The United States’ cybersecurity agency is warning about Russian military hackers exploiting a critical software flaw that makes it possible to weaponize email.

“Russian military cyber actors, publicly known as Sandworm Team, have been exploiting a vulnerability in Exim mail transfer agent (MTA) software since at least last August,” the National Security Agency (NSA) said May 28 in a cybersecurity advisory.
