An exploit chain was found in LG webOS, leading to root command execution. The chain starts with a client-key issuance bypass, progresses through service-level access, and ultimately leads to root command execution.

TL;DR: NVIDIA DCGM Exporter is a widely used monitoring tool that collects GPU metrics like utilization, memory, temperature, and power consumption from AI servers.
We discovered that thousands of these monitoring endpoints are exposed to the public internet, allowing anyone to inspect GPU infrastructure. Worse, we found a high-severity vulnerability (CVE-2026-47483, CVSS 8.2) that lets unauthenticated attackers exhaust server resources, crash GPU monitoring, and potentially disrupt AI workloads remotely.
A few other interesting findings:
2,100+ exposed GPU servers, revealing telemetry from 12,000+ GPUs worth ~$100M, including H100s, H200s, and Blackwell GPUs.
60% of exposed GPUs reported 0% utilization across our scans.
12,096 additional servers exposed infrastructure details, including OS, firmware, and networking information.
NVIDIA fixed the vulnerability following our responsible disclosure.

It turns out you can overwrite the Error.prepareStackTrace method with the function constructor. Then, using prototype pollution, you can inject valid JavaScript code to generate arbitrary functions and invoke it using the usual tricks.

Four incidents, four completely different initial access paths:

• 2022, Lapsus$: MFA fatigue against an employee, then hardcoded creds and API keys sitting in plaintext in Slack and Confluence.
• Early 2023, GTA Online: P2P netcode on PC reverse-engineered into RCE via malicious packets. The fix was kernel-level BattlEye.
• April 2026, ShinyHunters: no human identity involved. Long-lived OAuth tokens stolen from a third-party SaaS vendor and replayed straight into Rockstar's Snowflake. Bearer tokens confer authority by possession alone.
• August 2026, Cyberleek: exfiltration of a playable GTA VI dev build, 13+ gameplay videos and full map data. That volume of egress from a dev subnet without tripping alarms is a DLP and segmentation failure.

The writeup reconstructs each attack chain with MITRE mappings and detection strategies: egress baselining on dev subnets, Slack audit-log heuristics, and behavioral baselines for non-human identities in Snowflake.

Question for the defenders here: which of these four would be hardest to catch in your environment? The OAuth token replay is arguably the nastiest of the bunch. No user to phish-train, no endpoint alert to fire.

I wanted to share a project I’ve been working on that I’m super excited about:

Project RedTeam: Contract Offensive

There’s a free Demo that provides a tutorial and lets you play a few contracts (no time limit, play as much as you want). Some players are already pulling some serious hours in the demo!

At its core, this is a game about using MITRE ATT&CK adversarial techniques against procedurally generated networks. It's delivered in a gameplay loop that plays a lot like Balatro and other card based Roguelike games. In Project RedTeam, you need to earn money to pay off debts after every contract within a run. Earn money by completing objectives, side bounties, or executing exfiltration/ransom against targets- the choice on how to be profitable is always yours.

It's a challenging but fun and fast paced take on network-intrusion cybersecurity concepts. It's entertaining in a deliberately gamified way.

A goal of this project was to create a hacking game that is realistic enough to keep it meaningful as a tool to teach intrusion concepts and stages to anyone- but not be overcomplicated and slow-paced like most hacking games.

I've put a lot of thought into the design and dynamics of how to capture the core-loop of network intrusion and turn it into a game that's approachable. The design direction of this project is an outcome of having over a decade of training and experience in cybersecurity.

Feel free to AMA! I'm happy to answer any questions about the game and/or development process :)

Give the game a Wishlist on Steam or share this post if it's something you support and want to see further development on.

Project background: This was implemented over the past 3 months using a modern development workflow (yes, modern AI tools make this possible- I'm not hiding that fact!). That being said, this is by far the most complex software project I've built as a solo developer and it was not an easy or simple development task. There's a Steam Community with a Dev Blog for this game that provides more history/progress updates on the project.

Mods: This will be my only and last post here, since it is promotional. I just wanted to share this since there’s been very positive interest from similar subreddits.

I was going through the SelectorsHub code, id:ndgimibanhlabgdgjcpbbndiehljcpfh the XPath extension with about 400k users, and noticed it pulls ads from its own server and opens them in a background tab. You don't click anything.

Every couple of days the side panel pops up a "community link" and says "100% Safe, No Spam, No Malware." Five seconds later the tab opens by itself. The URL isn't in the extension. Their server picks it, and while I was analysing the extension the links changed three times with no extension update.

On install and update it skips the popup and just opens whatever the server sends.

The store page says they collect no data. The code still pings them daily, and the extension reads all your cookies to find one of its own instead of just fetching its own cookie value.

Another weird finding: there's a hidden Fix Selector button that sends the selector to shubads[.]testcasehub.net. VirusTotal - Domain - shubads.testcasehub.net
That host now redirects to a gambling site, blomehairdryers[.]com.

Nothing gets run today because the reply is HTML, but that's the server the eval path trusts.

Looks like adware, not password theft. I wouldn't leave it on a work browser, especially since this is a tool used by devs and tech people browsing protected endpoints in a company.
