BitCrypt Ransomware Detection

This YARA rule detects the BitCrypt ransomware based on specific byte patterns found within the executable. The rule looks for a combination of distinct code sequences related to BCDedit manipulation, drive enumeration (A-Z), file extension handling, and core ransomware logic. The detection is anchored to the entry point of a Portable Executable (PE) file, ensuring that the identified patterns are part of the executable's primary code flow.
