Anyone running @GrapheneOS, Android Auto?

Its no longer working for me in my Audi.

Stopped a while ago, since a recent update I'm assuming.

Sometimes doing things right, and the right thing... isn't enough.

Today I was made painfully aware of this fact.

I've never quite before seen so many bugbounty hackers / cybersecurity professionals excited about AI. Not because of AI per se, but because it will generate so much new income.

We have almost quite literally taken everything we've learnt, thrown it out the window, and reintroduced injection […]

Alright. Arc Raiders is awesome and it works flawlessly on Fedora 43.

You know what... Vagrant. I have heard about this for I don't know many years, but never actually understood what it is.

Today I finally learned it. I feel... stupid for not knowing. It's amazing! 🙂

Microsoft has published research about predicting and classifying topics discussed with Ai-bots with 100% precision WITH encryption.

I must say this was pretty cool research […]

I've realized that I get ... disoriented (?) when reading toot threads. Each toot starting with the replied to username is not really useful.

I think when a Posted toot is rendered replied to usernames could simply by pushed to the bottom of the toot, or somehow hidden away.

Anyone else got […]

We’ve launched At The Edge, a weekly brief for GreyNoise customers highlighting shifts in attacker behavior seen across the Global Observation Grid (GOG).

Human-led analysis that turns internet noise into insight defenders can act on.

According to Akido.dev there's an ongoing attack (again) on Open VSX.

The attack leverages non-printable Unicode characters to conceal malicious payloads within legitimate Open VSX extensions, making detection challenging through visual inspection […]

Huntress has published an article about Gootloader with an absolutely ridiculous amount of IoCs to hunt for, beyond an already excellent technical deep dive.

Raising the bar?

Gootloader returns with new obfuscation techniques, including custom WOFF2 fonts and updated persistence mechanisms, while continuing its partnership with Vanilla Tempest for ransomware deployment. Dive in and discover what Huntress is seeing.

PHP Cryptomining Campaign: October/November 2025
From Aug–Oct 2025, GreyNoise observed a surge in exploitation attempts against PHP and PHP-based frameworks as attackers deployed cryptominers—driven by rising Bitcoin prices and higher mining payoffs.

Quick question to the blue teamers out there:

What's your take on MITRE ATT&CK Tactics and Techniques? Do you find them useful? If yes, how and in what capacity do you use them? (To the extent that you can and want to share...)

If you could have tactics and techniques extracted from publicly […]

Let's pretend 80% of ransomware is enabled by AI, let's. Oh... cyber bloodhound Beaumont has sniffed us out and discovered our claim... fuck fuck... retract, backup...

Too late. There are screenshots. You failed.

As we're getting closer to enabling "multiplayer" mode in our sensor fleet, we added some eye candy.

This is "all of GreyNoise production", but folks who will be hosting their own sensors (we call them "GridPoints" internally) will get a tailored view of their deployments as well.

This is a great article about depending on AI for doing... your job.

I've tried to maintain a balance, because I too do fear becoming dependent on something I don't control.

I don't believe in all out rejection, but at the same time we need to encourage responsible development of open source […]

Steganography is used pretty extensively in malware and attacks these days. But I have yet to see my own method used.

About 3 years ago I coded my own version of a PNG steganographic implementation injecting a custom PNG chunk into the regular PNG chain of chunks.

It was a simple yet effective […]
