| BIOC | Suspicious printer port creation via Registry An attacker may create a print job that prints to a file, overwriting any file on the OS (CVE-2020-1048). | Medium | Platform Analytics | Registry | Privilege Escalation, Persistence |
| Analytics BIOC | Suspicious Process Spawned by wininit.exe An unusual process was spawned by wininit.exe, possibly indicating malicious local or remote code execution. | Medium | Platform Analytics | XDR Agent | Defense Evasion |
| BIOC | Suspicious process spawns MSBuild.exe The Microsoft Build Engine was started by an abnormal process. MSBuild is normally used for development purposes, so this unusual behavior may be malicious. | Medium | Platform Analytics | Process execution | 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 | Suspicious time provider registered The endpoint time provider has been tampered, this change may be used to gain persistence on the host by loading libraries into the time management service. | Medium | Platform Analytics | XDR Agent | Persistence |
| Analytics BIOC | The CA policy EditFlags was queried The CA policy EditFlags was queried. | Medium | Platform Analytics | XDR Agent | Privilege Escalation |
| BIOC | UAC bypass using the changepk.exe Registry key Attackers may use the changepk.exe built-in Windows tool to bypass Windows UAC by modifying Registry keys. | Medium | Platform Analytics | Registry | Privilege Escalation |
| Analytics BIOC | Uncommon AppleScript designed to access credential files was executed via the command line The AppleScript interpreter was executed with a script designed to access credential files such as keychains or SSH keys. | Medium | Platform Analytics | XDR Agent | Execution, Credential Access |
| Analytics BIOC | Uncommon DLL-sideloading from a logical CD-ROM (ISO) device A DLL was loaded by an executable from the same folder on a logical CD-ROM device (ISO). | Medium | Platform Analytics | XDR Agent | Execution, Defense Evasion, Privilege Escalation |
| Analytics BIOC | Uncommon jsp file write by a Java process An uncommon jsp file was written by a Java process. | Medium | Platform Analytics | XDR Agent with eXtended Threat Hunting (XTH) | Persistence |
| Analytics BIOC | Uncommon Service Create/Config The Service Control command (sc.exe) is used to create, start, stop, query, or delete Windows services. Adversaries may attempt to use the command to execute and persist a binary, command, or script. | Medium | Platform Analytics | XDR Agent | Execution |
| Analytics BIOC | Uncommon SetWindowsHookEx API invocation of a possible keylogger A process installed a Windows desktop hook by calling the SetWindowsHookEx API function with an unpopular module. This behavior is commonly seen in keyloggers. | Medium | Platform Analytics | XDR Agent with eXtended Threat Hunting (XTH) | Credential Access, Collection |
| BIOC | Unsigned integer Sudo privilege escalation Fixed in CVE-2019-14287, this known command line is used to exploit a bug in sudo to gain root privileges. | Medium | Platform Analytics | Process execution | Privilege Escalation |
| Analytics BIOC | Unsigned process injecting into a Windows system binary with no command line An attacker may be trying to avoid detection by injecting their malicious code into a legitimate Windows system binary. | Medium | Platform Analytics | XDR Agent | Defense Evasion, Privilege Escalation |
| Analytics BIOC | Unusual process access to ld.so.preload file Attackers can modify ld.so.preload to inject malicious code into every dynamically linked process, enabling persistence and code execution. This detected operation is considered atypical in terms of access. | Medium | Platform Analytics | XDR Agent with eXtended Threat Hunting (XTH) | Persistence |
| BIOC | User added to local administrator group using a PowerShell command Adding a new user to the local admin group may or may not be malicious, but it is an outstanding action worth considering, as it shouldn't happen too often. A malware may add a new malicious user to the administrators group as a way of maintaining high privileges after the system was compromised. | Medium | Platform Analytics | Process execution | Persistence |
| BIOC | Virtual Directory configuration access via PowerShell PowerShell was used to dump Exchange Web Service (EWS) Virtual Directories, which may indicate malicious behavior, for example, SolarStorm campaign. | Medium | Platform Analytics | Process execution | Discovery |
| BIOC | WerFault ReflectDebugger key set in Registry The WerFault.exe signed Windows process may be tricked into running a malicious executable by setting the ReflectDebugger key in the Registry. | Medium | Platform Analytics | Registry | Defense Evasion |
| BIOC | Windows event logs cleared using wmic.exe Attackers may clear events from Windows event logs to remove traces of their malicious activity. | Medium | Platform Analytics | Process execution | Defense Evasion |
| Analytics BIOC | Windows Installer exploitation for local privilege escalation The Windows installer (msiexec.exe) was likely exploited to run a malicious rollback script (.rbs file) instead of the original. Users should not be able to modify config.msi during the installation process, only SYSTEM should have access to it. | Medium | Platform Analytics | XDR Agent | Privilege Escalation |
| Analytics BIOC | Windows LOLBIN executable connected to a rare external host Scripts connecting to external IP addresses may be sanctioned IT scripts. However, when those external IP addresses are only receiving connections from a few specific endpoints in the organization, these scripts may be an indicator of more suspicious activity. Security testers and adversaries use offensive frameworks that employ forms of scripting which result in this type of network activity. | Medium | Platform Analytics | XDR Agent | Command and Control |
