The security advocacy group Global Cyber Alliance tested the 26 email domains managed by the Executive Office of the President (EOP) and found that only one fully implements a security protocol that verifies the emails as genuinely from the White House. Of the 26 domains, 18 are not in compliance with a Department of Homeland Security directive to implement that protocol.

Why it matters: Imagine the havoc someone could cause sending misinformation from a presidential aide's account: Such fraudulent messages could be used in phishing campaigns, to spread misinformation to careless reporters, or to embarrass White House employees by sending fake tirades under their names.

The details: Email was not originally designed with security in mind. Any person can send any message with any email address listed as the sender. The security protocol DMARC allows an email provider to request that another server verify that an email was sent from the claimed sender.

  • DMARC allows a would-be-faked email server to tell the recipient of a scam to delete a fraudulent email, send it to spam or do nothing at all.
  • The Department of Homeland Security issued a binding directive in October that federal agencies had to start using DMARC within 90 days. Eighteen of the 26 EOP domains have not done this yet, per Global Cyber Alliance's work.
  • Seven of the remaining domains are using DMARC, but do not have it set to alert email providers to move fake emails from inboxes to spam or trash. Only one of the domains has it set to remove the emails from the inbox and head off a potential scam.

A Chinese lander carrying a rover successfully touched down on Mars for the first time, state media reports.

Why it matters: This is the first time China has landed a spacecraft on another planet, and it launches the nation into an elite club of only a few space agencies to successfully make it to the Martian surface.

The United Nations warned Friday that ongoing fighting between Israel and Hamas "has the potential to unleash an uncontainable security and humanitarian crisis," in not only the occupied Palestinian territories and Israel, but "the region as a whole."

The big picture: More than 125 Palestinians, including 31 children have been killed in Gaza since fighting began Monday, per the Palestinian Ministry of Health. Eight people, including two children, have been killed in Israel, Reuters reported, citing Israeli authorities.
