CUING 2021

The 5th International Workshop on Criminal Use of Information Hiding (CUING 2021)

to be held in conjunction with the 16 th International Conference on Availability, Reliability and Security
(ARES 2021 – )

August 17 – August 20, 2021

With the constant rise of the number of Internet users, available bandwidth and an increasing number of services shifting into the connected world, criminals are increasingly active in the virtual world. With improving defensive methods cybercriminals have to utilize more and more sophisticated ways to perform their malicious activities. While protecting the privacy of users, many technologies used in current malware and network attacks have been abused in order to allow criminals to carry out their activities undetected. This poses a lot of new challenges for digital forensics analysts, academics, law enforcement agencies (LEAs), and security professionals.

The aim of the Third International Workshop on Criminal Use of Information Hiding (CUIng) is to bring together researchers, practitioners, law enforcement representatives, and security professionals in the area of analysis of information hiding. However data hiding is understood here in a wider manner than in the academic world i.e. all techniques that pertain to camouflaging/masking/hiding various types of data (e.g. identities, behavior, communication, etc.) are included here. This means not only digital steganography/covert channels but also obfuscation/anti-forensics techniques and even underground networks (darknets) or activities related to behavior impersonation or mimicking. This will allow to present a more complete picture on novel research regarding the use of data and communication hiding methods in criminal environments and discuss ideas for fighting misuse of privacy enhancing technologies.

Moreover, this year the CUING workshop is co-organized with the SIMARGL (Secure Intelligent Methods for Advanced RecoGnition of malware and stegomalware) H2020 project.

Stegom alware: what is it and what we can do?

Dr. Luca Caviglione, IMATI CNR, Italy

Abstract : Information hiding and steganographic techniques are increasingly used by attackers to create a new-wave of threats (often called stegomalware) able to covertly exfiltrate data, obfuscate their presence, retrieve malicious payloads or bypass security mechanisms. Despite the increasing volume of attacks, the degree of sophistication, and the growing attention from security-oriented firms, stegomalware is often neglected for a twofold reason. First, its emerging nature still requires precise investigation methodologies and conceptual devices. Second, each hiding technique is tightly coupled with the digital entity exploited to conceal the information. In this talk, we will review some real-world threats exploiting information hiding with emphasis on the used techniques and attack models. Then, we will discuss possible countermeasures, focusing on the challenges arising by the need of inspecting many heterogenous digital contents (e.g., images, network traces or execution flows) without endangering the quality perceived by users. Lastly, we will also present some ideas developed within the H2020 Project SIMARGL – Secure Intelligent Methods for Advanced RecoGnition of malware, which aims at mitigating risks of information-hiding-capable attacks.
