The paper did not reveal details of the cyber campaign, but said it did not target any part of Iran’s missile or other defense programs. Its mission was to degrade the covert strike capabilities of the IRGC, which operates in a paramilitary capacity and is not supervised by the military. Washington blamed the IRGC for the limpet mine attacks against oil tankers, and expressed concerns that they would continue. The cyber attack corrupted the computer databases and communications networks that the IRGC uses to co-ordinate covert operations at sea, and resulted in the temporary cessation of IRGC attacks on oil tankers, said The Times.

The June 20 cyber attacks were not meant to be permanent but their effects have endured much longer than was expected, according to the paper. It cited claims by anonymous senior American officials that the IRGC is “still trying to repair critical communications systems and has not recovered the data lost in the attack”. It is also worth noting that, according to US sources, Iran did not escalate its own cyber attacks against Western targets in retaliation to the American cyber campaign against the IRGC.

However, according to The Times, some American officials have expressed doubts about the wisdom and long-term impact of the cyber operation. They claim that the cyber attack gave the Iranians the opportunity to collect valuable information about US cyber capabilities. It also allowed them to detect and fix their vulnerabilities so that they are now better able to defend against future cyber attacks. Lastly, the attacks neutralized IRGC communications networks, which the US had penetrated and was collecting vital intelligence from, they argue.
