  • Ransom Where?
    Ransom where? Holding data hostage with ransomware May 2019 Author With the evolution of digitization and increased interconnectivity, the cyberthreat landscape has transformed from merely a security and privacy concern to a danger much more insidious by nature — ransomware. Ransomware is a type of malware that is designed to encrypt, Imani Barnes Analyst 646.572.3930 destroy or shut down networks in exchange [email protected] for a paid ransom. Through the deployment of ransomware, cybercriminals are no longer just seeking to steal credit card information and other sensitive personally identifiable information (PII). Instead, they have upped their games to manipulate organizations into paying large sums of money in exchange for the safe release of their data and control of their systems. While there are some business sectors in which the presence of this cyberexposure is overt, cybercriminals are broadening their scopes of potential victims to include targets of opportunity1 across a multitude of industries. This paper will provide insight into how ransomware evolved as a cyberextortion instrument, identify notorious strains and explain how companies can protect themselves. 1 WIRED. “Meet LockerGoga, the Ransomware Crippling Industrial Firms” March 25, 2019; https://www.wired.com/story/lockergoga-ransomware-crippling-industrial-firms/. 2 Ransom where? | May 2019 A brief history of ransomware The first signs of ransomware appeared in 1989 in the healthcare industry. An attacker used infected floppy disks to encrypt computer files, claiming that the user was in “breach of a licensing agreement,”2 and demanded $189 for a decryption key. While the attempt to extort was unsuccessful, this attack became commonly known as PC Cyborg and set the archetype in motion for future attacks.

  • The Uses of Animation 1
    The Uses of Animation 1 1 The Uses of Animation ANIMATION Animation is the process of making the illusion of motion and change by means of the rapid display of a sequence of static images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon. Animators are artists who specialize in the creation of animation. Animation can be recorded with either analogue media, a flip book, motion picture film, video tape,digital media, including formats with animated GIF, Flash animation and digital video. To display animation, a digital camera, computer, or projector are used along with new technologies that are produced. Animation creation methods include the traditional animation creation method and those involving stop motion animation of two and three-dimensional objects, paper cutouts, puppets and clay figures. Images are displayed in a rapid succession, usually 24, 25, 30, or 60 frames per second. THE MOST COMMON USES OF ANIMATION Cartoons The most common use of animation, and perhaps the origin of it, is cartoons. Cartoons appear all the time on television and the cinema and can be used for entertainment, advertising, 2 Aspects of Animation: Steps to Learn Animated Cartoons presentations and many more applications that are only limited by the imagination of the designer. The most important factor about making cartoons on a computer is reusability and flexibility. The system that will actually do the animation needs to be such that all the actions that are going to be performed can be repeated easily, without much fuss from the side of the animator.

  • JSON Application Programming Interface for Discrete Event Simulation Data Exchange
    JSON Application Programming Interface for Discrete Event Simulation data exchange Ioannis Papagiannopoulos Enterprise Research Centre Faculty of Science and Engineering Design and Manufacturing Technology University of Limerick Submitted to the University of Limerick for the degree of Master of Engineering 2015 1. Supervisor: Prof. Cathal Heavey Enterprise Research Centre University of Limerick Ireland ii Abstract This research is conducted as part of a project that has the overall aim to develop an open source discrete event simulation (DES) platform that is expandable, and modular aiming to support the use of DES at multi-levels of manufacturing com- panies. The current work focuses on DES data exchange within this platform. The goal of this thesis is to develop a DES exchange interface between three different modules: (i) ManPy an open source discrete event simulation engine developed in Python on the SimPy library; (ii) A Knowledge Extraction (KE) tool used to populate the ManPy simulation engine from shop-floor data stored within an Enterprise Requirements Planning (ERP) or a Manufacturing Execution System (MES) to allow the potential for real-time simulation. The development of the tool is based on R scripting language, and different Python libraries; (iii) A Graphical User Interface (GUI) developed in JavaScript used to provide an interface in a similar manner to Commercial off-the-shelf (COTS) DES tools. In the literature review the main standards that could be used are reviewed. Based on this review and the requirements above, the data exchange format standard JavaScript Object Notation (JSON) was selected. The proposed solution accom- plishes interoperability between different modules using an open source, expand- able, and easy to adopt and maintain, in an all inclusive JSON file.
