New VoidProxy phishing service targets Microsoft 365, Google accounts

A newly discovered phishing-as-a-service (PhaaS) platform, named VoidProxy, targets Microsoft 365 and Google accounts, including those protected by third-party single sign-on (SSO) providers such as Okta. The platform uses adversary-in-the-middle (AitM) tactics to steal credentials, multi-factor authentication (MFA) codes, and session cookies in real time. VoidProxy was discovered by Okta Threat Intelligence researchers, who describe it as scalable, evasive, and sophisticated. The attack begi

DSLRoot, Proxies, and the Threat of ‘Legal Botnets’

The cybersecurity community on Reddit responded in disbelief this month when a self-described Air National Guard member with top secret security clearance began questioning the arrangement they’d made with company called DSLRoot, which was paying $250 a month to plug a pair of laptops into the Redditor’s high-speed Internet connection in the United States. This post examines the history and provenance of DSLRoot, one of the oldest “residential proxy” networks with origins in Russia and Eastern E

Reverse Proxy Deep Dive: Why Load Balancing at Scale Is Hard

This post is part of a series. Part 1 - A deep dive into connection management challenges. Part 2 - The nuances of HTTP parsing and why it’s harder than it looks. Part 3 - The intricacies of service discovery. Part 4 - Why Load Balancing at Scale is Hard. Load Balancing One of the most critical roles for a reverse proxy is load balancing requests across different upstream hosts. From a list of upstream servers, the proxy must decide where each incoming request should go. The primary goals

Making Libcurl Work in WebAssembly

29 Jul, 2025 TLDR: we explain how to make libcurl based applications work in webassembly without changes by tunneling all traffic over a websocket proxy. For a quick demo, check out https://github.com/r-wasm/ws-proxy Porting R to WebAssembly Webr is a port of the R language and its package ecosystem to WebAssembly. Many R packages rely on well-known C/C++ libraries to do the heavy lifting, and fortunately most of these libraries can be built with emscripten without too much trouble. However

Reverse engineering GitHub Actions cache to make it fast

Before this work began, we already had a faster alternative to Github Actions cache. Our approach was different: we forked each of the popular first-party actions that depended on Actions cache to point to our faster, colocated cache. But my coworkers weren’t satisfied with that solution, since it required users to change a single line of code. Apart from the user experience, maintaining these forks steadily turned into a nightmare for us. We kept at it for a while, but eventually reached an in

Reverse Proxy Deep Dive: Why HTTP Parsing at the Edge Is Harder Than It Looks

In Part 1 of this series, we explored a high-level overview of reverse proxies and dived deep into connection management. This post shifts our focus to the intricate world of HTTP handling within a reverse proxy. Deep Dive into HTTP Handling At a high level, the HTTP workflow from a proxy’s perspective might seem straightforward: Receive the request from the client Parse and sanitize the request Uses different requst metadata (path, headers, cookies) to select an upstream host Manipulates the

Show HN: Intercepting proxy for semantic search over visited pages

A proxy that embeds every web page you visit and lets you run similarity searches. Each successful HTTP GET 200 response (except for localhost) is re-fetched from pure.md to obtain clean Markdown. The cleaned text is embedded through llm. A minimal Flask UI provides search and cached-page views. Installation This is not a stand-alone program. It is a plugin for llm. If you are not using llm yet, install it with pipx first. pipx install llm Now you can install this plugin: llm install git+h

Paid proxy servers vs free proxies: Is paying for a proxy service worth it?

marian / Getty Images Proxy servers are the middlemen of cyberspace. Acting as gateways between our devices and the Internet, proxy servers are used by businesses and individuals worldwide for a variety of tasks. While proxy servers were once almost exclusively used by companies to redistribute traffic and load or for caching purposes, they now offer a degree of online anonymity for individuals. Requests you make are first sent to the proxy and then forwarded -- and this process assigns you a
