This rule detects various common methods of achieving persistence on Linux and macOS systems. It monitors file system changes to systemd unit files and macOS LaunchAgent plist files, as well as the execution of commands related to managing systemd services and user crontab entries.
This rule monitors for processes, file names, or command lines that contain the string 'telepuz', which is indicative of a specific malware or malicious toolset. It alerts on any occurrence within process image names, process command lines, or file paths.
Detects execution of the GigaWiper destructive backdoor by identifying internal Go function symbols and specific buffer size constants (0xA00000) used during raw disk overwrite operations.

Detects the creation or modification of a file named 'g11.sys'. This filename is often associated with the deployment of malicious or vulnerable drivers used for kernel-mode exploitation, such as Bring Your Own Vulnerable Driver (BYOVD) attacks or rootkit activity.
Detects modifications to Windows Defender exclusion settings by monitoring both PowerShell command lines containing 'Set-MpPreference' with 'ExclusionPath' and direct Registry modifications to the Defender exclusions key. Threat actors commonly use these techniques to bypass security scanning for malicious files or tools placed in the 'C:\ProgramData' directory.
Detects the use of PowerShell to modify file timestamps by using the timestamps of the legitimate notepad.exe as a reference point. This technique is often used to make malicious files blend in with system files by adopting their creation, access, or write times.
This rule detects file creation, renaming, or modification events targeting files associated with cryptocurrency wallets, such as wallet.dat or files containing the string 'keystore'. Accessing these files is a common technique used by malware or malicious actors to steal cryptocurrency credentials and private keys.
Detects crontab modifications referencing hw_probe.pyc, the cron-based persistence mechanism used by the mrmustard stealer.
Detects the mrmustard stealer's compiled-bytecode artifacts (hw_probe.pyc, .lock_*, .ts_*) dropped in the hidden .tf_cache directory used to evade static source-code review.
Detects strings associated with GigaWiper's unallocateDrive routine, which invokes DeviceIoControl with the IOCTL_DISK_CREATE_DISK control code to erase partition table metadata on non-system drives, followed by a success log message.

Detects execution of the GigaWiper destructive backdoor by identifying internal Go function symbols and specific buffer size constants (0xA00000) used during raw disk overwrite operations.
Detects suspicious modifications or deletions of Outlook calendar events using the Microsoft Graph API, potentially indicating the use of calendar infrastructure as a command-and-control (C2) heartbeat or exfiltration channel. The rule monitors for specific pattern-based event updates or deletions following calendar enumeration, which is a technique used to maintain persistent communication or exfiltrate small amounts of data.
Detects the use of PowerShell to modify file timestamps by using the timestamps of the legitimate notepad.exe as a reference point. This technique is often used to make malicious files blend in with system files by adopting their creation, access, or write times.
Detects the creation or modification of a file at a specific Launch Agent path commonly used for macOS persistence. Attackers often place property list (.plist) files in /Library/LaunchAgents/ to achieve persistence across system reboots or user logons.
Detects a process creating files named 'README.TXT' or 'README.txt' across three or more distinct directories. This behavior is a common indicator of ransomware activity, where an adversary drops ransom notes in multiple folders to maximize visibility after encrypting files.
Detects file write operations performed by 'nvidia-sysruntime.exe', a known masquerading binary used by LabubaRAT. This activity signifies the RAT's operator-directed tasking where attacker-controlled data is written to the file system.

Detects the use of the macOS 'codesign' utility to sign binaries using a self-signed or empty identity certificate. This technique is often used by adversaries to bypass Gatekeeper security controls or to make unsigned malicious binaries appear legitimate.
Detects the installation or referencing of the malicious @injectivelabs/sdk-ts package version 1.20.21. This specific version was identified as containing a credential-stealing backdoor disguised within telemetry code.
