Hangul Office (Korean: 한글 오피스) is a proprietary word processing application published by the South Korean company Hancom Inc.. Hangul's specialized support for the Korean written language has gained it widespread use in South Korea, especially by the government.

The software's name is derived from the Korean word Hangul (Korean: 한글, hangeul) for the alphabet used to write Korean.

Document formats[edit]

Hangul saves documents in Hangul office format, with the filename extension *.hwp.[2] It is one of the standard document formats of the South Korean government. It is widely used for a number of reasons: Koreans require DTP level layout features to word processor, and its unique program can process Middle Korean.

HWP files, up to the versions created with Hangul '97, can be opened with OpenOffice.org (version 4.1.1 or earlier[3]) or LibreOffice. However, files created with later editions of Hangul, including Hangul Wordian, Hangul 2002, Hangul 2005 and Hangul 2007 cannot be opened with OpenOffice or LibreOffice, due to the major changes in the document structure. These later versions of Hangul do not provide support for opening and saving of files in Microsoft Word format, but users are not necessarily aware of this. Consequently, Korean Hangul users may often send files to non-Koreans in .hwp format, not realizing the recipient will be unable to open such files.[4]

Hangul was intended in 2009 to gain support for reading and writing of Office Open XML and OpenDocument files.[5]

The HWP binary format specification has been published online free by Hancom on June 29, 2010.[6][7]

Security vulnerabilities[edit]

The Talos team of Cisco has reported vulnerabilities in Hangul, which have been exploited by malware dubbed NavRAT.[8]

Hangul Viewer[edit]

Haansoft offers a freely available Hangul document viewer program called "Hancom Office Viewer 2010 SE" (한컴오피스 뷰어 2010 SE).

Haansoft near bankruptcy[edit]

Haansoft was on the verge of bankruptcy after the release of its 2002 version, due to the widespread use of illegal copies. A campaign to support the development of Korean software and promote the purchase of legal copies of Hangul allowed Haansoft to recover.[9]

The spear phishing messages reference the possible US-North Korean summit and attach a document that exploits a vulnerability in the Hangul Word Processor, which is used in South Korea. Talos said it had medium confidence the emails are the work of a North Korean hacking group they call Group123.
