Attackers are actively exploiting a zero-day bug in Gogs, a popular self-hosted Git service, and the open source project doesn't yet have a fix.…
AI-powered browsers give you much more than a window to the web. They represent an entirely new way to experience the internet, with an AI “agent” working by your side.
We’re entering an age where you can delegate all kinds of tasks to a browser, and with that comes a few things you’ll want to keep in mind when using AI browsers like ChatGPT’s Atlas, Perplexity’s Comet, and others.
So, what’s the allure of this new breed of browser? The answer is that it’s highly helpful, and plenty more.
By design, these “agentic” AI browsers actively assist you with the things you do online. They can automate tasks and interpret your intentions when you make a request. Further, they can work proactively by anticipating things you might need or by offering suggestions.
In a way, an AI browser works like a personal assistant. It can summarize the pages in several open tabs, conduct research on just about any topic you ask it to, or even track down the lowest airfare to Paris in the month of May. Want it to order ink for your printer and some batteries for your remote? It can do that too. And that’s just to name a few possibilities.
As you can see, referring to the AI in these browsers as “agentic” fits. It truly works like an agent on your behalf, a capability that promises to get more powerful over time.
But as with any new technology, early adopters should balance excitement with awareness, especially when it comes to privacy and security. You might have seen some recent headlines that shared word of security concerns with these browsers.
The reported exploits vary, as does the harm they can potentially inflict. That ranges from stealing personal info, gaining access to Gmail and Google Drive files, installing malware, and injecting the AI’s “memory” with malicious instructions, which can follow from session to session and device to device, wherever a user logs in.
Our own research has shown that some of these attacks are now tougher to pull off than they were initially, particularly as the AI browser companies continue to put guardrails in place. If anything, this reinforces a long-standing truth about online security, it’s a cat-and-mouse game. Tech companies put protections in place, bad actors discover an exploit, companies put further protections in place, new exploits crop up, and so on. It’s much the same in the rapidly evolving space of AI browsers. The technology might be new, but the game certainly isn’t.
While these reports don’t mean AI browsers are necessarily unsafe to use, they do underscore how fast this space is evolving…and why caution is smart as the tech matures.
It’s still early days for AI-powered browsers and understanding the security and privacy implications of their use. With that, we strongly recommend the following to help reduce your risk:
Don’t let an AI browser do what you wouldn’t let a stranger do. Handle things like your banking, finances, and health on your own. And the same certainly goes for all the info tied to those aspects of your life.
Pay attention to confirmations. As of today, agentic browsers still require some level of confirmation from the user to perform key actions (like processing a payment, sending an email, or updating a calendar entry). Pay close attention to them, so you can prevent your browser from doing something you don’t want it to do.
Use the “logged out” mode, if possible. As of this writing, at least one AI browser, Atlas, gives you the option to use the agent in the logged-out mode.i This limits its access to sensitive data and the risk of it taking actions on your behalf with your credentials.
If possible, disable “model learning.” By turning it off, you reduce the amount of personal info stored and processed by the AI provider for AI training purposes, which can minimize security and privacy risks.
Set privacy controls to the strictest options available. Further, understand what privacy policies the AI developer has in place. For example, some AI providers have policies that allow people to review your interactions with the AI as part of its training. These policies vary from company to company, and they tend to undergo changes. Keeping regular tabs on the privacy policy of the AI browser you use makes for a privacy-smart move.
Keep yourself informed. The capabilities, features, and privacy policies of AI-powered browsers continue to evolve rapidly. Set up news alerts about the AI browser you use and see if any issues get reported and, if so, how the AI developer has responded. Do routine searches pairing the name of the AI browser with “privacy.”

Howdy folks - former red teamer (a lot of my work is available under the rad9800 alias, if you're interested in malware - check it out!) now building the product to catch me/and in turn the many other adversaries running the same playbooks. We offer a paid deception platform, but I wanted to make a free tier actually useful.
What's free:
No credit card, no trial expiry. Just drop your email, get credentials, plant them where they shouldn't be touched. We have 12 other token types in the paid version, and will slowly expand these out in this edition depending on feedback/and increasing limits based on what's being used/what folk want.
