Fraud Response System Using Proxy Chains and IP Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of spam and phishing activities on the internet poses a significant challenge due to the anonymity of spammers and phishers, making it difficult to effectively prosecute and prevent fraudulent activities such as identity theft and unauthorized transactions, as these actors often use transient and compromised servers to operate.
Innovation Solution
Implementing a system that generates and transmits multiple HTTP requests to a suspected fraudulent server, making them appear to originate from diverse IP blocks, thereby overwhelming the server and rendering it unable to process legitimate requests, while using proxy chains and dilution engines to obscure the source of these requests and prevent filtering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple HTTP requests are transmitted from diverse IP blocks to overwhelm the fraudulent server, then the server's ability to engage in fraudulent activities is diminished, but the complexity of the response system increases
Solution Approach 1:
The system segments the response traffic by distributing HTTP requests across multiple diverse IP blocks, making the fraud prevention mechanism more effective while managing complexity through structured segmentation of response sources
Solution Approach 2:
Proxy chains are introduced as intermediary components to obscure the source of requests and prevent filtering, resolving the contradiction by adding a layer of mediation that enhances effectiveness without directly increasing core system complexity
2Adaptability or versatility
If proxy chains and dilution engines are used to obscure the source of requests, then the ability to prevent filtering is improved, but the device complexity increases
Solution Approach 1:
Proxy chains serve as intermediary components that obscure the source of requests, enhancing adaptability to prevent filtering while managing complexity through standardized intermediary patterns
Solution Approach 2:
The system adds dimensional complexity by introducing multiple layers of proxy intermediaries and dilution engines, transforming a simple request-response model into a multi-dimensional obscured communication path that enhances filtering resistance
3Object-generated harmful factors
If the server resources are occupied by multiple HTTP requests, then ongoing fraudulent behavior is prevented, but legitimate requests may be blocked
Solution Approach 1:
The system applies partial action by occupying only sufficient server resources to prevent fraud without completely disabling the server, and uses excessive action through diverse IP blocks to ensure legitimate traffic can still penetrate the obstruction
Solution Approach 2:
Instead of trying to identify and block fraudulent requests, the system inverts the approach by making it difficult to distinguish fraudulent from legitimate requests through diverse IP block origins, thereby preventing fraud through obscurity rather than detection

AI summary
Solutions (including inter alia, systems, methods and software) for dealing with online fraud. Certain of these solutions provide enhanced responses to an identified instance of online fraud. Such enhanced responses can incorporate one or more of a variety of strategies for defeating an attempt by a server to filter and/or otherwise avoid responses to its fraudulent activity. Merely by way of example, responses may be disguised (e.g., by transmitting the responses from a variety of computers, by transmitting responses that appear to originate from a computer different than the actual source of the responses, etc.). In some cases, a response strategy may be implemented that forces the server (and/or an operator thereof) to choose between accepting the responses and blocking potential responses from the targets of the fraudulent scheme.
