G7 governments are preparing exercises for cyber-attacks powered by artificial intelligence where saving the financial system may require shutting down some of its services. The agreement was announced by the Japanese Minister of Finance, Satsuki Katayama. Governments face difficult choices: continue services on a network that can no longer be trusted, or cut off communications along with legitimate operations. Japan's Internet group GMO has already asked Onamae Desktop Cloud customers to turn off their computers and disconnect them from the Internet. The company discovered foreign programs on the servers, leaked trading passwords and reported transactions unknown to customers. The group's shares fell 15.65% on October 26. The remote workplace, on which the clerk investing the trade, became a possible entry for his money. The account holder had to dispute the transaction made with his details. Banks also have a less obvious source of concern: the customer himself gives access to the AI assistant. Agent relationships are monitored by Morgan Stanley, Bank of America, J. P Morgan Wells Fargo. Morgan Stanley denies cases of unauthorized agents infiltrating its platforms. Even a voluntarily issued password leaves the bank with the task of distinguishing between the owner's instructions and the program's independent actions. Identity verification no longer answers the question of consent to a specific transfer. The South Korean attacks revealed another weakness. President Lee Jae-myung spoke on October 6 about signs of the use of artificial intelligence in leaks at 7 financial companies. According to the "Financial Times", intermediary services, in which the banks transferred customer information, were also affected. The money is not considered stolen then. A vulnerable external factor could endanger an organization whose main settlement center passed the test. Shared software adds scale. After discovering 2 critical PHP errors, the developers released fixes on October 21st.
