By Jeff Horwitz NEW YORK (Reuters) -Meta researchers found that teens who report that Instagram regularly made them feel bad about their bodies saw significantly more “eating disorder adjacent content” than those who did not, according to an internal document reviewed by Reuters. The posts shown to those users featured “prominent display” of chest, buttocks, or thighs, “explicit judgement” about body types and “content related to disordered eating and/or negative body image.”  While such material is not banned on Instagram, the researchers noted that parents, teens and outside experts have told Meta they believe it is potentially harmful to young users.  Meta surveyed 1,149 teens over the course of the 2023-2024 academic year about whether and how often they felt bad about their bodies after using Instagram. Then they manually sampled the content those users saw on the platform over a three-month period. The study showed that for the 223 teens who often felt bad about their bodies after viewing Instagram, “eating disorder adjacent content” made up 10.5% of what they saw on the platform. Among the other teens in the study, such content accounted for only 3.3% of what they saw.  “Teens who reported frequent body dissatisfaction after viewing posts on Instagram… saw about three times more body-focused/ED-adjacent content than other teens,” the authors wrote, referring to eating disorders, according to a summary of the research reviewed exclusively by Reuters. In addition to seeing more eating disorder-adjacent content, researchers found, the teens who reported the most negative feelings about themselves saw more provocative content more broadly, content Meta classifies as “mature themes,”  “Risky behavior,” “Harm & Cruelty” and “Suffering.” Cumulatively, such content accounted for 27% of what those teens saw on the platform, compared with 13.6% among their peers who hadn’t reported negative feelings.  META RESEARCHERS EXPRESSED CONCERN The researchers stressed that their findings did not prove that Instagram was making users feel worse about their bodies. “It is not possible to establish the causal direction of these findings,” they wrote, noting the possibility that teens who felt bad about themselves could be actively seeking out that material.  The Instagram research, a redacted replica of which is published here and has not been previously reported, demonstrated that Instagram exposed teens who “report frequently experiencing body dissatisfaction" to high doses of content that Meta’s own advisors “have expressed support for limiting,” the writeup said. In a statement, Meta spokesperson Andy Stone said the document reviewed by Reuters demonstrates Meta’s commitment to understanding and improving its products.  “This research is further proof we remain committed to understanding young people’s experiences and using those insights to build safer, more supportive platforms for teens,” Stone said, noting the company’s recent announcement that it would attempt to show minors content in-line with PG-13 movie standards.   In the study, Meta said that its existing screening tools – which were designed to catch violations of platform rules – were incapable of detecting 98.5% of the “sensitive” content that the company believes might not have been appropriate for teens. The finding was “not necessarily surprising,” the researchers wrote, because Meta had only recently begun work on building an algorithm to detect the potentially harmful content they were examining. 'ASSOCIATION' BETWEEN CONTENT AND 'FEELING WORSE ABOUT ONE'S BODY' The study, which is marked, “Do not distribute internally or externally without permission,” is the latest internal research that demonstrates an “association” between viewing fashion, beauty and fitness content and “reporting feeling worse about one’s body,” the document states. The research was conducted as part of Meta’s efforts to understand interactions between users and its own products, which rely on algorithms to determine which content to show to users.  In the United States, the company has faced state and federal investigations of Instagram’s effects on children as well as civil suits by school districts alleging harmful product design and deceptive marketing of its platforms as safe for teens.  Those suits have prominently cited past leaked internal research from Meta in which researchers expressed their belief that the platform’s content recommendations might be harmful to youth with existing body image issues.  Since July of this year, Stone said, the company has reduced the amount of age-restricted content shown to teenage Instagram users by half.  CONTENT WARRANTED TRIGGER WARNING Jenny Radesky, a University of Michigan Associate Professor of Pediatrics who reviewed Meta’s unreleased research at Reuters’ request, called the study’s methodology robust and its findings disturbing. “This supports the idea that teens with psychological vulnerabilities are being profiled by Instagram and fed more harmful content,” Radesky said. “We know that a lot of what people consume on social media comes from the feed, not from search.” Past internal research at Meta “has demonstrated an association between frequency of reporting feeling worse about one’s body” and consuming Instagram fitness and beauty content, the writeup says.  Meta’s researchers wrote that teens, parents, pediatricians, external advisors and Meta’s own Eating Disorder & Body Image Advisory Council have urged Instagram to limit how much of that content it shows to teenagers, warning that it “may be detrimental to teen well-being, specifically by precipitating or exacerbating feelings of body dissatisfaction.” Such content falls afoul of Meta’s rules against content that overtly promotes eating disorders. The report included samples of problematic content including images of skinny women in lingerie and bikinis, fight videos and a drawing of a crying figure scrawled with phrases including “how could I ever compare” and “make it all end.” One of the example posts showed a closeup of a woman’s lacerated neck.  Though the content did not violate Meta’s rules, the researchers found it disturbing enough that they issued a “sensitive content” warning to colleagues reading their work.

