According to White House Homeland Security Advisor Tom Bossert, there are "technical links to previously identified North Korean cyber tools" that helped the U.S. trace the origin of the WannaCry ransomware attack, which stemmed from the NSA cyber arsenal. However, Bossert told reporters Tuesday morning that much of the information that led the U.S. to declare North Korean responsibility is private.

Context: WannaCry is thought to have been launched via an advanced persistent threat group called Lazarus Group, which is suspected of having links with North Korea. That group was suspected of launching an attack on Sony before the release of "The Interview," which showed Kim Jong-un being assassinated. The group also allegedly tried to pull off a bank heist via the central bank of Bangladesh.

What else we know:

  • Bossert said he doesn't believe that North Korea got a lot of the money it raised from the WannaCry attack.
  • The Department of Homeland Security is now calling on all companies to commit to U.S. collective defense, per Jeanette Manfra, assistant secretary for the Office of Cybersecurity and Communications at DHS. But Bossert wouldn't go so far as to say that an attack on a U.S. company constitutes an attack on the country.
  • DHS plans to move beyond offering voluntary assistance on cybersecurity issues and instead plans on intervening directly when necessary, per Manfra.

Trump tightens screws on ByteDance to sell Tiktok

President Trump added more pressure Friday night on China-based TikTok parent ByteDance to exit the U.S., ordering it to divest all assets related to the U.S. operation of TikTok within 90 days.

Between the lines: The order means ByteDance must be wholly disentangled from TikTok in the U.S. by November. Trump had previously ordered TikTok banned if ByteDance hadn't struck a deal within 45 days. The new order likely means ByteDance has just another 45 days after that to fully close the deal, one White House source told Axios.

In her first sit-down interview since being named Joe Biden's running mate, Sen. Kamala Harris talked about what she'll do to fight for women if elected VP, and how the Democrats are thinking about voter turnout strategies ahead of November.

What they're saying: "In a Biden-Harris administration women are going to be a priority, understanding that women have many priorities and all of them must be acknowledged," Harris told The 19th*'s Errin Haines-Whack.
