National Governors Association Brief: Enhancing Role of Fusion Centers in Cybersecurity

NGA-FusionCentersCyber

In recent years, the growing number and sophistication of threats to the nation’s cyber infrastructure have motivated governors to consider adding or expanding cybersecurity capabilities within state fusion centers. Through fusion centers, states receive classified and unclassified information and intelligence from multiple sources across the nation and combine or “fuse” that information into “products” (for example, law enforcement notices and warnings) that help improve state and national readiness to respond to an attack or threat. Since their inception, fusion centers have become more sophisticated, uniform, and nationally networked. As they have matured and evolved, so have their missions. Originally designed to focus on terrorism, they now address a wider array of threats and hazards, including “accidents; technological events; natural disasters; warfare; and chemical, biological (including pandemic influenza), radiological, nuclear, or explosive events.”

UK Computer Emergency Response Team (CERT) Introduction to Social Engineering

UK-CERT-SocialEngineering

Social engineering is one of the most prolific and effective means of gaining access to secure systems and obtaining sensitive information, yet requires minimal technical knowledge. Attacks vary from bulk phishing emails with little sophistication through to highly targeted, multi-layered attacks which use a range of social engineering techniques. Social engineering works by manipulating normal human behavioural traits and as such there are only limited technical solutions to guard against it.

DHS NCCIC Report on Assessing Risks of Your Digital Footprint

NCCIC-DigitalFootprint

To facilitate efficiency and effectiveness on a global scale, massive amounts of data are stored and processed in systems comprised of hardware and software. Each digital transaction or interaction we make creates a digital footprint of our lives. Too often, we don’t take the time to assess not only the size of our digital footprint, but what risks are involved in some of the choices we make. Our data lives in our social media profiles, mobile devices, payment accounts, health records, and employer databases among other places. The loss or compromise of that data can result in an array of impacts from identity theft to financial penalties, fines, and even consumer loyalty and confidence. This results in both a shared risk and therefore shared responsibility for individuals, businesses, organizations and governments. The following product is intended to facilitate awareness of one’s digital footprint as well as offer suggestions for a unified approach to securing that data. This is not an all-encompassing product, but rather offers discussion points for all that hold a stake in the security of our data.

FBI Alert: Iranian Cyber Actors Targeting Defense Contractors, Schools and Energy Sector

FBI-IranianHacking

A group of cyber actors utilizing infrastructure located in Iran have been conducting computer network exploitation activity against public and private U.S. organizations, including Cleared Defense Contractors (CDCs), academic institutions, and energy sector companies. The actors typically utilize common computer intrusion techniques such as the use of TOR, open source reconnaissance, exploitation via SQL injection and web shells, and open source tools for further network penetration and persistence. Internet-facing infrastructures, such as web servers, are typical targets for this group. Once the actors penetrate a victim network, the actors exfiltrate network design information and legitimate user credentials for the victim network. Often times, the actors are able to harvest administrative user credentials and use the credentials to move laterally through a network.

DHS National Cybersecurity and Communications Integration Center: Suspicious “Invoic” Email Sent to Government Personnel

NCCIC-SuspiciousEmails

On 15 October 2014, a phishing email was dispersed to a wide variety of government employees. NCCIC has also received a number of reports indicating that members within the Education Sector and Financial Sector; International, State, Local, and Tribal organizations have also received similar email messages. The email suggested that the recipient had an unpaid debt and the attachment was an invoice showing the debt information. The subject line reads “UNPAID INVOIC” and the content simply instructs recipients to open the attachment which is a PDF file that is believed to be malicious. Rather than installing malware files from the PDF file itself, it appears to use embedded JavaScript within the file to redirect victims to a malicious website where additional malware can be installed.

Destructive malware used by unknown computer network exploitation (CNE) operators has been identified. This malware has the capability to overwrite a victim host’s master boot record (MBR) and all data files. The overwriting of the data files will make it extremely difficult and costly, if not impossible, to recover the data using standard forensic methods. Analysis of this malware is presented to provide the computer network defense (CND) community with indicators of this malware.

NIST Special Publication 800-150: Guide to Cyber Threat Information Sharing Draft

NIST-CyberThreatSharing

As the magnitude and complexity of cyberspace increases, so too does the threat1 landscape. Cyber attacks have increased in both frequency and sophistication resulting in significant challenges to organizations that must defend their infrastructure from attacks by capable adversaries. These adversaries range from individual attackers to well-resourced groups operating as part of a criminal enterprise or on behalf of a nation-state. These adversaries are persistent, motivated, and agile; and employ a variety of tactics, techniques, and procedures (TTPs) to compromise systems, disrupt services, commit financial fraud, expose sensitive information, and steal intellectual property. To enhance incident response actions and bolster cyber defenses, organizations must harness the collective wisdom of peer organizations through information sharing and coordinated incident response. This publication expands upon the guidance introduced in Section 4, Coordination and Information Sharing of NIST Special Publication (SP) 800-61, Computer Security Incident Handling Guide and explores information sharing, coordination, and collaboration as part of the incident response life cycle.

FBI Warns of Hacktivist Threats Following U.S. Airstrikes in Iraq and Syria

A twitter account

The FBI Cyber Division has issued a notification to private industry and law enforcement to be aware of the potential for retaliatory cyber attacks following recent U.S. military actions in the Middle East. While the FBI has “no information at this time to indicate specific cyber threats to US networks or infrastructure in response to ongoing US military air strikes against the terrorist group known as the Islamic State of Iraq and the Levant (ISIL)” the bulletin states that the FBI believes that “extremist hackers and hacktivist groups, including but not limited to those aligned with the ISIL ideology, will continue to threaten and may attempt offensive cyber actions against the United States in response to perceived or actual US military operations in Iraq or Syria.”

(U//FOUO) FBI Bulletin: Threat of Cyberterrorist and Hacktivist Activity in Response to U.S. Military Actions in the Middle East

FBI-ISIL-Cyberterrorism

The FBI has no information at this time to indicate specific cyber threats to US networks or infrastructure in response to ongoing US military air strikes against the terrorist group known as the Islamic State of Iraq and the Levant (ISIL), also known as the Islamic State of Iraq and al-Shams (ISIS) or the Islamic State (IS). However, the FBI assesses extremist hackers and hacktivist groups, including but not limited to those aligned with the ISIL ideology, will continue to threaten and may attempt offensive cyber actions against the United States in response to perceived or actual US military operations in Iraq or Syria. The FBI bases this assessment on recent, nonspecific, and probably aspirational threats made on social media platforms to carry out cyber as well as physical attacks in response to the US military presence in the Middle East.