By Raphael Satter and AJ Vicens WASHINGTON (Reuters) -A more than year-long digital intrusion into cybersecurity company F5, publicized last week and blamed on Chinese spies, has defenders across the industry hunting for signs of compromise among the many corporate networks that use its products. Several worry that more disclosures are coming. So far, little is known about the scope of the hack beyond statements from F5 that its source code and sensitive information about software vulnerabilities were stolen. The company's website says it serves more than four in five Fortune 500 companies in some capacity, and U.S. officials have said that federal networks were among those targeted in the hack's aftermath and have urged immediate action. That extensive presence alone has triggered widespread unease. F5's stock tumbled 12 percent last Thursday, the day it published a host of fixes for previously vulnerable products, although it rebounded slightly by the end of the week. Several cybersecurity executives and analysts compared the hack at F5 to the extraordinary intrusion at the software company SolarWinds discovered in December 2020. That company, whose Orion software was used for network monitoring, became the unwitting springboard into a number of highly sensitive networks after its source code was tampered with. Around a dozen government departments were eventually breached in the wide-ranging spy operation. Just like SolarWinds, which was little known in the consumer market before the hack, F5 has a host of tech equipment and services – load balancers, content delivery networks and firewalls – that typically play low-profile but critical roles in directing, managing and filtering organizations' internet traffic. "I'm not equating this to the SolarWinds attack, but I'm equating it to the fact that people never hear of it, but it's in everybody's network," said Michael Sikorski, the chief technology officer at Palo Alto Networks' threat intelligence-focused Unit 42. "When we're talking about 80 percent of the Fortune 500, we're talking about banks, law firms, tech companies, you name it." Sikorski said the F5 hackers stole source code and undisclosed vulnerability information, potentially giving them the ability to develop tools for cyberespionage in a tight time frame. Bob Huber, chief security officer of cybersecurity firm Tenable, said he too had SolarWinds in mind as he tried to make sense of what was going on at F5. "As of right now, this is not SolarWinds," he told Reuters, noting that F5 has said it had "no evidence of modification to our software supply chain." Still, Huber said there were signs that more unwelcome disclosures lie ahead, given the paucity of information about the breach and the urgency with which the government was moving to remediate it, via an October 15 emergency directive and a public warning that unnamed federal networks were being targeted by a "nation-state cyber threat actor." "We're waiting for the other shoe to drop," he said. While no other victims of the F5 breach have been publicly identified, cybersecurity firm Greynoise Intelligence, which monitors internet scanning and attack activity, has found hints that an unknown actor was searching out F5 devices on the internet starting about a month ago. Greynoise detected a major spike in scanning activity focused on F5 beginning in mid-September, according to Glenn Thorpe, the company's senior director of security research and detection engineering. "That implies someone somewhere knew something," Thorpe said. (Reporting by Raphael Satter and AJ Vicens; Editing by Edmund Klamann)

(Reuters) -Amazon's cloud services unit AWS was hit by an outage on Monday that took down several popular apps including Fortnite and Snapchat and caused connectivity issues for many companies around the world. AWS said it was seeing increased "error rates and latencies" for multiple services. "We are working on multiple parallel paths to accelerate recovery," it said in its latest update. The AWS outage is the first major internet disruption since last year's CrowdStrike malfunction that hobbled technology systems in hospitals, banks and airports globally. AWS provides on-demand computing power, data storage and other digital services to companies, governments and individuals. Disruptions to its servers can cause outages across websites and platforms that rely on its cloud infrastructure. AWS competes with Google's and Microsoft's cloud services. AWS directed Reuters to its status page when requested for a comment. Amazon did not respond to a request for comment. PERPLEXITY, COINBASE, PRIME VIDEO DOWN AI startup Perplexity, cryptocurrency exchange Coinbase and trading app Robinhood attributed the outages to AWS. "Perplexity is down right now. The root cause is an AWS issue. We're working on resolving it," Perplexity CEO Aravind Srinivas said in a post on X. Amazon's shopping website, PrimeVideo and Alexa were all facing issues, according to Downdetector. Fortnite, owned by Epic Games, Roblox, Clash Royale and Clash of Clans were among the gaming platforms that were down, while Paypal's Venmo and Chime were some of the financial platforms that faced issues, the outage tracking website said. Uber rival Lyft's app was also down for thousands of users in the U.S. Messaging app Signal's President Meredith Whittaker confirmed on X that the company's platform was hit by the AWS outage as well. BRITISH FIRMS AFFECTED Britain's Lloyd Bank, Bank of Scotland and telecom service providers Vodafone and BT were also facing issues, according to DownDetecor's UK website. The country's tax, payments and customs authority HMRC's website too was hit by the outage. However, billionaire Elon Musk, the owner of social media company X, said that his platform continued to work. "X works," he said, without commenting further.
