In the 10th edition of its ENISA Threat Landscape (ETL), the EU’s cybersecurity agency explicitly warns of increasing threats from hacking attacks on public sector entities.

Around a quarter of all security related incidents target administrative or government entities, the ENISA study reports – making the public sector nearly twice as much at risk as hosters and providers, who come in second at 13 %. More than ever, users should protect their networks – for example, with products from Greenbone.

The number one threat still are extortionate ransomware attacks, followed by malware and social engineering, e.g. where attackers try to obtain passwords from employees via telephone.

Geopolitics doesn’t stop at the public data center

However, things have changed in the last two years – not only the war in Ukraine ensured that “geopolitical aspects have a significantly greater influence” on threat scenarios, the ENISA authors write. Attacks are becoming more destructive, motivated by the armed conflict and are being flanked by targeted disinformation campaigns – which are increasingly directed against public institutions.

Businesses and government agencies, however, are worried by the fact that attackers have gained in skill level, aggressiveness and agility since 2021. The better organizations have adapted their cybersecurity programs and thus their defenses to the threat environment, the more they have forced attackers to adopt newer attack vectors, to the point of developing new, unknown zeroday exploits and more. At the same time, hacker groups are constantly becoming more agile, renaming themselves and continuously regrouping, further complicating attribution (matching an attack to individuals).

Progressive professionalization of attackers

As if that weren’t enough, the hacker-as-a-service model continues to gain traction; people are becoming more professionalized. Attacks are also increasingly targeting the supply chain, managed service providers and are becoming more and more, as they have been doing every year, especially in the upcoming reporting period – the phase at the end of a fiscal year when reports relevant to the stock exchange may have to be prepared.

What is new, however, according to ENISA, is the increase in hybrid threats, which are also fueled by state actors and software. The study specifically cites the spyware “Pegasus” developed by the Israeli government, as well as phishing and attacks on data infrastructures.

Machine learning and artificial intelligence

The professionalization of attacks has had a particularly fatal effect, because they have become much more sophisticated through the use of machine learning and artificial intelligence. For example, there are already bots that act as deep fakes, disrupt chains of command, and are also capable of disabling government institutions with masses of fake comments.

ENISA groups the typical attackers into four categories: State-sponsored, organized crime (cybercrime), commercial hackers (“hackers for hire”), and activists. The goal of all these attackers is usually unauthorized access to data and disruption of the availability of services (and in many cases the associated extortion of ransom money), they said.

Vulnerability Management protects

The only safe option that government agencies and companies have to counter these attacks is Vulnerability Management, which allows them to look at their own IT infrastructure from the outside, from the perspective of a potential attacker. This is the only way to identify and close security gaps before an attacker succeeds.

This is exactly where our Vulnerability Management products come in – as a hardware or virtual appliance or in the Greenbone Cloud Service. Greenbone develops an Open Source Vulnerability Management and allows users to detect vulnerabilities in their own network infrastructure within a few steps. Our products generate reports with concrete action instructions that you can implement immediately.

We work strictly according to German/European law and offer an Open Source solution. This means best data protection compliance and is thus guaranteed free of backdoors.

Greenbone: Many years of experience in the public sector

For many years, Greenbone has been offering customized products for the public sector, e.g. for requirements of higher security levels (classified, VS-NFD and higher).

Even networks that are physically separated from other networks can be scanned for vulnerabilities with Greenbone. Such areas separated by an “air gap” often occur in public authorities when network segments must be operated separately from the Internet and the rest of the public authority network due to a special need for protection. Greenbone’s products support strict airgap via special USB sticks, but also data diodes that allow traffic in one direction only.

No matter if you already have a frame contract with us or if you contact us for the first time, e.g. via the form on our website: We are happy to help you. Greenbone can look back on many years of experience with public authorities and is always ready to help you with words and deeds. Contact us!


The EuGH ruling known as “Schrems-II” on secure data exchange with the US has left a lot of legal uncertainty: Companies urgently need to adapt their contracts and a new solution is not in sight. It is time to switch to modern, data protection compliant and legally secure tools – such as the Greenbone Cloud Service for Vulnerability Management.

