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 HermeticRansom ransomware by identifying specific byte patterns associated with its functionality. The rule looks for patterns related to dropping a ransom note, encrypting files, and finding files to encrypt. The presence of these combined patterns indicates the presence of the HermeticRansom malware.

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 LockBit ransomware by identifying specific byte patterns (signatures) within executable files. It contains two main sets of conditions, likely corresponding to different versions or major functional blocks of the ransomware. The first set looks for patterns related to enumerating resources, finding files, and encrypting files. The second set looks for patterns related to checking blacklisted languages (anti-analysis/anti-geofencing), FNV1a hashing, creating network host traversal threads, decrypting configuration, and encrypting files. The rule requires the file to be a Windows executable (MZ header).

This rule detects the CaddyWiper trojan, a destructive data wiper, by identifying specific byte patterns within executable files. The patterns correspond to functions involved in destroying data if the system is not a controller, erasing drive data, and recursively erasing drives.

This YARA rule detects the IsaacWiper trojan by identifying specific byte patterns related to its functionality. The rule looks for two distinct code sections: one responsible for enumerating physical drives and another for corrupting drive data. The presence of both patterns indicates the likely presence of the IsaacWiper malware, which is known for its destructive disk wiping capabilities.

This YARA rule detects the HermeticWiper malware based on a specific byte sequence ($corrupt_physical_drive) that is characteristic of its functionality to corrupt physical drives. The rule also checks for the standard PE file magic number (MZ header) to ensure it's applied to executable files.

This rule detects the TimeTime ransomware by identifying specific bytecode patterns associated with its file enumeration, encryption, and renaming activities. The rule looks for distinct sequences of operations related to finding files, encrypting files, encrypting folders, and renaming files, which are characteristic behaviors of ransomware.
