The threat actor responsible was a Romanian hacker by the name of Razvan Cernaianu, who used the username ‘TinKode’ (Info Security, 2012). However, the precise details of how he manipulated his intrusion against the TCP/IP port 21 are not known, as he has not publically disclosed his method for hacking the server (Smith, 2011). This involves creating programs for cycling through combinations of letters, numbers and symbols until the password for an FTP server is cracked (Goyal & Redhu, Hacking via Password Cracking, 2014). ![]() A technique known as ‘brute force’ could also have been used. There are a number of different ways in which access could have been gained to the FTP server. It would also be possible to upload malicious files onto the server in order to cause damage to it or remotely control the server without permission (Goyal & Redhu, Hacking on FTP Server: A Review, 2014).

In April and May of 2011, NASA’s Goddard Flight Center was hacked and screenshots displaying classified information from it were posted on an online blog. In order to prevent future incidents of this nature, NASA could employ a range of different measures aimed at boosting its security, including improving its DMZ, re-routing port numbers and installing effective NIDS and PIDS to detect intrusions. It was carried out by Romanian hacker Razvan Cernaianu, who could have been motivated by a desire for entertainment, hunger for fame, or a desire to become a paid, ethical hacker. The 2011 hacking of NASA’s FTP server represented an avoidable breach of the organization’s security and privacy. ![]()
