Detects when an adversary uses the reg.exe utility to add or modify new keys or subkeys
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 Clop ransomware by identifying specific byte patterns related to its file encryption routines, file discovery mechanisms, and its capability to uninstall ESET antivirus software. The rule looks for distinct sequences of bytes that are characteristic of Clop's operational methods.
This YARA rule detects various versions of the GandCrab ransomware family by identifying specific byte patterns associated with its core functionalities. These functionalities include establishing remote connections, encrypting files, searching for files to encrypt, and enumerating antivirus processes to evade detection. The rule uses multiple sets of signatures to cover different versions and obfuscation techniques of GandCrab, ensuring a broad detection capability. The presence of these combined byte patterns within a Windows executable (MZ header check) indicates a high probability of GandCrab ransomware infection.
