Japanese hackers are increasingly hitting Korean websites in an attempt to raise the profile of their claims to the Dokdo islets in the East Sea, the body of water between the Korean Peninsula and the islands of Japan (known in Japan as the Sea of Japan).
Speaking to the Korean Times the Korean Information Security Agency (KISA) said that Japan-based hackers accounted for over 15 percent, or over 10 million cases, of foreign network attacks.
"It is true that hacking trials from Japan-based Internet protocol (IP) addresses doubled in April when Dokdo was a hot-button issue between Seoul and Tokyo," said Kim Woo-han, chief manager of the KISA-affiliated Korea Internet Security Center.
The islets became a hot topic when Japan renewed its claim to them, calling February 22 "Takeshima Day", the Japanese name for the islands.
In April SC reported Chinese activists hit the Japanese Defense Agency has been hit with a flood of data causing users problems accessing the internet. The attack was in response to Japanese history texts that glossed over Japan's brutal warring past.
