Reputation Management AV+

Note

Reputation Management is available in ImunifyAV+ only.

Reputation Management is an analyzing and notifying tool intended to inform about websites blocking and blacklisting.

Choose Reputation Management in the main menu of the ImunifyAV+ user interface to get to the Reputation Management page.

Reputation Management allows to check if a domain registered on your server is safe or not based on the following reputation engines:

How does it work:

We get a list of domains periodically (via crontab)
Send it to the central Imunify server
Get results from it
Add bad domains to the list of Reputation Management

If a domain or an IP is blocked, then this information will be available in the table below. If a user’s website appears in this table, then it would be useful to send this link to the user. This instruction can help to solve problems with the domain.

At the top of the page (also in the main menu near Reputation Management item), ImunifyAV+ shows the number of affected domains. This number is a quantity of affected domains that exist on the server.

The table shows:

ID – domain owner username
URL – the affected domain link
Type – read more about types on the link (we still do not support THREAT_TYPE_UNSPECIFIED and POTENTIALLY_HARMFUL_APPLICATION).
Detection time – exact time when the Reputation Management has detected the domain


ImunifyAV → Reputation Management

Click link icon in the Action column to copy the URL to the clipboard.

Note

Reputation Management online and browser look may differ. This is because Google Safe Browsing has an issue described on github.

Hooks

Overview

Hooks are introduced as a script-based interface for various application events. This is a simple and effective way to automate ImunifyAV alerts and event processing. For example, an administrator can have ImunifyAV calling his own script when malicious files are detected or misconfigurations are detected and perform a custom processing or specific actions, for example, create a ticket. Hooks are available only via CLI.

Requirements

You can use any programming language to create a hook script
A hook script should be executable
For Native hooks, you should use Python 3.5 only

How to start using hooks

Start using hooks with three simple steps:

Create a script to handle an event (a hook handler):

you can use our scripts example as a template

Note

All results can be saved in a temporary file before handler invocation and then remove the file after the event is being processed

malware-cleanup
- subtype ( started | finished )
  - started - the event is generated when the malware cleanup process is started (for on-demand and background cleanup only, background auto-cleanup will be implemented later)
    - params[]
      - cleanup_id / string / unique id of the cleanup
      - started / int / unixtime when the cleanup was started
      - tmp_filename / string / path to a temporary file with a scanning report. The list is in the format of the following command: imunify-antivirus malware malicious list --by-scan-id=... --json . See malware-detected hook section for details.
      - total_files / int / number of files that were sent for cleanup
  - finished - the event is generated when the malware scanning process is finished (for on-demand and background cleanup only, background auto-cleanup will be implemented later)
    - params[]
      - cleanup_id / string / identifier of running cleanup
      - started / int / unixtime when cleanup started
      - total_files / int / number of files that were sent for cleanup
      - total_cleaned / int / number of files that were successfully cleaned
      - tmp_filename / string / path to a temporary file with a list of results.
      - errors[] / string / error messages if any occurred during cleanup
      - errors[] / string / error messages if any occurred during cleanup

Hooks CLI

The following CLI command is used to manage hooks:

imunify-antivirus hook [command] --event [event_name|all] [--path </path/to/hook_script>]

The following commands are supported:

add - register a new event handler
delete - unregister existing event handler
list - show existing event handlers
add-native - register a new native event handler

The third parameter event_name defines a particular event that invokes a registered handler as opposed to all keyword.
The fourth parameter /path/to/hook_script shall contain a valid path to a handler of the event, it shall be any executable or Python Native event handlers that agent will run upon a registered event.

Native

Native hook is a script written on Python 3.5 and allows to quickly process events. The Python file should contain only one method that customer would implement:

def im_hook(dict_param):
	….
	pass

where dict_param would hold the same data as JSON that non-Native hook will gate.

Log File

You can see all hook data in the log file. It is located at /var/log/imunify360/hook.log . When the event comes, the data is recorded to the log file in the following format:

timestamp event : id : started [native:] name :  subtype : script_path

native is prepended for the Native hook implementation
id is a unique ID for each event

Once the listener is done, the data is recorded to the log file in the following format:

timestamp event : id : done [native:] script_path [OK|ERROR:code]

In case of an error, you can see the error code you have specified.

Structure and examples of a hook script

Regular (non-native) hook:

#!/bin/bash

data=$(cat)

event=$(jq -r '.event' <<< ${data})
subtype=$(jq -r '.subtype' <<< ${data})

case ${event} in
    malware-scanning)
        case ${subtype} in
            started)
                # do stuff here
            ;;
            *)
                echo "Unhandled subtype: ${subtype}" 1>&2
                exit 1
        esac
        ;;
    *)
        echo "Unhandled event: ${event}/${subtype}" 1>&2
        exit 2
esac

Native hook:

def im_hook(dict_param):
   event = dict_param['event']
   subtype = dict_param['subtype']

   if event == 'malware-scanning':
       if subtype == 'started':
           # do stuff here
           pass
       elif subtype == 'finished':
           # do other stuff here
           pass
       else:
           raise Exception('Unhandled subtype {}'.format(subtype))
   else:
       raise Exception('Unhandled event {}'.format(event))
