The problem became especially clear this year during the San Bernardino case, involving the FBI’s demand that Apple rewrite its iOS operating system to defeat security features on a locked iPhone. Ultimately the FBI exploited an existing vulnerability in iOS and accessed the contents of the phone with the help of an "outside party." Then, with no public process or discussion of the tradeoffs involved, the government refused to tell Apple about the flaw. Despite the obvious fact that the security of the computers and networks we all use is both collective and interwoven—other iPhones used by millions of innocent people presumably have the same vulnerability—the government chose to withhold information Apple could have used to improve the security of its phones.
Other examples include intelligence activities like Stuxnet and Bullrun, and law enforcement investigations like the FBI’s mass use of malware against Tor users engaged in criminal behavior. These activities are often disproportionate to stopping legitimate threats, resulting in unpatched software for millions of innocent users, overbroad surveillance, and other collateral effects.
That’s why we’re working on a positive agenda to confront governmental threats to digital security. Put more directly, we’re calling on lawyers, advocates, technologists, and the public to demand a public discussion of whether, when, and how governments can be empowered to break into our computers, phones, and other devices; sabotage and subvert basic security protocols; and stockpile and exploit software flaws and vulnerabilities.
