North Korea-The Newest Cyber Threat in Town

Certainly by now, the world has heard about the infamous cyberattack against Sony purportedly carried out by North Korea.  Although numerous denials have been given, the attack appears to have been perpetrated by a despotic regime in retaliation for the simple act of making a satirical movie.  I’ll let the ridiculousness of that statement sink in for a minute.  Now onto the practical matter at hand; how can the world’s most isolated nation pull off such a technologically advanced attack?  To put this in perspective, consider the following.  If you do a web search for “North Korea at night”, you can plainly see the lack of electricity or at least visible lighting as compared to its southern neighbor.  I remember standing on the DMZ looking into North Korea.  The normally wooded area was clear cut by the residents and soldiers not to provide a defensive line of sight, but for a fuel source....because there was nothing else.  Despite these limitations, North Korea actually has a fairly well developed cyber warfare capability. 

According to a 2014 report published by Hewlett-Packard researchers North Korea is seriously committed to the cyber aspect of their national defense.  The hermit kingdom’s Unit 121 is considered to be one of the world’s premier cyber organizations, third in size only behind the United States and Russia.  South Korea estimates this team is comprised of anywhere between 3000 and 6000 staff.  According to the HP report, some of the more notable hacks North Korea has managed to pull off include:

(2004) Gained access to 33 of 80 South Korean military wireless communication networks. 

(2004) Hacked into the US State Department, US Defense Department, and South Korean defense networks during discussions over nuclear missile testing.

(2007)  Tested a logic bomb which led to the UN ban of certain pieces of hardware to North Korea.

(2009)  DarkSeoul DDoS targeted South Korean and U.S. government, media outlets, and financial websites.

(2011) North Korea disrupted South Korean GPS signals, attempted a DDoS attack against Incheon airport and Nonghyup bank.

(2013)  DarkSeoul DDoS attacked South Korean government’s DNS server and South Korean financial institutions. (Osborne, 2014)

The Sony attack however appears to be the metaphorical straw.  Shortly after the hack and Sony’s subsequent decision to pull “The Interview” from release, North Korea’s limited access to the Internet was cut off for approximately 10 hours.  It is unknown whether this was a deliberate cyberattack against the regime or simply technical difficulties with the nation’s four official networks (Robertson & Strohm. 2014).  Researchers point out however that this occurrence is definitely out of the norm.  And while the U.S. State Department won’t comment on the reports, there appears to be no lack of likely actors willing to target the regime.  Anonymous made headlines in 2013 for its #OpNorthKorea campaign which targeted various North Korean websites.  In the end, the Sony hack illustrates the larger issue at hand; the next battlefield will undoubtedly occur in cyberspace.
