Iran likely intends to target the control systems U.S. energy companies use to monitor their storage tanks, potentially resulting in physical damage or the spilling of fuel or chemicals, according to an intelligence bulletin reviewed by ABC News.

The bulletin issued by the Department of Homeland Security said that in early August, Iranian cyber actors used DeepSeek AI to research the capacity of U.S.-based storage tanks, "likely as part of targeting research against the industrial control systems of a U.S. energy entity operating oil wells."

If a hacker compromises automated gauges on an oil storage tank, the hacker could trigger false alarms or prevent alerts indicating a tank is empty, the bulletin said.

Worse, the hacker could "initiate pump shutoff," potentially disrupting service; or change temperature values that "could prevent alerts notifying that the contents of the tank are overheating," according to the bulletin.

"If a large number of [automated tank gauges] were compromised in a specific area, an attacker could change tank values to show tanks as almost empty, leading to an unnecessary dispatch of fuel tankers; show tanks as full even when nearly empty, leading to service outages at gas stations," the bulletin said.

DHS said the information is deemed "credible and actionable" though "not considered finished intelligence."

The goal is to inform U.S. energy companies and law enforcement agencies about what Iran is likely planning so they can take defensive measures.

Houthi military spokesperson Yahya Saree on Wednesday claimed that the Iran-backed group launched a fresh missile and drone attack on oil facilities operated by Aramco -- Saudi Arabia's state-owned petroleum and natural gas company -- in the Red Sea port city of Yanbu.

Houthi ballistic missiles also targeted the King Khalid Air Base in the city of Khamis Mushait, in southwestern Saudi Arabia, Saree said.

The Saudi Defense Ministry did not immediately comment on Saree's claims.

The State Department on Tuesday reissued its level 3 travel warning for Saudi Arabia, telling Americans to "reconsider travel to Saudi Arabia due to risk of Iranian drone and missile targeting of American interests, armed conflict, terrorism, exit bans and local laws regarding social media activity."

"Some areas have increased risk," the alert said, noting a level 4 warning for border areas with Yemen, "Do not travel to the Yemen border due to threat of terrorism," the alert said.

The Republican-led House adopted a resolution to curb President Donald Trump’s Iran war powers by a vote of 220-204 late Tuesday -- dealing a significant blow to the administration for the third time since the start of the conflict.

Seven Republicans -- Reps. Thomas Massie of Kentucky, Brian Fitzpatrick of Pennsylvania, Warren Davidson of Ohio, Tom Barrett of Michigan, Nancy Mace of South Carolina, Mariannette Miller-Meeks of Iowa and Zach Nunn of Iowa -- voted in favor of the resolution along with all Democrats present.

The last time the House adopted a similar resolution with bipartisan support was on July 23, when only four Republicans backed the effort. Notably, two Iowa Republicans voted to withdraw U.S. military forces in Iran.

The concurrent resolution, led by Rep. Seth Moulton, D-Mass., calls on the president to terminate the use of U.S. armed forces in hostilities against Iran. The resolution, which is symbolic in nature and expresses the sentiment of the House, now heads to the Senate for consideration. Even if the upper chamber follows suit, a concurrent resolution does not carry the weight of law and is not subject to veto or presented to the president.

This is the sixth time the House has taken up a Democratic-led Iran war powers resolution in recent months.
