Both OJ and Dan have been conducting security assessments for years. Occasionally a discovery is made which warrants discreetly contacting the vendor in question to let them know several thousand (or million) of their devices have a major vulnerability. Sometimes the vendor takes notice and subsequently takes action, however sadly on most occasions they either feign effort, completely ignore the researcher, or openly say ‘go away’. These are a couple stories of how responsible disclosure was attempted, but the company in question couldn’t be troubled to help themselves.
