g.co, Google's official URL shortcut (update: or Google Workspace's domain verification, see bottom), is compromised. People are actively having their Google accounts stolen.

Someone just tried the most sophisticated phishing attack I've ever seen. I almost fell for it. My mind is a little blown.

1. Someone named "Chloe" called me from 650-203-0000 with Caller ID saying "Google". She sounded like a real engineer, the connection was super clear, and she had an American accent. Screenshot.

2. They said that they were from Google Workspace and someone had recently gained access to my account, which they had blocked. They asked me if I had recently logged in from Frankfurt, Germany and I said no.

3. I asked if they can confirm this is Google calling by emailing me from a Google email and they said sure and sent me this email and told me to look for a case number in it, which I saw in

hi, i'm daniel. i'm a 15-year-old high school junior. in my free time, i hack billion dollar companies and build cool stuff.

3 months ago, I discovered a unique 0-click deanonymization attack that allows an attacker to grab the location of any target within a 250 mile radius. With a vulnerable app installed on a target's phone (or as a background application on their laptop), an attacker can send a malicious payload and deanonymize you within seconds--and you wouldn't even know.

I'm publishing this writeup and research as a warning, especially for journalists, activists, and hackers, about this type of undetectable attack. Hundreds of applications are vulnerable, including some of the most popular apps in the world: Signal, Discord, Twitter/X, and others. Here's how it works:

Cloudflare

By the numbers, Cloudflare is easily the most popular CDN on the market. It beats out competitors such as Sucuri, Amazon CloudFront, Akamai, and Fastly. In 2019, a major Cloudflare outage k

step 1: jailbreak your Kindle

mobileread.com is your best resource here, follow the instructions from the LanguageBreak thread

I didn't really follow the LanguageBreak instructions because I didn't care about most of the features + I was curious to do it myself, but the LanguageBreak github repo was invaluable for debugging

/// This is a temporary fix for a bug in coverage reports where awaits show as not covered.
///
/// The idea is that once the bug is fixed, you can easily remove all `.fix_cov()` calls and imports, 
/// delete the `fix_coverage.rs` and eveything works as it previouslt did.
///
/// To use it just simply import the `FixCov` trait and add `.fix_cov` to any future, before the `.await`.
///
/// # Example
/// ```
