Securities Accounts: Measures to Prevent Account Hacking Are Urgently Needed
There has been a sharp increase in crimes in which accounts opened with securities companies are hacked by unknown persons and stocks are traded without the account holders' knowledge. Individual investors must be feeling very uneasy.
With renewal of the Nippon Individual Savings Account (NISA) investment program in January last year, the base of individual investors has expanded. The securities industry must urgently implement measures to prevent accounts from being hacked. Law enforcement authorities must also devote their full efforts to cracking down on such crimes.
The Financial Services Agency has announced the extent of the damage caused by the online hacking of securities accounts and stock trades.
The number of cases of illegal trades was in the double digits in January and February but surged to 687 cases in March and 2,746 in April. A total of 3,505 cases were reported over the four-month period. This is a serious situation.
Incidents were confirmed at nine securities firms, including Rakuten Securities, Inc., SBI Securities Co. and Nomura Securities Co. The FSA said the amount of illegal trading in this way has exceeded ¥300 billion.
The method used to hack accounts involves first sending emails with titles such as 'Urgent/Important' to investors. Recipients are directed to websites imitating those of the securities companies mentioned in the emails, where they are then prompted to enter their ID and password, which are then stolen.
Criminal groups use the stolen IDs and passwords to take control of legitimate securities accounts. They are believed to purchase large quantities of stocks in China and Japan that are typically traded at low prices and low trading volumes. After inflating the stock prices, they then sell the stocks to profit from the increased prices. This is a malicious criminal act.
Investigative authorities should identify the sources of the emails, trace the flow of funds obtained through illegal means and uncover the full extent of the crimes.
Preventive measures by securities companies are also crucial. They have reportedly implemented safety measures such as requiring investors to enter one-time passwords sent to their smartphones when logging into their accounts. It is essential to thoroughly inform investors of these measures.
Investors should also confirm their own protective measures. It is important not to open links displayed in scam emails, but to instead access legitimate websites.
Securities companies have said that they would compensate damages of accounts affected by the incident to a certain extent. While their terms and conditions previously stated that damages incurred by cases of unauthorized access would not be compensated, they have revised their policy in response to the expanded scope of the damages.
Investors are growing increasingly anxious, and swift responses are required.
It is surely necessary for each major securities company to make efforts to provide appropriate information, such as holding individual press conferences, regarding the spate of incidents and their response measures.
The Japan Securities Dealers Association, an industry group of securities firms, has begun discussions on measures to prevent illegal accesses. It should come up with effective countermeasures.

China Hopes to Improve Japan Ties Amid Conflict with U.S.; Resumption of Japanese Seafood Imports Seen as Attempt to Boost Ties with Neighbors
The Yomiuri Shimbun Chief Cabinet Secretary Yoshimasa Hayashi, second from left, speaks at a meeting to expand exports of agricultural, forestry and fishery products at the Prime Minister's Office on Friday. Japan and China agreed to begin procedures to resume exports of Japanese marine products to China. Amid Beijing's conflict with Washington, China is hoping the move will improve bilateral ties with Japan. However, the resumption of exports of Japanese marine products will only apply to 37 prefectures, excluding Tokyo and nine other prefectures. The Japanese side will continue to seek the resumption of exports from these 10 prefectures as well as China's positive responses to other bilateral issues. 'This could be a big step forward in tackling various issues between Japan and China,' Foreign Minister Takeshi Iwaya said at a press conference on Friday. China imposed a total ban on imports of Japanese marine products in response to the release of treated water from Tokyo Electric Power Company Holdings, Inc.'s Fukushima No. 1 nuclear power plant into the ocean. The release began in August 2023. Beijing subsequently launched a campaign criticizing the release at international conferences and other venues, saying, 'The Pacific Ocean is not a sewer for Japan's 'nuclear-contaminated water.'' Perceiving China's move as a way to undermine Japan's position in the international community, the Japanese government focused on winning the understanding of various countries, including South Korea and Pacific island nations. Japan had urged China to withdraw the embargo while spreading the view that there was no scientific evidence to support Beijing's ban. Under the latest agreement, such documents as an inspection certificate for radioactive tritium will be required for the initial exports, but the export procedures are expected to be almost the same as before August 2023. 'It took time, but we were able to achieve results without making major concessions,' a senior Foreign Ministry official said. Since U.S. President Donald Trump began his second term in January, Chinese President Xi Jinping's government has been at odds with Washington over tariffs. It is thought that China's move to resume imports of Japanese marine products is part of efforts to quickly improve ties with neighboring countries. The Chinese side hopes to attract more investments by improving ties with Japan. In 2024, direct investment in China by foreign companies declined 60% compared to the previous year, the lowest level since 1992. At the same time, China is marking this year as 'the 80th anniversary of winning the war against Japan,' inflaming people's patriotism. Some believe China worked to quickly reach an agreement with Japan because it would become more difficult for Beijing to make moves that could be seen as making concessions to Japan as the date neared Sept. 3, which marks the anniversary of China winning the war against Japan. However, some on the Chinese side have made certain remarks that raise doubts about whether the country wants to improve relations with Japan. At a press conference on Friday, Lin Jian, a Chinese Foreign Ministry spokesman, referred to the treated water as 'nuclear-contaminated water.' As the Chinese government has criticized Japan, it is believed that China is slowly introducing measures to improve ties with Japan while considering public opinion at home. The decision not to include marine products from the 10 prefectures may be part of that effort. Chinese Premier Li Qiang is expected to visit Japan this year for a trilateral summit meeting between Japan, China and South Korea. Japan is to chair the summit. If realized, Prime Minister Shigeru Ishiba's first visit to China may also be considered. However, there are still many issues between Japan and China, including ensuring the safety of Japanese residents in China and China's violation of Japanese airspace with its aircraft flying near the Senkaku Islands in Okinawa Prefecture. Japan plans to cautiously explore ways to improve relations with China because the issue of economic security, with China in mind, is on the agenda for Japan-U.S. tariff negotiations. 'We will carefully move forward with our diplomacy with China one step at a time while comprehensively seeing how the U.S.-China conflict and the Japan-U.S. tariff negotiations will unfold,' said a Japanese government official.

Japan lender receives business improvement order following cover-up
The government's Tohoku Local Finance Bureau on Thursday issued a business improvement order to regional credit cooperative Iwaki Shinkumi Bank, partly for covering up fraudulent loans for many years. According to the bureau, former executives of the cooperative, including a former chairman, concealed for a long time fraudulent corporate loans, including through the accounts of depositors opened without their consent. The practice is believed to have started in 2004 or even earlier, according to the bureau and the Financial Services Agency. In addition, the lender, based in Iwaki, Fukushima Prefecture, let a former employee who committed embezzlement continue working as usual without taking disciplinary action. The employee later committed further embezzlement. The bureau said that corporate governance did not function due to the massive influence held by the former chairman. The bureau requested that Iwaki Shinkumi Bank submit a business improvement plan by June 30. It also ordered the cooperative to revise a special business plan drawn up in exchange for a public funds injection in 2012. On Thursday, Iwaki Shinkumi Bank said that its leader, Yohachi Honda, and other executives will resign to take responsibility. The lender had disclosed its misconducts in November 2024.
