Kategorie: Worm
Würmer verbreiten sich in Computernetzwerken über Netzwerkressourcen. Im Gegensatz zu Net-Worms muss ein Benutzer einen Wurm starten, damit er aktiviert wird.Diese Art von Wurm durchsucht entfernte Computernetzwerke und kopiert sich in Verzeichnisse, auf die Lese- / Schreibzugriff besteht (falls sie welche findet). Darüber hinaus verwenden diese Würmer entweder eingebaute Betriebssystemfunktionen, um nach zugänglichen Netzwerkverzeichnissen zu suchen und / oder sie suchen zufällig nach Computern im Internet, stellen eine Verbindung zu ihnen her und versuchen, vollen Zugriff auf die Festplatten dieser Computer zu erhalten.
Diese Kategorie umfasst auch jene Würmer, die aus dem einen oder anderen Grund nicht in eine der anderen oben definierten Kategorien passen (zB Würmer für mobile Geräte).

Discovery
The adversary is trying to figure out your environment.
Discovery consists of techniques an adversary may use to gain knowledge about the system and internal network. These techniques help adversaries observe the environment and orient themselves before deciding how to act. They also allow adversaries to explore what they can control and what’s around their entry point in order to discover how it could benefit their current objective. Native operating system tools are often used toward this post-compromise information-gathering objective.

System Information Discovery
An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture. Adversaries may use the information from System Information Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
Tools such as Systeminfo can be used to gather detailed system information. If running with privileged access, a breakdown of system data can be gathered through the
Infrastructure as a Service (IaaS) cloud providers such as AWS, GCP, and Azure allow access to instance and virtual machine information via APIs. Successful authenticated API calls can return data such as the operating system platform and status of a particular instance or the model view of a virtual machine.(Citation: Amazon Describe Instance)(Citation: Google Instances Resource)(Citation: Microsoft Virutal Machine API)
Tools such as Systeminfo can be used to gather detailed system information. If running with privileged access, a breakdown of system data can be gathered through the
systemsetup configuration tool on macOS. As an example, adversaries with user-level access can execute the df -aH command to obtain currently mounted disks and associated freely available space. Adversaries may also leverage a Network Device CLI on network devices to gather detailed system information (e.g. show version).(Citation: US-CERT-TA18-106A) System Information Discovery combined with information gathered from other forms of discovery and reconnaissance can drive payload development and concealment.(Citation: OSX.FairyTale)(Citation: 20 macOS Common Tools and Techniques)Infrastructure as a Service (IaaS) cloud providers such as AWS, GCP, and Azure allow access to instance and virtual machine information via APIs.
