Security Analysis
What does msdtc.exe normally do?
Runs as a service on systems using distributed transactions (SQL Server, COM+, BizTalk). Coordinates two-phase commit across multiple databases.
When is msdtc.exe suspicious?
DLL loading from non-standard paths. Running on systems that do not use distributed transactions. Spawning unexpected child processes.
How do attackers abuse msdtc.exe?
MSDTC loads DLLs from a configurable path and has been used for DLL side-loading attacks. Attackers can place malicious DLLs in the MSDTC working directory for persistence and execution as SYSTEM.
Detection guidance
Monitor DLLs loaded by msdtc.exe. Alert on non-standard DLL paths. Detect modifications to the MSDTC service configuration.
False positive notes
Normal on SQL Server and application servers using distributed transactions.
