Attackers move the ClickFix paste into Windows Terminal to land a multi-stage intrusion chain

Microsoft's TerminalFix writeup shows the same fake CAPTCHA lure now feeding multi-line PowerShell into Windows Terminal, where it sideloads a signed binary, pulls payloads out of PNG files and leaves a reverse tunnel behind.

Cloudflare's Turnstile Spin has coding agents wire Siteverify into the backend

Cloudflare's Turnstile Spin lets a coding agent install both halves of Turnstile, a service handling about three billion verifications on a typical weekday. The backend Siteverify call is the part of the agent's diff to review, since a widget alone issues tokens nobody checks.

A $300 solver bill leaves CAPTCHA at 5% of a credential run's cost of goods

The 5% comes from one dev.to post's worked example, and it holds only if an attacker's hit rate against your login is near 0.3% and a stolen account resells near $20. At a 0.03% hit rate the same bill is half of revenue.

An edge rule of 3 requests per 10 seconds still admits 1,080 login attempts an hour

SyllogOS layers a Cloudflare Free rate limit, Turnstile and an in-app limiter in front of one login form. The author's own published thresholds show which of the three actually caps a patient attacker.

A dev-server alias kept a cron handler out of the deployed Cloudflare Worker

A week building an image SaaS on Cloudflare Workers produced nine failures. In the five shown in code, two come from the TanStack Start plugin's build behaviour and three from React timing and captcha logic that follow the code anywhere.

DFIR Report puts eleven years of Bing SEO poisoning on two Rajasthan IT firms

MayaBot only shows up in 2022, seven years into the operation, and one branch of the funnel ends in a phone call to a scam call centre. That leaves the search referral and the redirector domains as the constants worth detecting.

TerminalFix delivers its first stage through the clipboard of the person it targets

The chain Microsoft describes starts with a fake Cloudflare check on a compromised page and ends in a WebSocket tunnel into the LAN. Every gate that stops it sits on the endpoint or the egress path.
