North Korea’s Internet back after probable attack
Dec 23rd
North Korea’s Internet connection with the world has returned to service after a nine and a half hour outage that followed hours of patchy performance.
The cause of the outage is unknown, although several experts think it was probably due to an external distributed denial of service (DDoS) attack. This involves flooding web servers and other Internet hardware with so much traffic that they become overloaded and cannot respond to legitimate traffic. It’s not an actual hack of the system and so the situation is normalized soon after the DDOS flow of traffic stops.

South suspects North Korean hackers hit on June 25
Jul 17th
The South Korean government says it suspects hackers in North Korea were behind a series of cyber attacks last month.
The attacks took place on June 25, the anniversary of the beginning of the Korean war, and continued for several days. When they began, several South Korean government and private-run websites were defaced or taken offline.
The main evidence behind the South’s accusations was the discovery of an IP address linked to North Korea and similarities in software code between the June 25 attack and previous attacks, the Ministry of Science, ICT and Future Planning, said Tuesday.

Analyzing the June 25 DDoS attacks
Jun 27th
Tuesday’s series of denial of service attacks on major North Korean websites caused delays and frustration for legitimate users but doesn’t appear to have been as large or successful as the first round of attacks in late March and early April this year.
Analysis by NorthKoreaTech.org of data related to the attacks shows the so-called “OpNorthKorea” mission was most successful during its first few hours and then appeared to slowly tail off.
Denial of service attacks involve firing off requests for pages to websites. If enough requests can be sent, the site ends up overloaded and no one gets anything. Success of More >
Hackers attack North, South Korean websites
Jun 25th
The previously announced June 25 attack on North Korean websites by hackers working under the “Anonymous” name took an unexpected turn on Tuesday when several South Korean sites were hit with attacks. The actions coincided with the release of what hackers said were stolen files on American military personnel.
The North Korean attack did start as scheduled and appears to have been initially successful. Most major North Korean websites are either inaccessible or difficult to access, indicating they are being hit by a denial of service attack. This involves overwhelming a web server with requests so it gets tied up and More >

KCNA hits back at Anonymous
Jun 22nd
The Korean Central News Agency (KCNA) has attacked claims by international hacker collective Anonymous that it managed to steal North Korean military secrets from computer servers. The attack came in a commentary on Friday, just days before Anonymous plans to launch a cyber-attack on North Korean websites.
Earlier this week, a Twitter user claiming to represent Anonymous hackers said the group had managed to infiltrate North Korean servers on the country’s domestic intranet and access sensitive information.
“We completed serveral attacks on your internal Websites and inside your local intranets,” the group said in a message posted to the Pastebin website, which allows More >

Anonymous attacks North Korean sites again
May 13th
A weekend attack on North Korean websites staged by members of the Anonymous hacker group appears to have caused some problems for the sites.
Connections to several major Pyongyang-based sites, including the Korean Central News Agency and Voice of Korea, were slow although successful in several tests done in the first few hours of the coordinated attack, which began at 1am GMT on Sunday.
Those results are in contrast to a previous series of attacks that took the sites offline for days. That difference was acknowledged by an Anonymous Korea Twitter message:
North Korea has reconfigured its Internet connection since the last round More >
Anonymous promises more website attacks this weekend
May 11th
Members of the Anonymous hacking group say they are planning to re-launch attacks on North Korean websites from Sunday. [Updated. See below.]
In messages posted to Twitter, several Anonymous members said the “#OpNorthKorea” attacks would resume on May 12 from 1am GMT, that’s 10am in the morning Pyongyang time.
OpNorthKorea first began in late March, shortly after North Korean media said relations between it and South Korea were “at a state of war.” It took the form of a distributed denial of service (DDoS) attack, which involves flooding a website with so many requests for data that it becomes overloaded.
The attacks were successful in More >
Hacker publishes North Korean website hit list
May 7th
An unidentified Internet user posting under the name of the Anonymous hacking collective has published a “hit list” of North Korean websites.
The list is said to be related to a coordinated attack that hackers appear to be planning for June 25. The action is part of “OpNorthKorea,” which previously took sites in North Korea and China offline in a series of distributed denial of service attacks.
The message appears to have been translated from another language, probably Korean, into English and includes sites based in China, Japan, the U.S., Spain and a single website in Pyongyang.
The source of the list is unclear More >
