The opening ceremony of the Winter Olympics was marked by an online attack to servers of POCOG on Friday.
The PyeongChang Organizing Committee for the Olympics and Paralympics Events (PyeongChang Organizing Committee for the 2018 Olympic & Paralympic Games or POCOG) confirmed that there was an aggressive cyber behavior that caused IPTV television programs in the Press Center to malfunction, according to reports of Yonhap News.
According to the publication, POCOG stated that its servers were hit by an "unknown intruder" during the launch ceremony and that it shut down the servers (and its website) to prevent further damage.
The site, which was closed during the opening ceremony held on Friday, was reactivated at 8am local time on Saturday.
At present we do not know details, but its analyst McAfee Advanced Threat Research, Ryan Sherstobitoff reported that his team discovered a parchange of malicious documents targeting the Winter Games just days before the opening ceremony.
"The document contained the same metadata properties as those used by GoldDragon and sought access to systems belonging to winter racing organizations," Sherstobitoff said.
"It is clear that the attacks are ongoing and are likely to continue throughout the games. "What has not been determined yet is whether the hackers involved are doing it for a reputation or if their motives are greater."
