A stealthy backdoor undetected by antimalware providers is giving unknown attackers complete control over at least 100 Linux servers that appear to be used in business production environments, warn researchers.
In a blog post published Wednesday, Montreal-based GoSecure claimed that a piece of malware dubbed "Chaos" is infecting poorly secured systems by guessing weak passwords protecting secure shell application administrators use to remotely control Unix-based computers. The secure shell, or SSH, accounts being compromised run as root, and this is how the backdoor is able to get such access as well. Normally, firewalls in front of servers block such backdoors from communicating with the outside Internet. Once installed, Chaos bypasses those protections by using what's known as a "raw socket" to covertly monitor all data sent over the network.
"With Chaos using a raw socket, the backdoor can be triggered on ports running an existing legitimate service," Sebastian Feldmann, a master's degree student intern working for GoSecure, wrote. "As an example, a Webserver that would only expose SSH (22), HTTP (80), and HTTPS (443) would not be reachable via a traditional backdoor due to the fact that those services are in use, but with Chaos it becomes possible."

Pretty much any online explainer about high dynamic range TVs (HDR) is hobbled by a not-insignificant asterisk: if you're reading it online, your screen almost certainly can't convey the visual difference. HDR benefits from a full pipeline of newfangled tech to increase color gamut and luminance ranges on screens. In other words, they're brighter and more colorful—and most computer and phone screens can't convey that.
But as it turns out, there's a way, albeit a geeky one, to visually break down both the impact and issues of current-day HDR. As one enterprising gamer found out, the answer is tucked away into every single Xbox One console.
A thread on the renowned gaming forum ResetERA appeared on Thursday with a huge swath of heatmap images from modern HDR-compatible games, all posted by a user with the handle EvilBoris. And as he explains to Ars Technica, these images came about simply out of curiosity.
Customers should be allowed to "choose who they share vehicles with", says Transport for London.
A federal judge in Los Angeles has dismissed a copyright infringement lawsuit filed against Happy Mutants, the parent company of the popular website Boing Boing.
Back in November 2017, Playboy Entertainment Group sued Boing Boing, accusing it of violating the company’s copyright when, in February 2016, the website simply linked to a separate online collection of "Every Playboy Playmate Centerfold Ever." That portfolio, which was hosted on Imgur, has since been removed. Imgur did not immediately respond to Ars’ request for comment.
Because Boing Boing has advertising on its site, Playboy argued, it is profiting from those unauthorized images.