The “EU-US Privacy Shield” agreement, which attempted to regulate data protection in data transfers between the EU and the US (and other third countries), also failed to meet Europe’s requirements, its highest court ruled. In mid-July 2020, the European Court of Justice ECJ also declared the Privacy Shield invalid, following “Safe Harbor.”

Lack of legal certainty and renewed work

For many companies, this brought not only uncertainty, but also very concrete work: New standard contractual clauses (SCC) in accordance with the requirements of the EU Commission must be created. Time is pressing here: the EU’s “guardian of the treaties” will require new SCCs for old contracts as well from December 27, 2022.

Even more annoying, however, is that the future of transatlantic data processing also remains uncertain. According to experts, a decree by the U.S. president in October 2022 is likely to be just as short-lived as the predecessor regulations overturned by the ECJ. The legal areas are too different for a permanent, binding solution to be found. The only safe solution is to rely on legally secure products that comply with the GDPR from the outset.

Greenbone Cloud Service: GDPR-compliant Vulnerability Management already today

When it comes to vulnerability management, this is already possible today, quite simply with the Greenbone Cloud Service. It enables high-quality Vulnerability Management as a Service and allows users to detect vulnerabilities in their own network infrastructure (without installing virtual or hardware appliances) within a few steps and generates instructions for their remediation in the form of reports. Scan requests from the client network reach the scan clusters via cloud management, which do the core work and return the information for the reports more information here in the datasheet).

For both centrally managed networks and distributed environments that require high scalability, the Greenbone Cloud Service is perfect. The platform is ready to use within minutes without any local components. Users can start using the results immediately.

In addition, the Greenbone Cloud Service already ensures legal security and GDPR-compliant Vulnerability Management for all cloud customers today, because data processing takes place exclusively in German data centers, i.e. in the European legal area and within the scope of the GDPR. Data transfer of any kind to the USA or other third countries that cannot guarantee adequate data protection is thus excluded.

Try Greenbone Cloud Service for free

As a “trial”, the Greenbone Cloud Service is free of charge for 14 days. Users can try it out quickly, without special know-how directly in the web browser – during this time they can scan 2 external as well as 20 internal IP addresses. A direct upgrade to a valid subscription is possible at any time. The Greenbone Cloud Service Trial uses the daily updated Greenbone Enterprise Feed.

With its help, Greenbone automatically tests your IT network and all connected devices for more than 100,000 vulnerabilities and provides you with a daily updated, accurate status of the security situation in your company. Because the vulnerability check also provides you with information on the severity level at the same time, you can prioritize the identified vulnerabilities and the measures to be taken.

Vulnerability Management that looks at your IT infrastructure from the outside is indispensable in modern companies. With the perspective of a potential attacker, so to speak, you can ideally find every existing vulnerability in your IT infrastructure and take care of its elimination. Only those who know their vulnerabilities can implement security measures in a targeted manner.

ViPNet Client integrated into Greenbone Vulnerability Management

According to a report by ZDF Magazin Royale last Friday, there are growing fears that the VPN software “VIPNET”, from the company Protelion, a subsidiary of the Russian cybersecurity company O.A.O.Infotecs, could have security vulnerabilities.

It is feared that the software, which Protelion distributes, could allow the Russian secret service FSB (KGB) access to confidential information. Even though this claim is the subject of controversial debates between security experts and politicians, customers have approached us with the request to provide a test that can detect ViPNeT, especially on Windows computers.

Users of the Greenbone Enterprise Feed and the Greenbone Community Feed can verify the registration of InfoTeCS / Protelion ViPNet on Windows machines by an authenticated test.

Our customers can simply continue to use their Greenbone product, the test is already implemented in the feed. Those who do not yet have a Greenbone product yet, please use the link (check here) above.

