There has been substantial commentary on the role of cyberattacks carried out by low-level cybercrime actors in the Russia-Ukraine conflict. We analyse 358k website defacement attacks, 1.7M UDP amplification DDoS attacks, 1764 posts made by 372 users on Hack Forums mentioning the two countries, and 441 Telegram announcements (with 58k replies) of a volunteer hacking group for two months before and four months after the invasion. We find the conflict briefly but notably caught the attention of low-level cybercrime actors, with significant increases in online discussion and both types of attacks targeting Russia and Ukraine. However, there was little evidence of high-profile actions; the role of these players in the ongoing hybrid warfare is minor, and they should be separated from persistent and motivated 'hacktivists' in state-sponsored operations. Their involvement in the conflict appears to have been short-lived and fleeting, with a clear loss of interest in discussing the situation and carrying out both website defacement and DDoS attacks against either Russia or Ukraine after just a few weeks.

Trust and reputation play a core role in underground cybercrime markets, where participants are anonymous and there is little legal recourse for dispute arbitration. These underground markets exist in tension between two opposing forces: the drive to hide incriminating information, and the trust and stability benefits that greater openness yields. Revealing information about transactions to mitigate scams also provides valuable data about the market. We analyse the first dataset, of which we are aware, about the transactions created and completed on a well-known and high-traffic underground marketplace, Hack Forums, along with the associated threads and posts made by its users over two recent years, from June 2018 to June 2020. We use statistical modelling approaches to analyse the economic and social characteristics of the market over three eras, especially its performance as an infrastructure for trust. In the Set-up era, we observe the growth of users making only one transaction, as well as 'power-users' who make many transactions. In the Stable era, we observe a wide range of activities (including large-scale transfers of intermediate currencies such as Amazon Giftcards) which declines slowly from an initial peak. Finally, we analyse the effects of the Covid-19 pandemic, concluding that while we see a significant increase in transactins across all categories, this reflects a stimulus of the market, rather than a transformation. New users overcome the 'cold start' problem by engaging in low-level currency exchanges to prove their trustworthiness. We observe currency exchange accounts for most contracts, and Bitcoin and PayPal are the preferred payment methods by trading values and number of contracts involved. The market is becoming more centralised over time around influential users and threads, with significant changes observed during the Set-up and Covid-19 eras.

Illegal booter services offer denial of service (DoS) attacks for a fee of a few tens of dollars a month. Internationally, police have implemented a range of different types of intervention aimed at those using and offering booter services, including arrests and website takedown. In order to measure the impact of these interventions we look at the usage reports that booters themselves provide and at measurements of reflected UDP DoS attacks, leveraging a five year measurement dataset that has been statistically demonstrated to have very high coverage. We analysed time series data (using a negative binomial regression model) to show that several interventions have had a statistically significant impact on the number of attacks. We show that, while there is no consistent effect of highly-publicised court cases, takedowns of individual booters precede significant, but short-lived, reductions in recorded attack numbers. However, more wide-ranging disruptions have much longer effects. The closure of HackForums' booter market reduced attacks for 13 weeks globally (and for longer in particular countries) and the FBI's coordinated operation in December 2018, which involved both takedowns and arrests, reduced attacks by a third for at least 10 weeks and resulted in lasting change to the structure of the booter market.

Within the Environmental 'omics community Bio-Linux is a widely used tool. This has the advantage of providing in a single deliverable package all necessary software and tools to support common analyses. With the growth in data volumes within the community and increasing constraints on user access and control over their own desktops an alternative delivery method of Bio-Linux and, in future, the Docker container environment is necessary. Within the EOS Cloud project we have constructed a Desktop as a Service system to centrally host virtual machines with these tools preconfigured and maintained. To enable efficient use of the resources we have enabled user controlled resource scaling so that users are able to utilise small scale VMs for task configuration and data manipulation and boost to a larger scale to run analysis applications all the while maintaining the user environment in a consistent manner. Alongside this within the project we have been developed tools to simplify the increasingly popular Docker software usage model. This includes ensure uniformity of behaviour between the host system and the running Docker container. Within the invitation only trial user community we identify two different exemplars groups and explain their usage and how the products and services developed within the project are useful for them. We conclude discussing the useful nature of Desktop as a Service, how it is of great benefit to the bioinformatics community but could also be of great use elsewhere, where the need for a stable user environment with applications already available that do not rely on local ICT support.
