A cybersecurity firm is working with the Vatican to defend its priceless collection of digitized writings from hacking efforts.

Why it matters: Digitizing library archives can provide an invaluable backup should the originals be lost or destroyed, but they're also vulnerable to cyberattacks. Without stout defenses, digital libraries can be looted or even vandalized.

What's happening: The more than 500-year-old Vatican Library, which holds among other historical treasures the oldest surviving copy of the Bible, has been in the process of digitizing over 80,000 of its rarest documents.

  • The digital archive "allows more people to explore the world’s history firsthand," says Manlio Miceli, chief information officer for the Vatican Library.
  • But the archive also presents a tempting target to hackers, which is why the Library announced last month that it would begin working with the cyber AI company Darktrace to defend its digital treasures.

How it works: Justin Fier, the director for cyber intelligence and analysis at Darktrace, says the company has been defending the library against about 100 hacking attempts per month.

  • As part of its cyberdefense efforts, Darktrace is employing what it calls an "enterprise immune system," which develops an ongoing understanding of normal activity within the Vatican Library's digital operations, so it can quickly detect when something is off.
  • "What we can do is tell you what's usual and what's unusual," says Fier. "And 90% of the time, the unusual turns out to be either intentionally or unintentionally malicious."

The bottom line: As a former Catholic altar server, I just want to know whether hacking the Pope counts as a venial or a mortal sin.

Stalemate over filibuster freezes Congress

Senate Majority Leader Chuck Schumer and Mitch McConnell's inability to quickly strike a deal on a power-sharing agreement in the new 50-50 Congress is slowing down everything from the confirmation of President Biden's nominees to Donald Trump's impeachment trial.

Why it matters: Whatever final stance Schumer takes on the stalemate, which largely comes down to Democrats wanting to use the legislative filibuster as leverage over Republicans, will be a signal of the level of hardball we should expect Democrats to play with Republicans in the new Senate.

President Biden will seek a five-year extension of the New START nuclear arms control pact with Russia before it expires on Feb. 5, senior officials told the Washington Post.

Why it matters: The 2010 treaty is the last remaining constraint on the arsenals of the world's two nuclear superpowers, limiting the number of deployed nuclear warheads and the bombers, missiles and submarines which can deliver them.

Facebook refers Trump ban to independent Oversight Board for review

Facebook's independent Oversight Board has accepted a referral from the platform to review its decision to indefinitely suspend former President Trump.

Why it matters: While Trump critics largely praised the company's decision to remove the then-president's account for potential incitement of violence, many world leaders and free speech advocates pushed back on the decision, arguing it sets a dangerous precedent for free speech moving forward.
