Inside DPRK’s Unit 121

DPRK.jpg

Military plan­ners and secu­rity experts have inten­si­fied their shouts of con­cern about the devel­op­ment of cyber weapons and the dis­tinct pos­si­bil­ity of a cyber war. Cyber war­fare is not new. It has been in mod­ern mil­i­tary doc­trine for the past decade not to men­tion the num­ber of ter­ror­ist groups who have threat­ened the use of cyber weapons against the west. However, what has changed is the num­ber of coun­tries that posess these capa­bil­i­ties today.

The North Korean mil­i­tary cre­ated a new unit that focuses solely on cyber war­fare. The unit, dubbed Unit 121, was first cre­ated in 1998 and has steadily grown in size and capa­bil­ity since then. Interest in estab­lish­ing cyber war forces shouldn’t come as a sur­prise to any­one, but North Koreas intense effort stands out among the top ten nations devel­op­ing cyber weapons.

Unit 121 Capabilities Assessment:

Force Size: Originally 1,000 — Current Estimate:17,000

Budget: Total mil­i­tary bud­get $6 bil­lion USD. Cyber Budget $70+ mil­lion. North Koreas mil­i­tary bud­get is esti­mated to be the 25th largest in the world.

Goal: To increase their mil­i­tary stand­ing by advanc­ing their asym­met­ric and cyber warfare.

Ambition: To dom­i­nate their ene­mys infor­ma­tion infra­struc­ture, cre­ate social unrest and inflict mon­e­tary damage.

Strategy: Integrate their cyber forces into an over­all bat­tle strat­egy as part of a com­bined arms cam­paign. Additionally they wish to use cyber weapons as a lim­ited non-​​war time method to project their power and influence.

Experience: Hacked into the South Korea and caused sub­stan­tial dam­age; hacked into the U.S. Defense Department Systems.

Threat Rating: North Korea is ranked 8th on the Spy-​​Ops cyber capa­bil­i­ties threat matrix devel­oped in August of 2007.

Capabilities

Cyber Intelligence/​Espionage: Basic to mod­er­ately advanced
weapons with sig­nif­i­cant ongo­ing devel­op­ment into cyber intelligence.

Offensive Cyber Weapons: Moderately advanced dis­trib­uted
denial of ser­vice (DDoS) capa­bil­i­ties with mod­er­ate virus and mali­cious code capabilities.

North Korea now has the tech­ni­cal capa­bil­ity to con­struct and deploy an array of cyber weapons as well as battery-​​driven EMP (elec­tro mag­netic pulse) devices that could dis­rupt elec­tron­ics and com­put­ers at a lim­ited range.

In the late spring of 2007, North Korea con­ducted another test of one of the cyber weapons in their cur­rent arse­nal. In October, the North Koreans tested its first logic bomb. A logic bomb is a com­puter pro­gram that con­tains a piece of mali­cious code that is designed to exe­cute or be trig­gered should cer­tain events occur or at a pre­de­ter­mined point of time. Once trig­gered, the logic bomb can take the com­puter down, delete data of trig­ger a denial of ser­vice attack by gen­er­at­ing bogus transactions.

For exam­ple, a pro­gram­mer might write some soft­ware for his employer that includes a logic bomb to dis­able the soft­ware if his con­tract is terminated.

The N Korean test led to a UN Security Council res­o­lu­tion ban­ning sales of main­frame com­put­ers and lap­top PCs to the East Asian nation. The action of the United Nations has had lit­tle impact and has not deterred the North Korean mil­i­tary for con­tin­u­ing their cyber weapons devel­op­ment program.

Keeping dan­ger­ous cyber weapons out of the hands of ter­ror­ists or out­law regimes is next to impos­si­ble. As far back as 2002, White House tech­nol­ogy adviser Richard Clarke told a con­gres­sional panel that North Korea, Iraq and Iran were train­ing peo­ple for inter­net war­fare. Most infor­ma­tion secu­rity experts believe that it is just a mat­ter of time before the world sees a sig­nif­i­cant cyber attack tar­geted at one spe­cific coun­try. Many sug­gest the dan­ger posed by cyber weapons rank along side of nuclear weapons, but with­out the phys­i­cal dam­age. The signs are there. We need to take action and pre­pare for the impact of a cyber war.

