In the previous hacker attack code-named Hafnium, hundreds of thousands of Microsoft Exchange servers worldwide were attacked, and a large number of small businesses and government departments were infected.
Microsoft’s security response department launched a message on the 23rd, stating that 92% of Exchange servers worldwide have fixed vulnerabilities or moved addresses, and 43% of servers have been improved last week.
The statistical data comes from the research organization RiskIQ, and the number of vulnerable Exchange servers in the world has dropped to 29,966.
Microsoft this month launched a diagnostic tool to help users determine whether the system is vulnerable to Hafnium attacks, and also released an emergency patch.
Security software company F-Secure recommends server operation and maintenance personnel to use tools to check the system to see if the server is being used by hackers.
