Scanning tool | Breaking Cybersecurity News | The Hacker News

Yahoo! has open-sourced Gryffin – a Web Application Security Scanner – in an aim to improve the safety of the Web for everyone. Currently in its beta, Project Gryffin has made available on Github under the BSD-style license that Yahoo! has been using for a number of its open-sourced projects. Gryffin is basically a Go & JavaScript platform that helps system administrators scan URLs for malicious web content and common security vulnerabilities, including SQL Injection and Cross-Site Scripting (XSS) . Yahoo! describes Gryffin as a large-scale Web security scanning platform, which is more than just a scanner, as it is designed to address two specific problems: Coverage Scale Scale is obviously implied for large Web, while Coverage has two dimensions – Crawl and Fuzzing . Crawl's ability is to find as much of the Web application's footprint as possible, whereas Fuzzing involves testing each part of the application's components for an applied se...

Android -  a widely used Smartphone platform offered by Google is once again suspected to affect its users with malicious software that puts their android devices at risk. This time the vulnerabilities occur in the way Android handle the updates to add new flavors to your device. Researchers from Indiana University and Microsoft have discovered [ Paper PDF ] a new set of Android vulnerabilities that is capable to carry out privilege escalation attacks because of the weakness in its Package Management Service (PMS) that puts more than one billion Android devices at risk. The researchers dubbed the new set of security-critical vulnerabilities as Pileup flaws which is a short for privilege escalation through updating, that waylays inside the Android PMS and intensifies the permissions offered to malicious apps whenever an android update occurs, without informing users. The research was carried out by Indiana University Bloomington researchers, Luyi Xing, Xiaorui Pa

As a relatively new security category, many security operators and executives I've met have asked us "What are these Automated Security Validation (ASV) tools?" We've covered that pretty extensively in the past, so today, instead of covering the " What is ASV?" I wanted to address the " Why ASV?" question. In this article, we'll cover some common use cases and misconceptions of how people misuse and misunderstand ASV tools daily (because that's a lot more fun). To kick things off, there's no place to start like the beginning. Automated security validation tools are designed to provide continuous, real-time assessment of an organization's cybersecurity defenses. These tools are continuous and use exploitation to validate defenses like EDR, NDR, and WAFs. They're more in-depth than vulnerability scanners because they use tactics and techniques that you'll see in manual penetration tests. Vulnerability scanners won't relay hashes or combine vulnerabilities to further attacks, whic

Tor is one of the best and freely available privacy software that lets people communicate anonymously online through a series of nodes that is designed to provide anonymity for users and bypass Internet censorship. When you use the Tor software, your IP address remains hidden and it appears that your connection is coming from the IP address of a Tor exit relay or nodes , which can be anywhere in the world. An exit relay is the final relay that Tor traffic passes through before it reaches its destination. According to a recent report ' Spoiled Onions: Exposing Malicious Tor Exit Relays ', published by security researchers Phillip Winter and Stefan Lindskog revealed that almost 20 exit relays in the Tor anonymity network that attempted to spy on users' encrypted traffic using man-in-the-middle techniques. Both Researchers spent more than four months studying on the Tor exit nodes using their own scanning software called " exitmap " and detected su...
