cyberstrikeus T1055.015 ListPlanting
Sub-technique of: T1055
High-Level Description
Adversaries may abuse list-view controls to inject malicious code into hijacked processes in order to evade process-based defenses as well as possibly elevate privileges. ListPlanting is a method of executing arbitrary code in the address space of a separate live process. Code executed via ListPlanting may also evade detection from security products since the execution is masked under a legitimate process.
List-view controls are user interface windows used to display collections of items. Information about an application's list-view settings are stored within the process' memory in a SysListView32 control.
ListPlanting (a form of message-passing "shatter attack") may be performed by copying code into the virtual address space of a process that uses a list-view control then using that code as a custom callback for sorting the listed items. Adversaries must first copy code into the target process’ memory space, which can be performed various ways including by directly obtaining a handle to the SysListView32 child of the victim process window (via Windows API calls such as FindWindow and/or EnumWindows) or other Process Injection methods.
Some variations of ListPlanting may allocate memory in the target process but then use window messages to copy the payload, to avoid the use of the highly monitored WriteProcessMemory function. For example, an adversary can use the PostMessage and/or SendMessage API functions to send LVM_SETITEMPOSITION and LVM_GETITEMPOSITION messages, effectively copying a payload 2 bytes at a time to the allocated memory.
Finally, the payload is triggered by sending the LVM_SORTITEMS message to the SysListView32 child of the process window, with the payload within the newly allocated buffer passed and executed as the ListView_SortItems callback.
Kill Chain Phase
- Defense Evasion (TA0005)
- Privilege Escalation (TA0004)
Platforms: Windows
What to Check
- Identify if ListPlanting technique is applicable to target environment
- Check Windows systems for indicators of ListPlanting
- Verify mitigations are bypassed or absent (1 known mitigations)
- Assess detection coverage (1 detection strategies)
How to Test
Atomic Red Team Tests
The following tests are from Atomic Red Team and provide actionable ways to test this technique:
Atomic Test 1: Process injection ListPlanting
This test injects shellcode into a remote RegEdit process using the ListPlanting technique. ListPlanting exploits Window with ListView control. Code write to memory with NtWriteVirtualMemory. The shellcode is executed via PostMessage. When successful, a message box will appear with the title "Warning" and the content "Atomic Red Team" after a few seconds. Notepad will open following the appearance of the message box.
Supported Platforms: windows Elevation Required: Yes
Start-Process "#{exe_binary}"
Start-Sleep -Seconds 7
Get-Process -Name Notepad -ErrorAction SilentlyContinue | Stop-Process -Force
Dependencies:
- Injector ListPlanting.exe must exist at specified location (#{exe_binary})
Manual Testing
If Atomic Red Team tests are not applicable, manually verify the technique by:
Identify Attack Surface: Determine if the target environment is susceptible to ListPlanting by examining the target platforms (Windows).
Assess Existing Defenses: Review whether mitigations for T1055.015 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
