Crypto-ransomware detection using machine learning models in file-sharing network scenarios with encrypted traffic
نویسندگان
چکیده
Ransomware is considered as a significant threat for home users and enterprises. In corporate scenarios, users’ computers usually store only system program files, while all the documents are accessed from shared servers. these one crypto-ransomware infected host capable of locking access to files it has to, which can be whole set workgroup users. We propose tool detect block activity based on file-sharing traffic analysis. The monitors exchanged between clients file servers using machine learning techniques searches patterns in that betray ransomware actions reading overwriting files. This first proposal designed work not clear text protocols but also encrypted protocols. extract features network describe opening, closing, modifying allow differentiation high benign applications. train test detection model large more than 70 binaries 33 different strains 2,400 h ‘not infected’ real results reveal proposed described, including those used training phase. paper provides validation algorithm by studying false positive rate amount information user could encrypt before being detected.

Realtime Encrypted Traffic Identification using Machine Learning
Accurate network traffic identification plays important roles in many areas such as traffic engineering, QoS and intrusion detection etc. The emergence of many new encrypted applications which use dynamic port numbers and masquerading techniques causes the most challenging problem in network traffic identification field. One of the challenging issues for existing traffic identification methods ...
متن کاملSoftware-Defined Networking-based Crypto Ransomware Detection Using HTTP Traffic Characteristics
Ransomware is currently the key threat for individual as well as corporate Internet users. Especially dangerous is crypto ransomware that encrypts important user data and it is only possible to recover it once a ransom has been paid. Therefore devising efficient and effective countermeasures is a rising necessity. In this paper we present a novel Software-Defined Networking (SDN) based detectio...
متن کاملDetecting Encrypted Traffic: A Machine Learning Approach
Detecting encrypted traffic is increasingly important for deep packet inspection (DPI) to improve the performance of intrusion detection systems. We propose a machine learning approach with several randomness tests to achieve high accuracy detection of encrypted traffic while requiring low overhead incurred by the detection procedure. To demonstrate how effective the proposed approach is, the p...
متن کاملFile Detection in Network Traffic Using Approximate Matching
Virtually every day data breach incidents are reported in the news. Scammers, fraudsters, hackers and malicious insiders are raking in millions with sensitive business and personal information. Not all incidents involve cunning and astute hackers. The involvement of insiders is ever increasing. Data information leakage is a critical issue for many companies, especially nowadays where every empl...
متن کاملFile Detection On Network Traffic Using Approximate Matching
In recent years, Internet technologies changed enormously and allow faster Internet connections, higher data rates and mobile usage. Hence, it is possible to send huge amounts of data / files easily which is often used by insiders or attackers to steal intellectual property. As a consequence, data leakage prevention systems (DLPS) have been developed which analyze network traffic and alert in c...
