In this highly informative DLD25 session, Meredith Whittaker, President of the Signal Foundation, and journalist Kenneth Cukier (The Economist) discuss the crucial role of robust encryption in protecting private communication in today’s digital world.
Whittaker begins her introductory remarks with the alarming case of the Salt Typhoon hack, an operation that exploited weaknesses in U.S. telecommunications infrastructure and allowed criminals to obtain detailed location and account data of millions of targets, including high-profile officials. “They hacked at least Trump or Vance’s phone”, Whittaker notes.
The hackers, presumed to be Chinese, “got that info by using the same back doors that law enforcement mandated the telecommunications infrastructure providers implement”, Whittaker emphasizes.
She also highlights Signal’s unique role as a nonprofit dedicated to privacy-first technology. “In a world where you make profit in tech by monetizing data,” Whittaker says, “you cannot open yourself up to a profit motive” that could compromise privacy. Signal’s reliance on donations, rather than advertising or data monetization, underscores its commitment to this mission, she adds.
The popular messenger app’s encryption protocol is widely recognized as “the gold standard for end-to- end encrypted communications”, Whittaker notes. Even competitors like WhatsApp and Google license the technology, though there are crucial differences in the end products.
Signal’s reputation has led to hundreds of millions of downloads, with users from all walks of life. “It is used by militaries as the core nervous system of their communication”, Whittaker says. “It is used by human rights workers, journalists. Basically name a group you hate, name a group you love”, she continues. “They both use Signal.”
Whittaker warns of government efforts to weaken secure communications through back doors, like the ones exploited by the Salt Typhon hacker group. “Encryption either works for everyone or it works for no one”, she says. “A huge part of my life’s work is to make sure that this infrastructure thrives and survives in an age where I believe that this right is deeply imperiled.”
Watch the video to hear why the stakes of digital privacy are higher than ever; how a loss of secure communication would erode the trust necessary for democratic discourse; and much more.