Sustainable protection of your IT Networks

If you want to know which systems in your network are (still) vulnerable to vulnerabilities – including the ProxyNotShell vulnerability – our vulnerability management helps you. It is used in systems that must be patched or otherwise protected in any case. Depending on the type of systems and vulnerabilities, they can be found better or worse. The detection is also constantly improving and being updated. New gaps are found. Therefore, there may always be more systems with vulnerabilities in the network. Therefore, it is worthwhile to regularly update and scan all systems. The Greenbone vulnerability management offers corresponding automation functions for this.

Our vulnerability management offers the best protection

Vulnerability management is an indispensable part of IT security. It can find risks and provides valuable information on how to eliminate them. However, no single measure offers 100% security, not even vulnerability management.

We have developed a remote test for the Microsoft Exchange Server ProxyNotShell vulnerability GTSC2022.


Update from 2022-10-13: The vulnerability still exists after the October patchday on Tuesday. The blog post of Microsoft’s Security Response Center is continuously updated by the company, the last entry is from October 08.


The mentioned zero-day exploit in Microsoft Exchange Servers [GTSC2022] was published on September 28th by the cyber security company GTSC. After investigating a security incident, the security researchers discovered evidence of active exploitation of two vulnerabilities that can be used to compromise even fully patched systems.

The test (check here) extends our current vulnerability detection for Outlook Web Access (OWA) by checking whether Microsoft’s suggested remedies are in place. So far (beginning of October 2022), Microsoft only recommends workarounds. Microsoft Exchange users can use our test to ensure that the workaround instructions are implemented and active. Our customers can simply continue to use their Greenbone product, the test is already implemented in the feed. Those who do not yet have a Greenbone product yet, please use the link (check here) above.

Information on the technical background

Microsoft has published a post on its website [MSRC2022] describing that the vulnerabilities allow server-side request forgery (CVE-2022-41040) and remote code execution (CVE-2022-41082) if the attacker has access to PowerShell. However, this requires authenticated access to the vulnerable server (according to Microsoft, the Microsoft Exchange Servers 2013, 2016 and 2019).

The migration measures listed in the Microsoft blog (for example, disabling access to Powershell for unprivileged users) should be implemented as soon as possible by customers with on-premise solutions, as there is currently no known security update that fixes the vulnerability. According to Microsoft, users of Microsoft Exchange Online are not affected.

The severity of the vulnerability

In the Common Vulnerability Scoring System (CVSS), the vulnerabilities were rated as “high” and “medium” with a severity score of 8.8 and 6.3 out of 10, respectively. Since the vulnerabilities are already being actively exploited by attackers, there is also an increased risk of compromise for German institutions.

Greenbone is stepping up its commitment to open source and the community edition of its vulnerability management software. In addition to the open source code on Github, Greenbone now also provides pre-configured and tested Docker containers.

Official containers from the manufacturer itself

The Greenbone Community Containers are regularly built automatically and are also available for ARM and Raspberry Pi.

Björn Ricks, Senior Software Developer at Greenbone, sees this as a “big improvement for admins who just want to give Greenbone a try. Our official containers replace the many different Docker images that exist on the web with an official, always up-to-date, always-maintained version of Greenbone.”

Official Docker Container for Greenbone Community Edition

Hi Björn, what is your role at Greenbone?

Björn Ricks: One of my current tasks is to provide community container builds at Greenbone. Taking care of the community has always been a big concern of mine and for a long time I wanted to make sure that we also provide “official” Docker images of Greenbone. I’m very pleased that this has now worked out.

What is the benefit of the images for the community?

Björn Ricks: We make it much easier for administrators and users who want to test Greenbone. The installation now works completely independent of the operating system used: just download and run the Docker compose file that describes the services, open the browser and scan the local network. I think that’s a much lower barrier to entry, ideal even for anyone who doesn’t yet know the details and capabilities of our products.

Why does Greenbone now provide containers itself? There were already some on the net, weren’t there?

