### 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...

Organizations in Ukraine have been targeted by threat actors of Russian origin with an aim to siphon sensitive data and maintain persistent access to compromised networks.

Cybersecurity researchers have discovered a set of 10 malicious npm packages that are designed to deliver an information stealer targeting Windows, Linux, and macOS systems. "The malware uses four layers of obfuscation to hide its payload, displays a fake CAPTCHA to appear legitimate, fingerprints victims by IP address, and downloads a 24MB PyInstaller-packaged information stealer that harvests

### Summary Sliver's custom Wireguard netstack doesn't limit traffic between Wireguard clients, this could lead to: 1. Leaked/recovered keypair (from a beacon) being used to attack operators. 2. Port forwardings usable from other implants. ### Details 1. Sliver treat operators' Wireguard config and beacon/session's Wireguard config equally, they both connect to the wireguard listener created from the CLI. 2. The current netstack implementation does not filter traffic between clients. I think this piece of code handle traffic between clients, from experimental results clients can ping and connect to each other freely, and I didn't see any filtering here either: ``` File: server\c2\wireguard.go 246: func socketWGWriteEnvelope(connection net.Conn, envelope *sliverpb.Envelope) error { 247: data, err := proto.Marshal(envelope) 248: if err != nil { 249: wgLog.Errorf("Envelope marshaling error: %v", err) 250: return err 251: } 252: dataLengthBuf := new(bytes.Buffer) 253: binary.W...

Threat actors tied to North Korea have been observed targeting the Web3 and blockchain sectors as part of twin campaigns tracked as GhostCall and GhostHire. According to Kaspersky, the campaigns are part of a broader operation called SnatchCrypto that has been underway since at least 2017.
