@Jafar_Hussain,

Check the Threat Vault at the link below for Morti and there's already two antivirus signatures for MortiAgent and a WildFire signature. If you don't find that suitable defense you'll need to look into creating your own custom threat signature.

 

Custom Threat Signature

Threat Vault

@BPry 

Thanks for the information.

I was unable to find MortiAgent in the PAN threat vault

It is mandatory to create a custom signature for Mortiagent malware.

I have gone through the documents which you provided. if i will create a customer signature what is the threat id we need to use.

@Jafar_Hussain,

The threat ID you select doesn't matter, as long as it's within the available range. Some people make enough to actually create a format for numbering their custom IDs, others don't follow one and simply increment with each entry.

 

@BPry 

Thank you for the information, i will check this.

Hello,

Make sure your PAN objects are setup for AntiVirus, AntiSpyware, URL Filtering, WildFire, and DNS Sink hole. Then make sure they are applied to all inbound/outbound policies so the traffic is inspected. Also make sure your PAN has the latest Dynamic signatures.

 

Having the PAN setup for this is a great way to dynamically block malicious traffic. Along with your other products, i.e. desktop antivirus, etc.

Apart from this. it is a mandatory to create a custom signature?

Hello,

If you have all the other security features turned on and dynamic updates working and up to date. I would say you are good, however check the endpoint AV and make sure its working and maybe even run a full scan.

Thank you for the valuable information.

I got the instruction from the gov. i need to create a custom signature for Mortiagent. They have sent some files.

In the files, there is some IOC's:-

1 - Host base indicator( Which is mentioned some MD5 and SHA values)

2 - Network base indicator( Which is mentioned in some IP address list).

 

To create a custom signature which pattern and references i need to choose ? below is the snort rule:-

alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:" MoriAgent Beacon HTTP Request"; content:"/Index.php?i="; depth:200; content:"&t="; within:64; content:"HTTP/1.1"; within:64; content:"Content-Type: application/json"; within:32; content:"Content-Length: 0"; within:90; threshold:type limit,track by_src,count

1,seconds 120; sid:1000001; rev:001;)

 

- For the IP address, i need to create an EDL to block all the IP's?

 

Thank you in advance.

 

Hello,

If its a 'White' IOC notice, I wouldnt worry about it but I guess a EDL or a special policy with a block for those IP's would do.
