The open-source command-and-control (C2) framework known as AdaptixC2 is being used by a growing number of threat actors, some of whom are related to Russian ransomware gangs. AdaptixC2 is an emerging extensible post-exploitation and adversarial emulation framework designed for penetration testing. While the server component is written in Golang, the GUI Client is written in C++ QT for

The X-59 successfully completed its inaugural flight—a step toward developing quieter supersonic jets that could one day fly customers more than twice as fast as commercial airliners.

Silent Push wars of Russian hackers exploiting Adaptix, a pentesting tool built for Windows, Linux, and macOS, in ransomware campaigns.

The comfort zone in cybersecurity is gone. Attackers are scaling down, focusing tighter, and squeezing more value from fewer, high-impact targets. At the same time, defenders face growing blind spots — from spoofed messages to large-scale social engineering. This week’s findings show how that shrinking margin of safety is redrawing the threat landscape. Here’s what’s

Cybersecurity researchers have uncovered yet another active software supply chain attack campaign targeting the npm registry with over 100 malicious packages that can steal authentication tokens, CI/CD secrets, and GitHub credentials from developers' machines. The campaign has been codenamed PhantomRaven by Koi Security. The activity is assessed to have begun in August 2025, when the first

**Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?** One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

### Summary A command-injection vulnerability lets any attacker who can influence the server_name field of an MCP execute arbitrary OS commands on Windows hosts that run fastmcp install cursor ### Details 1. generate_cursor_deeplink(server_name, …) embeds server_name verbatim in a cursor://…?name= query string. 2. open_deeplink() is invoked with shell=True only on Windows. That calls cmd.exe /c start <deeplink>. 3. Any cmd metacharacter inside server_name (&, |, >, ^, …) escapes the start command and spawns an attacker-chosen process. ### PoC server.py ``` import random from fastmcp import FastMCP mcp = FastMCP(name="test&calc") @mcp.tool def roll_dice(n_dice: int) -> list[int]: """Roll `n_dice` 6-sided dice and return the results.""" return [random.randint(1, 6) for _ in range(n_dice)] if __name__ == "__main__": mcp.run() ``` then run in the terminal: `fastmcp install cursor server.py` ### Impact OS Command / Shell Injection (CWE-78) Every Windows host that runs f...

### Summary FastMCP documentation [covers the scenario](https://gofastmcp.com/integrations/azure) where it is possible to use Entra ID or other providers for authentication. In this context, because Entra ID does not support Dynamic Client Registration (DCR), the FastMCP-hosted MCP server is acting as the authorization provider, as declared in the Protected Resource Metadata (PRM) document hosted on the server. For example, on a local MCP server, it may be hosted here: ```http http://localhost:8000/.well-known/oauth-protected-resource ``` And the JSON representation of the PRM document: ```json { "resource": "http://localhost:8000/mcp", "authorization_servers": [ "http://localhost:8000/" ], "scopes_supported": [ "User.Read", "email", "openid", "profile" ], "bearer_methods_supported": [ "header" ] } ``` Notice that the `authorization_servers` field contains the MCP server itself - it acts as an **OAuth Client** to the downstream authorization ...

Cybersecurity researchers have flagged a new security issue in agentic web browsers like OpenAI ChatGPT Atlas that exposes underlying artificial intelligence (AI) models to context poisoning attacks. In the attack devised by AI security company SPLX, a bad actor can set up websites that serve different content to browsers and AI crawlers run by ChatGPT and Perplexity. The technique has been
