Network Doctor Tool Adds SSH-Based Remote Diagnosis to Pinpoint Network Faults

0
·1 views

A developer has extended the Network Doctor command-line tool with a --via flag that runs network diagnostics from a remote machine over SSH, rather than only from the local host. The feature lets users compare results across two machines — such as a Linux workstation and a Windows laptop — to isolate whether a connectivity problem is local or upstream. By treating the remote machine as the vantage point, the tool integrates the location of the probe into its dependency-graph diagnostic model. This allows structured checks — covering DNS, TCP, TLS, HTTP, and routing — to be run against named service profiles from the remote host. The approach offers more targeted evidence than simply SSHing into another machine and running commands manually.

Paxos Gold Smart Contract Rated Low On-Chain Risk, Centralization Flagged as Key Threat

A DeFi security research team published a vulnerability analysis of Paxos Gold (PAXG), a tokenized gold asset on Ethereum, on October 26, 2023. The protocol holds approximately $1.91 billion in total value locked and is backed 1:1 by physical gold bullion held by Paxos Trust Company. Analysts assigned an overall risk score of 3.2 out of 10, citing minimal on-chain attack surface due to the contract's straightforward ERC-20 design with no complex financial logic. The greatest identified risk is centralization, as Paxos holds sole authority over minting, burning, and pausing the contract, meaning a compromised owner key could have critical consequences. Secondary risks include off-chain dependencies such as vault security and regulatory compliance, as well as vulnerabilities that may arise when PAXG is used as collateral in third-party DeFi protocols.

Annya Leads Uses AI Agents to Enrich, Score, and Route Sales Leads Automatically

A team built Annya Leads, an agentic lead generation system, as an entry for the AllThingsAgenticHackathon on DEV Community. The platform addresses a common sales problem: inbound leads often arrive with incomplete data and no consistent process for prioritization or follow-up. Annya Leads combines lead enrichment, scoring, and intelligent orchestration into a modular pipeline that automatically fills data gaps, assesses conversion likelihood, and routes each lead to the appropriate team or workflow. The system relies on domain rules, external enrichment signals, and AI-assisted evaluation to improve decision-making quality. Its modular architecture is designed to integrate with existing sales and marketing tools while remaining scalable and operationally traceable.

NIST Finalizes Post-Quantum Standards as 'Harvest Now, Decrypt Later' Threat Looms

Post-quantum cryptography refers to algorithms built to withstand attacks from both classical and quantum computers, addressing a vulnerability in today's widely used encryption methods. Although no quantum computer can currently break modern encryption, adversaries can collect and store encrypted data now to decrypt it once quantum capability matures — a strategy known as 'harvest now, decrypt later'. In 2024, the US standards body NIST finalized its first post-quantum algorithms, ML-KEM for key exchange and ML-DSA for digital signatures, which governments and large organizations are beginning to adopt. Security experts currently recommend a hybrid approach — pairing classical algorithms with post-quantum ones — so that protection holds unless both simultaneously fail. Organizations are advised to audit their cryptographic usage, prioritize long-lived sensitive data, and rely on vetted libraries rather than custom-built solutions.

How to Fix Cloudflare's 'Enable JavaScript and Cookies' Block Error

The 'Enable JavaScript and cookies to continue' message appears when Cloudflare's security layer blocks a request, detecting that the client fails its browser integrity checks. This commonly affects automated HTTP tools like curl, Python requests, or axios, as well as browsers with JavaScript or cookies disabled. To resolve it in a standard browser, users should enable JavaScript and cookies in settings and temporarily disable privacy extensions such as uBlock Origin or Ghostery. Developers using HTTP clients can bypass the challenge by using libraries like cloudscraper, which simulates a real browser and handles dynamic cookies automatically. Those with access to Cloudflare's backend can also temporarily lower the security challenge level in development environments, though disabling protections in production is strongly discouraged.