Björn Ricks: Yes, that’s right, but we found out that some people were unsure about the content, legitimacy and maintenance of these images. That’s why we decided to offer Docker images signed by us with verified and secured content.
All the container images existing on the network have different version status and even more so different quality grade. It is often impossible to tell from the outside whether an image is “any good” or not. Of course, you also have to trust the external authors and maintainers that they know what they are doing and that their images do not contain any additional security vulnerabilities. Only we, as producers of our own software, can guarantee that the published container images have the current version status and the desired quality grade.

Does Greenbone also plan to provide Docker images for its commercial product line, Greenbone Enterprise Appliances?

Björn Ricks: That depends on requests from our commercial customers. The Greenbone Community Edition includes access to the community feed with around 100,000 vulnerability tests. Our commercial feed contains even more tests, including those for many proprietary products that our customers use.

We have found that our customers are happy with our appliances, our virtual appliances, and our cloud solution – all of which qualify for use of the commercial feed subscription. However, this could change, and if it does, we will consider offering Docker containers to commercial customers.

How often are the images updated and what feed is included?

Björn Ricks: The images are built and published directly from the source code repositories. So they are always up to date and contain all patches. At the moment only the community feed is available for the images, but this might change in the future.

Where can I get the images and the documentation?

Björn Ricks: The Docker compose file for orchestrating the services is linked in the documentation, The Dockerfiles for building the Docker images can also be found on Github in the corresponding repositories, and are quite easy to download, for example: here.


Greenbone, the global leader in open source vulnerability management solutions, has launched a community portal for its user and developer community, making the extensive information available for community editions clearer and easier to access.

Who is the portal for?

At community.greenbone.net, vulnerability management experts invite users, developers and all IT professionals who are professionally involved in security and protection against hackers to browse forums, blogs, news and documentation and help shape the pages.

Central point of contact
“Our new Community Portal is the central place where users, experts, Greenbone employees and anyone else interested can meet and get up-to-the-minute information about the products, the company or new features,” explains Greenbone’s Community Manager DeeAnn Little: “We want the portal to be a home for the large, worldwide Greenbone community, with all the links and information anyone who works with our vulnerability management tools needs.”

What the new portal offers
For both Greenbone OpenVAS and the Greenbone Community Edition, you can find (under “Getting started“) numerous instructions on how to install and configure the community versions. In addition, there are news and updates, for example about the recently released Docker container releases of the Community Edition but also current figures about Greenbone installations on a world map and a completely revised forum with new categories and Blog.

For the community, with the community
“All this would not be possible without the numerous contributions from the Greenbone community, but at the same time this is only the first step,” explains Little: “In the future, we will also have our experts explain technical details and present new features here.

Greenbone invites the large community to give input and suggestions which topics are of relevance and interest for them Little explains:

“We welcome all input and all suggestions, ideas and ideas for improvement, which is exactly what the portal is here for. Send us your questions, any questions! What have we missed? What would you like to see? How can we make the portal, the forum and the new pages even better? What topics would you like to see – what should we report on?” You can leave your statement here, we will be glad to reveive it.

Greenbone Community Forum in a new look

Greenbone has also integrated the popular User Forum into the Community Portal. With the new look, it will continue to provide users of Greenbone’s software – regardless of their technical background – with a platform for ideas, mutual help, but also feedback.

“The forum is a place where users can meet and help each other as equals – it’s a place of exchange where we can always learn, too,” Little explains. “Whether it’s a beginner’s question, more in-depth howtos, or getting started guides, many a user will find help from experienced users in the forum, even in exotic setups.”

Greenbone, a world leader in open source vulnerability management software, has released its latest scanner, Notus.

“With Notus, a milestone for the performance of extensive comparisons of software versions has been created in recent years,” explains CIO Elmar Geese.

With Notus, Greenbone is also responding to customer requests for better performance in version checks. Whether a security vulnerability is dangerous for a company depends mainly on the installed software versions and their patch level. In very many cases, a vulnerability scanner must therefore match a large number of software versions and detect combinations of these. As the complexity of the setups increases, this test becomes more and more extensive. However, because the overall result of the scan also depends heavily on this data collection, Notus will enable such scans much faster than any of its predecessors.

