Escalating Conflict with Iran Raises Fears of Retaliatory Cyberattacks

As tensions between the US, Israel, and Iran continue to escalate, cybersecurity experts warn that the likelihood of Iranian cyberattacks against critical infrastructure in the US has increased. Iran has a history of targeting sectors such as water, energy, finance, and healthcare, and experts believe that the country’s conventional military options are limited, making cyber warfare a more viable choice.

Iran’s Cyber Capabilities

Denis Calderone, chief technology officer at Suzu Labs, notes that organizations in these sectors should be on high alert and actively searching for signs of pre-positioned access in their systems.

“With conventional military options largely off the table, cyber is Iran’s primary asymmetric weapon right now,” he said.

One group of particular concern is APT34, also known as OilRig, Earth Simnavaz, and Helix Kitten, which has been active since 2012 and targets critical industries such as finance, energy, and government agencies. Calderone notes that the group’s recent silence may indicate pre-positioning rather than inactivity.

Types of Cyberattacks

Experts also point out that while DDoS attacks are a concern, the more significant danger lies in wiper malware and the exploitation of internet-accessible industrial control systems. Damon Small, a board member at Xcape, Inc., notes that reports of internet utilization dropping to 4% in Iran were likely the result of a government-imposed “kill switch” aimed at protecting the regime’s digital infrastructure.

Matthew Andriani, chief executive officer at MazeBolt, adds that DDoS is now a frontline tool in regional conflict, but it cuts both ways.

“US, Israel, and Israel-linked organizations are equally exposed to retaliatory high-volume and application-layer attacks during periods of heightened tension,” he said.

Preparing for Cyberattacks

“Our threat analytics suggest that the presumed Iranian actors were mapping regional infrastructure vulnerabilities,” he said.

Randolph Barr, chief information security officer at Cequence Security, points out that Iran has historically demonstrated a strong capability in cyber operations, often leveraging credential theft, social engineering, and access via federated identity systems. He recommends that security teams review federation controls and third-party integrations, implement continuous session validation, and simulate geopolitical threat scenarios to prepare for potential attacks.
