From now on, with the help of a translator, we were in direct e-mail contact with Sergei, and he thought we were a Russian in Cologne. We agreed that when the goods arrived we would send them by bus to Tallinn (Estonia), and in return we would keep a notebook of our choice from the consignment. And in fact shortly after our e-mail to Sergei, another fraudulent order arrived at the office of our client in Berlin, and 4 notebooks were delivered to our address in Cologne.
Further investigations (e.g. in Tallinn) then led to the identification of the group of hackers from Ukraine who were responsible for the orders.
It is still not clear whether and how those responsible for the fraud will be brought to justice in their home countries in terms of criminal proceedings, but we managed conclusively to halt the attacks on our client's server system, thus preventing any further damage.
