Iranian Hackers Have Been ‘Password-Spraying’ the US Grid

A state-sponsored group called Magnallium has been probing American electric utilities for the past year.

In the wake of the US assassination of Iranian general Qasem Soleimani and the retaliatory missile strike that followed, Iran-watchers have warned that the country could deploy cyberattacks as well, perhaps even targeting US critical infrastructure like the electric grid. A new report lends some fresh details to the nature of that threat: By all appearances, Iranian hackers don’t currently have the capability to start causing blackouts in the US. But they’ve been working to gain access to American electric utilities, long before tensions between the two countries came to a head.

On Thursday morning, industrial control system security firm Dragos detailed newly revealed hacking activity that it has tracked and attributed to a group of state-sponsored hackers it calls Magnallium. The same group is also known as APT33, Refined Kitten, or Elfin, and has previously been linked to Iran. Dragos says it has observed Magnallium carrying out a broad campaign of so-called password-spraying attacks, which guess a set of common passwords for hundreds of even thousands of different accounts, targeting US electric utilities as well as oil and gas firms.
