Malware Exploits SHELLSHOCK Vulnerability to Hack NAS Devices

Malware Exploits SHELLSHOCK Vulnerability to Hack NAS Devices

Dec 16, 2014
The year is about to end, but serious threats like  Shellshock is " far from over ". Cyber criminals are actively exploiting this critical GNU Bash vulnerability to target those network attached storage devices that are still not patched and ready for exploitation. Security researchers have unearthed a malicious worm that is designed to plant backdoors on network-attached storage (NAS) systems made by Taiwan-based QNAP and gain full access to the contents of those devices. The worm is spread among QNAP devices, which run an embedded Linux operating system, by the exploitation of the GNU Bash vulnerability known as ShellShock or Bash, according to security researchers at the Sans Institute. QNAP vendor released a patch in early October to address the flaw in its Turbo NAS product, but because the patches are not automatic or easy to apply for many users, so a statistically significant portion of systems remain vulnerable and exposed to the Bash bug .

BASHLITE Malware leverages ShellShock Bug to Hijack Devices Running BusyBox

BASHLITE Malware leverages ShellShock Bug to Hijack Devices Running BusyBox

Nov 17, 2014
Cyber criminals are using new malware variants by exploiting GNU Bash vulnerability referred to as ShellShock ( CVE-2014-6271 ) in order to infect embedded devices running BusyBox software, according to a researcher. A new variant of " Bashlite " malware targeting devices running BusyBox software was spotted by the researchers at Trend Micro shortly after the public disclosure of the ShellShock vulnerability. BusyBox provides set of command line utilities that are specifically designed to run in constrained embedded environments. At compile time, different capabilities can be left out, reducing the size of the binaries, and efforts are made to make them memory efficient. This makes the software an excellent candidate for use in consumer electronics devices, which seem to have been the items of interest in this case. The malware variant, detected as ELF_BASHLITE.A (ELF_FLOODER.W) , when executed on victim's machine, scans compromised networks for device
Sailing the Seven Seas Securely from Port to Port – OT Access Security for Ships and Cranes

Sailing the Seven Seas Securely from Port to Port – OT Access Security for Ships and Cranes

Oct 28, 2024Operational Technology / Cybersecurity
Operational Technology (OT) security has affected marine vessel and port operators, since both ships and industrial cranes are being digitalized and automated at a rapid pace, ushering in new types of security challenges. Ships come to shore every six months on average. Container cranes are mostly automated. Diagnostics, maintenance, upgrade and adjustments to these critical systems are done remotely, often by third-party vendor technicians. This highlights the importance of proper secure remote access management for industrial control systems (ICS).  Learn more in our Buyer's Guide for Secure Remote Access Lifecycle Management .  We at SSH Communications Security (SSH) have been pioneering security solutions that bridge the gap between IT and OT in privileged access management . Let's investigate how we helped two customers solve their critical access control needs with us.

POODLE SSL 3.0 Attack Exploits Widely-used Web Encryption Standard

POODLE SSL 3.0 Attack Exploits Widely-used Web Encryption Standard

Oct 15, 2014
Another Heartbleed-like vulnerability has been discovered in the decade old but still widely used Secure Sockets Layer ( SSL ) 3.0 cryptographic protocol that could allow an attacker to decrypt contents of encrypted connections to websites. Google's Security Team revealed on Tuesday that the most widely used web encryption standard SSL 3.0 has a major security vulnerability that could be exploited to steal sensitive data. The flaw affects any product that follows the Secure layer version 3, including Chrome, Firefox, and Internet Explorer. Researchers dubbed the attack as " POODLE ," stands for Padding Oracle On Downgraded Legacy Encryption , which allows an attacker to perform a man-in-the-middle attack in order to decrypt HTTP cookies. The POODLE attack can force a connection to "fallback" to SSL 3.0, where it is then possible to steal cookies, which are meant to store personal data, website preferences or even passwords.

Apple — Most Mac OS X Users Not Vulnerable to 'Shellshock' Bash Bug

Apple — Most Mac OS X Users Not Vulnerable to 'Shellshock' Bash Bug

Sep 27, 2014
On one hand where more than half of the Internet is considering the Bash vulnerability to be severe, Apple says the vast majority of Mac computer users are not at risk from the recently discovered vulnerability in the Bash command-line interpreter – aka the " Shellshock " bug that could allow hackers to take over an operating system completely. Apple has issued a public statement in response to this issue, assuring its OS X users that most of them are safe from any potential attacks through the ShellShock Vulnerability , which security experts have warned affect operating systems, including Mac's OS X. " The vast majority of OS X users are not at risk to recently reported bash vulnerabilities ," Apple said. " Bash, a UNIX command shell and language included in OS X, has a weakness that could allow unauthorized users to remotely gain control of vulnerable systems. With OS X, systems are safe by default and not exposed to remote exploits of bash unl
Hackers Using 'Shellshock' Bash Vulnerability to Launch Botnet Attacks

Hackers Using 'Shellshock' Bash Vulnerability to Launch Botnet Attacks

Sep 27, 2014
Researchers on Thursday discovered a critical remotely exploitable vulnerability in the widely used command-line shell GNU Bourne Again Shell ( Bash ), dubbed " Shellshock " which affects most of the Linux distributions and servers worldwide, and may already have been exploited in the wild to take over Web servers as part of a botnet that is currently trying to infect other servers as well. BOTNET ATTACK IN THE WILD The bot was discovered by the security researcher with the Twitter handle @yinettesys , who reported it on Github and said it appeared to be remotely controlled by miscreants, which indicates that the vulnerability is already being used maliciously by the hackers. The vulnerability (CVE-2014-6271) , which came to light on Wednesday, affects versions 1.14 through 4.3 of GNU Bash and could become a dangerous threat to Linux/Unix and Apple users if the patches to BASH are not applied to the operating systems. However, the patches for the vulnerabil
Remotely Exploitable 'Bash Shell' Vulnerability Affects Linux, Unix and Apple Mac OS X

Remotely Exploitable 'Bash Shell' Vulnerability Affects Linux, Unix and Apple Mac OS X

Sep 25, 2014
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
