Warning: The latest iPhone can be controlled with just a PDF file - Don't open unknown PDFs: #AI is making the latest iPhones more vulnerable than ever On October 16, 2026, at the Hexacon conference (Paris), Calif (Thai Duong & Bruce Dang) gave a live demo: An untethered jailbreak on the iPhone 18 Pro running iOS 27.0.1: root privileges persist after rebooting. A 1-click attack via a malicious PDF file in Signal and iMessage: simply opening the file allows code execution on the device. This is not an attack via Gmail. Full technical details have not yet been fully disclosed. Why is it dangerous? iMessage/Signal are extremely popular. A PDF file from an acquaintance or a compromised account is enough to pose a risk. Apple's security remains strong, but the gap with real-world attacks is narrowing, especially as AI helps discover vulnerabilities faster. What to do immediately: Update iOS to the latest version. Do not open unknown PDFs (even from acquaintances) directly on your phone. Consider enabling Lockdown Mode if you belong to a high-risk group. Please share this with your loved ones. Being cautious with attachments is more critical now than ever. Read more: https://blog.calif.io/p/iphone #HackerAlert

The internet is in code red! 🚨 A historic flaw called PHP2Shell has just knocked out the defenses of 7 out of every 10 websites on the planet, forcing banks, airlines, and governments to shut down their emergency systems. Here’s the super-quick rundown of what’s happening and how to save your digital skin: • The danger: It’s a critical flaw in PHP’s memory handling. It lets attackers sneak into the heart of servers without passwords, and do so at scale. • The lifeline (ACT NOW): • Update the interpreter: Install the official PHP patches today. • Clean house: Remove orphaned scripts and old plugins (pre-2019). • Monitor: Carefully check the logs for unusual PHP-FPM processes. AI helped discover it, but hackers are already attacking at the speed of light. If you manage servers or web projects, tell me: What version of PHP are you currently running, or which control panel (such as cPanel or Plesk) do you use? I can give you the exact commands to secure your system right away. #HackerAlert

Unlike hot wallets (which are on your phone or browser and stay connected at all times). Why do people trust them? Because logic says: if the key is not connected to the internet, no hacker can access it. Big investors put their millions there and sleep peacefully. It was considered the impregnable fortress that could not be breached... until August 1, 2026.

A cold wallet is a physical device, similar to a flash drive. Its only job is to keep your private keys away from the internet. Unlike hot wallets (which are on your phone or browser and stay connected at all times).

What really happened with #coldcard It wasn’t an “AI hack”—it was a 2021 firmware bug. The vulnerability was introduced in Coldcard firmware 4.0.0 in March 2021: devices bypassed their hardware random number generator and fell into key generation via software, predictable, seeded with non-secret chip data.  The specific error is in libngu: the guard uses #ifndef MICROPY_HW_ENABLE_RNG, which only checks whether the macro exists, not whether its value is different from zero.  Result: anyone can reproduce the seed candidates offline and derive addresses to compare them with the blockchain—without touching the device. The figure keeps growing in waves: from an initial 594 BTC to 1.082 BTC (1,196 addresses) on July 31, then 1.158 BTC, and on August 2 a third wave brought the total to ~1.367 BTC (~$89M) from 4,585 addresses;  today people talk about a fourth wave. Coinkite released an emergency firmware on July 31 for all affected models, but installing it doesn’t fix an already-existing seed.  You must generate a new seed and move the funds. #HackerAlert #bitcoin $BTC
