Technology giants increasingly are casting themselves as defenders of online integrity as American democracy, yet again, comes under attack. A recent string of revelations from companies including Facebook, Microsoft and Google about foreign hacking and disinformation amount to a public answer to charges that the technology industry should have done more to thwart Russia’s online attacks in 2016.

Facebook has begun to assign its users a reputation score, predicting their trustworthiness on a scale from zero to 1. The previously unreported ratings system, which Facebook has developed over the past year, shows that the fight against the gaming of tech systems has evolved to include measuring the credibility of users to help identify malicious actors. Facebook developed its reputation assessments as part of its effort against fake news, Tessa Lyons, the product manager who is in charge of fighting misinformation, said in an interview.

At least three groups that Facebook banned recently for spreading disinformation shared similar names and traits with Twitter accounts that had been linked publicly to Russia earlier this year, underscoring the challenges of swiftly shutting down a foreign influence campaign even once strong hints emerge of who is behind it. Facebook’s handling of the situation underscores the nation’s struggles to respond to credible reports of disinformation two years after the first signs that Russians were seeking to manipulate the 2016 presidential election.

Political strategists say recent moves by Facebook to secure its powerful advertising engine are hampering their ability to communicate with Hispanics and Spanish-speaking audiences ahead of the midterm elections.

Left-leaning political activists accused Facebook of suppressing free speech when the social media giant removed an event listing that it said was part of a new disinformation campaign with ties to Russia.Facebook said it had to act quickly to disclose that inauthentic operators were behind an upcoming event in Washington (DC) to counter a white supremacist rally inspired by Charlottesville.

Facebook has obtained a license to set up an office in China — a first for the social media giant, which has been shut out of China's lucrative market for years despite many attempts to break in. The $30-million subsidiary, which will open in the southern city of Hangzhou, would be set up as a start-up incubator, making minor investments and advising small businesses, according to a person familiar with the company's thinking and a Chinese business filing.

Apparently, a federal investigation into Facebook’s sharing of data with political consultancy Cambridge Analytica has broadened to focus on the actions and statements of the tech giant and involves three agencies, including the Securities and Exchange Commission. Representatives for the FBI, the SEC and the Federal Trade Commission have joined the Justice Department in its inquiries about the two companies and the sharing of personal information of 71 million Americans, suggesting the wide-ranging nature of the investigation, apparently.

Silicon Valley companies and law enforcement are starting to talk about how to ward off meddling by malicious actors including Russia on social media in the November midterms, an attempt at dialogue and information-sharing that was absent during the 2016 presidential elections.

The tech industry’s engineers and entrepreneurs saw the Facebook hearings as more than just the grilling of one of its stars.  To them, the congressional criticism against Facebook chief executive Mark Zuckerberg felt like a referendum on the industry itself and on the social network’s growth-at-any-cost playbook that hundreds of start-ups have sought to emulate over the last decade — and that some have turned against.

The data on millions of Facebook users that a firm wrongfully swiped from the social network probably has spread to other groups, databases and the dark Web, experts said, making Facebook’s pledge to safeguard its users’ privacyhard to enforce. Paul-Olivier Dehaye, a privacy expert and co-founder of PersonalData.IO suspects the data has already proliferated far beyond Cambridge Analytica’s reach. “It is the whole nature of this ecosystem,” Dehaye said. “This data travels.
