Infosec Skills Challenge: April 2022


  • MITRE ATT&CK – Resource Development – Webshells Lab — 00:30:00
    • In this lab, the student learns to develop and stage several webshells and how to determine which webshell should be uploaded to a web server. The compromised infrastructure is then used to deploy drive-by attacks.

  • MITRE ATT&CK – Reconnaissance – Mapping DNS Information Lab — 00:30:00
    • This lab entails a series of Mitre ATT&CK techniques and sub techniques with the aim of showcasing the possibility of intertwinement between them. The conjoining of the techniques is done in order to gather information on the victim’s networks and search freely on available technical databases for information which can be used during targeting.

      In order to enumerate DNS a general understanding of DNS and how it functions is required.

      Communication through the internet or private networks requires the identification and localizations of each host and their respective IP address. Nonetheless, remembering IP addresses for each host would be a lengthy and tedious task. Thus, each host is assigned a name known as the domain name. Additionally, the domain name is mapped with the corresponding IP address. The association between the domain name and the IP address is all defined by the Domain Name System (DNS) database. As such, DNS is essentially an internet phone book, which resolves the issue of human read web addresses to IP addresses.

  • MITRE ATT&CK – Resource Development – Malicious Linux Packages Lab — 00:30:00
    • Debian is a robust and reliable system that uses APT as its default package manager. The APT package manager handles how software packages are downloaded and installed on Linux systems, including Debian and Ubuntu. Unofficial package repositories replace any package they want freely, and there is no clear trust path between the user and the developer. The adversaries usually exploit Debian-based systems by creating malicious repositories for the APT packet manager and distributing them to the victims. Once exploited, the vector of attacks proprietary increases.
