WhatsApp is a giant mobile instant message IM application with over 1billion users. The huge usage of IM like WhatsApp through giant smart phone “Android” makes the digital forensic researchers to study deeply. The artefacts left behind in the smartphone play very important role in any electronic crime, or any terror attack. “WhatsApp” as a biggest IM in the globe is considered to be very important resource for information gathering about any digital crime. Recently, end-to-end encryption and many other important features were added and no device forensic analysis or network forensic analysis studies have been performed to the time of writing this paper. This paper explains how can we able to extract the Crypt Key of “WhatsApp” to decrypt the databases and extract precious artefacts resides in the android system without rooting the device. Artefacts that extracted from the last version of WhatsApp have been analysed and correlate to give new valuable evidentiary traces that help in investigating. Many hardware and software tools for mobile and forensics are used to collect as much digital evidence as possible from persistent storage on android device. Some of these tools are commercial like UFED Cellebrite and Andriller, and other are open source tools such as autopsy, adb, WhatCrypt. All of these tools that forensically sound accompanied this research to discover a lot of artefacts resides in android internal storage in WhatsApp application.

As virtually all Europe's major socialist parties re-aligned with their own national governments with the outbreak of World War I, Irish socialist and trade unionist James Connolly found himself internationally isolated by his vociferous opposition to the war. Within Ireland, however, Connolly's energetic and relentless calls to interrupt the imperial transportation and communications networks on which the ‘carnival of murder’ in Europe relied had the converse effect, drawing him into alignment with certain strains of Irish nationalism. Connolly and other socialist republican stalwarts like Helena Molony and Michael Mallin made common cause with advanced Irish nationalism, the one other constituency unamenable to fighting for England under any circumstances. This centripetal gathering together of two minority constituencies – both intrinsically opposed, if not to the war itself, certainly to Irish Party leader John Redmond's offering up of the Irish Volunteers as British cannon fodder – accounts for the “remarkably diverse” social and ideological character of the small executive body responsible for the planning of the Easter Rising: the Irish Republican Brotherhood's military council. In effect, the ideological composition of the body that planned the Easter Rising was shaped by the war's systematic diversion of all individuals and ideologies that could be co-opted by British imperialism through any possible argument or material inducement. Although the majority of those who participated in the Rising did not share Connolly's anti-war, pro-socialist agenda, the Easter 1916 Uprising can nonetheless be understood as, among other things, a near letter-perfect instantiation of Connolly's most steadfast principle: that it was the responsibility of every European socialist to throw onto the gears of the imperialist war machine every wrench on which they could lay their hands.

Chris Milan, Managing Director of Southeastern Region at Tribridge, Inc., was drumming away at the annual “Connect” conference with the company band called “The Bridge.” He enjoyed seeing everyone dancing, laughing, and jamming out to the music and making new friends with coworkers. Tribridge had quickly grown over fifteen years to more than 600 employees with most deployed to customer sites around the U.S. and Canada. The annual conference was a cultural staple designed to re-connect the company with employees and employees with each other. But how much longer could they continue to rely on a once a year event to keep the company together on both social and cultural levels? Chris reflected on a recent executive team meeting where the leaders asked themselves, “How can we keep all of these people, from all over the globe, feeling connected with each other?” The leadership was familiar with and had been discussing ways to keep the company connected through the deployment of an Enterprise Social Network (ESN)--sort of a Facebook for employees. They had been told that an ESN would allow for local employees and remote employees to connect more efficiently to help create an overall cohesive work environment. In theory, it would be a much less expensive approach than flying everyone in to Tampa. And, it was supposed to create a continuous--not just once a year--flow of interactions through an online environment. Plus, wasn’t everyone already familiar with the tool? After all, nearly everyone was on Facebook. Why not set up an ESN and they could join that too? At the same time, the decision to proceed wasn’t easy. There were many factors Milan and the leadership had to consider. Email, Instant Messaging (IM), phone calls and SharePoint were Tribridge’s current forms of communication and connectivity. Would connecting through an ESN replace those platforms? Would it be “in addition to” them? Also, Tribridge was a “Microsoft shop” using Office 365. Office 365 included the ESN platform called Yammer. Would using Yammer be more efficient than email for communication? Would it be as effective as a party for connectivity? Could it share and propagate a culture with a distributed workforce? Since Yammer seemed to be the inevitable choice at Tribridge, maybe the real questions would revolve around how to implement another system in the already busy world that was Tribridge.

Background:Retrospective studies have found that people with elevated social anxiety (SA) show a preference for digital/online communication, which may be due to perceptions of enhanced emotional safety. Whether these preferences for/benefits of digital compared to face-to-face communication manifest in the real world has yet to be explored. Methods: We recruited samples of college students (N = 125) and community adults (N = 303) with varying levels of SA, sampled their emotions during digital and face-to-face communication using ecological momentary assessment (EMA) (Study 1) and a day reconstruction method (DRM) (Study 2), and preregistered our hypotheses (https://osf.io/e4y7x/). Results: Results from both studies showed that SA did not predict the likelihood of engaging in digital compared to face-to-face communication, and SA was associated with less positive and more negative emotions regardless of communication medium. Study 2 also showed that whether digital communication was synchronous (e.g., in real time via phone/video chat) or asynchronous (e.g., texting/instant messaging) did not impact the association between SA and emotions. Limitations: EMA and DRM methods, despite their many advantages, may be suboptimal for assessing the occurrence of digital communication behaviors relative to more objective methods (e.g., passively collecting smartphone communication data). Using event-contingent responding may have also yielded more reports of digital communication, thus strengthening our power to detect small, cross-level interaction effects. Conclusions:These results challenge beliefs that digital/online communication provides a source of emotional safety for people with elevated SA and suggests a greater need to address SA-related emotional impairments across digital communication platforms.

In establish good relationship with customer, companies need to have a good customer relationship management system as well. The purpose of this study is to explore the level of development of the use of instant messaging applications that are used for mobility of companies in establishing relationships with customers; and to investigate the factors considered important for the success of the mobility of companies in establishing relationships with their customers. In this study it was found that not all instant messaging application has a feature which serves to establish rapport with customers. The results showed some of the determinants of success in the utilization of instant messaging applications is the ease of use, target the most used mobile devices, operating systems most used by users, and mobile application user interface that is used.
