SOLVED cpanel login after AnonmousFox hack

123Host · Jan 23, 2020

After an attack by AnonymousFox, with a lot of effort, I have regained control of the server.

If I try to login to cpanel directly from WHMCS I get in no worries.

However if I try to login from the login page it fails with

Code:

A network error occurred during your login request. Please try again. If this condition persists, contact your network service provider.

the log /usr/local/cpanel/logs/error_log shows

Code:

    cpsrvd 3270daefd1ff: Failed to lookup the password file entry for the user âfoxâ

    [2020-01-23 18:08:45 +1000] info [cpaneld] Internal Server Error: "POST /login/?login_only=1 HTTP/1.1" 500 Error ID 3270daefd1ff

somewhere, no matter which user name I try, it seems to be attempting to get in as the user "fox"

I can't find anything in /etc/passwd that would cause this, all users seem to be there.

Any ideas on what is happening here and how to solve it?

123Host · Jan 23, 2020

I just found /var/cpanel/pw.cache/2:1391

the content is

{"VERSION":"1.01","cachetime":1579644017,"contents":["fox","$6$BOdRNoFC$XcYWiJ.DIfoGxh214qK1GrQtnMS2j/6gcY5P5oBu7q.0Q3rAUn4nNR2gARMmxTv/3No1nJ.LJ2S/OP0G9js/81","1391","1392","","","","/home/fox","/bin/bash","7","18282",1579644017,1579691683],"hcachetime":1579691683}

there is no directory /home/fox

OK...this may help someone else down the track. A lot of grep-ing and I eventually discovered /var/cpanel/resellers had a single line "fox:all"

Removing that line gave me full access again.

Do you use wordpress by any chance.
Keen to know what this hack is I came across a number of references to wordpress,

123Host · Jan 23, 2020

I am pretty certain it was a wordpress hack. Stupid me, I had a wordpres site on the same account as WHMCS so once they got in via WP they got into WHMCS and ended up with root access. WHMCS is now isolated.

It has been a very painful 24 hours but looks like it is all over apart from cleaning up as the Imunify360 scan finds infected files.

I'm glad you were able to get this resolved and thanks for posting the details here, as it will help others.

Thanks!

Hi everybody. Is there any useful link you guys can provide on how to prevent anonymousfox from breaking in? If it enters by injecting executable files thru vulnerable WordPress plugins, it does mean that cPanel have a vulnerability allowing injected files to get root access.
It is exploiting a bug in cPanel? or is there any current WHM configuration you can enforce to prevent that?

Thanks in advance

cPanelLauren · Sep 7, 2020

The anonymousfox vulnerability, caused by running vulnerable scripts on a cPanel account does not allow for root access @kentbrockman
Allowing vulnerable content on the server which in turn allows a way for an attacker to obtain access to the cPanel password reset does not constitute a bug.

What ultimately should be done here is remove the vulnerable content. You can also disable password resets for cPanel accounts to eliminate the ability for an attacker taking advantage of a vulnerable script to be able to reset the contact email and in turn reset the password, but if you don't get rid of the vulnerability they can continue to manipulate data in other ways. The issue needs to be resolved at the root of it, addressing symptoms of an issue will only get you so far.

Thanks Lauren. I know you must attack the root causes, but in a shared scenario with hundreds to thousands of websites spread across lots of servers, you obviously cannot be fully aware of what every customer upload or if security measures are in place.

I will disable password recovery and that should help a lot, yes. Thanks for the tip, that's the kind of idea I was looking for!

Looks like this Anonymousfox hack has hit us too. Not sure how it started but we've been battling it with the help of our provider for a while. Constantly changing the password didn't help.

Thanks for the clue to look up .contactemail file for the email address. We've also turned off password recovery. However, they continue to still login.

So far only one account is left that keeps getting hacked into. Today we've tried turning on 2FA just for that account. AND disable File Manager for all accounts.

Imunity360 has been a lifesaver to immediately deal with the PHP uploads.

I guess we all here are tired of this AnonymousFox thing. Well, I want to share what's working for us. Implement it and this will be a shot in the knees for this virus.

