Enable selective E-Mail notifications for events you want to be informed aboutД®-Mail notifications are a good tool to be informed about such kind of attacks. Configure those policies as selective and restrictive as possible. In addition to disallow the access for вЂњAll Other Users/GroupsвЂќ, you may also restrict the access for users and groups inside the firewall policies. We recommend you to disallow access to the SSL-VPN for groups that were not explicitly allowed on the mappings above. Ensure, that a no-access profile is enabled for вЂњAll other users/groupsвЂќДЄt the bottom of the table in the вЂњSSL-VPN SettingsвЂќ where the Authentication/Portal Mapping is configured, there is an option for вЂњAll Other Users/GroupsвЂќ. Please note: You may also consider to implement local-in policies to prevent the traffic from reaching the FortiOS in any way. There is a Fortinet KB that explains everything (please note the last part too). If your users only need access to the SSL VPN portal from a specific source address or range, you can limit the allowed source addresses to those addresses. Limit the count of failed login attepts until the user is bannedДЇortinet has a KB regarding the implementation of a login-limit for SSL VPN under Restrict the source IP address area DonвЂ™t forget to change the port on all VPN clients too. Using another port is an easy but effective measurement if an attacker is only probing the default port of an application. Change the listening Port for the SSL-VPN portal We recommend you to differentiate between user accouns that are allowed to access VPN solutions and administrative accounts that are only allowed to access the administrative interfaces. Ensure, that admin users have no access to the SSL-VPN portal With the third factor, the attacker needs access to additional information like the smartphone (in case of push token) or a 6 digit number (in case of mobile or hardware tokens). Two factor authentication prevents an attacker from being able to log in to an account only with username and password. Implement Two-factor authentication for all accounts

Passwords must have an age below 8 weeks.

Passwords must contain upper- and lowercase letters.

Passwords must contain special characters.

Passwords must have a minimum length of 12 characters.

This includes password rules like in this example:

How to minimize the attack surface Use strong passwords for all accounts (Have a look at our tipps below on how to minimize the attach surface)Дid you make similar observations? Did you come to another conclusion? Your comments regarding this events are very appreciated. In environments, where the basic rules of security are implemented properly, there is no chance that such an attack will be successfull.All the usernames that we were able to observe are users that are not existing or have no access to the SSL-VPN in most setups.

That is slowing down the whole process a lot.

There is not one user that is being attacked but there are plenty of them and they are being attached serially.

The attacks are being executed very slowly (5 вЂ“ 20 login tries per hour), so no performance problems are to expect.

Neither there is no strong need to block those вЂњvery basicвЂќ attack because this attack is not very sophisticated and should have no effect on a well secured setup.

We discussed a lot of possible solutions and came to the conclusion, that there is no simple way to block these attacks.

Only SSL-VPN Sites on Port 10443 are being attacked, Portals running on other ports like 443 are not (yet).

Only a few usernames are being tried: admin, administrador, administrator, user, vpn, vpnuser, aadmin, badmin, cadmin, dadmin вЂ¦ zadmin, and few more.

Not all FortiGates that are connected and reachable publicly over the internet are affected.

Almost every login try is coming from a different source IP to prevent a block.

A lot means around 5-20 events per hour.

A lot of failed login events are being logged.

Lets summarize what we have found out until today: Most of the administrators saw a rised number of the following log messages in the вЂњVPN Event LogвЂќ on the FortiGate / FortiAnalyzer.ДЄnd no, thereвЂ™s no spelling mistakes in the titleвЂ¦ ThatвЂ™s the way the log message is named: date= time=11:22:33 logid='0101039426' type='event' subtype='vpn' level='alert' vd='root' eventtime=1629710539 logdesc='SSL VPN login fail' action='ssl-login-fail' tunneltype='ssl-web' tunnelid=0 remip=11.22.33.44 user='administrador' group='N/A' dst_host='N/A' reason='sslvpn_login_permission_denied' msg='SSL user failed to logged in' Since last week, we observed a lot of failed SSL-VPN login events on various FortiGate setups.
