Yara rule that detects MountLocker ransomware.
This YARA rule detects the Knot ransomware by identifying specific byte patterns related to its file encryption routines, file discovery mechanisms, and remote connection capabilities. The rule looks for distinct sequences of bytes that are characteristic of how Knot ransomware encrypts files, finds target files on a system, and establishes remote connections, indicating the presence and activity of this specific malware.

Yara rule that detects Zeoticus ransomware.
This YARA rule detects the Vovalex ransomware by identifying specific byte patterns associated with its file encryption and file discovery routines. The rule looks for a combination of patterns related to how the ransomware encrypts files and how it finds files on the system, ensuring a high confidence detection of the Vovalex malware.
Yara rule that detects DearCry ransomware.
Yara rule that detects Vovalex ransomware.
This YARA rule detects the AnteFrigus ransomware by identifying specific byte patterns associated with its core functionalities. These functionalities include finding files on the system, encrypting files, and establishing remote connections, likely for command and control or data exfiltration. The rule also checks for the standard Windows executable 'MZ' header.
This rule detects the HentaiOniichan ransomware based on specific byte patterns found in its executable code. The patterns indicate functionalities related to finding files, injecting code into processes, encrypting files, and establishing remote connections. The rule specifically looks for the MZ header (0x5A4D) to confirm it's a Windows executable and then matches against all defined string patterns for high confidence detection.

Yara rule that detects Hentai Oniichan ransomware.
This YARA rule detects the FuxSocy ransomware by identifying specific byte patterns associated with its file encryption and file discovery functionalities. The rule targets Windows executable files (indicated by the 'MZ' header) and looks for distinct code sequences that perform actions typical of ransomware, such as locating files on the system and subsequently encrypting them.

This Yara rule detects the Plague17 ransomware by identifying specific byte sequences associated with its file finding, file encryption, and remote connection functionalities. The rule looks for distinct patterns in the malware's code related to these core ransomware behaviors.

Yara rule that detects InfoDot ransomware.
This rule detects the ShadowCryptor ransomware based on specific byte patterns indicative of its file finding, file encryption, and antivirus termination routines. The rule looks for a combination of these patterns within a PE file to identify the ransomware.
This YARA rule detects the WinWord64 ransomware by identifying specific byte patterns related to remote connections, file encryption routines, and file discovery mechanisms. The rule looks for a combination of these patterns within a PE file (indicated by 'uint16(0) == 0x5A4D' for 'MZ' header). The 'remote_connection_p*' strings suggest network communication capabilities, while 'encrypt_files_p*' strings indicate file encryption functionality, and 'find_files' points to file enumeration or discovery.

Yara rule that detects WinWord64 ransomware.
This YARA rule detects the 'Major' ransomware by identifying specific byte patterns related to file enumeration, file encryption routines, and remote connection capabilities. The rule looks for a combination of these patterns within a Windows executable (MZ header).
