"Its sole function is to convert a single compromised machine into a controllable relay point, an access amplifier, through which an operator can pivot to internal systems, services, and network segments that would otherwise be unreachable from outside the perimeter."
All smart homes are at risk of being hacked, but it's not a likely event. The type of bad actors that target smart homes and devices, such as security cameras, are opportunistic. They search randomly for easy targets -- they don't tend to choose a particular home to attack and then try to circumvent that specific system.
The zero-day in Cisco Catalyst SD-WAN is being actively exploited, according to Cisco's security arm Talos. The research team discovered that attackers are using this vulnerability to compromise controllers and connect malicious peers to target networks. The group UAT-8616, which is not yet known, has been exploiting the flaw since at least 2023.
The partnership aims to future-proof the iconic New York venue's digital footprint. The collaboration focuses on leveraging a flexible, high-performance infrastructure capable of handling the massive data demands of modern live entertainment, from high-density fan Wi-Fi to back-of-house operational systems. Powering a connected experience MSG will leverage a suite of Cisco's enterprise networking and security hardware. This includes the use of Cisco Catalyst Switches to secure and simplify the network foundation, alongside the Cisco Catalyst Center for centralised management.
In today's hospitality landscape, high-quality WiFi is no longer an amenity; it's a utility, as fundamental as hot water or clean linen. For modern travellers, a weak or unreliable internet connection can be the deciding factor between a glowing review and a vow never to return. This guide, aimed at hotel managers and owners, delves into the critical components of selecting the best WiFi solution, exploring how operators likeWifirst are setting new standards for guest connectivity and operational excellence.
A branch environment is completely different from that of an organization's head office. Of course, employees want a fast and, above all, reliable Wi-Fi connection there too. The same applies to the internet connection. In addition, employees also see workloads disappearing to other locations. In addition to SaaS and public cloud, they are also moving to the company's central data center. New AI workloads at the branch, like more automated customer services at retail sites, certainly don't make the branch environment any easier to manage.
The nmap command (short for network mapper) is a network exploration/security auditing tool that can rapidly scan networks to help you find out what hosts are available. With nmap, you can discover open ports and services, and even find out what operating systems are on your network. I've used nmap to find out what machines are on a network and what ports/services are open. If I find a port that shouldn't be open, I can close it to avoid security issues.
DynamicLink offers real-time network configuration. It enables customers to turn up and scale network connectivity services such as DIA, Ethernet, Cloudlink, and IP-VPN at any location. This includes clouds, on-net locations, and type 2 off-net sites. Once connected, all network services are configurable directly through the DynamicLink platform. No on-premise physical equipment is required, which future-proofs the network. Other features of the Zayo DynamicLink Naas include: Self-service management: Manage network configurations, bandwidth allocation, cloud connectivity, and other elements directly through the platform, without manual provisioning or service tickets.
DDoS detection tool FastNetMon detected a DDoS attack of 1.5 billion packets per second. The target: a European provider of DDoS scrubbing services. The attack is one of the largest DDoS attacks ever, but still falls far short of the 11.5 billion packets recently detected by Cloudflare. The choice of target is striking in any case: the DDoS attack was aimed at a service that protects other organizations against the consequences of such a "packet flood."
Davis Lu, 55, was convicted of installing a "kill switch" on the network of his former employer by planting malicious code designed to crash its servers in the event that he was fired. The kill switch was activated when the company terminated Lu's employment and deactivated his credentials, causing the kill switch, "IsDLEnabledinAD" - referring to whether Lu's account was still active in the company's Active Directory. The incident locked out thousands of employees from accessing the company's systems.
The threat actor leveraged combinations of sophisticated and stealthy techniques creating multilayered attack kill chains to facilitate access to restricted and segmented network assets within presumed to be isolated environments.
Microsoft has issued a warning that Windows Server 2025 domain controllers may experience accessibility issues following a restart, causing critical interruptions to services and applications.
