Four thousand websites, including those of the U.S. federal court system, the British National Health system and other government sites, have infected visitors with cryptocurrency mining malware, the U.K. National Cyber Security Centre said Monday.

What actually happened? Hackers embedded the CoinHive malware in a third party component, Texthelp Browsealoud, advertised as adding speech, reading, and translation software to websites "for people with Dyslexia, Low Literacy, English as a Second Language, and those with mild visual impairments."

It's not good, but not the worst: CoinHive forces computers to generate cryptocurrency. It's an intensive process and an invasion of a private space, but not the worst thing the attackers could have done.

  • Researcher Scott Helm, who discovered the malware on the sites over the weekend, tweeted:

Minus the jargon, Scott is saying that the attackers could have installed malware that more invasively violated user privacy or used victims to launch even more destructive attacks.

Elevator anxiety will stifle reopenings

Will you step back into an elevator any time soon?

Why it matters: Tens of billions of dollars — and the future of cities around the country — rest on the answer to that question. So long as workers remain unwilling to take elevators, hundreds of billions of dollars' worth of office real estate will continue to go largely unused.

Brazil coronavirus death toll tops 100,000 and case numbers surpass 3 million

Brazilian President Jair Bolsonaro posted a photo of himself to Facebook congratulating his soccer team, Palmeiras, for winning the state title Saturday, moments after the health ministry confirmed the national COVID-19 death toll had surpassed 100,000.

Why it matters: Brazil is only the second country to confirm more than 100,000 deaths from the coronavirus. On Sunday morning, it became the second country to surpass 3 million cases, per Johns Hopkins. Only the U.S. has reported more. Bolsonaro has yet to address the milestones. He has previously tested positive for COVID-19 three times, but he's downplayed the impact of the virus, which has crippled Brazil's economy.
