Type Name Severity Module Data source / event ATT&CK
Analytics BIOC A Kubernetes namespace was created or deleted A Kubernetes namespace was created or deleted. Informational Cortex Cloud AWS Audit Log, Azure Audit Log, Gcp Audit Log, Kubernetes Audit Logs Defense Evasion
Analytics BIOC A LOLBIN was copied to a different location To evade detection, attackers may copy a LOLBIN executable to a different location. Informational Platform Analytics XDR Agent Defense Evasion
Analytics BIOC A process is masquerading as a common Microsoft product An attacker might leverage common Microsoft software image names to run malicious processes without being caught. Informational Platform Analytics XDR Agent Defense Evasion
Analytics BIOC A suspicious executable with multiple file extensions was created An executable file with multiple extensions was created. This technique is frequently used to disguise malware as user content. Medium Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Execution, Defense Evasion
Analytics BIOC A third-party utility was copied to a different location To evade detection, attackers may copy a third-party utility executable to a different location. Informational Platform Analytics XDR Agent Defense Evasion
BIOC Common Apple process name missing Apple digital signature These common Apple process names should normally be signed with the Apple Inc. digital signature. Naming processes with common names is a common way attackers obfuscate their activities. Informational Platform Analytics Process execution Defense Evasion
BIOC Common Mozilla process name missing Mozilla digital certificate These common Mozilla process names should normally be signed with the Mozilla Corporation digital signature. Naming processes with common names is a common way attackers obfuscate their activities. Informational Platform Analytics Process execution Defense Evasion
Analytics BIOC Common third-party software name masquerading An attacker might leverage common third-party software image names to run malicious processes without being caught. Informational Platform Analytics XDR Agent Defense Evasion
Analytics BIOC Email attachment with multiple extensions The email includes an attachment(s) with two extensions. The first one being an executable extension. This may indicate an attempt at masquerading the true file type through the misuse of multiple extensions in the attachment name. Informational Email Security Microsoft 365 Emails Execution, Defense Evasion
Analytics BIOC Email attachment with Right-to-Left Override Unicode character The email message contains an attachment with a hidden Right-to-Left Override Unicode character. Low Email Security Microsoft 365 Emails Defense Evasion, Execution
Analytics BIOC Email attachment(s) with potentially malicious MIME type The email message contains an attachment(s) with a potentially malicious MIME type. Informational Email Security Microsoft 365 Emails Defense Evasion, Execution
Analytics BIOC Email containing a link with an IP address convention was detected A link with IP address convention was detected within the email body. Informational Email Security Microsoft 365 Emails Defense Evasion, Execution
Analytics BIOC Executable moved to Windows system folder An attacker may be trying to avoid detection by moving an executable to a Windows system folder. Informational Platform Analytics XDR Agent Defense Evasion
Analytics BIOC Execution of masqueraded third-party utility An attacker may be trying to avoid detection of third-party utility execution by renaming it. Informational Platform Analytics XDR Agent Defense Evasion
Analytics BIOC Execution of renamed lolbin An attacker may be trying to avoid detection of lolbin's execution using a renamed lolbin. Informational Platform Analytics XDR Agent Defense Evasion
BIOC File renamed to have a script extension Adversaries may create 'benign-looking' files, which are later used as malicious scripts by changing their extension. Informational Platform Analytics File Defense Evasion
Analytics BIOC Masquerading as a default local account A user created a new local account with the name of a default local account, such as Guest and DefaultAccount. An attacker may create a user with these known names to evade detection. Low Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Defense Evasion, Persistence
Analytics BIOC Masquerading as the Linux crond process Copies a file and renames it as crond. Low Platform Analytics XDR Agent Defense Evasion
Analytics BIOC Punycode characters detected in URL(s) Punycode character(s) detected within URL(s) in email content. Informational Email Security Microsoft 365 Emails Defense Evasion, Execution
Analytics BIOC Rare service DLL was added to the registry A service was added as a dll, which will be executed by svchost.exe. This is a stealthy technique attackers use to persist their malware. Low Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Defense Evasion, Persistence
BIOC Shell binary copied to another location Attackers may try to evade detection by copying the shell binary to an innocent-looking name. Informational Platform Analytics Process execution Defense Evasion
Analytics BIOC Space after filename A file was created or renamed to have a space at the end of its name. Informational Platform Analytics XDR Agent with eXtended Threat Hunting (XTH) Defense Evasion
BIOC Space after filename creation An attacker may append a space to the end of a filename to change how it's processed by the operating system. Informational Platform Analytics File 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 process accessed a site masquerading as Google A suspicious process accessed a site masquerading as Google. Informational Platform Analytics XDR Agent Command and Control, Defense Evasion
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
Analytics BIOC Suspicious Unicode character detected in email Unicode characters can be used for obfuscation, allowing malicious actors to disguise harmful intent, URLs or attachments By embedding non-printing Unicode characters, attackers can bypass security filters and evade detection mechanisms Such characters may also be used for phishing attempts that appear legitimate to both users and security systems. Informational Email Security Microsoft 365 Emails Defense Evasion
Analytics BIOC Svchost.exe loads a rare unsigned module Svchost.exe loads a rare unsigned module, which can indicate an attacker's malicious service execution. Low Platform Analytics XDR Agent Defense Evasion, Persistence
Analytics BIOC Usage of homograph characters detected in an email Detected characters resembling Latin letters within an email's subject and/or body. This could indicate an attempt to impersonate a well-known brand or impersonate someone's identity. This could also be used as a method to evade text scanners and analyzers. Informational Email Security Microsoft 365 Emails Defense Evasion
Analytics BIOC Usage of homograph characters detected in an email's from header Detected characters resembling Latin letters within an email's From header. This could indicate an attempt to impersonate a well-known brand or impersonate someone's identity. This could also be used as a method to evade text scanners and analyzers. Informational Email Security Microsoft 365 Emails Defense Evasion
BIOC Windows process masquerading by an unsigned process A process is trying to disguise itself as a legitimate Windows process, but is unsigned. This usually indicates malicious activity. Informational Platform Analytics Process execution Defense Evasion
