In a terrifying trend being witnessed quite often, Volkswagon effectively used the courts to gag security researchers from disclosing security flaws in their keyless ignition system for two years (emphasis added):

They took their findings about the weaknesses in the cryptography and authentication protocol to the Swiss manufacturer of the chip in February 2012, giving them nine months to fix the flaw; then they took their research to Volkswagen in May 2013. They had planned to present their research at USENIX 2013, but Volkswagen argued its vehicles would be at risk of theft and filed a lawsuit to block the paper from being published.

Although the code had been available on the Internet since 2009, the UK High Court of Justice awarded an injunction that prohibited the authors, their institutions, and anyone else who might assist them from publishing the research. The British court wrote, “I recognize the high value of academic free speech, but there is another high value, the security of millions of Volkswagen cars.”

So much for doing the right thing by responsibly disclosing the security flaw.

Indeed, so much for doing the right thing. Good guys never win.
