Hash-Based Threat Detection for Real-Time Phishing And Ransomware Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cybersecurity systems, including endpoint detection and remediation (EDR) and browser isolation systems, fail to detect and prevent phishing attacks and ransomware threats in real-time, leading to significant delays in threat detection and potential data breaches, with EDR systems taking up to 16 days and browser isolation systems being susceptible to newly created URLs and performance overheads.
Innovation Solution
A real-time ransom and security breach detection system that generates hashes of URL links and HTML code to determine their maliciousness, terminating access to potentially harmful links and generating reports, utilizing decentralized block-chain ledgers for data storage and client-side processing to prevent breaches within seconds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional EDR systems are used to detect security breaches, then detection capability is provided, but detection time is delayed (up to 16 days)
Solution Approach 1:
The system performs preliminary hashing of URL links when they are first received or encountered, storing the hashes in advance. When a user interacts with a link, the system immediately compares the link's hash against stored hashes to determine maliciousness, eliminating the need for time-consuming post-infection analysis.
Solution Approach 2:
The patent replaces the mechanical monitoring and analysis system of traditional EDR with a cryptographic hash-based detection mechanism. By converting URL links into fixed-length hashes and comparing these digital fingerprints, the system achieves instantaneous detection without the overhead of traditional file monitoring and behavioral analysis.
2Reliability
If browser isolation systems are implemented to prevent security breaches, then some protection is provided, but the system is susceptible to newly created URLs and experiences performance overhead
Solution Approach 1:
The system automatically generates cryptographic hashes for URL links and maintains a self-updating database of malicious link hashes. The hashing mechanism inherently adapts to new URLs without requiring manual whitelist/blacklist updates, as any new malicious link will generate a unique hash that can be detected when added to the system's reference database.
3Reliability
If browser isolation systems are used to create virtual environments, then security protection is improved, but system resource consumption increases
Solution Approach 1:
The patent extracts the essential security function from the complex browser isolation infrastructure by isolating only the URL validation process. Instead of creating full virtual machine environments for every browsing session, the system extracts and validates only the critical element (the URL link) using cryptographic hashing, thereby achieving security protection with minimal resource overhead.

AI summary
The real-time ransom and security breach detection and prevention system empowers users and system administrators by providing real-time threat detection and prevention by detecting any phishing links, malicious executables and objects, and manipulation of authentication tokens that could potentially escalate a threat into ransom attacks, security breaches or other cyber attacks, and take immediate action by blocking and reporting the potential security breach before escalating into a real attack. The real-time ransom and security breach detection and prevention system generates a first hash of the link, executable, object, or authentication token. Utilizing this generated first hash, the real-time ransom and security breach detection and prevention system calculates a second hash upon user interaction or at runtime and compares the two unique hashes to determine if the link, executable, object, or authentication token is corrupt and terminates the gateway to prevent the cyber-threat from infecting the system.
