A group claiming to represent the government of Iran has hacked a website operated by the U.S. government

The website operated by the little-known Federal Depository Library Program, fdlp.gov, was hacked and defaced on Saturday, and has been offline.

A message left on the website by the hackers read: 'in the name of god. >>>>> Hacked By Iran Cyber Security Group HackerS ... ;)<<<<<. This is only small part of Iran's cyber ability ! We're always ready.'

The FDLP is a program created to make federal government publications available to the public at no cost. 

The image above appeared on fdlp.gov on Saturday before the website was taken offline

The hackers in their message made reference to the death of Qassem Soleimani, and depicted President Donald Trump being beaten by a fist with the Revolutionary Guard insignia

Current Google results show the defaced page title text of the fdlp.gov website
