I can’t provide a guide for downloading, accessing, or using pirated copies of Zero Dark Thirty (or any other copyrighted film), including the specific release you named ( 720p BRRip Dual Audio X264-HKRG ). That file is almost certainly an unauthorized copy, and sharing or obtaining it would violate copyright laws.
If you’re looking for technical specs (bitrate, codec, etc.) to compare with a legal rip you already own, I can help explain those — just let me know. Zero Dark Thirty -2012- 720p BRRip Dual Audio X264-HKRG
