Your IP, Their Traffic
September 30, 2026 · Gen Digital · Severity: MEDIUM
This article explores the hidden supply chain of residential proxies, where cybercriminals use legitimate home IP addresses to route malicious traffic. It details how brokers acquire these IPs from unsuspecting users and sell access to threat actors, enabling attacks that bypass conventional security measures. 📌 **Analyst Note:** Residential proxy networks represent a growing threat that complicates threat detection and attribution. Organizations should invest in behavioral analysis and reputation-based defenses rather than relying solely on IP blacklists to counter this evolving tactic.
Key Takeaways
- Residential proxies are being used to mask malicious traffic by routing it through legitimate home IP addresses, creating a hidden supply chain that cybercriminals exploit for anonymity and evasion.
- The supply chain involves brokers who acquire residential IPs from users, often through deceptive apps or incentives, and then sell access to threat actors for activities like credential stuffing and ad fraud.
- This practice undermines traditional IP-based blocking and geolocation defenses, making it harder for organizations to distinguish between legitimate users and attackers using hijacked residential connections.
