This rule detects the GhosTEncryptor ransomware by identifying specific byte patterns related to its folder enumeration and encryption routines. The rule looks for a combination of patterns that indicate the ransomware's logic for enumerating folders and encrypting files within those folders, as well as deep search functionalities. The presence of these specific byte sequences, along with the MZ header, strongly suggests the presence of GhosTEncryptor.

This rule detects the Namaste ransomware by identifying specific bytecode patterns associated with its file discovery and encryption routines. The rule looks for distinct sequences of MSIL (Microsoft Intermediate Language) instructions that are characteristic of how Namaste ransomware locates files on a system and subsequently encrypts them. The `find_files_p*` strings target patterns related to file system enumeration, while the `encrypt_files_p*` strings target patterns involved in the encryption process itself. The rule also checks for the standard PE file magic number (0x5A4D) to ensure it's analyzing an executable.
