Japanese companies are on alert for possible cyber-attacks following the government's decision to impose economic sanctions on Russia.
Ukraine suffered massive cyber-attacks prior to Russia's military invasion of that country, and the Russian government is believed to have been involved. According to an analysis released Thursday by information security company Trend Micro Inc., the cyber-attacks that targeted Ukraine affected the websites of about 70 government organizations, including the Ukrainian Foreign Ministry, on Jan. 13-14.
On Feb. 1, attacks were confirmed in which individuals and organizations received emails containing viruses.
