JPL's Massive PDF Archive Boosts Malware Research.
NASA's Jet Propulsion Laboratory has created the largest publicly available open-source archive of PDFs, totaling about 8 terabytes, to aid in malware research and improve PDF technology. The archive was created as part of a Defense Advanced Research Projects Agency (DARPA) program called Safe Documents (SafeDocs) and will be used to anticipate emerging online threats. The corpus will also be useful for privacy researchers and software developers. The archive is hosted by Amazon Web Services' Open Data Sponsorship Program and is available for download.
