5 High Impact Flaws Affect Cisco Routers, Switches, IP Phones and Cameras

5 High Impact Flaws Affect Cisco Routers, Switches, IP Phones and Cameras

February 05, 2020Swati Khandelwal
Several Cisco-manufactured network equipments have been found vulnerable to five new security vulnerabilities that could allow hackers to take complete control over them, and subsequently, over the enterprise networks they power. Four of the five high-severity bugs are remote code execution issues affecting Cisco routers, switches, and IP cameras, whereas the fifth vulnerability is a denial-of-service issue affecting Cisco IP phones. Collectively dubbed ' CDPwn ,' the reported vulnerabilities reside in the various implementations of the Cisco Discovery Protocol (CDP) that comes enabled by default on virtually all Cisco devices and can not be turned OFF. Cisco Discovery Protocol (CDP) is an administrative protocol that works at Layer 2 of the Internet Protocol (IP) stack. The protocol has been designed to let devices discover information about other locally attached Cisco equipment in the same network. According to a report Armis research team shared with The Hacker N
How Organizations Can Defend Against Advanced Persistent Threats

How Organizations Can Defend Against Advanced Persistent Threats

December 25, 2019The Hacker News
Advanced persistent threats (APTs) have emerged to be legitimate concerns for all organizations. APTs are threat actors that breach networks and infrastructures and stealthily lurk within them over extended spans of time. They typically perform complex hacks that allow them to steal or destroy data and resources. According to Accenture , APTs have been organizing themselves into groups that enable them to share tactics and tools to carry out attacks at scale. Russian group Silence APT, for instance, has been reported to be actively targeting financial institutions and have successfully stolen millions of dollars from various banks worldwide. Smaller organizations also need to be wary of such threats. APT groups also use automated tools and botnets to gain access to networks, and these tactics don't discriminate based on size, industry, or value. Any vulnerable infrastructure can be breached. It is now critical for all organizations to understand how APTs operate and impleme

Gartner Says the Future of Network Security Lies with SASE

Gartner Says the Future of Network Security Lies with SASE

November 07, 2019The Hacker News
Cloud services and networking are driving the concept of digital businesses, yet traditional networking and cybersecurity architectures are far from meeting the demands of the digital business. Gartner's " The Future of Network Security Is in the Cloud " report spells out the potential for the transformation of networking and security in the cloud, built upon a new networking and security model. That model is called Secure Access Service Edge (SASE) , a term coined by Gartner's leading security analysts Neil MacDonald, Lawrence Orans, and Joe Skorupa. Gartner claims that SASE has the potential to invert the established networking and security service stack from one based in the data center into a design that shifts the focal point of identity to the user and the endpoint device. SASE addresses the numerous problems that have been discovered with traditional cybersecurity methods used in the cloud. Many of those problems have roots with the ideology that netwo

How MSPs can become Managed Detection and Response (MDR) Providers

October 29, 2019The Hacker News
Managed detection and response (MDR) is one of the fastest-growing segments in the cybersecurity market. ESG research from April 2019 reveals that 27% of organizations are actively pursuing an MDR project, while another 11% plan to pursue an MDR project in the future. Cynet now enables service providers to add MDR to their portfolio and gain an important competitive advantage over competitors with Cynet 360 integrated offering of breach protection platform and CyOps 24\7 SOC team ( Learn more here ). MDR is a relatively new security service offering that emerged in recent years to assist the standard organization with a team of experts that provide 24\7 alert prioritization, investigation, and proactive threat hunting — tasks that are typically beyond its in-house capabilities. Cynet 360's complete coverage across endpoints, network, and user accounts makes it a tool of choice that provides MDR providers with real-time threat coverage across the entire environment with a

Cynet's Vulnerability Assessment Enables Organizations to Dramatically Reduce their Risk Exposure

