The US Army has recently published a document named ‘North Korea Tactics’ where the 332-page “Army Training Publication (ATP) 7-100.2,” dated July 24, describes “North Korean tactics for use in Army training, professional education, and leader development.”
A section of the document discusses “computer warfare,” which it says consists of “attacks focusing specifically on computer systems, networks, or nodes.” Examples given are “Unauthorized access (hacking) of information systems for intelligence-collection purposes” and “Insertion of malicious software (viruses, worms, logic bombs, or Trojan horses).”
There are over 6,000 members in Bureau 121, many of them operating from other countries, such as Belarus, China, India, Malaysia, and Russia, the document has mentioned.
According to the U.S. Army document, “North Korean computer hackers have even been able to access secure systems and steal South Korean war plans.”
In 2009, North Korea’s Mirim College was graduating approximately 100 cyberspace hackers per year for the Korean People’s Army, the document adds.
