Description
A malicious stealer app written in C++ and targeting 64-bit Microsoft Windows operating systems. It is designed to substitute crypto wallet addresses that have been copied to the clipboard with ones provided by the attackers.
Operating routine
Trojan.Clipper.231 functions in the context of the %WINDIR%\\System32\\Lsaiso.exe system process where it is injected by the Trojan.Inject4.57873 malware.
The stealer substitutes crypto wallet addresses in the clipboard with addresses assigned by malicious actors. These addresses are hardcoded in the DATA section of the trojan:

Moreover, the trojan verifies if the following processes are present:
L"Taskmgr.exe"
L"procexp.exe"
L"procexp64.exe"
L"procexp64a.exe"
L"Procmon.exe"
L"Procmon64.exe"
L"Procmon64a.exe"
L"ProcessHacker.exe"
L"SystemExplorer.exe"
L"Daphne.exe"
L"myprocesses.exe"
L"TMX.exe"
L"TMX64.exe"
L"DeskExp.exe"
L"DeskExp64.exe"
L"SystemMonitor64.exe"
L"SystemMonitor.exe"
L"WhatsRunning.exe"
L"ExtensionsServer.exe"
L"Ultimate_Process_Killer1.1.exe"
L"DTaskManager.exe"
L"KillProcess.exe"
L"ToolProcessSecurity.exe"
L"spacetornadoKiller.exe"If it detects any of them, it will not substitute crypto wallet addresses.
