Last October the United States Computer Emergency Readiness Team (US-CERT) published a technical alert on advanced persistent threat (APT) activity targeting energy and other critical infrastructure sectors. Recently, it was updated with new information uncovered since the original report, and there are some interesting revelations this time around.
Since the initial alert, The Department of Homeland Security (DHS) and the Federal Bureau of Investigation (FBI), working with U.S. and international partners, determined that attacks were already underway and being carried out by unspecified threat actors. The new report contains indicators of compromise (IOCs) and technical details on the tactics, techniques, and procedures (TTPs) used by APT actors on compromised victims’ networks.