1) Disable password reset.
2) On WHM list your accounts sorted by contact email, and try to determine if non-sensical addresses are present. Double check and fix what you consider wrong, as they may be already modified.
3) On Apache Configuration, enable Apache Symlink Protection (beware: you need FollowSymlinks and SymLinksIfOwnerMatch active first).
4) On Apache Configuration > Include Editor > Post VirtualHost Include > All Versions, add the below sequence, which are the iThemes htaccess filters, which will stop the most common forms of virus and backdoors with a shot in their feet.
5) Run Imunify AV, even the free version is enough, in all of your accounts, with RapidScan and Binary (ELF) malware detection both enabled, and delete/clean infected files.

These are the htaccess filters mentioned in step 4:

Sorry, it's in spanish my native locale.
Feel free to use it all or pick segments of interest. The most important parts are: blockage of XMLRPC and remote PHP execution of files within plugins/themes/uploads.

Hope this help others to stop this and other virii.
Fixes and improvements are more than welcomed.

Good luck people.

Sorry, it's in spanish my native locale.
Feel free to use it all or pick segments of interest. The most important parts are: blockage of XMLRPC and remote PHP execution of files within plugins/themes/uploads.

Hope this help others to stop this and other virii.
Fixes and improvements are more than welcomed.

Good luck people.

I guess we all here are tired of this AnonymousFox thing. Well, I want to share what's working for us. Implement it and this will be a shot in the knees for this virus.

1) Disable password reset.
2) On WHM list your accounts sorted by contact email, and try to determine if non-sensical addresses are present. Double check and fix what you consider wrong, as they may be already modified.
3) On Apache Configuration, enable Apache Symlink Protection (beware: you need FollowSymlinks and SymLinksIfOwnerMatch active first).
4) On Apache Configuration > Include Editor > Post VirtualHost Include > All Versions, add the below sequence, which are the iThemes htaccess filters, which will stop the most common forms of virus and backdoors with a shot in their feet.
5) Run Imunify AV, even the free version is enough, in all of your accounts, with RapidScan and Binary (ELF) malware detection both enabled, and delete/clean infected files.

These are the htaccess filters mentioned in step 4:

Sorry, it's in spanish my native locale.
Feel free to use it all or pick segments of interest. The most important parts are: blockage of XMLRPC and remote PHP execution of files within plugins/themes/uploads.

Hope this help others to stop this and other virii.
Fixes and improvements are more than welcomed.

Good luck people.

I think this is awesome however I have some concerns.

On shared hosting please note blocking below may cause issues due to customers using these SEO tools for seo optimization

RewriteCond %{HTTP_USER_AGENT} "^SemrushBot" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "^AhrefsBot" [NC,OR]

Blocking PetalBot is an awesome addition as it causes high load now adays.

So edit or change what is required. I will be testing this with one client for now and see if the customer is happy. Thanks for the contribution.

Yes I know about concerns regarding Semrush and Ahrefs, but I particularly DON'T CARE. If some customer open a ticket because those service cannot scan their sites, I can move that cPanel to a server where those are specifically allowed.

And in the case a customer complain about xmlrpc.php being blocked, I recommend adding an override to their .htaccess so it is allowed again:

Apache config:

# Allow XML-RPC back again
<files xmlrpc.php>
    <IfModule mod_authz_core.c>
        Require all granted
    </IfModule>
    <IfModule !mod_authz_core.c>
        Order allow,deny
        Allow from all
    </IfModule>
</files>
# Allow XML-RPC back again

Hi Kent, How can I contact you privately? because I need to speak in Spanish with you

Go through my profile details here and you will find my website and the contact information is there. Just follow the breadcrumbs ;-)

I have the hack in one server wit cpanel

I have disabled password restore via email, but still creating new mail accounts with smtpfox-random

I see some php files into public_html folder, and .htaccess modified.

Also, I check in /tmp dir is creating some php files; actually I have a crontab every second with delete all files in /tmp , but its not the solution, obviously.

I check users crontab at /var/log/cron but I don't see nothing

Have you modified all the passwords? You should change cPanel/FTP passwords, also the contact email of compromised accounts.
WordPress sites are bots' targets of choice, so change admin users' passwords there too.
Also, fortify WP installs by blocking remote execution of PHP in uploads/plugins/themes folders.
