This YARA rule detects the Acepy ransomware by identifying specific byte patterns associated with its core functionalities: finding files to encrypt, performing the encryption process, and dropping a ransom note. The rule requires all three patterns to be present within a Windows executable file (indicated by the MZ header) to trigger a detection.

This YARA rule detects the Nokoyawa ransomware by identifying specific byte patterns related to its functionality. The rule looks for patterns associated with enumerating shares, finding files, and encrypting files, which are common behaviors of ransomware. The rule requires all three sets of patterns ($enum_shares, $find_files_p*, and $encrypt_files) to be present, along with the MZ header (uint16(0) == 0x5A4D), indicating an executable file.

This YARA rule detects the NB65 ransomware by identifying specific byte sequences associated with its file encryption, file discovery, and process enumeration functionalities. The rule looks for distinct patterns in the binary that indicate the presence of these malicious behaviors, which are characteristic of ransomware operations.

This YARA rule detects the Monalisa ransomware by identifying specific byte sequences (strings) associated with its core functionalities. These functionalities include finding files for encryption, writing to process memory (potentially for injection or other malicious operations), generating encryption keys, and encrypting files. The rule also checks for the standard Windows PE header (MZ) to ensure it's analyzing an executable.

This YARA rule detects the Koxic ransomware by identifying specific byte patterns related to its core functionalities. These patterns include code for enumerating network shares, finding files on the system, and encrypting files. The rule combines these patterns to increase confidence in detecting Koxic ransomware executables.

This YARA rule detects the Rook ransomware by identifying specific byte patterns associated with its file enumeration, process enumeration, network share enumeration, and file encryption functionalities. The rule looks for distinct sequences of bytes ($find_files, $encrypt_files_p1, $encrypt_files_p2, $encrypt_files_p3, $enum_procs, $enum_shares) that are characteristic of Rook ransomware's operations. The presence of these combined patterns indicates a high probability of Rook ransomware infection.
