This time STRATCOMCOE has joined forces with the European Centre of Excellence for Countering Hybrid Threats in producing the report.
"This paper aims to improve the ability of practitioners to collect and analyse evidence in support of the attribution process. It reviews existing approaches to attribution and suggests that malicious activities online can be analysed using four key lenses and three key types of evidence, with differing degrees of accessibility. The paper then looks at how this framework relates to real world cases of investigation conducted by leading practitioners in the field," says a description of the content.
