8 New HTTP/2 Implementation Flaws Expose Websites to DoS Attacks
Aug 14, 2019
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
This $5 Device Can Hack your Password-Protected Computers in Just One Minute
Nov 16, 2016
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.

Employees are covertly using AI with little regard for established IT and cybersecurity review procedures. Considering ChatGPT's meteoric rise to 100 million users within 60 days of launch , especially with little sales and marketing fanfare, employee-driven demand for AI tools will only escalate. As new studies show some workers boost productivity by 40% using generative AI , the pressure for CISOs and their teams to fast-track AI adoption — and turn a blind eye to unsanctioned AI tool usage — is intensifying. But succumbing to these pressures can introduce serious SaaS data leakage and breach risks, particularly as employees flock to AI tools developed by small businesses, solopreneurs, and indie developers.
