The US Federal Depository Library Program defaced with Iranian propaganda materials

The hackers defaced the website’s home page with pro-Iran propaganda posters. At the time of this publication, the website has not been restored and is out of reach for the public. A spokesperson for the U.S. Homeland Security Department told the media it remains unclear if this hacking was carried out by the Iranians.

It is worth mentioning that government’s websites are in general less secure than private company websites, and are considered low-class bait for hackers.

Cyber security experts do not categorize these types of attacks as measures targeting the U.S. infrastructure. Despite the fact that an official U.S. government website was hacked, no essential information was stolen. It is also worth noting that the alleged hacking was carried out due to a vulnerability in Drupal CMS.