Faster thanks to JSON

“The scanner rattles off the relevant servers and captures software running there. For the actual scan, it essentially only gets the info about affected and fixed packages,” explains Björn Ricks, Senior Software Developer at Greenbone. “With the previously used scanner and its predecessors, we usually had to start a separate process per version check, meaning a separate manually created script. Generating these scripts automatically is time-consuming.” Notus, on the other hand, only loads the data it needs from JSON files. Ricks sums it up, “Notus is significantly more efficient, requires fewer processes, less overhead, less memory, …”

CIO Geese then also declares the Notus scanner to be a “milestone for our users, it improves the performance significantly. Our well-known high detection quality as well as performance, central goals of our product strategy, will be optimally supported by the new scanner.”

Notus, Greenbone and OpenVAS

The Notus project consists of two parts: a Notus generator, which creates the JSON files containing information about vulnerable RPM/Debian packages, and the Notus scanner, which loads these JSON files and interprets the information from them.

OpenVAS, the Open Vulnerability Assessment System, was created in 2005, when the development team of the Nessus vulnerability scanner decided to stop working under open source licenses and move to a proprietary business model.

Since 2008, Greenbone has been providing professional vulnerability scanning support. For this purpose, Greenbone took over the further development of OpenVAS, added several software components and thus transformed OpenVAS into a comprehensive vulnerability management solution that still carries the values of free software. The first appliances came onto the market in spring 2010.

Microsoft Office has released patches for the Follina vulnerability CVE-2022-30190 (Follina) with the June 14, 2022 Windows Security Update. Appropriate vulnerability tests have been implemented in the Greenbone Enterprise Feed and the Greenbone Community Feed, allowing you to test your network for the vulnerability and take protective measures using the patches. Read more information about the latest Follina update here.

The vendor refers to the following security updates to close the vulnerability:

  • KB5014678: Windows Server 2022
  • KB5014697: Windows 11
  • KB5014699: Windows 10 Version 20H2 – 21H2, Windows Server 20H2
  • KB5014692: Windows 10 Version 1809 (IoT), Windows Server 2019
  • KB5014702: Windows 10 1607 (LTSC), Windows Server 2016
  • KB5014710: Windows 10 1507 (RTM, LTSC)
  • KB5014738: Monthly Rollup Windows Server 2012 R2, Windows RT 8.1, Windows 8.1
  • KB5014746: Security only Windows Server 2012 R2, Windows RT 8.1, Windows 8.1
  • KB5014747: Monthly Rollup Windows Server 2012
  • KB5014741: Security only Windows Server 2012
  • KB5014748: Monthly Rollup Windows Server 2008 R2, Windows 7 SP1
  • KB5014742: Security only Windows Server 2008 R2, Windows 7 SP1

This means that security updates are available for all versions of Windows Server and Client that are still in support. The vulnerability is rated as “important”, which means that users should install the updates promptly to close the gap.
Microsoft said, “The update for this vulnerability is included in the June 2022 Windows Cumulative Updates, and Microsoft strongly recommends that all customers install the updates to fully protect themselves from the vulnerability. Customers whose systems are configured to receive automatic updates do not need to perform any further actions.”

Installing the June 14 patches is all the more important because attackers and security professionals have already found several ways to exploit the vulnerability, but Microsoft has so far only offered workarounds (see also our blog article).
Greenbone has integrated corresponding vulnerability tests into the Greenbone Community Feed and the Greenbone Enterprise Feed and thus offers the possibility to test the network for this vulnerability and to take protective measures if necessary or to use the new Microsoft patches.

Once again, a flaw has surfaced in Microsoft Office that allows attackers to remotely execute malicious code on the systems of attacked users using manipulated documents. Known as Follina, CVE-2022-30190 has been known for years, but Microsoft has not fixed it to date. Greenbone has added an appropriate vulnerability test to their feeds to detect the new Follina vulnerability in Microsoft Office.

