US on High Alert to Face Iran's Cyber Attacks, Cybersecurity Expert Warns of Danger

Jakarta, CNBC Indonesia - The United States (US) is urged to prepare for cyber attacks from Iran. The targets of such attacks range from businesses to local infrastructure.

The warning was issued following another weekend of attacks by the US and Israel on Iran. Iran has retaliated with strikes hitting a US base, the embassy, and several areas in Tel Aviv, Doha, and Dubai.

Moreover, Iran is also expected to launch cyber attacks which are anticipated to be considerably more dangerous. The country is waiting for the moment to launch such attacks.

“In terms of timing, this is the last chance. In this regard, the danger is much greater,” said Pavel Gurvich, founder and CEO of the cybersecurity startup Tenzai, quoted by CNBC International, Thursday (5/3/2026).

Meanwhile, US Secretary of Homeland Security Kristi Noem spoke about national security this week. She confirmed that the Department of Homeland Security (DHS) has been collaborating with intelligence partners and federal law enforcement to monitor and thwart each potential threat carefully.

This threat of cyber attacks arises as the Cybersecurity and Infrastructure Security Agency (CISA) faces a range of issues from partial government shutdowns, forced leave, and management shake-ups.

CISA is recorded to have lost a third of its staff since Donald Trump resumed the presidency. The agency also has to contend with many employees leaving their posts.

One of them, the agency’s acting director, Madhu Gottumukkala, who was moved to another division last week. The head of information technology, Bob Costello, announced his resignation from federal service via a LinkedIn post.

The CISA website has been inactive since 17 February 2026. The site states the reason as funding from the federal government having been halted.

On the same date, DHS announced that CISA would cancel cybersecurity assessment programs, training and other activities.
