U.S. and Allies Warn of Iranian Cyberattacks on Critical Infrastructure in Year-Long Campaign

Cybersecurity and intelligence agencies from Australia, Canada, and the U.S. have warned about a year-long campaign undertaken by Iranian cyber actors to infiltrate critical infrastructure organizations via brute-force attacks.

“Since October 2023, Iranian actors have used brute force and password spraying to compromise user accounts and obtain access to organizations in the healthcare and public health (HPH), government, information technology, engineering, and energy sectors,” the agencies said in a joint advisory.
