Download CSV| Type | Name | Severity | Module | Data source / event | ATT&CK |
|---|---|---|---|---|---|
| Analytics BIOC | A compiled HTML help file wrote a script file to the disk A compiled HTML help file wrote a script file to the disk. Compiled HTLM help files usually don't write script files to the disk. This behavior is often employed by malware that leverages malicious CHM files to deliver a 2nd stage payload. | Low | Platform Analytics | XDR Agent with eXtended Threat Hunting (XTH) | Defense Evasion |
| Analytics BIOC | Conhost.exe spawned a suspicious cmd process Attackers may abuse the conhost process to execute malicious files and evade detection. | Low | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Execution of dllhost.exe with an empty command line The process dllhost.exe was executed with an empty command line. This behavior is suspicious, and may be caused by a malicious actor using 'Image File Execution Options' in the registry to evade detection. | Low | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Globally uncommon image load from a signed process A signed process loaded a DLL that, on a global level, it usually doesn't load. | Informational | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Globally uncommon injection from a signed process A signed process injected into another process that it does not normally target at a global level. | Informational | Platform Analytics | XDR Agent | Defense Evasion, Persistence |
| Analytics BIOC | Globally uncommon IP address connection from a signed process A signed process connected to an external IP address that, on a global level, it usually doesn't connect to. | Informational | Platform Analytics | XDR Agent | Defense Evasion, Command and Control |
| Analytics BIOC | Globally uncommon root domain from a signed process A signed process connected to an external domain that, on a global level, it usually doesn't connect to. | Low | Platform Analytics | XDR Agent | Defense Evasion, Command and Control |
| Analytics BIOC | Globally uncommon root-domain port combination from a signed process A signed process connected to an external domain on a specific port that, on a global level, it usually doesn't connect to. | Low | Platform Analytics | XDR Agent | Defense Evasion, Command and Control |
| Analytics BIOC | Mshta.exe launched with suspicious arguments Microsoft HTML application host process has been launched with suspicious arguments, which may indicate malicious intent. | Low | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Mshta.exe spawns from a browser process Mshta is the Microsoft HTML Application Host. It executes HTML applications on Windows. Detected when a browser process has spawned mshta, which can be a potential attack vector. | Low | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | MSI accessed a web page running a server-side script The Microsoft installer command line included a URL to a web page running a server-side script, which is suspicious. | Informational | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Msiexec execution of an executable from an uncommon remote location Msiexec is the command-line utility for the Windows Installer. Adversaries may abuse msiexec.exe to proxy execution of malicious payloads from remote locations. | Informational | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Possible code downloading from a remote host by Regsvr32 Regsvr32 may be used to fetch arbitrary code from a remote host and execute it without dropping the payload onto the disk. Known to be used for malicious purposes. | Medium | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Registration of Uncommon .NET Services and/or Assemblies Regasm.exe and regsvcs.exe are used to register .NET COM assemblies, which are typically located in specific paths, attackers might leverage that to execute code within a Microsoft signed binary. | Informational | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Rundll32.exe executes a rare unsigned module Rundll32.exe executes a rare unsigned module, which can indicate an attacker's malicious execution. | Low | Platform Analytics | XDR Agent | 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 |
| Analytics BIOC | Suspicious certutil command line An attacker may use certutil to download malware. | Medium | Platform Analytics | XDR Agent | Command and Control, Defense Evasion |
| Analytics BIOC | Suspicious SearchProtocolHost.exe parent process SearchProtocolHost.exe has been launched from a process that is different from SearchIndexer.exe This may indicate malicious activity (such as malware later being injected to it, or it being used for phantom DLL hijacking). | Medium | Platform Analytics | XDR Agent | Execution, Defense Evasion |
| Analytics BIOC | Uncommon execution of ODBCConf Attackers may abuse the Odbcconf.exe Windows utility to proxy the execution of malicious DLL files. | Low | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Uncommon msiexec execution of an arbitrary file from a remote location Msiexec is the command-line utility for the Windows Installer. Adversaries may abuse msiexec.exe to proxy execution of malicious payloads from remote locations. | Low | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Unusual Lolbins Process Spawned by InstallUtil.exe An unusual process was spawned by InstallUtil.exe, possibly indicating malicious local or remote code execution. | Low | Platform Analytics | XDR Agent | Defense Evasion |
