The dangerous reality of "Japan's medical system" targeted by cyber attacks

Preventing medical cyber terrorism is an urgent issue

The damage caused by ransomware in Japan is about 250 million yen, the second highest in the world!

Cyber-attacks against medical institutions that take advantage of the spread of the new coronavirus are increasing around the world.

In Japan, too, the 120-bed Handa Hospital in Tsurugi Town, Tokushima Prefecture, was attacked at the end of October last year, putting it in an unprecedented crisis. Also, in early December last year, it was reported that the Tokyo Metropolitan Government received information on cyberattacks targeting metropolitan hospitals and issued an emergency alert to all metropolitan hospitals. Countermeasures against medical cyber terrorism against hospitals are now an urgent issue. Meanwhile, there is a company that researches and develops new technology that can respond to "medical cyber terrorism" with a completely new methodology. It is “Scrumy Co., Ltd.” where “young geniuses” gather, including graduates from the University of Tokyo, Kyoto University, Waseda University, Keio University, Yale University, etc. Kento Sasano, the company's CEO, who graduated from Kyoto University's Faculty of Law and has conducted research to strengthen governance and information security at the University of Tokyo's Graduate School of Interdisciplinary Information Studies, has the following analysis. “In the case of the damage to Handa Hospital, I think it was probably a result of an indiscriminate attack targeting vulnerabilities in the system. It is said that there is a high possibility that the system that was found was not patched.This time the crime is the most active criminal group "LockBit 2.0" Ransomware. 's ransom means ransom, but by sending a virus into the computer system, it encrypts the data so that it can not be seen, and demands that you pay the ransom if you want it to be decrypted. ;2.0's modus operandi is double threats that if you don't pay the ransom, your data will be distributed to leak sites on the dark web.In some cases, your data was actually distributed. There is a dark site called "LEAKED DATA" for publicizing , where a countdown is displayed and it is a flow that mentally attacks general companies and hospitals like a time bomb.That's not all. There is also a market for selling ransomware 'ransomware-as-a-service' to other criminal groups, who then buy the ransomware and launch further attacks." ◆Damage amounted to approximately 250 million yen, ranking second in the world... Ransomware attack success rate of 95%! In fact, according to the 2020 edition data of "The Current State of Ransomware" by the research company Sophos, the amount of ransomware damage in Japan is about 250 million yen, the second highest in the world!
