Systematic security failures at an elite CIA hacking unit helped lead to the biggest information breach in the agency’s history, according to a partially declassified CIA report provided to Sen. Ron Wyden’s office.

Details: The 2017 report, first reported by the Washington Post, is a postmortem on the 2016 breach, conducted by the CIA’s WikiLeaks task force.

  • WikiLeaks revealed the data leak, known as Vault 7, in early 2017. Vault 7 revealed operations and exploits conducted and developed by the CIA’s Center for Cyber Intelligence, which houses the agency’s elite hackers.

What it says: “CIA has moved too slowly to put in place the safeguards that we knew were necessary given successive breaches to other U.S. Government agencies,” the report states.

  • The lack of “user monitoring” and other audit capabilities meant the CIA was unaware of the breach until WikiLeaks had actually published documents from the stolen tranche.
  • If a traditional nation-state adversary had stolen the information, and kept its possession of it secret, the CIA might still not know that its data had been breached at such a massive scale, says the report.

By the numbers: Between 180 gigabytes and 34 terabytes of information were pilfered, says the report, “roughly equivalent to 11.6 million to 2.2 billion pages in Microsoft Word.”

  • This is a huge range that reveals just how much uncertainty exists within the CIA over the extent of the damage.

The state of play: In 2018, U.S. prosecutors charged Joshua Schulte, a former CIA employee, of being WikiLeaks’ source for the Vault 7 leaks.

  • In March, Schulte’s trial ended in a hung jury, though he was convicted of lesser charges.
  • Prosecutors plan on retrying Schulte on espionage-related charges.

The heads of the U.S. Chamber of Commerce, Business Roundtable, National Retail Federation and other top business organizations wrote an open letter on Thursday urging the White House coronavirus task force to work with governors to make face coverings mandatory in all public spaces.

Driving the news: An analysis led by Goldman Sachs' chief economist found that a national mandate requiring face coverings would "could potentially substitute for lockdowns that would otherwise subtract nearly 5% from GDP," the Washington Post reports.

Scientists are inching closer to understanding how antibodies and immune cells are unleashed by the body in response to the novel coronavirus.

Why it matters: Natural immunity differs from that afforded by vaccination but it offers clues for the design of effective vaccines and therapies.
