Download CSV| Type | Name | Severity | Module | Data source / event | ATT&CK |
|---|---|---|---|---|---|
| Analytics BIOC | A process was executed with a command line obfuscated by Unicode character substitution A process was executed with a command line obfuscated by Unicode character substitution. | Medium | Platform Analytics | XDR Agent | Defense Evasion |
| BIOC | Compiler process started by an Office process The processes (csc.exe & vbc.exe) invoke compilers via command prompt and compile a payload on the fly. This is leveraged by attackers to create a new payload on every machine. | Informational | Platform Analytics | Process execution | Defense Evasion |
| Analytics BIOC | Encoded information using Windows certificate management tool Encoding/decoding to/from using certutil.exe could be used to evade detection. | Medium | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Globally uncommon high entropy module was loaded A module with high entropy and a globally uncommon hash was loaded. | Informational | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Globally uncommon high entropy process was executed A process with high entropy and a globally uncommon hash was executed. | Informational | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Possible binary padding using dd A suspicious dd command ran and added data to a binary. This may indicate binary padding to change the hash of a file. | Informational | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Possible malicious .NET compilation started by a commonly abused process Attackers may use csc.exe to compile payloads on a compromised machine. | Medium | Platform Analytics | XDR Agent | Defense Evasion |
| BIOC | Suspicious .NET process spawns csc.exe A suspicious process in the Microsoft .NET directory spawned the C# compiler. This may occur if an attacker masquerades a process like MSBuild (e.g. PowerLessShell). | Low | Platform Analytics | Process execution | Defense Evasion |
| Analytics BIOC | Suspicious data encryption Known applications were used to encrypt data within a machine's local file system. | Low | Platform Analytics | XDR Agent | Impact, 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 | Uncommon AppleScript containing a potential obfuscation technique was executed The AppleScript interpreter process was executed with an obfuscation technique in the command line. | Low | Platform Analytics | XDR Agent | Execution, Defense Evasion |
| Analytics BIOC | Unicode RTL Override Character An attacker may use a special right-to-left (RTL) override character to trick users into executing malicious files that look like benign file types. | High | Platform Analytics | XDR Agent | Defense Evasion |
| Analytics BIOC | Unusual use of a 'SysInternals' tool An attacker may be trying to avoid detection by using an obfuscated copy of SysInternals tools. | Informational | Platform Analytics | XDR Agent with eXtended Threat Hunting (XTH) | Defense Evasion |