Additionally - something unique about our AWS Access Keys in particular you can specify the username and they're allocated from a pool of 1000s of accounts so they're hard/impossible to fingerprint (prove me wrong, I'll be curious). When someone uses them, you get an alert (via email, which is why we need your email - else we wouldn't!) with:
Why these token types?
They're the ones I'd actually look for on an engagement. Hardcoded AWS creds in repos, SSH keys in backup folders, that .env file someone forgot to gitignore. If an attacker finds them, you want to reveal these internal breaches. I've written one or two blogs about "Read Teaming" and the trend (and more than happy to chat about it)
No catch?
The catch is I'm hoping some of you upgrade when you need more coverage/scale and/or feedback on this! But the free tier isn't crippled - it is very much the same detection pipeline we use for paying customers!

More than happy/excited to answer questions about the detection methodology or token placement strategies.
Happy December Patch Tuesday to all who celebrate. This month's patch party includes one Microsoft flaw under exploitation, plus two others listed as publicly known – but just 57 CVEs in total from Redmond.…
Microsoft today pushed updates to fix at least 56 security flaws in its Windows operating systems and supported software. This final Patch Tuesday of 2025 tackles one zero-day bug that is already being exploited, as well as two publicly disclosed vulnerabilities.
Despite releasing a lower-than-normal number of security updates these past few months, Microsoft patched a whopping 1,129 vulnerabilities in 2025, an 11.9% increase from 2024. According to Satnam Narang at Tenable, this year marks the second consecutive year that Microsoft patched over one thousand vulnerabilities, and the third time it has done so since its inception.
The zero-day flaw patched today is CVE-2025-62221, a privilege escalation vulnerability affecting Windows 10 and later editions. The weakness resides in a component called the “Windows Cloud Files Mini Filter Driver” — a system driver that enables cloud applications to access file system functionalities.
“This is particularly concerning, as the mini filter is integral to services like OneDrive, Google Drive, and iCloud, and remains a core Windows component, even if none of those apps were installed,” said Adam Barnett, lead software engineer at Rapid7.
Only three of the flaws patched today earned Microsoft’s most-dire “critical” rating: Both CVE-2025-62554 and CVE-2025-62557 involve Microsoft Office, and both can exploited merely by viewing a booby-trapped email message in the Preview Pane. Another critical bug — CVE-2025-62562 — involves Microsoft Outlook, although Redmond says the Preview Pane is not an attack vector with this one.
But according to Microsoft, the vulnerabilities most likely to be exploited from this month’s patch batch are other (non-critical) privilege escalation bugs, including:
–CVE-2025-62458 — Win32k
–CVE-2025-62470 — Windows Common Log File System Driver
–CVE-2025-62472 — Windows Remote Access Connection Manager
–CVE-2025-59516 — Windows Storage VSP Driver
–CVE-2025-59517 — Windows Storage VSP Driver
Kev Breen, senior director of threat research at Immersive, said privilege escalation flaws are observed in almost every incident involving host compromises.
“We don’t know why Microsoft has marked these specifically as more likely, but the majority of these components have historically been exploited in the wild or have enough technical detail on previous CVEs that it would be easier for threat actors to weaponize these,” Breen said. “Either way, while not actively being exploited, these should be patched sooner rather than later.”
One of the more interesting vulnerabilities patched this month is CVE-2025-64671, a remote code execution flaw in the Github Copilot Plugin for Jetbrains AI-based coding assistant that is used by Microsoft and GitHub. Breen said this flaw would allow attackers to execute arbitrary code by tricking the large language model (LLM) into running commands that bypass the guardrails and add malicious instructions in the user’s “auto-approve” settings.
CVE-2025-64671 is part of a broader, more systemic security crisis that security researcher Ari Marzuk has branded IDEsaster (IDE stands for “integrated development environment”), which encompasses more than 30 separate vulnerabilities reported in nearly a dozen market-leading AI coding platforms, including Cursor, Windsurf, Gemini CLI, and Claude Code.
The other publicly-disclosed vulnerability patched today is CVE-2025-54100, a remote code execution bug in Windows Powershell on Windows Server 2008 and later that allows an unauthenticated attacker to run code in the security context of the user.
For anyone seeking a more granular breakdown of the security updates Microsoft pushed today, check out the roundup at the SANS Internet Storm Center. As always, please leave a note in the comments if you experience problems applying any of this month’s Windows patches.
