Hacktricks 179 ✦ Extended & Safe

is the standard port for the Border Gateway Protocol (BGP) , the fundamental protocol responsible for global internet routing. Because HackTricks functions as a leading cybersecurity knowledge base for penetration testers and red teamers, a "HackTricks style" guide for port 179 covers the core reconnaissance, enumeration, vulnerability testing, and defense mechanisms for BGP endpoints. Misconfigured BGP infrastructure can lead to catastrophic consequences, including global route leaking, denial-of-service (DoS) conditions, and highly targeted BGP hijacking attacks. Protocol Overview

The vulnerability occurs when an application validates user input applying security filters or data normalization, but an attacker can exploit this order of operations by submitting specially crafted input that passes the initial validation but becomes malicious after the application's filtering and normalization process. For example, an application might check for malicious strings, then URL-decode the input. An attacker could send a URL-encoded version of a forbidden string that passes the initial check but is decoded into a malicious payload afterward.

Based on the naming convention, "Hacktricks 179" likely refers to . In the HTB archive, Machine 179 is named "Blocky" . hacktricks 179

: An attacker compromises an edge router or establishes an unauthorized peering session. They broadcast an UPDATE message claiming ownership of an IP prefix assigned to another entity.

Because BGP relies on a single continuous TCP session, breaking that connection forces the router to dump its routing table for that peer, causing severe network "flapping" and downtime. is the standard port for the Border Gateway

The keyword refers directly to the security methodology for auditing TCP Port 179 , the standard port dedicated to the Border Gateway Protocol (BGP) . As the fundamental protocol that determines how data packets travel across the global internet between Autonomous Systems (AS), BGP serves as the primary backbone of internet infrastructure. However, because it was originally designed on a system of implicit trust, an exposed or poorly managed BGP interface poses immense security risks to large networks and ISPs.

: The BGP session is fully operational. Routing updates ( UPDATE packets) can now be exchanged. 3. High-Impact Attack Vectors A. BGP Route Hijacking Based on the naming convention, "Hacktricks 179" likely

Software like Quagga, FRRouting, or OpenBGPD may have CVEs (Common Vulnerabilities and Exposures) that can lead to remote code execution (RCE) or service crashes. 5. Security Best Practices for Port 179
