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.

FBI Cyber Bulletin: Individuals Threatening Distributed Denial of Service of Private-Sector Companies for Bitcoin

An individual or group claiming to be “Anonymous” or “Lizard Squad” sent extortion emails to private-sector companies threatening to conduct distributed denial of service (DDoS) attacks on their network unless they received an identified amount of Bitcoin. No victims to date have reported DDoS activity as a penalty for non-payment.

(U//FOUO) DHS-FBI-USSS Joint Threat Assessment 2017 Presidential Address to a Joint Session of Congress

This Joint Threat Assessment (JTA) addresses threats to the 2017 Presidential Address to a Joint Session of Congress (the Presidential Address) at the US Capitol Building in Washington, DC, on 28 February 2017. This assessment does not consider nonviolent civil disobedience tactics (for example, protests without a permit) that are outside the scope of federal law enforcement jurisdiction; however, civil disobedience tactics designed to cause a hazard to public safety and/or law enforcement fall within the scope of this assessment.

(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) FBI Counterintelligence Note: Chinese Talent Programs

Chinese Talent Programs are a vital part of Chinese industry. Talent programs recruit experts to fill technical jobs that drive innovation and growth in China’s economy. National, provincial, and municipal talent recruitment programs provide opportunities for experts to work in industry and academic organizations supporting key areas deemed critical to China’s development. The talent programs recruit experts globally from businesses, industry, and universities with multiple incentives to work in China. Associating with these talent programs is legal and breaks no laws; however, individuals who agree to the Chinese terms must understand what is and is not legal under US law when sharing information. A simple download of intellectual property (IP) or proprietary information has the potential to become criminal activity.

FBI Cyber Bulletin: Identification of Locky Ransomware

The ‘Locky’ malware is a ransomware variant, which has extensively utilized spam campaigns to distribute malicious files that download and execute code capable of encrypting numerous critical file types on both local and networked file stores. Encrypted files are renamed with a unique hexadecimal filename and receive the “.locky” extension. Each directory containing encrypted files contains instructions on how to utilize Bitcoin in order to pay a ransom for file recovery, and the system’s computer background is also changed to contain payment instructions. Recovery of encrypted files is impossible without data backup or acquisition of the private key due to the well-implemented, strong encryption. Historically, while payment of the ransom may result in receipt of the valid private key, enabling decryption of the targeted files, the FBI does not recommended the victim pay the ransom.

FBI Cyber Bulletin: United Cyber Caliphate Releases PII of U.S. Business Personnel Directory

As of 5 May 2016, the Islamic State of Iraq and the Levant (ISIL) Sympathizer hacking group United Cyber Caliphate (UCC) defaced a Nigerian-hosted Web site, posting an html file containing the heading “USA Online Company Data Dumped by United Cyber Caliphate,” there was no other message or threat associated with the file. The file contained approximately 1,137 entries, many of which appeared to be US-based individuals with corresponding personally identifiable information (PII) fields such as name, company, e-mail, phone, city, state, and zip code. The PII was doxed from the personnel directory of a US business, according to FBI and open source reporting.

FBI Cyber Bulletin: Android Malware Phishing for Financial Institution Customer Credentials

The FBI has identified two Android malware families, SlemBunk and Marcher, actively phishing for specified US financial institutions’ customer credentials. The malware monitors the infected phone for the launch of a targeted mobile banking application to inject a phishing overlay over the legitimate application’s user interface. The malware then displays an indistinguishable fake login interface to steal the victim’s banking credentials. According to cyber threat industry reports, both malware families have targeted foreign financial institutions since 2014, gradually broadening the list to include Western banks, and offered the malware for lease or purchase, respectively, in underground forums. At least as of December 2015, the malware expanded its configuration to include the Android package names of US financial institutions.

FBI Cyber Division Bulletin: KeySweeper Wireless Keystroke Logger Disguised as USB Device Charger

KeySweeper is a covert device that resembles a functional Universal Serial Bus (USB) enabled device charger which conceals hardware capable of harvesting keystrokes from certain wireless keyboards. If placed strategically in an office or other location where individuals might use wireless devices, a malicious cyber actor could potentially harvest personally identifiable information, intellectual property, trade secrets, passwords, or other sensitive information. Since the data is intercepted prior to reaching the CPU, security managers may not have insight into how sensitive information is being stolen.
