On Sunday, female ice hockey players from North and South Korea joined one another for a training session before the upcoming Winter Olympics. Players from the two Koreas are to compete together as a united team for the events hosted in Pyeongchang, South Korea, which are scheduled to start on February 9; Seoul’s Unification Ministry said. The cross-border gesture is part of diplomatic efforts to ease tensions on the divided Korean Peninsula and the team was approved by the International Olympic Committee.

The International Olympic Committee selected Pyeongchang in 2011 to host the event, marking South Korea’s first opportunity since the 1988 Summer Olympics in Seoul. The earlier event was marred by violence as North Korea had bombed a South Korean flight several months prior, killing over 100 and boycotted the event. Inter-Korean relations have changed considerably in the ensuing thirty years, including the two sending unified teams for table tennis and youth football in other non-Olympic competitions.

The announcement that the two countries would compete together was a stated goal of South Korean President Moon Jae-in. Last year, he announced the proposal and the two nations went into discussion this month. After two weeks, they made the announcement to field a consolidated 35-strong team of ice hockey players and have joint skiing exercises with both team coaches involved.

According to Yonhap News Agency estimates, about 80% of South Koreans support dialogue, but the move to have a joint team has been controversial. Over 10,000 South Korean citizens sent a petition to South Korean President Moon opposing the union and a group of North Korean defectors held a protest at the South Korean National Assembly on January 24, tearing apart photos of the North Korean leader, Kim Jong-un. Public support for eventual reunification of the Korean peninsula has waned in recent years, with the younger generation more skeptical of the possibility.

On Friday, a network of diverse Internet-connected devices targeted the Dyn domain registration service provider. It took down Dyn clients, including several popular websites such as Twitter, Netflix, Spotify, Reddit, New York Times, and Wired.

The attack involved targeting Dyn’s domain name system servers with a large volume of requests, rendering it incapable of serving replies to legitimate requests — a DDoS (distributed denial of service) attack. Users’ browsers and other clients sent requests to Dyn to resolve the respective web sites’ domain names to an IP, but did not get a reply within the time required.

The first attack started at about 7am local time (UTC-4) and was resolved in two hours. A second attack started at mid-day, and a third attack started at about 4pm local time. Tens of millions of malicious request sources were observed, interfering with legitimate Dyn traffic.

The reports noted the malicious devices included internet-connected devices — not only servers and desktops, but also webcams, digital video recorders, routers — referred to as the Internet of Things.

On Friday evening Dyn said a security company Flashpoint and a cloud services provider Akamai identified symptoms of malware Mirai participating in the attacks. The malware infects the devices by brute forcing their passwords. This strategy may work as a consequence of users’ negligence towards password security of stationary devices, which the users do not directly interact with in their everyday life while leaving them exposed to the Internet.

Matthew Prince, the CEO of an Internet infrastructure company Cloudflare said it’s a known issue, “There’s nothing really new about [this type of DDoS attack]. We’ve seen them for at least the last three years, they tend to be difficult to stop”.

Public release of Mirai source code was announced at Hackforums on September 30.

Dyn’s corporate headquarters are in New Hampshire.
