Equifax announced Thursday that 2.4 million additional Americans were impacted in the credit reporting agency's 2017 cybersecurity breach. That brings the total number of Americans affected to about 147.9 million in the largest data breach of personal information in history.

The big picture: The newly announced 2.4 million had less vital personal information exposed — their names and partial driver’s license numbers. The original 145.5 million had their Social Security numbers stolen, which can be significantly more damaging in potential identity theft.

The big thing: This new revelation shows how Americans can still be left in the dark about whether their personal information is secure after a data breach — even months after an incident occurs — potentially leaving them vulnerable to identity theft and its related headaches for years to come.

The investigations:

The details for those newly affected:

  • Equifax found the additional 2.4 million exposures by cross-referencing names and partial driver’s license numbers with internal and external data sources.
  • The newly announced 2.4 million will receive the same credit monitoring and identity theft protection Equifax offered those who were alerted in the initial announcement.

Hong Kong media tycoon Jimmy Lai arrested under national security law

Hong Kong pro-democracy activist Jimmy Lai has been arrested for "collusion with foreign powers" and the offices of his newspaper raided, said Mark Simon, an executive at the tycoon's media firm Next Digital on Monday.

Why it matters: He was arrested under the new national security law that gives Beijing more powers over the former British colony. Lai is the most prominent person arrested under the law — which prompted the U.S. to sanction Chinese officials, including Hong Kong leader Carrie Lam, over Beijing's efforts to strip the territory of its autonomy.

At least 97,000 children tested positive for COVID-19 in the final two weeks of July and there's been an estimated 338,000 cases involving kids in the U.S. since the pandemic began, a new report finds.

Why it matters: The findings in the report by the American Academy of Pediatrics and the Children’s Hospital Association comes as schools and day cares look to reopen in the U.S., with New York Gov. Andrew Cuomo (D) announcing Friday that school districts in the state can reopen in the fall amid lower coronavirus transmission rates.
