QSC21, VMDR Training and Exam

1 Reply

QSC21, VMDR Training and Exam. Hello everyone! On the one hand, because of the pandemic, we have become more distant from each other. We work mostly remotely from home. Traveling to a conference in another country has become much more difficult than it used to be. Now it is not only expensive. It has become much more difficult to obtain visas, there are restrictions related to vaccines, tests, quarantines, etc. And sometimes the borders are simply closed and it is impossible to get there.

On the other hand, we have become paradoxically closer to each other. Conferences have become much more online-oriented. And the main event of Qualys, QSC 21 Las Vegas, is now available to everyone with no delays or restrictions. This year, I not only watched the show, but also took VMDR training, passed the exam and received a certificate. I want to talk about this in this episode.

Conference

I will only state the main idea. Of course the way I understood it. Chris Krebs, former director of the Cybersecurity and Infrastructure Security Agency (CISA), btw not related to a security blogger Brian Krebs, started the conference by talking about attacks. There will only be more of them, and it will be more difficult to mitigate these attacks. Of course, if companies could be protected with prohibitive measures, that would be fine. But the problem is that in order for a company to be competitive, it must build the “permissive environment”. Especially in our COVID times.

Last Week’s Security News: Black Hat Pwnie Awards, iPhone Checks Photos, Evil Windows Print Server, Cisco VPN Routers Takeovers

Last Week’s Security News: Black Hat Pwnie Awards, iPhone Checks Photos, Evil Windows Print Server, Cisco VPN Routers Takeovers. Hello everyone! Last Week’s Security News, August 1 – August 8.

Black Hat Pwnie Awards

Last week was more quiet than normal with Black Hat USA and DEF CON security conferences. I would like to start with the Pwnie Awards, which are held annually at Black Hat. It’s like an Oscar or Tony in the information security world. Pwnie Awards recognizes both excellence and incompetence. And, in general, is a very respectable, adequate and fun event.

There were 10 nominations. I will note a few.

  • Firstly 2 nominations, which were received by the guys from Qualys.
    Best Privilege Escalation Bug: Baron Samedit, a 10-year-old exploit in sudo.
    Most Under-Hyped Research: 21Nails, 21 vulnerabilities in Exim, the Internet’s most popular mail server.
  • Best Server-Side Bug: Orange Tsai, for his Microsoft Exchange Server ProxyLogon attack surface discoveries.
  • Most Epic Fail: Microsoft, for their failure to fix PrintNightmare.
  • Best Song: The Ransomware Song by Forrest Brazeal

MaxPatrol VM: An Ambitious Vision for Vulnerability Management Transformation

Leave a reply

MaxPatrol VM: An Ambitious Vision for Vulnerability Management Transformation. In this episode, I would like to share my thoughts about the new Vulnerability Management product by Positive Technologies – MaxPatrol VM. It was presented on November 16th, at the Standoff365 online conference (full video in Russian). The presentation and concept of the product were very good. I really liked them. However, as it always happens on vendor’s events, some critical topics were not covered. So I also want to highlight them. I will try to be as objective as possible. Although it is difficult for me, since I have worked in the company for 6 years, and many of my good friends work there.

MaxPatrol VM

Positive Technologies is best known in the Russian Vulnerability Management market. The volume of the Russian VM market in 2019 is $40-46 million. The volume of the world market, according to IDC, is $1.2 billion. So the Russian market is ~3% of the world market. And 78% of it is occupied by Positive Technologies products: Maxpatrol 8 and XSpider. Disclaimer: all numbers are from the Maxpatrol VM presentation and I haven’t done fact checking. But in this case, the numbers are not so important.

Microsoft Patch Tuesday September 2020: Zerologon and other exploits, RCEs in SharePoint and Exchange

Microsoft Patch Tuesday September 2020: Zerologon and other exploits, RCEs in SharePoint and Exchange. I would like to start this post by talking about Microsoft vulnerabilities, which recently turned out to be much more serious than it seemed at first glance.

Older Vulnerabilities with exploits

“Zerologon” Netlogon RCE (CVE-2020-1472)

One of them is, of course, the Netlogon vulnerability from the August 2020 Patch Tuesday. It’s called “Zerologon”. I would not say that Vulnerability Management vendors completely ignored it. But none of them (well, maybe only ZDI) emphasized in their reports that this vulnerability would be a real disaster.

Microsoft Patch Tuesday May 2020: comments from VM vendors, promising stuff for phishing, troubles with SharePoint and lulz with Visual Studio

Leave a reply

Microsoft Patch Tuesday May 2020: comments from VM vendors, promising stuff for phishing, troubles with SharePoint and lulz with Visual Studio. This will be my third Microsoft Patch Tuesday report in video and audio format. And for the third time in a row, Microsoft has addressed over a hundred vulnerabilities. With my Microsoft Patch Tuesday parser, it was possible to generate a report almost on the same day. But, of course, it takes much more time to describe the vulnerabilities manually.

Microsoft Patch Tuesday May 2020
  • All vulnerabilities: 111
  • Critical: 16
  • Important: 95
  • Moderate: 0
  • Low: 0

Last time I complained that different VM vendors release completely different reports for Microsoft Patch Tuesday. This time I decided that it’s not a bug, but a feature. I upgraded my script to not only show vulnerabilities, but also show how these vulnerabilities were mentioned in the reports of various VM vendors (Tenable, Qualys, Rapid7 and ZDI). In my opinion, it seems pretty useful.

Microsoft Patch Tuesday April 2020: my classification script, confusing RCE in Adobe Type Manager and updates for older vulnerabilities

Microsoft Patch Tuesday April 2020: my classification script, confusing RCE in Adobe Type Manager and updates for older vulnerabilities. Making the reviews of Microsoft Patch Tuesday vulnerabilities should be an easy task. All vulnerability data is publicly available. Even better, dozens of reviews have already been written. Just read them, combine and post. Right?

Microsoft Patch Tuesday April 2020: my classification script, confusing RCE in Adobe Type Manager and updates for older vulnerabilities

Not really. In fact it is quite boring and annoying. It may be fun to write about vulnerabilities that were already used in some real attacks. But this is a very small part of all vulnerabilities. What about more than a hundred others? They are like “some vulnerability in some component may be used in some attack (or may be not)”. If you describe each of them, no one will read or listen this.

You must choose what to highlight. And when I am reading the reports from Tenable, Qualys and ZDI, I see that they choose very different groups of vulnerabilities, pretty much randomly.

My classification script

That’s why I created a script that takes Patch Tuesday CVE data from microsoft.com and visualizes it giving me helicopter view on what can be interesting there. With nice grouping by vulnerability type and product, with custom icons for vulnerability types, coloring based on severity, etc.

Vulnerability Management Product Comparisons (October 2019)

Leave a reply

Vulnerability Management Product Comparisons (October 2019). Here I combined two posts [1.2] from my telegram channel about comparisons of Vulnerability Management products that were recently published in October 2019. One of them was more marketing, published by Forrester, the other was more technical and published by Principled Technologies.

Vulnerability Management Product Comparisons (October 2019)

I had some questions for both of them. It’s also great that the Forrester report made Qualys, Tenable and Rapid7 leaders and Principled Technologies reviewed the Knowledge Bases of the same three vendors.

Let’s start with Forrester.
