HTTP Strict Transport Security | Breaking Cybersecurity News | The Hacker News

Various implementations of HTTP/2 , the latest version of the HTTP network protocol, have been found vulnerable to multiple security vulnerabilities affecting the most popular web server software, including Apache, Microsoft's IIS, and NGINX. Launched in May 2015, HTTP/2 has been designed for better security and improved online experience by speeding up page loads. Today, over hundreds of millions of websites, or some 40 percent of all the sites on the Internet, are running using HTTP/2 protocol. A total of eight high-severity HTTP/2 vulnerabilities , seven discovered by Jonathan Looney of Netflix and one by Piotr Sikora of Google, exist due to resource exhaustion when handling malicious input, allowing a client to overload server's queue management code. The vulnerabilities can be exploited to launch Denial of Service (DoS) attacks against millions of online services and websites that are running on a web server with the vulnerable implementation of HTTP/2 , knocking...

You need to be more careful next time while leaving your computer unattended at your office, as it cost hackers just $5 and only 30 seconds to hack into any computer. Well-known hardware hacker Samy Kamkar has once again devised a cheap exploit tool, this time that takes just 30 seconds to install a privacy-invading backdoor into your computer, even if it is locked with a strong password. Dubbed PoisonTap , the new exploit tool runs freely available software on a tiny $5/£4 Raspberry Pi Zero microcomputer, which is attached to a USB adapter. The attack works even if the targeted computer is password-protected if a browser is left open in the computer's background. All an attacker need is to plug the nasty device in the target computer and wait. Here's How PoisonTap works: Once plugged into a Windows or Mac computer via USB port, the tiny device starts impersonating a new ethernet connection. Even if the victim's device is connected to a WiFi network, Poi...

Everybody knows browser extensions are embedded into nearly every user's daily workflow, from spell checkers to GenAI tools. What most IT and security people don't know is that browser extensions' excessive permissions are a growing risk to organizations. LayerX today announced the release of the Enterprise Browser Extension Security Report 2025 , This report is the first and only report to merge public extension marketplace statistics with real-world enterprise usage telemetry. By doing so, it sheds light on one of the most underestimated threat surfaces in modern cybersecurity: browser extensions. The report reveals several findings that IT and security leaders will find interesting, as they build their plans for H2 2025. This includes information and analysis on how many extensions have risky permissions, which kinds of permissions are given, if extension developers are to be trusted, and more. Below, we bring key statistics from the report. Highlights from the Enterprise Browse...

Webmasters can track all your activities on the Internet – even if you have already cleared your browsing history and deleted all saved cookies. A researcher demonstrated two unpatched flaws that can be exploited to track Millions of Internet users, allowing malicious website owners: List Building: To compile a list of visited domains by users, even if they have cleared their browsing history Tracking Cookies: To tag users with a tracking cookie that will persist even after they have deleted all cookies These two Browser Fingerprinting techniques abuse HTTP Strict Transport Security (HSTS) and Content Security Policy – new security features already built into Mozilla Firefox and Google Chrome, and expected to make their ways to other mainstream browsers in near future. WHAT IF, The Website owners turn these Security features against You? A security researcher has proved exactly the same last weekend at Toorcon security conference in San Diego. Yan Zhu...
