Wazuh active response with VirusTotal is not working - wazuh

Question

Wanted to integrate with VirusTotal and Yara but it seems like active response doesn't work as expected by following the steps in the link below:
https://documentation.wazuh.com/current/user-manual/capabilities/active-response/ar-use-cases/removing-malware.html
After adding/downloading eicar.com in /root directory, and read ossec.log, I get the following output:

Answer 1

About VirusTotal
I just followed the documentation and it worked well for me in Wazuh Manager 4.3.4 and a Wazuh Agent of the same version.
I got those same messages in /var/ossec/logs/ossec.log of the Wazuh Agent, those appear when the files do not exist or the proper permissions are not assigned, those files were replaced already in 4.2 but still show up in the log, since you are trying to use the script from the documentation then do not worry about those messages.
If you check under /var/ossec/logs/active-responses.log do you get any error?
What version of Wazuh Manager and Wazuh Agent are you using?
About Yara
It shouldn't be related to VirusTotal and probably deserves a different post, there is an issue open here but seems it is working, probably this comment helps you troubleshooting that one

Answer 2

The Active Response module is managed from the Wazuh Manager in /var/ossec/etc/ossec.conf, from here you can enable the response you need to execute using an <active response> configuration block that will use a "command" as a response. For example, if you are going to enable "remove-threat" as an Active Response on any agent that triggers the VirusTotal rule, you should have a <command> block and also an <active-response> block for that particular case, the same goes for any other AR case you may want to use.
<command>
<name>remove-threat</name>
<executable>remove-threat.sh</executable>
<timeout_allowed>no</timeout_allowed>
</command>
<active-response>
<disabled>no</disabled>
<command>remove-threat</command>
<location>local</location>
<rules_id>87105</rules_id>
</active-response>
The Response (script) needs to be present on each agent under /var/ossec/active-response/bin/. If you are only using the "remove-threat" Active Response, you should only have a single <active-response> block on the Manager's configuration file. Each <active-response> block within the Manager's "ossec.conf" must have a matching <command> block that is basically the response (script) the module is going to use. Perhaps you can share with us this configuration file so we can take a look.
Also, the following output from the Manager will be useful to see if the integration with Virustotal is being activated:
cat /var/ossec/logs/ossec.log | grep wazuh-integratord
I hope this helps,