Follina Requires Immediate Action

The CVE named “Follina” is critical and requires immediate action: just opening Microsoft Word documents can give attackers access to your resources. Because a flaw in Microsoft Office allows attackers to download templates from the Internet via ms-msdt:-URI handler at the first click, attackers can create manipulated documents that, in the worst case, can take over entire client systems or spy on credentials.

According to Microsoft, the “protected view” offers protection. However, because users can deactivate this with just one click, the US manufacturer advises deactivating the entire URL handler via a registry entry. As of today, all Office versions seem to be affected.

Greenbone Enterprise Feed Helps and Protects

The Greenbone Enterprise Feed and the Greenbone Community Feed now contain an authenticated check for Microsoft’s proposed workaround, helping you to protect yourself from the impact of the vulnerability. Our development team is monitoring the release of Microsoft patches and recommendations for further coverage. We will inform about updates here on the blog.

Securing IT Networks for the Long Term

If you want to know which systems in your network are (still) vulnerable to vulnerabilities – including the critical vulnerability associated with CVE-2022-30190– our vulnerability management helps you. It applies to systems that definitely need to be patched or otherwise protected. Depending on the type of systems and vulnerability, they can be found better or worse. Detection is also constantly improving and being updated. New gaps are found. Therefore, there may always be more systems with vulnerabilities in the network. Thus, it is worthwhile to regularly update and scan all systems. For this purpose, Greenbone’s vulnerability management offers appropriate automation functions.

Vulnerability management is an indispensable part of IT security. It can find risks and provides valuable information on how to eliminate them. However, no single measure, including vulnerability management, offers 100 % security. To make a system secure, many systems are used, which in their entirety should provide the best possible security.

Greenbone is now a TISAX participant and its Information Security Management System (ISMS) and data protection processes are certified within the German automotive industry’s TISAX scheme. “We have taken this step as an effort in providing the best possible protection of sensitive and confidential information for our customers, as the next logical step after being successfully certified for worldwide accepted international industry standards like ISO 27001 and ISO 9001.” – Dr. Jan-Oliver Wagner, CEO of Greenbone. The results are available on the ENX portal using the Scope ID S3LW9L and the Assessment ID A1P7V9. TISAX and TISAX results are not intended for general public.

TISAX, the “Trusted Information Security Assessment Exchange”, is a mechanism for checking and exchanging test results according to industry-specific standards. Originally created as a system for the exchange of standardized test results in the automotive industry, it is optimized for the risk assessment of suppliers. Therefore, TISAX is being developed and governed by the ENX Association and published by the German Association of the Automotive Industry (VDA). Its focus lies on secure information processing between business partners, protection of prototypes and data protection in accordance with the EU’s General Data Protection Regulation (GDPR) for potential deals between car manufacturers and their service providers or suppliers.

As a crucial part of a secure supply chain, TISAX is a standard for Information Security Management Systems (ISMS), originally derived from the ISO/IEC 27001 standard in 2017, but has since diverged. For the automotive industry, TISAX brings standardization, quality assurance and guarantees information security measures are assessed by audit providers in accordance with the VDA standards. Audits according to TISAX, especially for service providers and suppliers, are carried out by so-called “TISAX audit service providers” and come with three levels of maturity an overview of which you can find in the TISAX Participant Handbook and on websites of certification providers like Adacor (German only).

Greenbone’s certifications increase our products’ value for our customers, not just by saving time and money, but also by proving our outstanding security level and high standards. Elmar Geese, CIO at Greenbone: “With TISAX, we document our independently audited security status. Customers do not need to do individual assessments, work with lengthy questionnaires or all the other things needed in a bottom-up audit. We guarantee that we meet their security requirements.”

Therefore, Greenbone follows the question catalogue of information security of the German Association of the Automotive Industry (VDA ISA). The assessment was conducted by an audit provider. The result is exclusively retrievable via the ENX portal (Scope ID: S3LW9L, Assessment ID: A1P7V9).
