bash exploit code | Breaking Cybersecurity News | The Hacker News

A recently discovered hole in the security of the Bourne-Again Shell (bash) has the majority of Unix/Linux (including OS X) admins sweating bullets. You should be, too--attackers have already developed exploits to unleash on unpatched web servers, network services and daemons that use shell scripts with environment variables ( this can include network equipment, industrial devices, etc .) Jaime Blasco , AlienVault Labs Director, gives a good explanation of the exploit in this blog post . And, the video below gives you a quick overview of how AlienVault Unified Security Management (USM)  can detect malicious traffic on your network trying to locate and exploit this vulnerability. Basically, this vulnerability allows an attacker to execute shell commands on a server due to an issue in how bash interprets environment variables (such as "cookie", "host", "referrer"). Exploiting this allows an attacker to run shell commands directly. Once they have access to run shell comm

A Critical remotely exploitable vulnerability has been discovered in the widely used Linux and Unix command-line shell, known as Bash , aka the GNU Bourne Again Shell , leaving countless websites, servers, PCs, OS X Macs, various home routers, and many more open to the cyber criminals. Earlier today, Stephane Chazelas publicly disclosed the technical details of the remote code execution vulnerability in Bash which affects most of the Linux distributions and servers worldwide. REMOTELY EXPLOITABLE SHELLSHOCK The vulnerability (CVE-2014-6271) affects versions 1.14 through 4.3 of GNU Bash and being named as Bash Bug , and Shellshock by the Security researchers on the Internet discussions. According to the technical details, a hacker could exploit this bash bug to execute shell commands remotely on a target machine using specifically crafted variables. " In many common configurations, this vulnerability is exploitable over the network, " Stephane said. This 22-ye

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint . Unprotected endpoints provide vulnerable entry points to launch devastating cyberattacks. With IT teams needing to protect more endpoints—and more kinds of endpoints—than ever before, that perimeter has become more challenging to defend. You need to improve your endpoint security, but where do you start? That's where this guide comes in.  We've curated the top 10 must-know endpoint security tips that every IT and security professional should have in their arsenal. From identifying entry points to implementing EDR solutions, we'll dive into the insights you need to defend your endpoints with confidence.  1.
