| Analytics BIOC | Procdump executed from an atypical directory Procdump.exe is a SysInternals tool used to dump process memory; it can be used to dump lsass.exe memory to extract credentials. | Medium | Platform Analytics | XDR Agent | Defense Evasion, Credential Access |
| BIOC | Process attempts to kill a known security/AV tool This process has attempted to use taskkill.exe to terminate a known AV process or security analysis tool. Likely attempt to evade detection. | Medium | Platform Analytics | Process execution | Defense Evasion |
| BIOC | Rundll32.exe launches an executable using ordinal numbers argument Rundll32.exe launches an executable using ordinal numbers argument, this behavior may be used by attackers to evade detection. | Medium | Platform Analytics | Process execution | Defense Evasion |
| Analytics BIOC | Rundll32.exe running with no command-line arguments Rundll32.exe is meant to run with parameters, so the absence of them is extremely suspicious; this behavior is used in the default configuration of Cobalt Strike. | Medium | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Rundll32.exe spawns conhost.exe This unusual parent-child process relationship may indicate that an attacker has abused rundll32.exe to run a console-based application such as PowerShell. | Medium | Platform Analytics | XDR Agent | Defense Evasion |
| BIOC | Rundll32.exe was used to run JavaScript Attackers may execute malicious JavaScript code (either remotely or locally) using rundll32.exe. | Medium | Platform Analytics | Process execution | Defense Evasion |
| BIOC | Rundll32.exe with 'main' as EntryPoint Rundll32.exe ran with 'main' as EntryPoint. Attackers may leverage rundll32.exe to execute malicious functions and DLLs. | Medium | Platform Analytics | Process execution | Defense Evasion |
| Analytics BIOC | Suspicious .NET process loads an MSBuild DLL A suspicious process in the Microsoft .NET directory loaded the Microsoft Build Framework DLL.
