Detecting Exploitation and Covert Communications Tools

Which netcat parameter causes netcat to run as a listener that automatically restarts when a connection is dropped?

  • A -u
  • B -l
  • C -p
  • D -L
Explanation

The -L option enables persistent listening: netcat re-listens after a client connection closes or drops. The -l option alone only puts netcat into listen mode.
