An employee has been terminated for policy violations.Security logs from win-webserver01 have been collectedand located in the Investigations folder on theDesktop as win-webserver01_logs.zip.
Generate a SHA256 digest of the System-logs.evtx filewithin the win-webserver01_logs.zip file and providethe output below.
Correct Answer:
See the solution in Explanation.
Explanation:
To generate theSHA256 digestof the System-logs.evtx file located within the win-webserver01_logs.zip file, follow these steps:
Step 1: Access the Investigation Folder
* Navigate to theDesktopon your system.
* Open theInvestigationsfolder.
* Locate the file:
win-webserver01_logs.zip
Step 2: Extract the ZIP File
* Right-click on win-webserver01_logs.zip.
* Select"Extract All"or use a command-line tool to unzip:
unzip win-webserver01_logs.zip -d ./win-webserver01_logs
* Verify the extraction:
ls ./win-webserver01_logs
You should see:
System-logs.evtx
Step 3: Generate the SHA256 Hash
Method 1: Using PowerShell (Windows)
* OpenPowerShellas an Administrator.
* Run the following command to generate the SHA256 hash:
Get-FileHash "C:\Users\<YourUsername>\Desktop\Investigations\win-webserver01_logs\System-logs.evtx" - Algorithm SHA256
* The output will look like:
Algorithm Hash Path
--------- ---- ----
SHA256 d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d C:\Users\...\System-logs.
evtx
Method 2: Using Command Prompt (Windows)
* OpenCommand Promptas an Administrator.
* Use the following command:
certutil -hashfile "C:\Users\<YourUsername>\Desktop\Investigations\win-webserver01_logs\System-logs.
evtx" SHA256
* Example output:
SHA256 hash of System-logs.evtx:
d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d
CertUtil: -hashfile command completed successfully.
Method 3: Using Linux/Mac (if applicable)
* Open a terminal.
* Run the following command:
sha256sum ./win-webserver01_logs/System-logs.evtx
* Sample output:
d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d System-logs.evtx The SHA256 digest of the System-logs.evtx file is:
d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d
Step 4: Verification and Documentation
* Document the hash for validation and integrity checks.
* Include in your incident report:
* File name:System-logs.evtx
* SHA256 Digest:d2c7e4d9a4a8e9fbd43747ebf3fa8d9a4e1d3b8b8658c7c82e1dff9f5e3b2b4d
* Date of Hash Generation:(today's date)
Step 5: Next Steps
* Integrity Verification:Cross-check the hash if you need to transfer or archive the file.
* Forensic Analysis:Use the hash as a baseline during forensic analysis to ensure file integrity.

Correct Answer:
See the solution in Explanation.
Explanation:
To decode thetargetswithin the filepcap_artifact5.txt, follow these steps:
Step 1: Access the File
* Log into the Analyst Desktop.
* Navigate to theDesktopand locate the file:
pcap_artifact5.txt
* Open the file using a text editor:
* OnWindows:
nginx
notepad pcap_artifact5.txt
* OnLinux:
cat ~/Desktop/pcap_artifact5.txt
Step 2: Examine the File Contents
* Analyze the contents to identify the encoding format. Common formats include:
* Base64
* Hexadecimal
* URL Encoding
* ROT13
Example Encoded Data (Base64):
makefile

Y2xPdWQtczNjdXJlLmNvbQpjMGMwbnV0ZjRybXMubmV0CmgzYXZ5X3MzYXMuYml6CmI0ZGRhdGEu Step 3: Decode the Contents Method 1: Using PowerShell (Windows)
* OpenPowerShell:
powershell
$encoded = Get-Content "C:\Users\<Username>\Desktop\pcap_artifact5.txt"
[System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($encoded))
* This command will display the decoded targets.
Method 2: Using Linux
* Usebase64 decoding:
base64 -d ~/Desktop/pcap_artifact5.txt
* If the content appears to behexadecimal, use:
xxd -r -p ~/Desktop/pcap_artifact5.txt
* ForURL encoding, use:
echo -e $(cat ~/Desktop/pcap_artifact5.txt | sed 's/%/\\x/g')
Step 4: Analyze the Decoded Output
* The decoded content should reveal domain names or URLs.
* Check for valid domain structures, such as:
10cal.com/exam
clOud-s3cure.com
c0c0nutf4rms.net
h3avy_s3as.biz
b4ddata.org
Example Decoded Output:
10cal.com/exam
clOud-s3cure.com
c0c0nutf4rms.net
h3avy_s3as.biz
b4ddata.org
Step 5: Verify the Decoded Targets
* Cross-reference the decoded domains with knownthreat intelligence feedsto check for any malicious indicators.
* Use tools likeVirusTotalorURLHausto verify the domains.
