...It works by abusing the NAT’s Application Level Gateway (ALG) logic and connection tracking, combined with browser capabilities like WebRTC, precise packet fragmentation or boundary control, and packet injection techniques. The attack is able to bypass browser port restrictions by fragmenting or massaging packets so that the “exploit payload” lands in a packet boundary that gets parsed by the NAT/ALG as a legitimate protocol packet (e.g. SIP or H.323). Once successful, the NAT/firewall is deceived into opening a “hole” (port forwarding) back to the internal host, enabling the attacker to connect directly to internal services.

Pixload is a collection of tools for creating and injecting payloads into image files using steganographic techniques to embed hidden content in common image formats. It supports BMP, GIF, JPG, PNG, and WebP formats and offers command-line utility for generating or modifying images with embedded payloads. If the target image exists, it can inject into it; otherwise, it generates a new one. Offers separate utilities per format (e.g., bmp.pl, gif.pl, jpg.pl, png.pl) for injection or creation....
