The FBI and the U.S. Cybersecurity and Infrastructure Security Agency (CISA) have issued a new joint advisory on a gas pipeline intrusion campaign allegedly conducted by Chinese state-sponsored hackers between 2011 and 2013. In addition, CISA has updated five advisories released between 2012 and 2017 to attribute malware and malicious activity to various nation states.

The new advisory describes a spear-phishing and intrusion campaign carried out between December 2011 and 2013 by Chinese hackers against oil and natural gas pipeline companies in the United States.
