Japanese government websites hit by cyberattacks, Killnet suspected
Russian-affiliated hacking group Killnet has claimed responsibility for a series of cyberattacks against Japanese companies and 20 websites across four government departments.

However, according to Sergey Shykevich, head of the threat intelligence group at Check Point Software, it is likely that Killnet is behind these attacks.

“Disrupting the daily lives of citizens with attacks on government and organizational websites is a surefire way to embarrass the government and the people.”
Additionally, the cybersecurity expert said that organizations in countries attacked by Killnet must be alert to risks as the group uses various tools to achieve its goals, including data theft and disruptive attacks.
“Adopting a prevention-focused cybersecurity strategy will help reduce the likelihood of a cyberattack, such as preparing for proper offline backup of critical business information, including a recovery plan in case worst-case scenarios and segmentation between critical and less critical areas of the corporate network,” Shykevich explained.
The alleged attacks on Japanese state websites follow a recent large-scale attack by Killnet on sites in Italy, Lithuania, Estonia, Poland and Norway.
