UK-based Revolution Beauty said on Monday it could reach a settlement with top shareholder Boohoo over board changes

Former Manchester United executive vice-chair Ed Woodward has accepted a first job since departing Old Trafford last year. Woodward has joined the board of educational esports company EStars as a non-executive director. EStars is “at the heart of the fastest-growing sport in the world”, using esports to bring classmates together, both during and after school hours, to foster great academic goals, inclusion, diversity and positive outcomes. Ex-Newcastle, Netherlands and current Norwich goalkeeper Tim Krul has been a shareholder in the company since its inception in 2017 and Woodward explained his decision to accept the new role. He said: “When you put together esports, education and a dynamic region such as the Middle East, where curriculum decisions can be made faster than Europe, it is a recipe for success. “Joining the team is an easy decision when you add the exceptional leadership and entrepreneurial energy of Mags [founder Mags Byrne]. I’m excited about EStars delivering a path of learning for the next generation in the (relatively) new industry of esports.” Having qualified as a chartered accountant and then worked at JPMorgan as an investment banker, Woodward joined Man United in 2005 to oversee their commercial operations, having advised the Glazer family on their purchase of the club. He was appointed to the board of directors in 2008 and became executive vice-chair in 2013 when David Gill retired. He became an incredibly unpopular figure at Old Trafford due to his association with a Glazer regime that fans turned against and despite the £1bn he sanctioned in transfer fees, his tenure is regarded as a failure, with the club struggling on the pitch – in relative terms at least – in the post-Sir Alex Ferguson era. It has been mooted that he could help the Glazer family negotiate any potential sale of Manchester United as the takeover saga drags on.

Bots are better and significantly faster than humans at cracking Captcha tests, according to a comprehensive new study that inspected the security system deployed in over 100 popular websites. Automated bots pose a significant threat to the internet because they can masquerade as legitimate human users and perform harmful operations like scraping content, creating accounts and posting fake comments or reviews, as well as consuming scarce resources. “If left unchecked, bots can perform these nefarious actions at scale,” warned scientists, including those from the University of California, Irvine. For over two decades, Captchas have been deployed as security checks by websites to block potentially harmful bots by presenting puzzles that are supposed to be straightforward for people to solve – but very difficult for computers. Earlier forms of Captcha, for instance, asked users to transcribe distorted text from an image, but with advances in computer vision and machine learning, bots soon caught up to recognise the text with near perfect accuracy. Engaged in an arms race with bots, Captchas have since evolved into an annoying presence on the internet, becoming increasingly more and more difficult to solve for both bots and humans. However, the new yet-to-be peer-reviewed research, posted in arXiv, finds bots are able to quickly crack Captcha tests with ease, suggesting global effort users put into cracking these puzzles every day may be more trouble than it’s worth. In the study, scientists assessed 200 of the most popular websites and found 120 still used Captcha. They took the help of 1,000 participants online from diverse backgrounds – varying in location, age, sex and educational level – to take 10 captcha tests on these sites and gauge their difficulty levels. Researchers found many bots described in scientific journals could beat humans at these tests in both speed and accuracy. Some captcha tests took human participants between nine and 15 seconds to solve, with an accuracy of about 50 to 84 per cent, while it took the bots less than a second to crack them, with up to near perfection. “The bots’ accuracy ranges from 85-100 per cent, with the majority above 96 per cent. This substantially exceeds the human accuracy range we observed (50-85 per cent),” scientists wrote in the study. They also found that the bots’ solving times are “significantly lower” or nearly the same as humans in almost all cases. Since current Captchas do not meet the required security goal of keeping bots away, researchers have called for better and more dynamic approaches to protect websites.
