HP lt4132 4G modem linux support (EliteBook G5)

[How-To] HP lt4132 - 4G LTE modem - Linux support

This guide has been tested in Xubuntu 18.04.01 but it will probably apply in most linux distro's. Contents are heavily based on work by @toreanderson here.

So HP Elitebook G5 has as an LTE modem the HP lt4132 which is actually re-brand of Huawei ME906s-158.

If you see the output from usb-devices you'll see that the issue lies that the modem is in configuration 2 (Cfg#= 2). The Linux kernel selects configuration 2 by default, but that does not work with ModemManager. Configuration 3 ( MBIM mode) is a much better choice.

Changing to configuration 3 is easy enough. Note that it is essential to first deconfigure the device by selecting configuration

Arch Linux Full-Disk Encryption Installation Guide [Encrypted Boot, UEFI, NVMe, Evil Maid]

Arch Linux Full-Disk Encryption Installation Guide

This guide provides instructions for an Arch Linux installation featuring full-disk encryption via LVM on LUKS and an encrypted boot partition (GRUB) for UEFI systems.

Following the main installation are further instructions to harden against Evil Maid attacks via UEFI Secure Boot custom key enrollment and self-signed kernel and bootloader.

Preface

You will find most of this information pulled from the Arch Wiki and other resources linked thereof.

Note: The system was installed on an NVMe SSD, substitute /dev/nvme0nX with /dev/sdX or your device as needed.

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
