(U//FOUO) DHS Intelligence Note: Unknown Cyber Actors Target US Water and Sewage Authority Network

An unidentified actor or actors between November 2016 and January 2017 targeted a US water and sewage authority’s network, resulting in excessive cellular charges and unusual traffic on ports 10000 and 9600, according to an FBI source with excellent access who spoke in confidence but whose reliability cannot be determined. The FBI source indicated that four of the seven devices on the authority’s cellular data plan were impacted with high data usage, which was likely a result of compromised network devices. The November 2016–December 2016 billing cycle totaled $45,000, and the December 2016–January 2017 billing cycle totaled $53,000.

DHS NCCIC Report on the Art of Social Engineering

Social engineering, an age old threat, continues to play a significant role in successful attacks against people, enterprises, and agencies. The advent of the Internet, its diverse and increased use, and the reliance on it by almost every element of society, amplifies social engineering opportunities. Cybercriminals enjoy an expansive attack surface, novel attack vectors, and an increasing number of vulnerable points of entry. Threat actors, both cyber and physical, continue to leverage social engineering due in part to its high rate of success. Security experts believe complex social engineering threats will continue across all vectors and attack levels will continue to intensify.

DHS NCCIC Report on Assessing Risks of Your Digital Footprint

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.

DHS National Cybersecurity and Communications Integration Center Bulletin: Hotel Business Centers Keyloggers

The following is an advisory for owners, managers and stakeholders in the hospitality industry, which highlights recent data breaches uncovered by the United States Secret Service (USSS). The attacks were not sophisticated, requiring little technical skill, and did not involve the exploit of vulnerabilities in browsers, operating systems or other software. The malicious actors were able to utilize a low-cost, high impact strategy to access a physical system, stealing sensitive data from hotels and subsequently their guest’s information. The NCCIC and the USSS have provided some recommendations at the end of this document that may help prevent similar attacks on publicly available computers.

DHS National Cybersecurity and Communications Integration Center Heartbleed Advisories

Security researchers from Google Security recently discovered a vulnerability with the Heartbeat extension (RFC6520) to OpenSSL’s Transport Layer Security (TLS) and the Datagram Transport Layer Security (DTLS) protocols. According to open source reports, the vulnerability has existed within certain OpenSSL frameworks since at least 2012. The Heartbeat extension is functionally a “keep-alive” between end-users and the secure server. It works by sending periodic “data pulses” of 64KB in size to the secure server and once the server receives that data; it reciprocates by re-sending the same data at the same size. The out-of-bounds “read” vulnerability exists because the Heartbeat extension in OpenSSL versions 1.0.1 through and 1.0.2-beta (including 1.0.1f and 1.0.2-beta1) do not properly validate the data being sent from the end-user. As a result, a malicious actor could send a specially-crafted heartbeat request to the vulnerable server and obtain sensitive information stored in memory on the server. Furthermore, even though each heartbeat only allows requests to have a data size limited to 64KB segments, it is possible to send repeated requests to retrieve more 64KB segments, which could include encryption keys used for certificates, passwords, usernames, and even sensitive content that were stored at the time. An attacker could harvest enough data from the 64KB segments to piece together larger groupings of information which could help an attacker develop a broader understanding of the information being acquired.

DHS National Cybersecurity and Communications Integration Center Bulletin: Destructive Malware

As related to malware which may exhibit a potentially destructive capability, organizations should increase vigilance and evaluate their capabilities encompassing planning, preparation, detection, and response for such an event. Destructive malware presents a direct threat to an organization’s daily operations, directly impacting the availability of critical assets and data. In addition, the response required for such an event can be extremely resource intensive.

DHS National Cybersecurity and Communications Integration Center Bulletin: Cryptolocker Ransomware

The following product is a coordinated effort between NCCIC, U.S. Secret Service and The Cyber Intelligence Network (CIN), provided to assist in prevention, detection and mitigation of a new ransomeware campaign. Ransomware is malware that restricts access to infected computers and requires victims to pay a ransom in order to regain full access. Cryptolocker is particularly interesting in that it functions by encrypting victims computer files with a combination of RSA-2048 and AES-256 encryption. Once encrypted, victims are provided a window of time in which they can pay the actors to receive the key needed to decrypt their files.

DHS Report: Criminals and Hacktivists May Use 2012 Summer Olympics as Platform for Cyberattacks

Scams, malware campaigns and attacks will continue to grow in scale and complexity as the 27 July opening ceremony in London draws near. Event organizers, sponsors and British authorities continue to increase their physical and cybersecurity awareness as the event approaches. Information systems supporting the Games, transport infrastructure, law enforcement communications, financial operations and similar will become prime targets for criminals. A collective of approximately eighty-seven UK banks exercised their ability to withstand cyber attacks last November. Olympic organizers anticipated cyber threats and began testing their cybersecurity posture during ‘technical rehearsals’ by running scenarios from their Technology Operations Center (TOC) situated on Canary Wharf. The TOC will be manned with over one hundred personnel continuously monitoring critical applications, such as the Commentator Information System, organizers’ intranet, and a telecom infrastructure encompassing 900 servers, 1,000 network and security devices, and 9,500 computers. In addition, British law enforcement organizations have been collaborating with the U.S. Secret Service and other industry experts to understand attack vectors, detection methods and mitigation strategies to combat the threat. However, the cyber implications are more expansive than localized attacks against systems and encompass globally distributed Olympic-themed malware, spam campaigns and scams.

