A Chinese espionage group appears to have hacked 10 international cellphone providers to track calling data on 20 dissidents, military officials, spies and law enforcement agents, according to a report from the cybersecurity firm Cybereason reported on in the Wall Street Journal.

Why it matters: Though we don't have any details on who the victims are or exactly why they were targeted, China could potentially use tracked phone records to tell if a highly placed individual was another country's intelligence asset or follow the movements of an activist.

Details: The campaign, which Cybereason has dubbed "Operation Soft Cell," did not appear to have targeted any U.S. carriers.

  • Cybereason believes this to be the work of a group known as APT10 due to the hackers following that group's playbook and using the same tools as the group has in the past.
  • While APT10 — also known as Cloud Hopper — had an overwhelming amount of access to carrier networks, the goal appears to have been to steal data.

Context: Cybereason became aware of the campaign in 2018, when it helped a carrier fend off multiple waves of hacking from the group.

  • China is no stranger to monitoring communications providers to harvest details on individuals it sees as a risk. In 2010, the country is believed to have hacked Google to monitor the activity of human rights activists on the platform.

Jan. 6 panel subpoenas 2 far-right "America First" activists

The House select committee investigating the Capitol riot issued subpoenas Wednesday for far-right leaders Nick Fuentes and Patrick Casey, who allegedly encouraged followers to go to D.C. and challenge the 2020 election results.

Why it matters: The action underscores the panel's increasing focus on rallies held ahead of the Capitol attack and how extremists were drawn to former President Trump's baseless claims of widespread voter fraud, per the New York Times.

Democrats fail to change Senate rules to pass voting rights bill

Democrats failed Wednesday night to change Senate filibuster rules to pass the voting rights bill, with Sens. Joe Manchin (D-W.Va.) and Kyrsten Sinema (D-Ariz.) voting with Republicans.

The big picture: The failed effort came after Senate Republicans blocked the voting rights measure from coming to a final vote earlier Wednesday.

Supreme Court rejects Trump's attempt to shield documents from Jan. 6 committee

The Supreme Court rejected on Wednesday night a bid by former President Trump to block the release of documents and records from his administration to the House committee investigating the Jan. 6 riot at the Capitol.

Why it matters: Trump asked the Supreme Court to step in and block the release of the documents last month after a panel on the U.S. Court of Appeals for the D.C. Circuit unanimously denied his attempt to prevent the committee from obtaining the materials.
