Equifax learned about a massive breach of its systems in March, which a source "familiar with the situation" said was perpetrated by the same intruders that were responsible for the massive breach in July, according to Bloomberg.

What they're saying: In a statement, the company said the March incident was unrelated to the July hack that exposed personal identifying information of up to 143 million Americans. Equifax hired Mandiant, a security firm, in March and again recently to assess the July breach, according to Equifax.

In March, the U.S. Computer Emergency Readiness Team identified the vulnerability exposed in the July hack. Equifax worked to patch that vulnerability, the company said last Friday.

Worth noting: Equifax has said three executives who sold a combined $1.8 million in stock after the July breach weren't aware of any breaches before taking that step. Bloomberg notes that the new revelations could make that harder to argue.

A massive wildfire that prompted mandatory evacuations in Southern California over the weekend burned 26,450 acres and was 5% contained by Monday afternoon, the California Department of Forestry and Fire Protection said.

The big picture: As California remains an epicenter of the coronavirus pandemic in the U.S., some 15 separate fires are raging across the state. About 7,800 people were under evacuation orders from the Apple Fire, about 75 miles east of Los Angeles, as hundreds of firefighters battled the blaze. CalFire said Monday that a malfunction involving a "diesel-fueled vehicle emitting burning carbon from the exhaust system" started the Apple Fire.

The Federal Trade Commission has accused Twitter of using phone numbers and emails from its users to make targeted ads between 2013 and 2019, Twitter said in an SEC filing published Monday.

Why it matters: Twitter estimates that the FTC's draft complaint, which was sent a few days after its Q2 earnings report, could cost the company between $150 million and $250 million. The complaint is unrelated to the recent Twitter hack involving a bitcoin scam.
