A group claiming to be hackers from Iran breached a federal website on Saturday and posted messages vowing revenge for Washington’s killing of top military commander Qassem Suleimani.
Hackers replaced the Federal Depository Library Program program’s website late Saturday with a page titled “Iranian Hackers!” that displayed images of Iran’s supreme leader Ayatollah Ali Khamenei, the Iranian flag and an image depicting a bloodied President Donald Trump being punched in the face.
“Martyrdom was (Suleimani’s)… reward for years of implacable efforts,” read a graphic depicting US president Donald Trump being punched by a fist emanating from Iran as missiles fly by.
“With his departure and with God’s power, his work and path will not cease and severe revenge awaits those criminals who have tainted their filthy hands with his blood and blood of the other martyrs,” it said.
“This is only small part of Iran’s cyber ability !” another caption on the page read in white text on a black background.
The images appeared on the little-known US government agency’s website before the site was taken offline. The Cybersecurity and Infrastructure Security Agency, a division of the Department of Homeland Security, said it was monitoring the situation.
“We are aware the website of the Federal Depository Library Program was defaced with pro-Iranian, anti-US messaging,” the cybersecurity agency said in a statement. “At this time, there is no confirmation that this was the action of Iranian state-sponsored actors. The website was taken offline and is no longer accessible.”
The statement added that “in these times of increased threats” all organizations should increase cyber monitoring, back up IT systems, implement secure authentication and have an incident response plan ready should a hack take place.
DHS issued a two-week National Terrorism System advisory noting the U.S. drone strike in Iraq last week that killed Iran commander Qassem Soleimani. That led Iran and several affiliated extremist organizations to publicly state they intend to retaliate against the United States.
“Iran maintains a robust cyber program and can execute cyber attacks against the United States,” DHS warned. “Iran is capable, at a minimum, of carrying out attacks with temporary disruptive effects against critical infrastructure in the United States.”
