Flare researchers analyzed 2,889 underground posts to understand how carders are utilizing residential proxies. The findings indicate that while residential IP addresses are critical, they are increasingly seen as unreliable and require careful selection and combination with other digital identity tools.
Flare researchers conducted an analysis of 2,889 unique posts across approximately 545 threads in underground forums over the past two years. These discussions range from operational guides and troubleshooting to advertisements for 'clean' proxy services, highlighting the evolving landscape of proxy use in carding.
Historically, residential proxies were viewed as simple anonymity tools. However, they are now recognized as part of a broader identity-simulation stack, which includes device fingerprints and billing information. The study suggests that carders are increasingly cautious, evaluating proxies based on their history and reputation.
The conversation among carders has shifted towards achieving geographic consistency across various identity factors such as time zone, browser language, and ZIP code. This holistic approach is necessary as carders seek to create a convincing digital identity.
Researchers found that the proxy market for residential IPs is becoming fragile, with overused IP addresses gaining poor reputations and financial services blocking entire ranges. Carders must be selective in their proxies to avoid detection, making the role of residential proxies more complex.
The demand for dependable 'clean' residential proxies has led to the emergence of secondary markets. These services are seen as essential for carders to access financial platforms without raising red flags. This trend underscores the changing dynamics within the carding ecosystem.
The findings suggest that defenders should reconsider how they interpret residential traffic. Rather than viewing it as an indication of legitimacy, they should treat it as context for potentially fraudulent behavior. This shift in perspective may enhance detection strategies in combating cybercrime.