October 22, 2019The Hacker News
Protection from cyberattacks begins way before attackers launch their weapons on an organization. Continuously monitoring the environment for security weaknesses and addressing such, if found, is a proven way to provide organizations with immunity to a large portion of attacks. Among the common weaknesses that expose organizations to cyberattacks, the most prominent are software vulnerabilities in systems and applications that attackers relentlessly take advantage of. To assist in the discovery of such vulnerabilities, Cynet now offers organizations a 14 days free access to its Cynet 360 platform in which they can leverage its built-in vulnerability assessment tools. A vulnerability is a bug in the software that enables a threat actor to manipulate it for malicious purposes. For example, a vulnerability in Word enables attackers to craft a Word document in such a manner that when a user double clicks to open it, it transparently opens a connection between the user computer an

Just An SMS Could Let Remote Attackers Access All Your Emails, Experts Warn

September 04, 2019Mohit Kumar
Beware! Billion of Android users can easily be tricked into changing their devices' critical network settings with just an SMS-based phishing attack. Whenever you insert a new SIM in your phone and connects to your cellular network for the very first time, your carrier service automatically configures or sends you a message containing network-specific settings required to connect to data services. While manually installing it on your device, have you ever noticed what configurations these messages, technically known as OMA CP messages, include? Well, believe me, most users never bother about it if their mobile Internet services work smoothly. But you should worry about these settings, as installing untrusted settings can put your data privacy at risk, allowing remote attackers to spy on your data communications, a team of cybersecurity researchers told The Hacker News. Mobile carriers send OMA CP (Open Mobile Alliance Client Provisioning) messages containing APN settin

What could be more horrifying than knowing that a hacker can trick the plane's electronic systems into displaying false flight data to the pilot, which could eventually result in loss of control? Of course, the attacker would never wish to be on the same flight, so in this article, we are going to talk about a potential loophole that could allow an attacker to exploit a vulnerability with some level of "unsupervised" physical access to a small aircraft before the plane takes off. The United States Department of Homeland Security's (DHS) has issued an alert for the same, warning owners of small aircraft to be on guard against a vulnerability that could enable attackers to easily hack the plane's CAN bus and take control of key navigation systems. The vulnerability, discovered by a cybersecurity researcher at Rapid 7, resides in the modern aircraft's implementation of CAN (Controller Area Network) bus—a popular vehicular networking standard used in au

In every organization, there is a person who's directly accountable for cybersecurity. The name of the role varies per the organization's size and maturity – CISO, CIO, and Director of IT are just a few common examples – but the responsibility is similar in all places. They're the person who understands the risk and exposure, knows how prepared the team and most important – what the gaps are and how they can be best addressed. Apart from actually securing the organization – and losing some sleep over it – this individual has another equally important task: to communicate the security risk, needs, and status to the company's management. After all, the level of security rises in direct proportion to the amount of invested resources, and management people are the ones who decide and allocate them. Since management people are not typically cybersecurity savvy, engaging them can be challenging – one must find the balance between high-level explanations, a direct c

High-quality cybersecurity posture is typically regarded as the exclusive domain of the large and heavy resourced enterprises – those who can afford a multi-product security stack and a skilled security team to operate it. This implies a grave risk to all organizations who are not part of this group, since the modern threat landscape applies to all, regardless of size and vertical. What is less commonly known is that by following basic and well-defined practices and wise security product choices, any organization can level up its defenses to a much higher standard. "At the end of the day it comes down to strategic planning," says Eyal Gruner, CEO and co-founder of Cynet, "rather than thinking in term of specific product or need, zoom out and breakdown the challenge to its logical parts – what do you need to do proactively on an on-going basis, while you're under attack and when you manage a recovery process." From the various frameworks of security b

Advanced Breach Protection Demystified – Untold Truths On Security Beyond AV

March 28, 2019The Hacker News
Doing business in today's connected world means dealing with a continually evolving threat landscape. With potential losses due to downtime following a breach, plus valuable client and proprietary information at risk, most organizations realize they cannot afford to be complacent. This puts extra onus on security IT teams, who are continuously left scrambling, looking for the best way to protect their organizations against the threats that bypass AV and firewall. Added to this is another challenge in that most organizations are limited in the resources they can invest in security. Many are left reliant on a single product on top of their security stack. Common practice in organizational security circles as they attempt to remain secure is to upgrade endpoint protection with EPP\EDR or a Network Analytic tool. But as we all know, what's common is not necessarily what's best. How can an organization ensure it remains secure, especially with all that is at stake?
