Microsoft has published the results of its research on systems used to send millions of emails, which distribute at least seven different types of malware.
The tech giant has identified two elements of the new email infrastructure it discovered in March and April 2020, which it followed for the rest of the year. The first section of infrastructure calls it StrangeU because he often uses the word “strange” in news domains. It second part uses a domain creation algorithm – a technique for randomly generating domain names – and so it was named RandomU.