    You know though,I would like to ask North Korea these questions,“How many days did it take for Kim Il Sung & Kim Chong Il to cre­ate the heav­ens & the earth(because they are wor­shipped as gods in North Korea)”,“Why did Kim Il Sung & Kim Chong Il name a dog a dog,a cow a cow,& a cat a cat,”& then finally,“If I was trapped on a desert island & prayed to Kim Il Sung & Kim Chong Il,would they hear my prayers?” Of course,I know its rude & dis­re­spect­ful to mock another person’s “religion.”

    A det­o­na­tion at an alti­tude low enough to keep the effects within N.K. should due the trick, and pro­vide a warn­ing for oth­ers.

    North Korea will most likely not go to war with the US. The DPRKs leader Kim Jong Il has only one goal: stay in power (keep his play­boy lifestyle) and a war will bring a sure end to that. However if war did come. expect a lot of dead US ser­vice­men. The NKPA (North Korean People’s Army) is 1 mil­lion men strong and could mount a nasty war. Their equip­ment is bad (hell they use biplanes for recon air­craft) those sol­diers they have are tough.

    Yes,but what if some hacker was able to take down the entire net system,shut down the inter­net itself?North Korea would try to take down South Korea’s infra­struc­ture through cyber war­fare & a mas­sive bal­lis­tic mis­sile bar­rage before it would launch its “mal­nour­ished mil­lion man army & rick­ety tanks & air­craft into South Korea.The big ques­tion about North Korea’s mis­siles are their max­i­mum range,can they reach Guam or Alaska? Will we have up an ade­quate mis­sile defense to stop them,would our mis­sile defense be affected by a mas­sive inter­net shutdown?

    Matt Jacobs,
    North Korea could kill a lot of US ser­vice­men? With all due respect, that is about as stu­pid as liken­ing inter­net hack­ing with nuclear holo­caust.
    I don’t know why you think North Korea’s troops are ‘tough’. They are phys­i­cally weaker and smaller than South Koreans by a wide mar­gin. Our troops are sit­ting behind the most for­ti­fied bor­der in the world, and the North Koreans lack the tools required to breach that bor­der in strength.
    Even if the North Koreans COULD attack other than shoot­ing artillery at civil­ians, their mil­i­tary is con­sid­er­ably weaker than the Iraqi forces the US faced in the Gulf War, and if you remem­ber, we rolled over them.
    Wars aren’t won by “tough fight­ers” any more. They are won by well trained, well equipped, well led fight­ers. Even if Nork troops could best our forces were they to com­pete on the “Survivor” real­ity show, that means noth­ing when it comes to actual warfare.

    #1. Nork mis­siles are not much of a threat right now because they are unre­li­able and non-​​nuclear. Conventional bal­lis­tic mis­siles are not mil­i­tar­ily effec­tive because their pay­load and accu­racy are inad­e­quate to do more than kill some civil­ians if fired at a city.
    #2. You can’t shut down the whole inter­net, that is the whole point of why DARPA orig­i­nally devel­oped the inter­net: sur­viv­abil­ity. The best any­one could do is take out domain name servers for lim­ited peri­ods of time, which would inter­fere with civil­ian use, but would not affect the mil­i­tary. Militaries have their own com­mu­ni­ca­tion net­works any­way.
    #3. The US mil­i­tary does not rely on the inter­net. Even if you shut the whole inter­net down, this would only be a mild annoy­ance at most for the US mil­i­tary, if it affected them at all. Poorer coun­tries, like China, North Korea, etc. are much more likely to try to use the inter­net for mil­i­tary com­mu­ni­ca­tions because they cant afford a seper­ate, bet­ter com­mu­ni­ca­tions network.

