Overview

• DHS Secretary Kristi Noem issued a National Terrorism Advisory System bulletin warning of a heightened threat environment through September, citing possible cyberattacks, violent acts, and antisemitic hate crimes
• The advisory highlights the likelihood of low-level intrusions by pro-Iranian hacktivists and potential operations by Iranian government–affiliated cyber units against US networks
• Former FBI investigators warn that both state-sponsored destructive malware attacks and spontaneous lone-wolf violence could target utilities, financial systems, and transportation infrastructure
• US Cyber Command and CISA, guided by former director Jen Easterly, have urged organizations to apply patches, enable phishing-resistant multifactor authentication, and tighten password management
• Officials caution that the Israel-Iran cyberwar may fuel extremist violence in the US, including plots against perceived Jewish, pro-Israel, or government-linked targets
