The Russian state-sponsored hacking group, known as Cozy Bear, attempted to break into foreign embassies by trying to share malware-infected files using Dropbox or Google Drive storage. It is unknown whether these attacks were successful.

Summary

This article by Sam Sabin, writing for Axios, makes the following points:
  • This attack marks an expansion in Russian state hackers' abuse of cloud services.
  • Several embassies in Brazil and Portugal were sent a phishing email disguised as a Dropbox or Google Drive link.
  • The link purported to be to an agenda for an upcoming meeting.
  • If the link were downloaded, it would infect the downloader's computer with malware.
  •  This provided hackers with a backdoor into the recipient's file system.
