FBI Cyber Bulletin: IP Addresses and Domains Used by Iran-Based Cyber Actors to Attack Victims Worldwide

The FBI assesses a group of malicious cyber actors—likely located in Iran—use Virtual Private Server infrastructure hosted in the United States to compromise government, corporate, and academic computer networks based in the Middle East, Europe and the United States. This infrastructure is used in conjunction with identified malicious domains to support a broad cyber campaign which likely includes the use of e-mail spear phishing, social engineering, and malicious Web sites (“watering hole attack”). These cyber actors almost certainly have been involved in this activity since at least early-2015.

DHS-FBI Joint Analysis Report on GRIZZLY STEPPE Russian Malicious Cyber Activity

This Joint Analysis Report (JAR) is the result of analytic efforts between the Department of Homeland Security (DHS) and the Federal Bureau of Investigation (FBI). This document provides technical details regarding the tools and infrastructure used by the Russian civilian and military intelligence Services (RIS) to compromise and exploit networks and endpoints associated with the U.S. election, as well as a range of U.S. Government, political, and private sector entities. The U.S. Government is referring to this malicious cyber activity by RIS as GRIZZLY STEPPE.

(U//FOUO) DHS Intelligence Assessment: Damaging Cyber Attacks Possible but Not Likely Against the US Energy Sector

This Assessment establishes a baseline analysis of cyber threats to the US energy sector based on comprehensive FY 2014 incident reporting data compiled by ICS-CERT, as well as reporting by the Intelligence Community (IC), private sector cybersecurity industry, and open source media between early 2011 and January 2016. This Assessment is designed to help close gaps between the private sector’s and the IC’s understanding of current cyber threats facing the US energy sector. Critical infrastructure owners and operators can use this analysis to better understand cyber threats facing the US energy sector and help focus defensive strategies and operations to mitigate these threats. The Assessment does not include an in-depth analysis of foreign cyber doctrines or nation-state red lines for conducting cyber attacks against the United States. The information cutoff date for this Assessment is January 2016.

FBI Warns of Cyber Espionage Targeting the Aviation Industry

Since June, advanced persistent threat (APT) actors have been targeting the aviation industry and attempting to extract confidential information by sending “spear-phishing” emails designed to trick recipients into opening malicious attachments or follow links to infected websites. According to an FBI Cyber Division bulletin from July 8, “individuals associated with the air travel industry” have received an increased number of spear-phishing emails often using spoofed senders “in an attempt to make the e-mail appear more legitimate.”

(U//FOUO) FBI Cyber Division Bulletin: Advanced Persistent Threat (APT) Actors Targeting Aviation Industry

Since June 2013, the FBI has observed advanced persistent threat (APT) actors’ increased interest in the aviation industry. APT actors have sent spear-phishing e-mails targeting individuals associated with the air travel industry. Some of the spear-phishing e-mails originated from a spoofed sender in an attempt to make the e-mail appear more legitimate. E-mail recipients should be aware of suspicious and potentially malicious e-mail attachments or links.
