This rule detects cryptocurrency mining activity within Amazon EC2, AWS Lambda, or Amazon EKS Runtimes, as reported by AWS GuardDuty. It specifically looks for GuardDuty findings related to 'CryptoCurrency', 'CryptoMinerExecuted', or 'BitcoinDomainRequest' and filters out sample findings.
This rule detects when Amazon GuardDuty identifies an Amazon EC2 instance or a container querying algorithmically generated domains (DGA). DGA activity is often indicative of malware attempting to establish command and control (C2) communication with its operators. The rule specifically looks for GuardDuty findings with the product event type 'DGADomainRequest' and filters out sample findings.
This rule detects when Amazon GuardDuty identifies a malicious or suspicious file being executed on an Amazon EC2 instance or a container workload. It specifically looks for GuardDuty findings with product event types 'MaliciousFile' or 'SuspiciousFile', excluding any sample findings.
Detects the execution of the Qakbot uninstaller file, identified by its filename or specific file hashes, as mentioned in the USAO-CDCA document regarding the disruption of the Qakbot malware and botnet. This rule helps identify systems where the Qakbot uninstaller has been run, which could indicate remediation efforts or system compromise.
This rule detects the Helldown ransomware by identifying specific byte patterns associated with its core functionalities. These functionalities include finding files for encryption, the encryption process itself, dropping a ransom note, and attempting to kill virtual machines. The rule specifically targets ELF executables, indicating it's designed for Linux systems.
This rule detects the PygmyGoat backdoor on Linux systems by identifying specific byte patterns associated with its functionality. The patterns include code for creating backdoor sockets, forwarding data, the main constructor, and hooking the accept function, indicating the presence and activity of the PygmyGoat malware.
Amazon GuardDuty detects a malicious or suspicious file on an Amazon EC2 instance or a container workload.
Amazon GuardDuty detects CryptoCurrency activity in Amazon EC2, AWS Lambda or Amazon EKS Runtimes.

Yara rule that detects Helldown ransomware.
This rule detects highly relevant antivirus events in the Windows Application log by looking for specific keywords associated with known virus signatures, malware, and offensive security tools. It aims to identify instances where an antivirus product has detected or quarantined malicious software or activity.
Detects executions of WScript.exe or CScript.exe that are running scripts with common extensions (e.g., .js, .vbs) from suspicious temporary or public user directories. This behavior is often associated with dropper scripts used in initial access or malware delivery.
This rule detects the GomorrahStealer infostealer by identifying specific bytecode patterns associated with its capabilities. These capabilities include extracting browser autofill data, browser cookies, taking screenshots, gathering antivirus information, and collecting browser history. The rule looks for the presence of all these distinct bytecode signatures within a file to confirm the presence of GomorrahStealer.
This Yara rule detects the CyberVolk ransomware by identifying specific byte patterns within its 'manage_gui', 'find_files', and 'encrypt_files' functions. The rule looks for two distinct versions of the 'find_files' and 'encrypt_files' functions, indicating variations in the ransomware's implementation. The presence of these patterns suggests the file is a CyberVolk ransomware executable.
This rule detects the creation of processes with specific SHA1 or SHA256 hashes that have been identified as indicators of compromise (IOCs) associated with the GALLIUM cyber espionage group. These hashes correspond to known malicious executables used by the group. The detection is based on a report by Microsoft Threat Intelligence Center from December 2019, which detailed GALLIUM's targeting of global telecommunications.

Detects highly relevant antivirus alerts indicating the presence of hack tools or other attack tools. This rule emphasizes that even if the antivirus blocks the malware, the event requires investigation to understand how the tool initially compromised the system.
This rule detects highly relevant antivirus alerts that specifically report the presence of a web shell. It is designed to flag antivirus detections where the signature indicates a web shell, often identified by keywords related to common web scripting languages (ASP, PHP, JSP, Perl) and terms like 'Backdoor', 'Webshell', or specific web shell names (C99shell, Chopper). The rule emphasizes that such alerts, even if the malware is blocked, warrant further investigation into how the web shell was initially placed on the system.
Detects a highly relevant Antivirus alert that reports a password dumper. This event must not be ignored just because the AV has blocked the malware but investigate, how it came there in the first place.
Detects an Antivirus alert in a highly relevant file path or with a relevant file name. This event must not be ignored just because the AV has blocked the malware but investigate, how it came there in the first place.
