State Secrets for Sale: Inside China's Hack-for-Hire Ecosystem In the shadowy world of global cyber espionage, secrets are currency and recently, some of China’s most sensitive digital assets hit the open market. Two recent leaks, dubbed the VenusTech and Salt Typhoon dumps, have peeled back the curtain on a structured, state-affiliated hacking ecosystem operating within China. Posted to DarkForums, the successor to BreachForums, these leaks expose a rare look into the inner workings of the Chinese cyber industrial complex. The VenusTech Leak: Government-Backed Espionage-as-a-Service VenusTech, a Chinese cybersecurity firm with ties to government entities, had its internal documents leaked, revealing a chilling level of operational maturity. Among the documents: Spreadsheets of targeted countries and agencies, including intelligence objectives in Taiwan, South Korea, India, Croatia, and Thailand. Delivery schedules for stolen data for example, recurring...

CUDA (Compute Unified Device Architecture) Can your GPU utilize CUDA?? CUDA (Compute Unified Device Architecture)  is a  parallel computing platform and programming model  developed by  NVIDIA  that allows software developers to use  NVIDIA GPUs  to perform general-purpose computing tasks much faster than using a CPU alone. You need CUDA when you want to: ✅ Accelerate compute-heavy tasks CUDA lets you use the massive parallel processing power of NVIDIA GPUs to speed up operations like: Machine learning and AI training Scientific simulations Image and video processing Cryptography Data analytics 3D rendering ✅ Unlock GPU computing capabilities Without CUDA, your code typically runs only on the CPU. CUDA enables you to offload tasks to the GPU, which can run thousands of operations in parallel , making it ideal for high-performance computing. ✅ Develop GPU-accelerated applications CUDA provides a C/C++ API and other tools to write co...

RDMA (Remote Direct Memory Access) is a high-performance networking technology that allows direct memory access between computers over a network without involving the CPU, cache, or operating system of either the sender or the receiver. What RDMA Does Traditionally, when data is transferred between systems:     It’s copied from user space to kernel space.     Passed through the network stack.     Received in the kernel and copied again to user space. With RDMA, data can be read/written directly from the memory of one machine to another, bypassing the kernel and reducing CPU usage and latency. How RDMA Works     No CPU interrupts on the receiving side.     No context switches or system calls during data transfer.     Uses zero-copy principles.     Memory regions are pre-registered with the NIC.     The NIC (RDMA-capable) directly reads/writes from/to memory. RDMA Protocols     InfiniBand   ...

Maximize the performance of your NVIDIA GeForce RTX 5070 on Windows 11, you can optimize both hardware and software settings. Below is a step-by-step guide focusing on driver updates, NVIDIA Control Panel settings, overclocking with MSI Afterburner, and Windows 11 optimizations. Each step includes relevant code or configuration details wrapped in an <xaiArtifact> tag where applicable. ***Note that some steps involve configuration rather than code, but I’ll provide scripts where possible to automate or illustrate the process. Step 1: Update NVIDIA Drivers to the Latest Version Keeping your GPU drivers up to date ensures optimal performance and compatibility with games and applications, especially for the RTX 5070, which requires the latest Game Ready Drivers for DLSS 4 and Multi Frame Generation support. Action: Download and install the latest NVIDIA Game Ready Driver from the NVIDIA website or use the NVIDIA App. Why: The latest drivers (e.g., 572.47 WHQL) include o...

  Between Ceasefire and Cyberwar: The Invisible Front of Iranian Threats In late June 2025, U.S. cybersecurity agencies CISA, FBI, NSA, and DC3 issued a striking joint bulletin: Iranian state‑linked and affiliated hacktivist groups may soon turn their sights on U.S. critical infrastructure, including utilities, transportation networks, and defense contractors, particularly those with Israeli ties. On the surface, a ceasefire between Iran and Israel would suggest a pause in cyber hostilities but the digital battleground never sleeps. Iranian proxies, operating with plausible deniability, could launch campaigns: DDoS assaults, ransomware activity, wiper malware attacks, defacements, and even theft and leakage of sensitive information. Why This Threat Matters Critical Infrastructure Is an Achilles' Heel OT (operational technology) systems managing power plants, water utilities, and industrial sensors are traditionally less secure than IT networks. They...
