SEOUL: North Korea's internet<\/a> appears to have been hit by a second wave of outages in as many weeks, possibly caused by a distributed denial-of-service (DDoS) attack, researchers said on Wednesday.

The latest incident took place for about six hours on Wednesday morning local time, and came a day after North Korea conducted its fifth missile test his month.

Junade Ali, a cybersecurity researcher in Britain who monitors a range of different North Korean web and email servers, said that at the height of the apparent attack, all traffic to and from North Korea was taken down.

\"When someone would try to connect to an IP address in North Korea, the internet would literally be unable to route their data into the country,\" he told Reuters.

Hours later, servers that handle email were accessible, but some individual web servers of institutions such as the Air Koryo airline, North Korea's ministry of foreign affairs, and Naenara, which is the official portal for the North Korean government, continued to experience stress and downtime.

Internet access is strictly limited in North Korea. It is not known how many people there have direct access to the global internet, but estimates generally place the figure at a small fraction of one percent of the population of about 25 million.

Seoul-based NK Pro, a news site that monitors North Korea, reported that log files and network records showed websites on North Korean web domains were largely unreachable because North Korea's Domain Name System (DNS<\/a>) stopped communicating the routes that data packets should take.

A similar incident was observed on Jan. 14, NK Pro reported.

The simultaneous nature of the server outages suggested a DDoS attack, in which hackers try to flood a network with unusually high volumes of data traffic in order to paralyse it, Ali said.

\"It's common for one server to go offline for some periods of time, but these incidents have seen all web properties go offline concurrently. It isn't common to see their entire internet dropped offline.\"

During the incidents, operational degradation would build up first with network timeouts, then individual servers going offline and then their key routers dropping off the internet, Ali said. \"This indicates to me that this is the result of some form of network stress rather than something like a power cut.\"

首尔:北韩互联网似乎受到第二波停机三天内,可能引起的分布式拒绝服务(DDoS)攻击,研究人员周三表示。

最新的事件发生当地时间周三上午大约6个小时,和前一天,北韩进行了导弹试验他的第五个月。

网络安全研究员Junade阿里在英国监控朝鲜一系列不同的web服务器和邮件服务器,说的身高明显的攻击,所有的流量和从朝鲜拍摄下来。

“当有人会尝试连接到一个IP地址在朝鲜,互联网就无法路线数据进入这个国家,”他告诉路透。

小时后,服务器处理电子邮件访问,但一些个人web服务器空气等机构的高丽航空公司,朝鲜外交部和Naenara,这是朝鲜政府的官方门户网站,继续经历压力和停机时间。

互联网访问是在朝鲜严格限制。现在还不知道有多少人有直接访问全球互联网,但估计通常把图的一小部分人口约2500万的百分之一。

汉城NK Pro,监视朝鲜的新闻网站,报道,乐动扑克网站和网络日志文件记录显示朝鲜web域主要是遥不可及的,因为朝鲜的域名系统(DNS)停止通信数据包应该采取的路线。

类似的事件是观察到1月14日NK Pro报道。

服务器宕机的同步性质提出了DDoS攻击,黑客试图在洪水异常大量的网络数据流量,以瘫痪,阿里说。

“这是常见的一个服务器离线了一些时间,但这些事件同时看到所有web属性离线。它不是常见他们的整个网络离线下降。”

事件期间,操作退化将首先建立与网络超时,那么个人服务器离线,然后他们关键路由器送互联网,阿里说。“我这表明这是某种形式的网络压力的结果,而不是像一个停电。”
