On March 15, Teikoku Databank announced its poll findings indicating a rapid rise in cyberattacks since mid-February. The poll covered the one-year period from March 2021, and some 30% of companies said that they were cyberattacked from mid-February through mid-March 2022, making this the period with the highest number of cyberattacks in the past year. There were also many cases where the cyberattack obstructed the company’s business activities.
The online poll was taken from March 11–14, 2022, and responses were received from 1,547 companies.
A full 36% of respondents said that they were hit by a cyberattack in the past year, including cases where the attack was not fully confirmed. Some 28% of them said that they were hit within the last month. Some 42% of companies said that they have never been hit by a cyberattack [in the history of their company]. The threat of cyberattacks is rising. A machinery manufacturer commented, “We have received a particularly high number of malicious emails after the Russian invasion of Ukraine.”
Of those companies reporting they had been cyberattacked in the past month, some reported damage. A precision parts manufacturer said that “customer information was leaked after our system was infected with a virus delivered in a malicious email.” An SME in construction said, “Dozens of emails were sent in the name of our company.”
Cyber Security Cloud, a security software company, surveyed over 15,000 sites in Japan, and the number of cyberattacks detected since mid-February was up as much as 25-fold from the average for the past three months.