    A few points
    Your Point #2 If you think tak­ing out a domain server is the best some­one can do you should con­sider look­ing at what hap­pened to Estonia ear­lier this year. Russian attack­ers dis­rupted credit and debit card trans­ac­tions for nearly three weeks.
    A gen­eral point — the inter­net has been used to covertly acquire sev­eral pieces of clas­si­fied tech­nol­ogy plans due to secu­rity breaches. Just recently Oak Ridge National Labs (DOE) has it’s vis­i­tors (classified/​cleared and gen­eral) breached and the name, ssn, DOB and clear­ance data exposed. At the same time an attack on Clearancejobs​.com breached and got the names and email addresses exposed. The attacks using the inter­net are more fre­quent and more sig­nif­i­cant than mot peo­ple real­ize.
    Your Point #3 In 2007 the DoD expe­ri­enced over 80,000 net­work attacks because their sys­tems do use the internet.

    it is ironic that we amer­i­cans (with all do respect) lack the intel­li­gence that the rock army as it is called N. korean troops will cre­ate prob­lems for our troops. my grand­fa­ther is one of the true com­bat sol­diers that fought in the for­got­ten war and let me be the first to say N. korea will #### up amer­ica! and we should nuke the enemy N. korea and then some.

    OK, let’s drag this out. The guy says N. Korea has increased its cyber unit to 17,000 per­son­nel. With a $70 mil­lion dol­lar bud­get, that is $4,117 per per­son. Now, these aren’t just aver­age Joe’s, they would demand bet­ter pay, and there train­ing would have to be expen­sive also. Finally, none of this even includes the cost of equip­ment, most of which would have to be imported. I would think the unit is no more than 1,000 per­son­nel, prob­a­bly with aver­age equip­ment and train­ing. Of course, there is always a chance they have a true genius work­ing for them, oh wait, this is North Korea, if he was a true genius, he would defect.

    This is one of the sil­li­est things I have read here in a long time. Yes, if you wanted to you could clog up some net­works in the US (indi­vid­ual sites only) but with many years of hav­ing to deal with mal­ware pay­loads all crit­i­cal net­works in the US have mul­ti­ple redun­dan­cies, and mil­i­tary traf­fic goes over it’s own fiber. You can hack for intel­li­gence, but unless you have a fine grained view of your oppo­nents net­works and that oppo­nent has sin­gle points of fail­ure for you to com­pro­mise, you won’t do any­thing. Keeping in mind that NK only has a sin­gle point that it’s inter­nal net­works meet the inter­net, iden­ti­fy­ing an attack orig­i­nat­ing from there and shut­ting it down are triv­ial.
    And bat­tery pow­ered EMP devices? What, are you kid­ding me? What are they going to do with that? Sneak in teams of agents to shut down a cou­ple of ATM machines? That’s as much power as they’ll have.

    Lets look at this objec­tively. I served in Korea, and while they have a mil­lion man army, they are starved and poorly equipped. We would lose a lot of the troops we have in coun­try cur­rently, but we would win the war in the long run. The issue I saw while in coun­try, is that there are a LOT of young South Koreans who want a uni­fied Korea and are will­ing and able to fight AGAINST the US and ROK units if it came down to a war. I was flat out told by a KATUSA (Korean Augmentee to the United States Army) that he would shoot me and join the North if war started. Needless to say he was reported and I never saw him again any­where near my unit. I believe they posted him on the bor­der so he would not get the chance, how­ever the sen­ti­ment is there. The older gen­er­a­tions want us there, the younger ones do not.

    I was in an intel­li­gence unit for 6yrs. and I think alot of unin­formed peo­ple talk about var­i­ous com­bi­na­tions ie;China&North Korea or what allies would join with them, that is a very small coun­try and big land forces are not going to be a chal­lenge once they have to be put on ships and moved to Japan or Indonesia.We have a SOUSS(hope That is correct)system in place that will iso­late their armies and sink them wher­ever they want to move. Are they goo­ing to march south?No-march North?why.We should be keep­ing very close and inplace agents in the coun­tries of the middle-east!And even for the coun­tries there we have a great under­stand­ing of their thought processes and can con­troll their com­mu­ni­ca­tions at any time we wish.Remember we broke both Germany and Japan’s code before or short after the start of hos​til​i​ties​.As mid-​​eastern kings may be set­ting up mass sys­tems of interupt­ing our com­mu­ni­ca­tion sys­tems we are already in place!There is so much going on behind the scenes and press releases that the American peo­ple will never know about we do have a whole NEW line of defense and that line is not privy to but to a few and that does not include the CIA.EMR’s are only a piece of our offense​.So again I plead don’t despair.The Def.Dept.and “others“have some incred­i­ble advances that are in place.Over-Under-&-Around!Peace be with you all.Donot despair!!
