“A member of the Stanford Behavioral Laboratory posted on a Prolific forum, “We have noticed a huge leap in the number of participants on the platform in the US Pool, from 40k to 80k. Which is great, however, now a lot of our studies have a gender skew where maybe 85% of participants are women. Plus the age has been averaging around 21.” Wayne State psychologist Hannah Schechter seems to have been the first person to crack the case. “This may be far-fetched,” she tweeted, linking to Frank’s video, “but given the timing, virality of the video, and the user’s follower demographics….” Long-standing Prolific survey-takers complained on Reddit that Frank had made it difficult to find paid surveys to take on the overrun platform.”

Facebook Knows Instagram Is Toxic for Teen Girls, Company Documents Show

15 septembre 2021 /

“They came to the conclusion that some of the problems were specific to Instagram, and not social media more broadly. That is especially true concerning so-called social comparison, which is when people assess their own value in relation to the attractiveness, wealth and success of others. “Social comparison is worse on Instagram,” states Facebook’s deep dive into teen girl body-image issues in 2020, noting that TikTok, a short-video app, is grounded in performance, while users on Snapchat, a rival photo and video-sharing app, are sheltered by jokey filters that “keep the focus on the face.” In contrast, Instagram focuses heavily on the body and lifestyle.”

“The AI Incident Database is a collection of harms or near harms realized in the real world by the deployment of intelligent systems. You are invited to submit reports to the database, whereupon accepted incidents will be indexed and made discoverable to people developing and deploying the next generation of AI technology to the world. Artificial intelligence will only be a benefit to people and society if we collectively record and learn from its failings.”

Exploiting vulnerabilities in Cellebrite UFED and Physical Analyzer from an app’s perspective

FFmpeg vulnerabiltiies by year

“Given the number of opportunities present, we found that it’s possible to execute arbitrary code on a Cellebrite machine simply by including a specially formatted but otherwise innocuous file in any app on a device that is subsequently plugged into Cellebrite and scanned. There are virtually no limits on the code that can be executed. For example, by including a specially formatted but otherwise innocuous file in an app on a device that is then scanned by Cellebrite, it’s possible to execute code that modifies not just the Cellebrite report being created in that scan, but also all previous and future generated Cellebrite reports from all previously scanned devices and all future scanned devices in any arbitrary way (inserting or removing text, email, photos, contacts, files, or any other data), with no detectable timestamp changes or checksum failures. This could even be done at random, and would seriously call the data integrity of Cellebrite’s reports into question.”

Facebook has been autogenerating pages for white supremacists

30 mars 2021 /

Facebook CEO Mark Zuckerberg testifying before Congress in April 2018. It wasn't his only appearance in DC this decade.

“A total of 113 white supremacist organizations and groups had a presence on Facebook, sometimes more than one. One user-generated page that has been active for over a decade had 42,000 likes. Ten other pages and one group had more than 1,000 likes each.Much of Facebook’s moderation system relies on artificial intelligence to flag potential violations for human moderators, a system that appears to be easily thwarted. Simple misspellings of words—whether by adding vowels or using $ in place of S, for example—have been enough to foil algorithmic moderation.”

“Sadly, despite the team’s groundbreaking technical achievements over the last 9 years — doing many things previously thought impossible, like precisely navigating balloons in the stratosphere, creating a mesh network in the sky, or developing balloons that can withstand the harsh conditions of the stratosphere for more than a year — the road to commercial viability has proven much longer and riskier than hoped. So we’ve made the difficult decision to close down Loon. In the coming months, we’ll begin winding down operations and it will no longer be an Other Bet within Alphabet.”

Après plusieurs désastres, Uber met un « stop » à la conduite autonome

8 décembre 2020 /

“Uber et la conduite autonome, c’est terminé. Dans un communiqué publié le 7 décembre, la startup Aurora a annoncé l’acquisition d’Advanced Technologies Group, la division d’Uber dédiée au développement de la conduite autonome. Ces derniers mois, la structure n’a pas été épargnée entre l’accident mortel pendant un test et la condamnation d’un ingénieur accusé de vol industriel et de pratiques déloyales pour embaucher ses anciens collègues de Google (très investi dans la conduite autonome).”

“Twitter it was looking into why the neural network it uses to generate photo previews apparently chooses to show white people’s faces more frequently than Black faces. Several Twitter users demonstrated the issue over the weekend, posting examples of posts that had a Black person’s face and a white person’s face. Twitter’s preview showed the white faces more often.”

“Social Data retourne la responsabilité aux victimes : « les utilisateurs qui ne souhaitent pas donner leurs informations passent leurs profils en privé ». Ce raisonnement technique ne correspond pas à la réalité légale, notamment en Europe, où le RGPD protège les données personnelles des résidents contre leur traitement sans consentement préalable.”
