A new DDoS technique named 'HTTP/2 Rapid Reset' has been actively exploited as a zero-day since August, breaking all previous records in magnitude.Since late August, Cloudflare has detected and mitigated over a thousand 'HTTP/2 Rapid Reset' DDoS attacks that surpassed 10 million rps, with 184 breaking the previous 71 million rps record.
The threat actor known as ChamelGang has been observed using a previously undocumented implant to backdoor Linux systems, marking a new expansion of the threat actor's capabilities. The malware, dubbed ChamelDoH by Stairwell, is a C++-based tool for communicating via DNS-over-HTTPS tunneling.
"Disable HTTP and HTTPS traffic to MOVEit Transfer," says Progress Software, and the timeframe for doing so is "Immediately", no ifs, no buts. Progress Software is the maker of file-sharing software MOVEit Transfer, and the hosted MOVEit Cloud alternative that's based on it, and this is its third warning in three weeks about hackable vulnerabilities in its product.
The Chinese threat group 'ChamelGang' infects Linux devices with a previously unknown implant named 'ChamelDoH,' allowing DNS-over-HTTPS communications with attackers' servers. The link between ChamelGang and the new Linux malware is based on a domain previously associated with the threat actor and a custom privilege elevation tool observed by Positive Technologies in past ChamelGang campaigns.
Logowatch Google plans to retire the padlock icon that appears in the Chrome status bar during a secure HTTPS web browsing session because the interface graphic has outlived its usefulness. Today's Chrome lock icon currently oversees a broad portfolio of functions.
In September 2023, Google Chrome will stop showing the lock icon when a site loads over HTTPS, partly due to the now ubiquitous use of the protocol. "We redesigned the lock icon in 2016 after our research showed that many users misunderstood what the icon conveyed. Despite our best efforts, our research in 2021 showed that only 11% of study participants correctly understood the precise meaning of the lock icon," the team explained.
Web infrastructure company Cloudflare on Monday disclosed that it thwarted a record-breaking distributed denial-of-service attack that peaked at over 71 million requests per second. "The majority of attacks peaked in the ballpark of 50-70 million requests per second with the largest exceeding 71 million," the company said, calling it a "Hyper-volumetric" DDoS attack.
Portainer smooths out the rather steep learning curve of Kubernetes, making it considerably easier for your teams to manage namespaces, networks, pods, ingresses, Helm, ConfigMaps & Secrets, Volumes and even the cluster. My go-to method of deploying Portainer is via a Microk8s cluster, which is the easiest method of getting Kubernetes support rolled into the web-based GUI; however, when deployed in this fashion, Portainer can be accessed either via HTTP or HTTPS and doesn't use SSL certificates.
In this Help Net Security video, Austin Jones, Principal Software Engineer at ThreatX, explains what HTTP request smuggling is, and discusses a recently uncovered HTTP request smuggling vulnerability in Node.js. This vulnerability allows an attacker to bypass security controls on the target server to conduct any nefarious activities.
Cybersecurity company Imperva has disclosed that it mitigated a distributed denial-of-service attack with a total of over 25.3 billion requests on June 27, 2022. The "Strong attack," which targeted an unnamed Chinese telecommunications company, is said to have lasted for four hours and peaked at 3.9 million requests per second.
