Hello, everyone. I’m Natasha Singer, your data privacy correspondent. I devote most of my waking hours to delving into the consequences of digital technologies for society and democracy. I even spent my summer vacation teaching a tech-innovation ethics course for high schoolers attending the School of The New York Times, our precollege program.

So it was quite something for me just trying to keep up with all the developments of the week.

To recap: Microsoft said Monday that it had found and shut down fraudulent sites that were imitating those of two conservative American think tanks that promote democracy. The phony sites, which were created by hackers linked to a Russian military intelligence unit, indicated that the Kremlin was widening its attacks beyond deceiving voters, my colleagues David E. Sanger and Sheera Frenkel wrote.

Then on Tuesday, Facebook said it had identified and purged 652 fraudulent accounts, pages and groups that were trying to spread disinformation. This time the campaigns were aimed at tricking people not just in the United States, but also in Britain, Latin America and the Middle East. And in addition to Russia, there was a new misinformation culprit on Facebook’s radar: Iran.
