Live notes from HOPE XI
Garrett Robinson, CTO of Freedom of Press Foundation and Lead Developer of Secure Drop
Secure Drop debuted at HOPE X in 2014. FPF was founded in 2012, initially to crowd fund for WikiLeaks. They’ve been doing more crowdfunding for various open-source encryption tools for journalists, and for whistleblower Chelsea Manning’s legal defense. They’re also suing the federal government to respond to FOIA requests. But their main project is SecureDrop.
Over the past couple years, a lot of the plans for SecureDrop happened, and a lot changed. Last year, SecureDrop was installed at 12 independent organizations. They are a mixture of big and small media outlets, and activist nonprofits. All but one still uses the software, and several more have installed it, with a current total of 26 active installations. They’ve improved documentation to make installation easier. There’s a high demand. More organizations are waiting for help in installation and training.
FTF intentionally discourages media outlets from acknowledging which information was received via SecureDrop, which makes outreach complicated. SecureDrop was acknowledged as being used by hackers who exposed violations of attorney-client privilege by prison phone provider Securus.
As an internet service open to the public, SecureDrop attracts trolls. At The New Yorker, over half of their submissions were fiction or poetry.
The current project goals are: 1. keep SecureDrop safe, 2. Make SecureDrop easier for journalists to use, and 3. make SecureDrop easier to deploy and maintain.
Keeping SecureDrop safe. Tor hidden services enable end-to-end encryption with perfect forward secrecy without using certificate authorities. The NSA has had difficulty e-anonymizing Tor (as of 2012). Since then, the FBI has been able to install malware on users’ computers allowing the de-anonymization of Tor hidden services. In 2014, Tor identified a possible attack, which turned out to be a large-scale operation coordinated by multiple states, called Operation Onymous. This attack was made possible by researchers at CMU working with the FBI. Tor was able to blacklist the attackers and block them out eventually. Directories of hidden services have been shown to enable correlation attacks. A 2015 USENIX paper by Kwon et al. has shown that it’s possible to use machine learning and a single malicious Tor node to de-anonymize SecureDrop users, without leaving a trace.
Making SecureDrop easier to use. Doing experiments with using software isolation like Qubes to make air-gaps unnecessary. If the system isn’t usable, journalists either don’t use it or work around the security in harmful ways.
Making SecureDrop easier to deploy. There is a support process in place, but it’s inefficient. The documentation, when printed out, is 138 places. As an aside, Garrett wants a Guy Fawkes toaster.
Garrett wants to live in a world where SecureDrop is obsolete. He wants to live in a world where standard technology enables privacy at the level of SecureDrop. There’s been some progress. Open Whisper Systems has developed Signal and enabled end-to-end encryption for WhatsApp (even though there are security concerns with metadata collection).
