Tehran’s cyber operatives have sought to sow fear and extract intelligence in a series of attacks on Israel and the US

As missile sirens wailed over Israel earlier this month, thousands of Israelis received texts claiming to be from their military, encouraging them to download a fake shelter app, which could have stolen reams of personal data.

The messages, cyber security experts say, are the most visible end of a vast war being waged in the far reaches of the internet between Iran, Israel and the US, and their online sympathisers.

They may use keyboards instead of rifles but Iran’s hackers, who have fought Israel in the digital shadows for years, are among the most battle-hardened soldiers Tehran can call on.
