I love @duolingo, but the app now is so sloppy I can get back lost 20+ days streak and get 120+ days back instantly. Anyone (without hacking) can bypass instantly audio tasks and farm XP, cheese leaderboards, and get free premium (without special offer).

@yl3ame @SwedbankLatvia NFC apmaksa izdevās ar pirmo piegājienu. Transakcijas (aplikācijā) par pirmo maksājumu nav - čeks ir. Ar otro piegājienu (citā veikalā) neizdevās. 5min laikā redzēju aplikācijā kā pazūd un atkal attēlojas visi konti. Bankomāti ļāva (NFC) autorizāciju, bet neļāva izņemt naudu. 🤷🏻‍♂️

‼️🚨 BREAKING: An AI found a Linux kernel zero-day that roots every distribution since 2017. The exploit fits in 732 bytes of Python. Patch your kernel ASAP.

The vulnerability is CVE-2026-31431, nicknamed "Copy Fail," disclosed today by Theori. It has been sitting quietly in the Linux kernel for nine years.

Most Linux privilege-escalation bugs are picky. They need a precise timing window (a "race"), or specific kernel addresses leaked from somewhere, or careful tuning per distribution. Copy Fail needs none of that. It is a straight-line logic mistake that works on the first try, every time, on every mainstream Linux box.

The attacker just needs a normal user account on the machine. From there, the script asks the kernel to do some encryption work, abuses how that work is wired up, and ends up writing 4 bytes into a memory area called the "page cache" (Linux's high-speed copy of files in RAM). Those 4 bytes can be aimed at any program the system trusts, like /usr/bin/su, the shortcut to becoming root.

Result: the next time anyone runs that program, it lets the attacker in as root.

What should worry most: the corruption never touches the file on disk. It only exists in Linux's in-memory copy of that file. If you imaged the hard drive afterwards, the on-disk file would match the official package hash exactly. Reboot the machine, or just put it under memory pressure (any normal system load that needs the RAM), and the cached copy reloads fresh from disk.

Containers do not help either. The page cache is shared across the whole host, so a process inside a container can use this bug to compromise the underlying server and reach into other tenants.

The original sin was a 2017 "in-place optimization" in a kernel crypto module called algif_aead. It was meant to make encryption slightly faster. The change broke a critical safety assumption, and nobody noticed for nine years. That bug then rode every kernel update from 2017 to today.

This vulnerability affects the following:
🔴 Shared servers (dev boxes, jump hosts, build servers): any user becomes root
🔴 Kubernetes and container clusters: one compromised pod escapes to the host
🔴 CI runners (GitHub Actions, GitLab, Jenkins): a malicious pull request becomes root on the runner
🔴 Cloud platforms running user code (notebooks, agent sandboxes, serverless functions): a tenant becomes host root

Timeline:
🔴 March 23, 2026: reported to the Linux kernel security team
🔴 April 1: patch committed to mainline (commit a664bf3d603d)
🔴 April 22: CVE assigned
🔴 April 29: public disclosure

Mitigation: update your kernel to a build that includes mainline commit a664bf3d603d. If you cannot patch immediately, turn off the vulnerable module:

echo "install algif_aead /bin/false" > /etc/modprobe.d/disable-algif.conf
rmmod algif_aead 2>/dev/null || true

For environments that run untrusted code (containers, sandboxes, CI runners), block access to the kernel's AF_ALG crypto interface entirely, even after patching. Almost nothing legitimate needs it, and blocking it shuts the door on this whole class of bug...

You’re being identified even without cookies:

Incognito Mode doesn't make you invisible. Neither does your VPN.
Websites don't need Cookies to track you. One method is Canvas fingerprinting

How it works:
The website secretly asks your browser to draw a hidden image (text + emojis + 3D shapes) using the HTML5 Canvas API.

Because every computer has a slightly different combination of Graphics Card, Drivers, Fonts, and OS, your browser renders that image slightly differently than everyone else's.

The Result:
They turn those tiny rendering differences into a Unique Hash.

They aren't tracking your IP. They are tracking your Hardware.

You can delete your cookies. You can't delete your GPU.

i've been hacked

and traced the malware's wallet to see how much money they actually made from this new exploit

(if you use Next.js/React, READ THIS!)

I woke up to a terrifying email from Hetzner: "Netscan Detected."

my server was blocked and a botnet was using my IP to attack others

i dug into the logs and what I found the anatomy of the attack:

1) The Symptoms: I logged into htop and saw the mess:

- CPU usage: 361%
- A process named ./3ZU1yLK4 running wild
- Random connections to an IP in the Netherlands

my server wasn't serving my app anymore; it was mining crypto for someone else!

2) The Culprit: It wasn't a random SSH brute force. It was inside my Next.js container

the malware was sophisticated

it renamed itself nginxs and apaches to look like web servers

it even had a "killer" script that hunted down other hackers' miners to kill the competition

3) The "Root" Cause (literally): Probably the recent React/Next.js CVE-2025-66478 exploit was the entry point

(my project was running on "next": "15.5.4", behind cloudflare dns, but their recent fix didn't work apparently)

but the fatal error was mine: my Docker container was running as ROOT

Coolify deploys like this automatically when using Nixpacks, and I never changed it...

so because of USER root, the malware could install cron, systemd, and persistence scripts to survive reboots

meaning, it was able to infect my whole server, from a single Next.js docker!

4) The Forensics: I ran docker diff on the container - the hacker didn't just run a script, they installed a whole toolset..

- /tmp/apaches.sh (The installer)
- /var/spool/cron/root (The persistence)
- /c.json (The wallet config)

5) The Fix: I killed the container, scrubbed the host, and extracted the malware for analysis.

but the real fix is in the Dockerfile. if you are deploying Node/Next.js, DO NOT use the default (root), you must:

- RUN adduser --system nextjs
- USER nextjs

if you have Docker on ROOT and didn't update the exploited react version, you'll be hacked soon

check your containers NOW. Run: docker exec <container_id> id

(or get the full list first: docker stats --no-stream)

If it says uid=0(root), you are one vulnerability away from being a crypto-miner host.

(it's easy to notice when hacked, it will be a command running on the top CPU%, using all your hardware resources)

6) The Money: I dug deeper and recovered the config file (c.json)

- Wallet: A Monero (XMR) address: 831abXJn8dBdVe5nZ***
- Pool: auto.c3pool . org

and ofc i tracked the hacker’s wallet on the mining pool

7) The Scale: My server wasn't alone. It was just 1 of 415 active zombies in this botnet

they are burning the CPU of 400+ cloud servers... to earn...

guess how many millions?

$4.26/day

on the image attached you can see: "Total Paid: 0.00", meaning this campaign just started. I caught them on Day 1.

i also tracked back the server where they hosted the malware, and by inspecting the code, I found several comments in Chinese, so I guess that's their origin

im rebuilding from scratch on a fresh VPS. the lesson was expensive, but at least I caught it before the hosting nuked my account permanently...

PS: I have the IP for all the other machines mining with that malware, not sure how I can help them, but feel free to contact me if ur doing infosec

stay safe
