Snowden's 'Dead Man's Switch' May Just Make Him A Bigger Target

from the forcing-the-government-to-protect-its-'enemy' dept

Word has it that Ed Snowden has gone all George Smiley and implemented his version of a "dead man's switch," one that will lead directly to a full data dump if anything unpleasant happens to him. What's in these yet-unleaked documents is still a mystery, although Snowden has claimed they provide a "blueprint" of the NSA's surveillance architecture, one that could be probed for weaknesses or replicated.

[S]nowden... reportedly passed encrypted copies of his cache to a number of third parties who have a non-journalistic mission: If Snowden should suffer a mysterious, fatal accident, these parties will find themselves in possession of the decryption key, and they can publish the documents to the world.

"It's not just a matter of, if he dies, things get released, it's more nuanced than that," he said. "It's really just a way to protect himself against extremely rogue behavior on the part of the United States, by which I mean violent actions toward him, designed to end his life, and it's just a way to ensure that nobody feels incentivized to do that."

I'm not sure he's thought this through, though. I would be more worried that someone would kill me in order to get the documents released than I would be that someone would kill me to prevent the documents from being released. Any real-world situation involves multiple adversaries, and it's important to keep all of them in mind when designing a security system.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community. Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis. While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Obviously, Snowden has set this up to prevent the US from deciding to simply take him out, rather than risk any more leaks. This conceivably shifts priorities for the US, which now must take care to ensure Snowden remains unharmed. (It's not explicitly stated whether an arrest or successful extradition to the US will trigger the "switch.") Notably, Snowden doesn't actually have toto set things in motion.Bruce Schneier, however, sees how this "insurance plan" could actually make things more dangerous for Snowden This could make Snowden a target for people whose motivations run from the anti-American (exposed documents will hurt the US) to those who view chaos as its own end (exposed documents will wreak further mayhem in governments worldwide). This sort of action is probably more limited to individual actors rather than agents of unhappy/rival states.If someone did manage to take him out, all eyes would turn to the US government. Whether the government did or didn't do it doesn't matter. It will be assumed it was ordered by the US. And whether or not the US government was behind it, it will issue a denial. This denial, of course, won't be believed because at this point, the government has the credibility of a heroin addict.If the government has taken any of the above into consideration, it's back to having to ensure Snowden remains unharmed and safe, something made even more difficult by Snowden inadvertently painting a target on his own back.
