The FBI, the UK's NCSC and the Dutch AIVD have issued a joint advisory on HEAVYGRAM, Windows spyware that operates without a command-and-control server.

Infection begins with a single malicious file sent in a message, and security experts are urging Windows users to be cautious with unexpected attachments.