(U//FOUO) DHS Wireless Medical Devices/Healthcare Cyberattacks Report

The expanded use of wireless technology on the enterprise network of medical facilities and the wireless utilization of MDs opens up both new opportunities and new vulnerabilities to patients and medical facilities. Since wireless MDs are now connected to Medical information technology (IT) networks, IT networks are now remotely accessible through the MD. This may be a desirable development, but the communications security of MDs to protect against theft of medical information and malicious intrusion is now becoming a major concern. In addition, many HPH organizations are leveraging mobile technologies to enhance operations. The storage capacity, fast computing speeds, ease of use, and portability render mobile devices an optimal solution.

(U//FOUO) DHS Bulletin: Anonymous Hacktivist Threat to Industrial Control Systems (ICS)

The loosely organized hacking collective known as Anonymous has recently expressed an interest in targeting industrial control systems (ICS). This product characterizes Anonymous’ capabilities and intent in this area, based on expert input from DHS’s Control Systems Security Program/Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) in coordination with the other NCCIC components.

(U//FOUO) DHS Bulletin: “Anonymous” and Associated Hacker Groups Deploying New Cyber Attack Tools

The hacker collective known as ‘Anonymous’ has successfully attacked a wide range of public and private sector entities since 2003 with relatively crude tools. Historically, they rely on tools such as the Low Orbit Ion Cannon (LOIC) or Botnets to deny access to websites, or hijack or deface web pages and post quasi-political statements, or perform other malicious activity. Since many of these older tools made it relatively easy for law enforcement and other government forces to identify the source of an attack and then arrest the perpetrator, Anonymous members may have recognized a need to have more advanced tools that offered a lesser degree of exposure. They recently claimed to have developed and possibly employed several new cyber attack tools for use in their self-proclaimed ‘internet civil disobedience’ campaigns. The NCCIC, coordinating with several of its partners, believes there are at least four new tools being shared among and employed by Anonymous members: #RefRef, Apache Killer, Anonware, and Universal Rapid Gamma Emitter (URGE).

DHS Cybersecurity Bulletin: Physical Events Provide Phishing/Social Engineering Opportunities

Malicious users seeking to exploit interest related to physical events such as earthquakes and hurricanes will likely use subject lines and attachment titles related to the incidents in phishing e-mails. Network administrators and general users should be aware of these attempts and avoid opening messages with attachments and/or subject lines related to physical events.

DHS Bulletin: Anonymous/LulzSec Has Continued Success Using Rudimentary Hacking Methods

This Bulletin is being provided for your Executive Leadership, Operational Management, and Security Administrators situational awareness. The actors who make up the hacker group “Anonymous” and several likely related offshoots like “LulzSec”, continue to harass public and private sector entities with rudimentary exploits and tactics, techniques, and procedures (TTPs) commonly associated with less skilled hackers referred to as “Script Kiddies”. Members of Anonymous routinely claim to have an overt political agenda and have justified at least a portion of their exploits as retaliation for perceived ‘social injustices’ and ‘freedom of speech’ issues. Attacks by associated groups such as LulzSec have essentially been executed entirely for their and their associates’ personal amusement, or in their own hacker jargon “for the lulz”.

(U//FOUO) DHS LulzSec Bulletin: Hacktivist Groups Target U.S. and Foreign Networks

The National Cybersecurity and Communications Integration Center (NCCIC), through coordination with its partners and monitoring of multiple sources, is tracking reports that members of the hacktivist collectives ‘LulzSec’ and ‘Anonymous’ have combined their efforts and continue to perpetrate cyber attacks targeting U.S. and foreign networks. LulzSec Members have posted statements on the internet claiming the attacks, referred to as ‘Operation AntiSecurity’ (AntiSec), are ‘designed to demonstrate the weakness of general internet security’ and have allowed them to collect massive amounts of data. LulzSec is purported to be a group of former Anonymous members who typically use widely available and crude tools to hijack or deface web pages as a political statement. They also routinely post information regarding planned and ongoing activities on publicly available Internet Relay Chat (IRC) sessions and social networking sites like Twitter. Recent attacks by LulzSec and Anonymous have proven simple Tactics, Techniques and Procedures (TTPs) are often successful, even against entities who have invested a significant amount of time and capital into designing and securing their information networks.
