DUHK — Don't Use Hard-coded Keys — is a new 'non-trivial' cryptographic implementation vulnerability that could allow attackers to recover encryption keys that secure VPN connections and web browsing sessions. DUHK is the third crypto-related vulnerability reported this month after KRACK Wi-Fi attack and ROCA factorization attack . The vulnerability affects products from dozens of vendors, including Fortinet , Cisco, TechGuard, whose devices rely on ANSI X9.31 RNG — an outdated pseudorandom number generation algorithm — 'in conjunction with a hard-coded seed key.' Before getting removed from the list of FIPS-approved pseudorandom number generation algorithms in January 2016, ANSI X9.31 RNG was included into various cryptographic standards over the last three decades. Pseudorandom number generators (PRNGs) don't generate random numbers at all. Instead, it is a deterministic algorithm that produces a sequence of bits based on initial secret values called a

It's been close to five years since we last looked at Incapsula , a security-focused CDN service known for its DDoS mitigation and web application security features. As one would expect, during these five years the company has expanded and improved, introducing lots of new features and even several new products. Most recently, Incapsula underwent an extensive network expansion that includes new PoPs in Asia including two new data centers in New Delhi and Mumbai. This seems like an excellent opportunity to revisit the service and see how it has evolved. Acquisition, Award and Growth Before we jump into Incapsula's service upgrades, we want to mention the changes in the company itself briefly. The most notable of those is Incapsula's 2014 acquisition by Imperva—an authority in web application security and a four-time Gartner Magic Quadrant leader for web application firewalls. The acquisition boosted Incapsula's security capabilities, resulting in its own cloud

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

One of the most devastating aspects of the recent WannaCry ransomware attack was its self-propagating capability exploiting a vulnerability in the file access protocol, SMB v1. Most enterprises defences are externally-facing, focused on stopping incoming email and web attacks. But, once attackers gain a foothold inside the network through malware, there are very few security controls that would prevent the spread of the attack between enterprise locations in the Wide Area Network (WAN). This is partly due to the way enterprises deploy security tools, such as IPS appliances, and the effort needed to maintain those tools across multiple locations. It's for those reasons Cato Networks recently introduced a context-aware Intrusion Prevention System (IPS) as part of its secure SD-WAN service . There are several highlights in this announcement that challenge the basic concept of how IT security maintains an IPS device and sustains the effectiveness of its protection. Cato Network

Admit it. Who would not want their firewall maintenance grunt work to go away? For more than 20 years, companies either managed their edge firewall appliances or had service providers rack-and-stack appliances in their data centers and did it for them. This was called a managed firewall — an appliance wrapped with a managed service, often from a carrier or managed security service provider (MSSP). The provider assumed the management of the firewall box, its software, and even its policy and management from the over-burdened IT team. But customers ended up paying for the inefficiency of dealing with appliances (i.e. "grunt work") because the problem just shifted to the provider. A new architecture was needed - a transformation from an appliance form factor to a true cloud service. In a 2016 Hype Cycle for Infrastructure Protection report , Gartner analyst Jeremy D'Hoinne initiated the emerging category of Firewall as a Service (FWaaS). He defined FWaaS as " ...a fire

WikiLeaks has published a new batch of the ongoing Vault 7 leak , this time detailing a framework – which is being used by the CIA for monitoring the Internet activity of the targeted systems by exploiting vulnerabilities in Wi-Fi devices. Dubbed " Cherry Blossom ," the framework was allegedly designed by the Central Intelligence Agency (CIA) with the help of Stanford Research Institute (SRI International), an American nonprofit research institute, as part of its 'Cherry Bomb' project. Cherry Blossom is basically a remotely controllable firmware-based implant for wireless networking devices, including routers and wireless access points (APs), which exploits router vulnerabilities to gain unauthorized access and then replace firmware with custom Cherry Blossom firmware. "An implanted device [ called Flytrap ] can then be used to monitor the internet activity of and deliver software exploits to targets of interest." a leaked CIA manual  reads . "The wi

