| Description |
|---|
| Unauthorized permissions of the /etc/hosts file can lead to the ability for a malicious actor to redirect traffic to servers of their choice. It is also possible to use the /etc/hosts file to block detection by security software by blocking the traffic to all the download or update servers of well-known security vendors. |
| ℹ️ Check |
|---|
| Check the mode of /etc/hosts using command: # ls -al /etc/hosts The above command should yield the following output: -rw-r----- 1 root system 993 Mar 11 07:04 /etc/hosts If the file has a mode more permissive than "0640", this is a finding. |
| ✔️ Fix |
|---|
| Change the mode of the file to 0640 using command: # chmod 0640 /etc/hosts |
