Rust Tool 'multiprobe' Pinpoints Firewall Hops by Running Multi-Protocol Traceroutes at Once

0
·2 views

A developer has added a protocol divergence detection feature to multiprobe, an open-source Rust networking library. The tool runs ICMP, TCP, and UDP traceroutes simultaneously and compares responses at each network hop to identify where traffic is being selectively blocked. When protocols start behaving differently at a given hop, multiprobe flags that router or firewall as the likely culprit and assigns an agreement score to quantify the divergence. The feature is aimed at network engineers troubleshooting firewall rules, middlebox interference, or ISP-level traffic filtering. Multiprobe is available as both a CLI tool and a Rust library via crates.io, though it requires elevated privileges to use raw sockets on Linux and macOS.

ECC: Open-Source OS Framework Brings Structured Workflows to AI Coding Agents

Developer affaan-m has released ECC (Everything Claude Code), an open-source performance harness designed to give AI coding assistants like Claude Code and Codex a structured engineering environment. Rather than relying on single-turn prompting, ECC enforces a defined lifecycle — plan, test, implement, review, verify, and improve — directly within the terminal agent's runtime. The framework bundles pre-configured roles for architecture planning, test-driven development, self-review, and domain-specific tooling covering frontend, backend, and DevOps tasks. A built-in security module called AgentShield audits prompt inputs, MCP configurations, and credentials to guard against vulnerabilities as agents gain broader system access. ECC also manages context window efficiency by retaining key architectural lessons and project conventions across sessions, and can be installed via a guided setup using npx or Claude Code's plugin manager.

Model Context Protocol Offers a Unified Standard for Connecting AI to Domain Systems

The Model Context Protocol (MCP), introduced by Anthropic in November 2024, is an open standard designed to give large language models controlled access to external data sources and tools. Before MCP, every AI application required its own custom integration with domain systems, creating a fragmented tangle of duplicate tool descriptions, varied authentication methods, and hard-to-reuse security logic. MCP addresses this by defining a shared host-client-server architecture using JSON-RPC 2.0, enabling AI hosts such as chat clients, IDEs, and agent tools to connect to domain systems through a single protocol. A developer documenting their own MCP server build — built atop a custom ticket system — illustrates how the standard allows an AI to query current, permission-scoped data rather than relying on guesswork or copied context. The article, first in a series, focuses on foundational concepts, with a follow-up planned to cover interface design and security considerations for a responsible MCP server implementation.

PicoCTF Mod 26 Challenge Solved by Brute-Forcing All 26 Caesar Cipher Shifts

A beginner-level cryptography challenge on the picoGym platform tasked participants with decrypting a ciphertext secured using a Caesar cipher. The hint embedded in the challenge explicitly referenced adding 26 to each letter modulo the alphabet size, pointing directly to a Caesar cipher approach. Since the Caesar cipher has only 26 possible shift values, a short Python script could test every combination in under a second. Scanning all 26 outputs for the known flag prefix 'picoCTF{' immediately identified shift 4 as the correct key. The exercise highlights a fundamental weakness of classical ciphers: an extremely small key space makes brute-force attacks trivially fast and effective.

Kenyan Developer Builds Happening App to Centralize Local Event Discovery

An independent developer based in Kenya is building Happening, a social app designed to help users discover events, communities, and experiences in their area. The app aims to replace the fragmented practice of finding event information across Instagram, WhatsApp, websites, and posters by consolidating discovery and social interaction in one place. Planned features include event listings, ticketing, community groups, discussion threads, photo sharing, private invitations, and verified organizers. The founder describes the project as currently in early stages and is actively seeking feedback from developers, designers, event organizers, and potential users. The app is accessible at happening.co.ke as the developer looks to grow an initial user base.