Nobody likes to do router and firewall management. It often requires a lot of hard labor just keeping the infrastructure up and running. If you ever had to set up IPsec tunnels between different firewall brands, change a firewall rule and hope nothing breaks, upgrade to the latest software or urgently patch a vulnerability – you know what I am talking about. All of these issues have been with us basically forever. Recently, the list of complex tasks extended to getting cloud infrastructure connected to the rest of the network, and secure access for mobile users. There seems to be a change coming to this key part of IT, a silver lining if you will. We decided to take a look at one solution to this problem – the Cato Cloud from Cato Networks. Founded in 2015, Cato Networks provides a software-defined and cloud-based secure enterprise network that connects all locations, people and data to the Cato Cloud – a single, global, and secure network. Cato promises to simplify netwo

This newly discovered bugs in Java and Python is a big deal today. The two popular programming languages, Java and Python, contain similar security flaws that can be exploited to send unauthorized emails and bypass any firewall defenses. And since both the flaws remain unpatched, hackers can take advantage to design potential cyber attack operations against critical networks and infrastructures. The unpatched flaws actually reside in the way Java and Python programming languages handle File Transfer Protocol (FTP) links, where they don't syntax-check the username parameter, which leads to, what researchers call, protocol injection flaw. Java/Python FTP Injection to Send Unauthorized SMTP Emails In a blog pos t published over the past week, security researcher Alexander Klink detailed the FTP protocol injection vulnerability in Java's XML eXternal Entity (XXE) that allows attackers to inject non-FTP malicious commands inside an FTP connection request. To demonst

It's 2017, and we're not any further along with Wi-Fi security than we were 10 years ago. There are Intrusion Detection Systems and 2nd generation antivirus apps to protect us from some vulnerabilities but the simple fact that some people and businesses still don't set their network up well in the first place. Installing WiFi is like running Ethernet to your parking lot. It's a cliche thing to say, but it is often true. If I can attack your network sitting in my car from the parking lot, what chance do you have? And 99% of the time I'm successful. Lots of companies are moving to new offices that have wide open office layouts. Some may not have BYOD policies or wireless security plans in place, and anyone can bring their own device to work that you may not know about. I've even seen some companies installing IoT devices like smart led light bulbs and thermostats. Even some security camera systems which are always running unsecured and default passwords. So what can you

A proof-of-concept (PoC) exploit for a critical vulnerability in the Network Time Protocol daemon (ntpd) has been publically released that could allow anyone to crash a server with just a single maliciously crafted packet. The vulnerability has been patched by the Network Time Foundation with the release of NTP 4.2.8p9, which includes a total of 40 security patches, bug fixes, and improvements. The NTP daemon is used in almost every device that needs to synchronize time on computer clocks. NTP got the most attention in late 2014 and 2015 when hackers used it to launch highly amplified DDoS attacks against services. The flaw which affects NTP.org's nptd versions prior to 4.2.8p9, but not including ntp-4.3.94, has been discovered by security researcher Magnus Stubman, who privately disclosed it to the Network Time Foundation on June 24. A patch for the vulnerability was developed and sent to Stubman on 29th September and just two days later, the researcher acknowledged t

OSquery , an open-source framework created by Facebook that allows organizations to look for potential malware or malicious activity on their networks, was available for Mac OS X and Linux environments until today. But now the social network has announced that the company has developed a Windows version of its osquery tool , too. When Facebook engineers want to monitor thousands of Apple Mac laptops across their organization, they use their own untraditional security tool called OSquery. OSquery is a smart piece of cross-platform software that scans every single computer on an infrastructure and catalogs every aspect of it. Then SQL-based queries allow developers and security teams to monitor low-level functions in real-time and quickly search for malicious behavior and vulnerable applications on their infrastructure. In simple words, OSquery allows an organization to treat its infrastructure as a database, turning OS information into a format that can be queried using SQL
