Editor’s note: CVE-2020-0601, unsurprisingly, has created a great deal of interest and concern. There is so much going on that we could not adequately provide a full accounting in a single blog post! This post focuses on detection of the vulnerability based on network logs, specifically Zeek as well as Endpoint. If you are collecting vulnerability scan data and need to keep an eye on your inventory of systems that are at risk, then check out Anthony Perez’s blog.

Software vulnerabilities are part of our lives in a digitalized world. If anything is certain, it’s that we will continue to see vulnerabilities in software code! Recently the CVE-2020-0601 vulnerability, also known as CurveBall or “Windows CryptoAPI Spoofing Vulnerability”, was discovered, reported by the NSA and made headlines. The NSA even shared a Cybersecurity Advisory on the topic. Anthony previously talked about it from a public sector and Vulnerability Scanner angle.

In December 2019, Citrix announced that their flagship product, Citrix Application Delivery Controller (ADC) and Gateway, had a vulnerability that would allow code execution to take place on affected devices without any authentication. This vulnerability (designated CVE-2019-19781) was severe - on a scale of 1 to 10 it was deemed a 9.8 meaning that an attacker able to exploit this vulnerability could do serious damage.

Last updated: 20th January, 9.45am. A critical Citrix vulnerability (CVE-2019-19781) is currently under mass exploitation. To detect if your organisation is compromised, Redscan has developed a script that will examine your host.

Honeypots are not a new idea. They have been part of the cybersecurity world for decades and have frequently gone in and out of “fashion” over that period. Recently, though, they have become an increasingly important part of vulnerability management. That’s for a couple of reasons. Honeypots offer real-world data on the types of threats that companies face, and they can be a powerful research tool in identifying specific threat vectors.

A zero-day (0-day) is an unpatched security vulnerability that is unknown to the software, hardware or firmware developer, and the exploit attackers use to take advantage of the security hole. In general, zero-day refers to two things: Zero day gets its name from the number of days that a patch has existed for the flaw: zero. Zero-day threats represent significant cybersecurity risk because they are unknown to the party who is responsible for patching the flaw and may already be being exploited.

The path is starting to get steeper now as we climb to ML2. It is time to start defining a vulnerability management program with objectives and goals. This program is expected to grow and evolve over time as the organization grows and evolves. Start by documenting what is in place now and what objections the organization is trying to reach. The stakeholders should come from multiple departments within the organization. For example, you will need buy-in from:

As we wind down 2019, it is a great time to think about your vulnerability management plans for the coming year. The five W’s can help guide our efforts as we resolve to improve our digital security for the coming new year. Vulnerability assessments are useful for detecting security issues within your environment. By identifying potential security weaknesses, these assessments help us to reduce the risk of a digital criminal infiltrating its systems.

What is vulnerability management? Why you need it? What components does an efficient vulnerability management tool have? You can find answers to these questions and much more in our article.

An exploit is a piece of software, data or sequence of commands that takes advantage of a vulnerability to cause unintended behavior or to gain unauthorized access to sensitive data. Once vulnerabilities are identified, they are posted on Common Vulnerabilities and Exposures (CVE). CVE is a free vulnerability dictionary designed to improve global cyber security and cyber resilience by creating a standardized identifier for a given vulnerability or exposure.
