Facebook finds ‘no evidence’ hackers accessed connected apps

Facebook has said it’s found “no evidence” that third-party apps were affected by the data breach it revealed last week.

Hackers stole account access tokens on at least 50 million users by exploiting a chain of three vulnerabilities inadvertently introduced by Facebook last year. Another 40 million also may have been affected by the attack. Facebook revoked those tokens — which keep users logged in when they enter their username and password — forcing users to log back into the site again.

But there was concern that third-party apps, sites and services that rely on Facebook to log in — like Spotify, Tinder and Instagram — also may have been affected, prompting companies that use Facebook Login to seek answers from the social networking giant.

“We have now analyzed our logs for all third-party apps installed or logged during the attack we discovered last week,” said Guy Rosen, Facebook’s vice president of product management, in a blog post. “That investigation has so far found no evidence that the attackers accessed any apps using Facebook Login.”

“Any developer using our official Facebook SDKs — and all those that have regularly checked the validity of their users’ access tokens – were automatically protected when we reset people’s access tokens,” he said.

Admittedly, Rosen said that not all developers use Facebook’s developer tools, so the social network is “building a tool to enable developers to manually identify the users of their apps who may have been affected, so that they can log them out.”

Facebook didn’t say when the tool would become available. TechCrunch has reached out for comment and will update when we hear back.

The breach affected five million users in Europe, the company confirmed, where data protection laws are stricter and financial penalties are greater.

Under the newly installed General Data Protection Regulation (GDPR), European regulators can fine Facebook up to $1.63 billion in fines — or four percent of its $40.7 billion in annual global revenue for the prior financial year — if it’s found that Facebook could have done more to protect its users’ data.

Here are the newest additions to Microsoft’s Surface line

Want excitement? Here’s something approaching that. Today’s Microsoft October event wasn’t exactly a blockbuster, but product lead Panos Panay did mention that this is the most new Surface products the company has crammed into one event.

There was a lot of stuff to get through in the hour or so — though the majority of the announcements were spec bumps to existing products. In fact, aside from new matte black paint jobs, you wouldn’t really be able to tell the difference here.

That includes the expected lack of USB-C ports on the new products. It’s an odd choice, to say the least — though “oversight” is probably the more operative word here.

As anticipated, the Surface Pro, Laptop and Studio all got spec bumps here. Starting at $999, the Surface Pro 6 is 67 percent faster than its predecessor, by Microsoft’s count. There’s also a 267ppi display and a stated 13.5 hours of battery life. 

The new Surface Laptop (which has been my own personal favorite in the line) gets even bigger bumps. The device is 85 percent faster than the first-gen, courtesy of the 8th-gen Quad Core Intel processor, while the battery should get 14.5 hours on a charge. 

The Studio, arguably the most interesting Surface product to date, features a screen that’s 38 percent brighter, with 22 percent more contrast. Inside are Pascal graphics cards and a 2TB solid state drive.

The Headphones are easily the most interesting announcement of the bunch. One, because the company somehow managed to keep them under wraps until today’s event and two, because Surface Headphones are a bit of a bizarre addition to the line. Even so, I was pretty happy with the brief time I spent with them.

Internet Archive project helps restore millions of broken Wikipedia links

The web, it turns out, is a fragile place. Companies, governments, educational institutions, individuals and organizations put up and take down sites all the time. The problem is that the web has become a system of record, and when links don’t work because pages no longer exist, the record is incomplete. With the help of volunteers from Internet Archive, Wikipedia has been able to recover 9 million broken links and help solve that problem for at least one knowledge base.

The Internet Archive captures a copy of as many websites as it can to build an archive of the web. If you know what you’re looking for, you can search their Wayback Machine archive of more than 338 billion web pages, dating back to the earliest days of the World Wide Web. The problem is you have to know what you’re searching for, and that can be problematic.

A Wikipedia contributor named Maximilian Doerr put the power of software to bear on the problem. He built a program called IAbot, short for Internet Archive bot. Internet Archive also credits Stephen Balbach, who worked with Doerr and the Internet Archive, tracking down and verifying Wikipedia archives and writing programs to fix data errors.

First IAbot identified broken links, those pages that returned a 404 or “page not found” errors. Once the bot identified a broken link, it searched the Internet Archive for the matching page, and when it found a copy, it linked to that, thereby preserving the link to the content, even though the original page or website was no longer available.

Over a three-year period, that software helped fix 6 million links across 22 Wikipedia sites. Wikipedia volunteers fixed an additional 3 million links by manually linking to the correct Internet Archive page, an astonishing amount of preservation work, and one that helps maintain the integrity of the web and provides an audit trail where one was missing.

In a blog post announcing the results of the project, Internet Archive reported that after studying the link-clicking behavior of Wikipedia users over a recent 10-day period, they found that the vast majority of links were going to Internet Archive pages, showing the power of this project to fix broken links in Wikipedia.

A few years ago, I wrote a piece in which I lamented that the internet was failing the website preservation test. I concluded, “If we can send bots out to index the internet, it seems we should be able to find an automated technological solution to preserve content for future generations. At the very least, we are duty bound to try.”

If this is truly our system of record for government and society, then we need more projects like this to preserve the integrity of the system for future generations. The Internet Archive/Wikipedia project is certainly a positive step in that direction. What’s more, the organization plans to build on this work across Wikipedia and other sites, while also working with editors or writers who wish to link to archived pages when live pages no longer exist.

Note: This article originally incorrectly referred to Internet Archive as Internet.org.
