Challenge Text

• A system administrator hasn't smiled in days. Legend has it, there is a DNS joke hidden somewhere in www.jerseyctf.com. Can you help us find it to make our system administrator laugh?

Hint

• How are IP addresses pointed towards domain names?

Solution

• Use any of the following dig, nslookup, or host commands to search the DNS records of www.jerseyctf.com:
  • dig www.jerseyctf.com txt
  • dig -t txt www.jerseyctf.com +short
  • host -t txt www.jerseyctf.com
  • nslookup -type=txt www.jerseyctf.com
• The flag will be in a string: jctf{DNS_J0k3s_t@k3_24_hrs}
