(U//FOUO) DHS-FBI-NCTC Bulletin: Terrorists Call for Attacks on Hospitals, Healthcare Facilities

Recent calls over the past year for attacks on hospitals in the West by media outlets sympathetic to the Islamic State of Iraq and ash-Sham (ISIS) highlight terrorists’ perception of hospitals as viable targets for attack. Targeting hospitals and healthcare facilities is consistent with ISIS’s tactics in Iraq and Syria, its previous calls for attacks on hospitals in the West, and the group’s calls for attacks in the West using “all available means.” While we have not seen any specific, credible threat against hospitals and healthcare facilities in the United States, we remain concerned that calls for such attacks may resonate with some violent extremists and lone offenders in the Homeland because of their likely perceived vulnerabilities and value as targets.

(U//FOUO) DHS-FBI Intelligence Assessment: Baseline Comparison of US and Foreign Anarchist Extremist Movements

This joint DHS and FBI Assessment examines the possible reasons why anarchist extremist attacks in certain countries abroad and in the United States differ in the frequency of incidents and degree of lethality employed in order to determine ways US anarchist extremists actions might become more lethal in the future. This Assessment is intended to establish a baseline comparison of the US and foreign anarchist extremist movements and create new lines of research; follow-on assessments will update the findings identified in the paper, to include the breadth of data after the end of the reporting period (as warranted by new information), and identify new areas for DHS and FBI collaboration on the topic. This Assessment is also produced in anticipation of a heightened threat of anarchist extremist violence in 2016 related to the upcoming Democratic and Republican National Conventions—events historically associated with violence from the movement.

(U//FOUO) DHS Intelligence Note: Germany Christmas Market Attack Underscores Threat to Mass Gatherings and Open-Access Venues

A 25-ton commercial truck transporting steel beams from Poland to Germany plowed into crowds at a Christmas market in Berlin at about 2000 local time on 19 December, killing at least 12 people and injuring 48 others, several critically, according to media reporting citing public security officials involved in the investigation. The truck was reportedly traveling at approximately 40 miles per hour when it rammed the Christmas market stands. Police estimate the vehicle traveled 80 yards into the Christmas market before coming to a halt.

(U//FOUO) DHS, Fusion Centers Reference Aid: Malicious Terrorism Hoaxes Likely to Endure, Strain State and Local First Responder Resources

This Reference Aid is intended to provide information on malicious terrorism hoaxes that will continue to challenge first responder resources throughout the Homeland and territories. This Reference Aid is provided by I&A, DIAC, NCRIC, NVRIC, and NJ-ROIC to support their respective activities, to provide situational awareness, and to assist federal, state, local, tribal, and territorial government counterterrorism and law enforcement officials and first responders with recognizing the indicators and implications of malicious terrorism hoaxes. The use of hoax calls may also be used as a technique to lure authorities to a particular location for the purpose of conducting a potential attack, but is not discussed in this article, as luring is viewed as its own distinct tactic.

(U//FOUO) DHS Assessment: Cyber Threats and Vulnerabilities to US Election Infrastructure

DHS has no indication that adversaries or criminals are planning cyber operations against US election infrastructure that would change the outcome of the coming US election. Multiple checks and redundancies in US election infrastructure—including diversity of systems, non-Internet connected voting machines, pre-election testing, and processes for media, campaign, and election officials to check, audit, and validate results—make it likely that cyber manipulation of US election systems intended to change the outcome of a national election would be detected.

DHS US-CERT Understanding Distributed-Denial-of-Service Attacks

One of the most significant cyber threats to businesses, local and federal government agencies is the Distributed-Denial-of-Service attack (DDoS). A Distributed Denial of Service attack (DDoS) occurs when an attacker commands a number of computers to send numerous requests to a target computer. The overwhelming flood of requests to the website or computer network can cause it to shut down or fail to handle the requests of legitimate users, much like a rush hour traffic jam on the freeway. This type of attack can completely disrupt an organization’s operations until the network is able to be restored. Understanding the basic concept and methods of a DDoS attack can help operators of both large and small networks mitigate the severity of the attack.

