Following a massive hack of Microsoft Exchange Servers earlier this year, the FBI has executed a court-authorized removal of malicious web shells installed on vulnerable computers in the U.S. While the FBI did not remove any zero-day exploits or tools that hackers may have placed on systems via web shells, it is a step in securing the servers and preventing further unauthorized access.
Now, the FBI is going through the process of trying to alert server owners that their systems were accessed and fixed. Though fixing these email servers may have helped with national cybersecurity, accessing the network of a private user by a government organization raises privacy concerns.
