Crossfire [best] | Xhook

For offensive operators, exfiltrating large datasets past a Data Loss Prevention (DLP) proxy is difficult. XHook Crossfire intercepts the DLP’s recv function (via a kernel driver) and the target process’s send function simultaneously. It then orchestrates a crossfire: The target sends 1KB of real data, then 100KB of decoy base64 noise. The DLP, exhausted by the crossfire of valid and invalid streams, either crashes or allows the real data through.

: XHOOK markets its tool as a "private" hack, which developers often claim reduces the likelihood of detection compared to public, free-to-download alternatives. How to Access xhook crossfire

While standard CORS attacks rely on the server reflecting the Origin header blindly (e.g., Access-Control-Allow-Origin: * or reflecting a specific evil domain), Xhook Crossfire describes a scenario where an attacker leverages a persistent XSS vulnerability (or a "hooked" browser session) to bypass CORS restrictions, effectively turning the user's browser into a proxy for stealing sensitive data from vulnerable domains. For offensive operators, exfiltrating large datasets past a

Xhook Crossfire represents the intersection of and Stored Cross-Site Scripting . By utilizing a "hook" inside the target origin, attackers bypass the protections offered by the Same-Origin Policy and CORS headers, effectively turning the victim's browser into a tool for data exfiltration. The DLP, exhausted by the crossfire of valid
