Japanese government website becomes victim of Kilnet cyber attack

Cyberthreat.id – Russian-affiliated hacker group Kilnet has claimed responsibility for a series of cyber attacks against companies and 20 websites in four Japanese government ministries.

Notably, the country’s government is reportedly investigating whether the problems with the sites were caused by a denial of service (DDoS) attack, according to Chief Cabinet Secretary Hirokazu Matsuno, quoted from Infosecurity Magazine.

“We know that hacker groups [Killnet] suggested they were behind the attack, but at this time, we are still investigating the reasons for the failure, including the involvement of the group,” Matsuno said.

In fact, Japan’s digital agency also said that the e-Gov administrative portal was having problems logging into some services on Wednesday, but did not specify the reason. Japan’s digital minister also said that government websites were inaccessible on Tuesday evening, but they were restored the same day.

However, according to Sergei Shykevich, manager of the dangerous intelligence group at Check Point Software, it is likely that Kilnet was behind the attack.

“Kilnet’s reason for this attack was due to Japan’s support for Ukraine in the Russo-Ukrainian War, as well as the decades-long dispute over the Kuril Islands, over which both sides claim sovereignty,” Shykevich told InfoSecurity. told the magazine.

Shykevich also argues, cyber security experts say organizations in countries attacked by Kilnet should be aware of the risks, as the group uses a variety of tools to achieve its goals, including data Theft and disruptive attacks are included.

“Adopting a preventive first cyber security strategy will help reduce the likelihood of a cyber attack, such as establishing appropriate offline backups of critical business information, including worst-case recovery plans, and between critical and less critical areas. The division includes enterprise networks,” explains Shaykevich.

The alleged attack on a Japanese state website follows recent large-scale attacks by Kilnet on sites in Italy, Lithuania, Estonia, Poland and Norway.
