Recently, ransomware has earned itself an infamous reputation as a force to reckon with in the cybercrime landscape. However, cybercriminals are adopting other unconventional means to seamlessly attain proceeds of cybercrime with little effort. Cybercriminals are now acquiring cryptocurrencies directly from benign Internet users without the need to extort a ransom from them, as is the case with ransomware. This paper investigates advances in the cryptovirology landscape by examining the state-of-the-art cryptoviral attacks. In our approach, we perform digital autopsy on the malware's source code and execute the different malware variants in a contained sandbox to deduce static and dynamic properties respectively. We examine three cryptoviral attack structures: browser-based crypto mining, memory resident crypto mining and cryptoviral extortion. These attack structures leave a trail of digital forensics evidence when the malware interacts with the file system and generates noise in form of network traffic when communicating with the C2 servers and crypto mining pools. The digital forensics evidence, which essentially are IOCs include network artifacts such as C2 server domains, IPs and cryptographic hash values of the downloaded files apart from the malware hash values. Such evidence can be used as seed into intrusion detection systems for mitigation purposes.

This study identified the characteristics of the subculture aspects that led to the success of luxury brands and analyzed the implications of those aspects. For this, semantic analysis in a socio-cultural context was performed. Additionally, this study took the theoretical background, the change in subculture and post-subculture, the digital youth generation, and the change in the meaning of subculture style into consideration. The subculture style aspect and its meaning in luxury fashion brands were analyzed as follows: First, there are challenges that betray the legitimacy or values of luxury brands. Through this, the brand gained recognition and increased sales, and the designer gained a reputation as an innovative creative director. It can be seen that more successful branding was promoted by securing a more subcultured fandom. Second, by combining subculture image fragments, these brands cater to the diverse tastes of a myriad of subcultures. This maximizes commercial profits. Third, most promotional marketing activities are collaborative and done digitally, which allows for a wider customer base, but the difference is in digital capabilities. Limited editions or application use on social networks can act as another driver. It is said that the distinction in high-priced luxury brands is not only driven by economic power but also by sub-cultural capital and digital ability.

Tempered electronic contents have multiplied in last few years, thanks to the emergence of sophisticated artificial intelligence(AI) algorithms. Deepfakes (fake footage, photos, speech, and videos) can be a frightening and destructive phenomenon that has the capacity to distort the facts and hamper reputation by presenting a fake reality. Evidence of ownership or authentication of digital material is crucial for combating the fabricated content influx we are facing today. Current solutions lack the capacity to track digital media's history and provenance. Due to the rise of misrepresentation created by technologies like deepfake, detection algorithms are required to verify the integrity of digital content. Many real-world scenarios have been claimed to benefit from blockchain's authentication capabilities. Despite the scattered efforts surrounding such remedies, relatively little research has been undertaken to discover where blockchain technology can be used to tackle the deepfake problem. Latest blockchain based innovations such as Smart Contract, Hyperledger fabric can play a vital role against the manipulation of digital content. The goal of this paper is to summarize and discuss the ongoing researches related to blockchain's capabilities to protect digital content authentication. We have also suggested a blockchain (smart contract) dependent framework that can keep the data integrity of original content and thus prevent deepfake. This study also aims at discussing how blockchain technology can be used more effectively in deepfake prevention as well as highlight the current state of deepfake video detection research, including the generating process, various detection algorithms, and existing benchmarks.

An international survey of over 3600 academic researchers examined how trustworthiness is determined when making decisions on scholarly reading, citing, and publishing in the digital age and whether social media and open access publications are having an impact on judgements. In general, the study found that traditional scholarly methods and criteria remain important across the board. However, there are significant differences between younger (age 30 & under) and older researchers (over 30). Thus younger researchers: a) expend less effort to obtain information and more likely to compromise on quality in their selections; b) view open access publishing much more positively as it offers them more choices and helps to establish their reputation more quickly; c) compensate for their lack of experience by relying more heavily on trust markers and proxies, such as impact factors; d) use all the outlets available in order to improve the chances of getting their work published and, in this respect, make the most use of the social media with which they are more familiar.

Vincenzo Scamozzi as the successor of Palladio stands as a major accomplishment of the task of cleanup to the classicism in 16th century. In addition, unlike the trend seen over Palladian, he shows succession and change of Renaissance villa. "L'Idea dell' Archittectura Universale; The Idea of a Universal Architecture"(1615) is a book of Scamozz's representative. This book is represented his idea for a residential building. His concepts for a residential building were analyzed through the analysis of his book and work. Scamozzi thought that domestic architecture should be designed according to he owner's social status and reputation. These concepts as decorum and this is divided into three categories. This is a threefold order, the first category and highest encompassing reigning princess and their families, who were more or less regarded as God's representatives on earth. The second category comprised noblemen and high office holders whose houses were to be, in all respects, a degree less grand, costly and dignified than the prince's residence. The third category was made up of prominent citizens and wealthy merchants whose houses were to have only moderate commoner did not come into this classification at all. - the magnifiche, honorevoli, and commune style of speech.

Customer complaints handling helps organizations to retain existing customers and attract new customers, as well. As Voice of the Customer (VOC) is one of the main sources of customer complaints, many organizations utilize VOC to enhance customer satisfaction. Effective management of VOC has been proved as one of the best ways to maintain organization's brand image and reputation. In spite of its importance, little has been reported on the utilization of VOC to detect faults in a telecommunication industry. In this paper, association rule mining based on VOC is used to identify root fault causes of a telecommunications network. To do that, VOC of a Communication Service Provider has been collected first. Then, association rule mining has also been conducted with various support and confidence levels. As a result, root fault causes of the telecommunications network can be identified. It is expected that this study can be used as a basis for decisions about customer satisfaction management such as preventive maintenances or reduction of the customer maintenance cost.