DHS San Francisco Earthquake Study Hayward Fault Magnitude 7.0 Scenario

The results of this analysis show a strong earthquake will likely cause significant damage to critical infrastructure in the area affecting 547 dams or water control structures, render approximately 300 roadway segments unusable, and cause damage to 172 water and wastewater treatment systems. The scenario earthquake will likely cause damage to 154 dams in the area. Seven of the dams will likely experience Extensive or Complete damage. The Ward Creek Dam, which is used for flood control, is likely to incur Complete damage. Extensive damage to the James H. Turner Dam poses the greatest risk to downstream population. The earthquake will cause damages to many road segments, bridges, and tunnels in the area. As a result, travel times on these roadways and others will increase significantly. Multiple areas on freeways such as I–680, I–880, and I–580 will have the highest above normal traffic volumes. Several bridges on these freeways will also likely incur Extensive damage. Tunnels in the area will likely have less damage with bores in the Caldecott Tunnel on State Route 24 experiencing only Moderate damage.

Feds Say Homegrown Terrorists Increasingly Prioritizing Civilian Targets

A joint intelligence bulletin issued in late August by the Department of Homeland Security, FBI, and National Counterterrorism Center (NCTC) assesses that homegrown violent extremists (HVEs) are “increasingly favoring civilian targets” as opposed to government facilities and personnel. Previous assessments have found that HVEs are most likely to prioritize “law enforcement personnel, military members, and US Government-associated targets.” However, a recent shift towards civilian targets has likely been driven by the accessibility of “soft targets” that are less secure and provide greater opportunities for mass casualty attacks.

(U//FOUO) DHS-FBI-NCTC Bulletin: Homegrown Violent Extremists Focusing More on Civilian Targets

This Joint Intelligence Bulletin (JIB) is intended to provide new insight into the targeting preferences of some homegrown violent extremists (HVEs) and to examine detection challenges and opportunities.

Joint Staff Strategic Assessment: Counter-Da’esh Influence Operations Cognitive Space Narrative Simulation Insights

When planning to deal with any adversary or potential adversaries, it is essential to understand who they are, how they function, their strengths and vulnerabilities, and why they oppose us. Events over the course of the last year and a half highlight the importance of those factors as they relate to the Islamic State of Iraq and the Levant (ISIL or Da’esh). One of Da’esh’s obvious strengths is its ability to propagate tailored messages that resonate with its audiences. If the US Government and our allies are to counter Da’esh effectively, we must attack this center of gravity.

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.

DHS Infrastructure Report: Consequences of Malicious Cyber Activity Against Seaports

Unless cyber vulnerabilities are addressed, they will pose a significant risk to port facilities and aboard vessels within the Maritime Subsector. These potential vulnerabilities include limited cybersecurity training and preparedness, errors in software, inadequately protected commercial off-the-shelf technologies and legacy systems, network connectivity and interdependencies, software similarities, foreign dependencies, global positioning system jamming-spoofing, and insider threats.

DHS Report Details “Persistent” Cyber Targeting of Police, Emergency Services

Cyber attacks against law enforcement, fire departments and other emergency services have become increasingly common and are likely to increase according to a recent intelligence assessment prepared by the Department of Homeland Security and the Multi-State Information Sharing and Analysis Center (MS-ISAC). The assessment, which was distributed to law enforcement in September 2015 and was obtained by Public Intelligence, reviewed a number of “cyber attacks against the [emergency services sector or ESS] between February 2012 and May 2015,” finding that “targeting of the ESS will likely increase as ESS systems and networks become more interconnected and the ESS becomes more dependent on information technology for the conduct of daily operations—creating a wider array of attack vectors for cyber targeting.”

(U//FOUO) DHS Assessment: Cyber Targeting of the US Emergency Services Sector Limited, But Persistent

Cyber targeting of the ESS will likely increase as ESS systems and networks become more interconnected and the ESS becomes more dependent on information technology for the conduct of daily operations—creating a wider array of attack vectors for cyber targeting. Independent researchers have already reported on the widespread availability of vulnerabilities and attack vectors for critical hardware and software that is used in this sector extensively. Such vulnerable systems include call-center communications-management software, closed-circuit TV camera systems, interactive voice response systems, and emergency alert systems—particularly wireless emergency alert systems.
