9tdZ.

The server (209.141.51.196) responds with HTTP/1.1 302 Found, which is a standard HTTP status code indicating a redirection.

The subsequent GET request from the client is for /files/1.bin, which indicates it followed the redirect.

This behavior confirms that the server is issuing an HTTP 302 redirect from the initial request path /Lk9tdZ to /files/1.bin. This is often observed in malware command-and-control behavior or file download staging.

Option A is incorrect: 302 is a status code, not a data size.

Option C is incorrect: port 49723 is a source/destination ephemeral port, not a redirect target.

Option D is incorrect: communication is over HTTP, not HTTPS (which would indicate encryption).

The alert indicates a WebDAV Stack Buffer Overflow, which is a memory corruption attack targeting the stack, a common vector for remote code execution or denial-of-service (DoS).

To mitigate such exploits, two effective system-hardening techniques are:

C . Address Space Layout Randomization (ASLR): Randomizes memory addresses used by system and application processes, making it difficult for attackers to predict where their malicious code will be executed.

E . Data Execution Prevention (DEP): Prevents execution of code from non-executable memory regions such as the stack, thus stopping buffer overflow attacks from successfully executing payloads.

Both are well-established protections against stack-based buffer overflow attacks and are strongly recommended in the Cisco CyberOps Associate guide and general security best practices.
