Carbon Blacking your sensitive data it’s what the agents normally do

But usually without such consequences. In this situation with Carbon Black, I am most interested in the actual reasons of all this media noise. From what point business as usual becomes a scandal. Ok, when you see Carbon Black customer’s private files in public access at Virus Total it’s a 100% epic fail. But what about other options.

  1. Agent makes file analysis by himself on user’s host. It’s probably ok. Some paranoid person, like me, may say that it’s possible that data may leak during the update process, like in case of M.E.Doc. But it probably can be detected it in traffic somehow.
  2. Agent sends file to the vendor’s cloud for further analysis in some private multiscanner. Vendor will have copy of your private data. What if this data will leak? Are you sure that vendor will bear responsibility for this?
  3. Agent sends file to vendor’s cloud, vendor than sends it to some third-party for analysis. Are you sure vendors that you use doesn’t do this? How can you investigate this? What will be your next actions if you figure out that they do it without your permission?
  4. Agent sends file to the vendor’s cloud, vendor then sends it to some third-party for analysis, third-party opens access to this file for a wide range of people.

Downloading entire Vulners.com database in 5 minutes

Today I once again would like to talk about Vulners.com and why, in my opinion, it is the best vulnerability database that exist nowadays and a real game-changer.

The main thing is transparency. Using Vulners you not only can search for security content (see “Vulners – Google for hacker“), but download freely all available content from the database for your own offline analysis. And more than this, you can even see how Vulners actually works and evaluate how fresh and full the content is.

Vulners collections

Why you may need to download full security content database? For example, you may want to create something like vulnerability quadrants.

Petya the Great and why *they* don’t patch vulnerabilities

I really like this. Just imagine. Quiet, routine, everyday Vulnerability Management process in organizations: scanning-patching, scanning-patching, scanning-patching… And then. Suddenly! PEEETYYA!!!

And at very same moment everything changes. People from different companies start to communicate with each other actively, reverse this new malware, share the data, write and share tools for detection and recovery. Security professional is a friend, a brother and a source of useful information for security professional. Real movement! Real community! =)

Petya ransomware

For example, my friends from Vulners.com created pretty popular gist about Petya (petrWrap, notPetya, GoldenEye) and updated in real time for several hours.

Vulners Petya gist

My former colleagues from Positive Technologies released detailed technical review of this ransomware (in Russian) few hours since the outbreak started, at 01:00 am . They also found a local kill switch, and probably were the first one. Simultaneously with Amit Serper from Cybereason.

Vulners Cloud Agents for Vulnerability Management

A very good news! Vulners Team is ready to present complete functionality for vulnerability audit. And it’s not just an Audit API that you have to use somehow in your own scripts, but an enterprise ready product, like agent-based vulnerability scanning in Qualys and Tenable.

IP Summary

You can try it for free. Let’s see how to do it. For example we have a CentOS 7 server and we want to see vulnerabilities of this host in Vulners.

getsploit from Vulners.com

Kirill Isox Ermakov, the founder of Vulners, has recently presented a new open-source tool for searching and downloading exploits – getsploit.

Let’s say we want to pentest some WordPress blog. For example, this website avleonov.com. We can get WordPress version simply using curl:

$ curl -s https://avleonov.com | grep "generator"
<meta name="generator" content="WordPress 4.7.1" />

Ok, let’s get some sploits using this version:

$ sudo apt-get install git
$ git clone https://github.com/vulnersCom/getsploit
Cloning into 'getsploit'...
remote: Counting objects: 32, done.
remote: Compressing objects: 100% (21/21), done.
remote: Total 32 (delta 13), reused 30 (delta 11), pack-reused 0
Unpacking objects: 100% (32/32), done.
Checking connectivity... done.
$ cd getsploit/
$ ./getsploit.py "title:WordPress AND title:4.7.1"

getsploit

As you can see on the screen shot, getsploit makes a search request to vulners.com: bulletinFamily:exploit AND title:WordPress AND title:4.7.1 and matches objects in Immunity Canvas, DSquare Exploit Pack, Exploit-DB, Metasploit, Packet Storm, Malware exploit database, SAINTexploit™, seebug.org, Vulnerability Lab, 0day.today and Zero Science Lab.
