A botnet consists of numerous “zombie” computers and can be used, for instance, to carry out DDoS attacks. Here’s what you should know about the topic. FOTOKINA | shutterstock.com Cybercriminals are constantly looking for ways to spread malware on a large scale or launch Distributed Denial of Service (DDoS) attacks. A botnet is particularly well-suited for this purpose. Botnet – Definition A botnet is a collection of internet-connected devices that have been compromised by an attacker to carry out DDoS attacks and other tasks as a coordinated “swarm.” The core idea is simple: every computer that joins the botnet becomes…

Sabrina Ortiz/ZDNETStay updated with ZDNET: Add us as a preferred source on Google.While the Android smartphone space may not be as fiercely competitive as it once was, buyers still enjoy a wide variety of choices. Options range from traditional slab-style phones and book-style foldables to flip phones and even devices with physical keyboards. Although iPhones hold a commanding 69% market share in the U.S., Android continues to offer greater feature depth and more flexibility in hardware design.Related: Why I suggest this $450 Samsung phone over similar models from Google and OnePlusWhen shopping for a new Android device, your decision often…

On June 4, 1996, Ariane 5 completed its maiden flight — a new European heavy-lift rocket engineered to place payloads into low Earth orbit. The vehicle blew up less than 40 seconds after launch. The root cause was specification and design flaws embedded in the software of the inertial reference system. A piece of software had been carried over from the earlier Ariane 4 without confirming that its assumptions still held in the updated environment. The failure went on to rank among the most costly software bugs ever recorded. Why bring up an incident from three decades ago in a…

Over the past couple of months, improvements to long-standing IT automation platforms will start linking agentic AI directly to core enterprise systems — including ERP platforms and mainframes. For years, businesses have relied on workload automation and orchestration tools, which originated long before cloud computing and DevOps became mainstream. These tools have since been updated to support newer trends and, more recently, have been enhanced to work with generative AI and agentic AI. Platforms in this space automate routine tasks and integrate varied, complex software systems into unified business processes with strong dependability, according to Dan Twing, an analyst at…

Extensive field tests carried out throughout Japan have delivered one of the most thorough real-world assessments yet of Wi-Fi HaLow — a long-range, energy-efficient version of Wi-Fi purpose-built for Internet of Things (IoT) applications. The trials were organised by the Wireless Broadband Alliance alongside industry partners, and examined performance across four distinctly different settings: a public park, an urban school campus, a multi-storey residential building, and a water treatment facility. At each site, engineers typically used a single access point to evaluate performance, tracking connectivity range, signal strength (RSSI), data throughput, latency, and packet loss as devices were positioned at…

In brief Nous Research’s Hermes Agent crossed 100,000 GitHub stars in 10 weeks, spawning a fast-growing ecosystem of community-built GUI wrappers. Four community interfaces now let users skip the command line entirely, from a Mac-native SSH companion to a full mobile PWA accessible via Tailscale. All four GUIs run on a standard Hermes install and none require patching or forking the agent itself. So you installed Hermes. You ran it, asked it some things, it remembered them, maybe even built a skill on its own. Pretty good.But now you’re staring at a terminal window and wondering if this is really…

I’ve been tackling the consumer multi-GPU PCIe bandwidth problem — Nvidia dropped NVLink from the 4090/5090, so distributing a 70B model across two consumer GPUs limits you to roughly 30 GB/s over PCIe peer-to-peer. Over the past few months, I’ve built a Python library that leverages the GPU’s otherwise-unused NVENC/NVDEC hardware to compress activations and KV cache in real time, then transmits the compact bitstream across the same connection. Repository: (Apache 2.0) Existing work (the concept itself isn’t new) LLM.265 — “Video Codecs are Secretly Tensor Codecs” (late 2025). The most closely related prior work: same core insight applied to…

A joint international crackdown by American and Chinese authorities has resulted in the detention of at least 276 individuals and the closure of nine fraud hubs involved in cryptocurrency investment scams aimed at U.S. citizens, which caused losses running into millions of dollars. The operation was spearheaded by the Dubai Police, under the umbrella of the United Arab Emirates (UAE) Ministry of Interior, working alongside the U.S. Federal Bureau of Investigation (FBI) and the Chinese Ministry of Public Security. Among those taken into custody are nationals from Burma and Indonesia, who were detained by authorities in Dubai and Thailand. Thet…

Eric White In a way, the title really does say it all—providing various event tickets to veterans to offer them a bit of recreation and fulfill that desire many of us share to get out and about. Could we take a small step back? I’d like to learn more about the organization’s story and how it all started. Steve Weintraub Absolutely. It was founded locally in 2008 in Tempe, Arizona, which is near Phoenix. Our founder, Mike Focareto, a Navy veteran, came up with the whole idea. Our core mission is to give something to those who gave. Back in…
