Detectify Asset Inventory and Monitoring

Leave a reply

Detectify Asset Inventory and Monitoring. Continuing the topic about perimeter services. As I mentioned earlier, I don’t think that the external perimeter services should be considered as a fully functional replacement for custom Vulnerability Management processes. I would rather see their results as an additional feed showing the problems your current VM process has. Recently I tested the Detectify’s Asset Inventory (Monitoring) solution, which provides such feed by automatically detecting the issues with your second, third (and more) leveled domains and related web services.

Let say your organization has several second level web domains, over9000 third (and more) level domains, and you even don’t know for what services they are used. This is a normal situation for a large organization. So, you simply add yourorganization.com to Detectify, activate Asset Monitoring, and Detectify automatically discovers third (and more) level domains and related technologies: web services, CMS, JavaScript frameworks and libraries. “It provides thousands of fingerprints and hundreds of tests for stateless vulnerabilities such as code repository exposure for SVN or Git.” This is called fingerprinting.

Zbrunk search launcher and event types statistics

Leave a reply

Zbrunk search launcher and event types statistics. I also changed the priorities. Now I think it would be better not to integrate with Grafana, but to create own dashboards and GUI. And to begin with, I created a simple interface for Searching (and Deleting) events.

upd. 16.12.2019

A small update on Zbrunk. First of all, I created a new API call that returns a list of object types in the database and number of this types for a certain period of time. Without it, debugging was rather inconvenient. 

$ curl -k https://127.0.0.1:8088/services/searcher -d '{"get_types":"True", "search": {"time":{"from":"1471613579","to":"1471613580"}}, "output_mode": "json", "max_count":"10000000", "auth_token":"8DEE8A67-7700-4BA7-8CBF-4B917CE23512"}'

{"results": ["test_event"], "results_count": 1, "all_results_count": 0, "text": "Types found", "code": 0}

I also added some examples of working with Zbrunk http API from python3. Rewriting them from pure curl was not so trivial. ? Flask is rather moody, so I had to abandon the idea of making requests exactly the same as in Splunk. ? But the differences are cosmetic. It is now assumed that events will be passed to collector in valid json (not as a file with json events separated by ‘\n’). I also send all params of requests as json, not data. But for the compatibility reasons previous curl examples will also work. ?

Barapass console Password Manager

2 Replies

Barapass console Password Manager. I decided to publish my simple console Password Manager. I called it barapass (github). I’ve been using It for quite some time in Linux and in Windows (in WSL). Probably it will also work natively in Windows and MacOS with minimal fixes, but I haven’t tried it yet.

Why do people use password managers?

Well, with password manager it’s possible to avoid remembering passwords and make them arbitrarily complex and long. And no one will be able to brute force them. Of course, you can simply store passwords in text files, but password managers are better than this because:

  • no one will see your password over your shoulder;
  • if an attacker gains access to the files on your host, it won’t possible to read your passwords from the encrypted file or storage (well, ideally);
  • it’s easier to search for objects in the password manager and copy values from it.

I wanted something as simple as editing a text file with the key-value content. And I wanted it to be stored in a secure manner, and security could be easily checked, “simple and stupid”.

How to get the Organization Units (OU) and Hosts from Microsoft Active Directory using Python ldap3

How to get the Organization Units (OU) and Hosts from Microsoft Active Directory using Python ldap3. I recently figured out how to work with Microsoft Active Directory using Python 3. I wanted to get a hierarchy of Organizational Units (OUs) and all the network hosts associated with these OUs to search for possible anomalies. If you are not familiar with AD, here is a good thread about the difference between AD Group and OU.

It seems much easier to solve such tasks using PowerShell. But it will probably require a Windows server. So I leave this for the worst scenario. 🙂 There is also a PowerShell Core, which should support Linux, but I haven’t tried it yet. If you want to use Python, there is a choice from the native python ldap3 module and Python-ldap, which is a wrapper for the OpenLDAP client. I didn’t find any interesting high-level functions in Python-ldap and finally decided to use ldap3.

Kaspersky Security Center 11 API: getting information about hosts and installed products

4 Replies

Kaspersky Security Center 11 API: getting information about hosts and installed products. I spent a lot of time last week working with the new API of Kaspersky Security Center 11. KSC is the administration console for Kaspersky Endpoint Protection products. And it has some pretty interesting features besides the antivirus/antimalware, for example, vulnerability and patch management. So, the possible integrations with other security systems might be quite useful.

Kaspersky SC 11 openAPI

A fully functional API was firstly presented in this latest version of KSC. It’s is documented pretty well, but in some strange way. In fact, the documentation is one huge .chm file that lists the classes, methods of these classes and data structures with brief descriptions. It’s not a cookbook that gives a solution for the problem. In fact, you will need to guess which methods of which classes should be used to solve your particular task.

For the first task, I decided to export the versions of Kaspersky products installed on the hosts. It is useful to control the endpoint protection process: whether all the necessary agents and products were installed on the hosts or not (and why not).

How to make Email Bot service in Python

How to make Email Bot service in Python. First of all, why you may want to use such service? Despite the fact that currently there are so many different channels of communication (including various messaging apps), Email is still a default and universal way to do it.

  • Literally every enterprise service supports email notifications, even if it’s integration capabilities are rather limited. So, with Email Bot you can automatically process such notifications.
  • Email is good, simple, reliable and familiar way to communicate with humans. Send an email – get response. Everyone can do it. So, email bot can make basic routine operations, like organizing the external meetings, pretty much like a human secretary.
  • It’s easier to code Email bot than any other interface, and the code can be reused for other communication channels, for example messaging apps.

Open Positioner: my new project for tracking IT and security jobs

Open Positioner: my new project for tracking IT and security jobs. The idea of my new project is to retrieve the data from job-searching websites and provide better filtering, searching and visualization.

I think for the most people who read this, searching for a job in Internet is a pretty common activity. Even if you are not going to change job right now, it might be quite interesting to know what skills are currently the most valuable for your specialization and what is going on on the Global labor market.
