Malware utilised in a crippling cyberattacks from an Iranian metal crops final week is connected to an attack that shut down the country’s rail method previous calendar year. In both of those circumstances, on malware strain was used to impact bodily and critical infrastructure, in accordance to a report from Check Level Analysis.

The overlaps in the code, put together with contextual clues and even recycled jokes, show that the very same threat actor, dubbed Indra, is powering the attacks impacting Iran’s infrastructure.
