LDAP Nom Nom is a recently discovered brute-force technique for enumerating valid usernames in Active Directory — anonymously and without leaving any log entries behind. It abuses LDAP Ping, a little-known mechanism in Active Directory normally used by computers to check whether a domain controller is alive. This blog post explains how LDAP Ping works and how adversaries can abuse it with LDAP Nom Nom.
SnakeYaml is a well-known YAML 1.1 parser and emitter for Java. Recently, a vulnerability — CVE-2022-1471 — was reported for this package. This vulnerability can lead to arbitrary code execution. The org.yaml:snakeyaml package is widely used in the Java ecosystem, in part because it is packaged by default with Spring Boot in the spring-boot-starter.
When the CrowdStrike Services team conducts a proactive security engagement, such as a Cybersecurity Maturity Assessment or Tabletop Exercise, it often uses CrowdStrike Falcon® Spotlight to identify what vulnerabilities exist in the environment. Unfortunately, this can be a disheartening experience, as many organizations we see have millions, even tens of millions, of unpatched vulnerabilities. It’s typical to see at least a quarter of those listed with a CVSS rating of Critical.
If I asked you what the common ways to exploit a cloud app for malicious purposes are, I bet your answer would probably be either to use it to distribute malicious content (such as malware or phishing pages), or to host the command and control (C2) infrastructure. In reality another frequent technique is the dead drop resolver, where a legitimate service is abused by threat actors to host the information related to the C2 infrastructure rather than the C2 infrastructure itself.
The JFrog Security Research team continuously monitors popular open-source software (OSS) repositories with our automated tooling, and reports any vulnerabilities or malicious packages discovered to repository maintainers and the wider community.
If you've ever used Linux, you’ve probably heard about SELinux or Security-enhanced Linux. For a very long time, my interaction with it was just restricted to: Like many other security solutions, SELinux can sometimes be annoying, and understanding even the basic concepts can change our bigger enemy to our best friend.
In 2001, NIST (the US National Institute of Standards and Technology) announced Advanced Encryption Standard (AES), a new encryption standard, designed to help organisations enhance protections against brute force attacks. The previous Data Encryption Standard (DES) had become vulnerable, with processing power growing, and the Electronic Frontier Foundation (EFF) had proved that DES encryption could be broken in less than 24 hours, therefore a new encryption standard was required.
In 2023, WatchGuard predicts that hackers will try to bypass your cybersecurity defenses using new techniques focused on business processes, identity, and artificial intelligence. This year, Corey and Marc square-off in a Predictions Challenge, offering different takes on potential hacks and attacks in these categories. Whose predictions will come true…only time will tell!
Kroll has observed threat actors abusing Google Ads to deploy malware masquerading as legitimate downloads or software that has been “cracked” or modified to remove or disable features such as copy protection or adware. As part of our analysis of this trend and threat, we have identified specifically that VIDAR malware, an information-stealing trojan, is using Google Ads to advertise spoofed domains and redirect users to fraudulent sites or malware downloads.
If you're an architect, builder, or engineer, you know that one of the most time-consuming parts of starting a new project is setting up the permissions for each subfolder. You must set the permissions for the same folders over and over again for every new project, which can really start to eat into your billable hours. Fortunately, there's a way to save yourself some time by using project templates.
