Regarding potentially unprecedented actions Reported With the help of a court order, the Federal Bureau of Investigation (FBI) has authorized in China to hack into the Microsoft Exchange mail server installed by the Hfnium Hafnium Group (Hfnium Hafnium Group).
According to reports, state-sponsored Chinese hackers used vulnerabilities in Microsoft Exchange to automatically install full-access backdoor programs on thousands of mail servers around the world. The March incident broke out in early March. The vulnerability was patched by Microsoft on Tuesday in February this year, but many servers have not yet been patched by the administrator, and the backdoor still needs to be manually deleted from the mail server that has crashed.
According to the current actions, the FBI has used the hacker’s own tools to remove the backdoor from the server, but it will only contact their owners afterwards to notify them of the incident and remind them of the need to install the update.
