In this blog post, we will be solving the Magnet Virtual Summit Windows 11 CTF created by Magnet Forensics. Below is the solution to the challenge, solved using ArtiFast Suite.
We are searching for an unconventional email service that the user utilized, excluding mainstream providers like Gmail, Hotmail, and Yahoo. To investigate, we examined the user's web activity using ArtiFast's "Web Activity" category. By analyzing the "Chrome Logins" artifact, we discovered that the user employed the proton.me (ProtonMail) service for their emails. MichaelKBorchardt@proton.me is the answer
In order to identify a program that was installed on the system, we examined the registry artifacts since typically installed programs are stored there. Using ArtiFast, we explored the "Registry" category and specifically investigated the "Installed Programs" artifact. Our analysis revealed that the user had installed BlueStacks5 and BlueStacks X.
To address this question, we relied on the "Windows Event Logs" artifact within the "OS" category. By utilizing our filter, we searched for the results specifically within the "Microsoft-Windows-Ntfs%4Operational.evtx" log. Within this log, we examined the "LITEON CA1-8D256-HP" entry, which provided us with the model number "LITEON CA1-8D256-HP."
To address this question, we utilized ArtiFast's built-in filesystem viewer to navigate through the filesystem. During this exploration, we discovered a text file named "Employee Logins.txt" located on the desktop of the user named "borch." By using ArtiFast's built-in file viewer, we examined the contents of this file and found the password to be ",a]JEU0yG^+]2O]". It is worth noting that the user has a pattern of saving their credentials in pairs, separated as seen in the first two lines of the file. We selected this password specifically because it corresponds to a Google virtual machine (VM).
Returning to the "Installed Programs" artifact within ArtiFast's "Registry" category, we discovered that the sole unarchiving program installed on the system is 7-Zip V22.01. Further research conducted on the internet confirms that 7-Zip introduced VHDX support in version 21.07.
By examining ArtiFast's "Remote Desktop Connection Events Log" artifact within the "Registry" category, we were able to identify RDP connection events performed by the user, along with their event details. Among these events, the most frequently accessed destination IP address was 22.214.171.124. By conducting a geolocation lookup on this IP address using one of the IP geolocation websites, we determined that it corresponds to Columbus, Ohio.
In order to address this question, we utilized ArtiFast's search feature to look for the keyword "Mastodon" and examined the results. By analyzing the "Chrome Visits" artifact within the "Web Activity" category, we discovered that the user frequently visited a profile named "email@example.com". By visiting the associated website URL, we were able to determine that the name of the user is Armin Briegel.
To find the GitHub repository that was accessed using PowerShell, we examined the PowerShell history using ArtiFast's "PowerShell" artifact within the "OS" category. From the artifact, we observed that a git command was executed for the repository at https://github.com/LSPosed/MagiskOnWSALocal. By visiting this GitHub repository, we discovered that the prominent sponsor associated with it is "yujincheng08".
To locate a specific YouTube video, we utilized ArtiFast's search feature to simplify our task. Among the search results, we found a few YouTube links within the "Chrome History" artifact. After visiting each of the links, we discovered that one of them was a video by BenBonk titled "20 Game Developers Made This Game." Therefore, the answer to the question is 20.
To search for search history, we relied on the "Chrome History" artifact. Considering the mention of a "bell" and the context of a fast food item, we focused on Taco Bell as a potential fast food chain. Utilizing ArtiFast's keyword search feature, we discovered that the user had opened a YouTube video titled "Ranking The 'Healthiest' Taco Bell Items." According to this video, the unhealthiest food item among the options discussed is the "breakfast crunchwrap sausage supreme."
To address this question, we examined the user's address by exploring the autofill data in the Chrome browser using ArtiFast's "Chrome Autofill" artifact. From this artifact, we discovered an address saved in the Chrome autofill as "302 Priestford Rd." By searching for this address on a map, we found that it is located on the same street as a body of water called "Deer Creek."
Upon revisiting the "Installed Programs" artifact within ArtiFast, we identified a program named "WSA PaCMan." This program serves as a management tool for Android devices on Windows. Notably, the default port used by WSA PaCMan is 58526.
To address this question, we utilized ArtiFast's search feature to search for the term "clang." The search results revealed the presence of an Android Studio plugin called "Clang." In further investigation related to PCA (Program Compatibility Assistant), we discovered a file named "%systempartition%\Windows\appcompat\pca\PcaGeneralDb0.txt." Within this file, we found that the exit code for "Clang" is listed as "0xc0000135”.
