Cybercrime is the highest threat to every private company and government agency in the world. Using synergistic threats to attack provides many success alternatives that lead to the same goal, which is to take over the network and carry out illegal mining activities using CPU resources from the victim’s computer. One of the main motives for the success of this criminal business is its relatively low cost and high return of investment. Using the infection chain method in carrying out cryptocurrency mining malware attacks with fileless techniques involves loading malicious code into system memory. Monero (XMR) is by far the highest popular cryptocurrency among threat actor installing mining malware because it comes with full anonymity and resistance to an application-specific circuit mining (ASIC). This work proposes a better method for classifying conventional malware and cryptocurrency mining malware. On the other hand, grouping specific of suitable features extracted from the sources of EMBER dataset shown as malware and need to categorize as a cryptocurrency mining malware. The proposed approach is defining a better algorithm for enhancing accuracy and efficiency for cryptocurrency mining malware detection.
Mozilla Corporation has recently released a Linuxbased open source operating system, namely Firefox OS. The arrival of this Firefox OS has created new challenges, concentrations and opportunities for digital investigators.Currently, Firefox OS is still not fully supported by most of the existing mobile forensic tools. Even when the phone is detected as Android, only pictures from removable card was able to be captured. Furthermore, the internal data acquisition is still not working. Therefore, there are very huge opportunities to explore the Firefox OS on every stages of mobile forensic procedures. This paper will present an approach for mobile forensic data acquisition in a forensically sound manner from a Firefox OS running device. This approach will largely use the UNIX dd command to create a forensic image from the Firefox OS running device.
The advancement of smartphone technology has attracted many companies in developing mobile operating system (OS). Mozilla Corporation recently released Linux-based open source mobile OS, named Firefox OS. The emergence of Firefox OS has created new challenges, concentrations and opportunities for digital investigators. In general, Firefox OS is designed to allow smartphones to communicate directly with HTML5 applications using JavaScript and newly introduced WebAPI. However, the used of JavaScript in HTML5 applications and solely no OS restriction might lead to security issues and potential exploits. Therefore, forensic analysis for Firefox OS is urgently needed in order to investigate any criminal intentions. This paper will present an overview and methodology of mobile forensic procedures in forensically sound manner for Firefox OS.
The continuous advancements of blockchain applications impose constant improvements on their technical features. Particularly immutability, a highly secure blockchain attribute forbidding unauthorized or illicit data editing or deletion, which functions as crucial blockchain security. Nonetheless, the security function is currently being challenged due to improper data stored, such as child pornography, copyright violation, and lately the enaction of the “Right to be Forgotten (RtbF)” principle disseminated by the General Data Protection Regulation (GDPR), where it requires blockchain data to be redacted to suit current applications’ urgent demands, and even compliance with the regulation is a challenge and an unfeasible practice for various blockchain technology providers owing to the immutability characteristic. To overcome this challenge, mutable blockchain is highly demanded to solve previously mentioned issues, where controlled and supervised amendments to certain content within constrained privileges granted are suggested by several researchers through numerous blockchain redaction mechanisms using chameleon and non-chameleon hashing function approaches, and methods were proposed to achieve reasonable policies while ensuring high blockchain security levels. Accordingly, the current study seeks to thoroughly define redaction implementation challenges and security properties criteria. The analysis performed has mapped these criteria with chameleon-based research methodologies, technical approaches, and the latest cryptographic techniques implemented to resolve the challenge posed by the policy in which comparisons paved current open issues, leading to shaping future research directions in the scoped field.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
