FBI Cyber Bulletin: APT Targeting U.S. Private Sector, Government Networks Using Presidential Election Lures

Likely Advanced Persistent Threat (APT) cyber actors have targeted US private sector and government networks since August 2016 with spear phishing campaigns, using newly identified exploits contained within lures related to foreign affairs and the recent US presidential election. The FBI analyzed malicious Microsoft Office documents, a zip archive, a first-stage downloader, a second-stage in-memory-only PNG wrapped malware, and a BAT-initiated PowerShell script associated with the campaigns. This FLASH provides rules and signatures to assist in network defense efforts.

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.

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.

Declassified 28 Pages From Congressional 9/11 Investigation

While in the United States, some of the September 11 hijackers were in contact with, and received support or assistance from, individuals who may be connected to the Saudi Government. There is information, primarily from FBI sources, that at least two of those individuals were alleged by some to be Saudi intelligence officers. The Joint Inquiry’s review confirmed that the Intelligence Community also has information, much of which has yet to be independently verified, indicating that individuals associated with Saudi Government in the United States may have other ties to al-Qa’ida and other terrorist groups. The FBI and CIA have informed the Joint Inquiry that, since the September 11 attacks, they are treating the Saudi issue seriously, but both still have only a limited understanding of the Saudi Government’s ties to terrorist elements. In their testimony, neither CIA nor FBI witnesses were able to identify definitively the extent of Saudi support for terrorist activity globally or within the United States and the extent to which such support, if it exists, is knowing or inadvertent in nature.

FBI Bulletin: Criminals Hacking Law Firms to Steal Information for Insider Trading

A financially motivated cyber crime insider trading scheme targets international law firm information used to facilitate business ventures. The scheme involves a hacker compromising the law firm’s computer networks and monitoring them for material, non-public information (MNPI). This information, gained prior to a public announcement, is then used by a criminal with international stock market expertise to strategically place bids and generate a monetary profit.

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.

FBI Flash Alerts on MSIL/Samas.A Ransomware and Indicators of Compromise

The FBI previously identified that the actor(s) exploit Java-based Web servers to gain persistent access to a victim network and infect Windows-based hosts. The FBI also indicated that several victims have reported the initial intrusion occurred via JBOSS applications. Further analysis of victim machines indicates that, in at least two cases, the attackers used a Python tool, known as JexBoss, to probe and exploit target systems. Analysis of the JexBoss Exploit Kit identified the specific JBoss services targeted and vulnerabilities exploited. The FBI is distributing these indicators to enable network defense activities and reduce the risk of similar attacks in the future.

FBI Cyber Bulletin: Smart Farming May Increase Cyber Targeting Against US Food and Agriculture Sector

The FBI and the US Department of Agriculture (USDA) assess the Food and Agriculture (FA) Sector is increasingly vulnerable to cyber attacks as farmers become more reliant on digitized data. While precision agriculture technology (a.k.a. smart farming)a reduces farming costs and increases crop yields, farmers need to be aware of and understand the associated cyber risks to their data and ensure that companies entrusted to manage their data, including digital management tool and application developers and cloud service providers, develop adequate cybersecurity and breach response plans.

FBI Cyber Bulletin: Global Extremists Conducting Cyber Activity in Support of ISIL

Over the past 18-24 months, an unknown number of online extremists have conducted “hacktivist” cyber operations – primarily Web site defacements, denial-of-service attacks, and release of personally identifiable information (PII) in an effort to spread pro-Islamic State of Iraq and the Levant (ISIL) propaganda and to incite violence against the United States and the West. Recent open source reporting from the Daily Mail India, indicates ISIL is recruiting Indian hackers and offering upwards of $10,000 USD per job to hack government Web sites, steal data, and to build social media databases for recruiting purposes. Indian officials believe as many as 30,000 hackers in India may have been contacted. The FBI cannot confirm the validity of the media reports, and beyond this single article on Indian hackers and ISIL, does not have information indicating any such relationship exists to date. The FBI assesses this activity is most likely independent of ISIL’s leaders located in Syria and Iraq.

FBI Cyber Bulletin: Chinese Hackers Targeting U.S. Navy Contractors

The FBI has obtained information regarding a group of cyber actors who have compromised and stolen sensitive military information from US cleared defense contractors (CDCs) through cyber intrusions. This group utilizes infrastructure emanating from China to conduct their nefarious computer network exploitation (CNE) activities. Information obtained from victims and subsequent analysis indicates that they were targeted based on their US Navy Seaport Enhanced contracts. The actors did not target information pertaining to a specific contract but instead stole all information that they accessed via their malicious cyber activities. Any activity related to this group detected on a network should be considered an indication of a compromise requiring extensive mitigation and contact with law enforcement.

(U//FOUO) DHS-FBI Bulletin: Criminal Hackers Target Police to Protest Perceived Injustices

Disruptive cyber attacks by criminal hackers—primarily distributed-denial-of-service (DDoS) attacks—targeting local law enforcement websites have increased since August 2014. We judge that this is almost certainly a result of the heightened coverage surrounding the alleged use of excessive force by law enforcement and an increased focus on incidents of perceived police brutality. The primary impact from the majority of these attacks has been the temporary disruption of the targeted public-facing websites.

(U//LES) FBI Suicide Vest and Belt Use in Middle East, Africa, and Europe Show Minimal Signs of Tactic Migration

The FBI Terrorism Explosive Device Analytical Center (TEDAC) assesses the tactics used to construct suicide vest and belt improvised explosive devices (IEDs) in the Middle Eastern, African, and European regions likely have minimal correlation. Use of these tactics allows suicide bombers to discretely move to a desired target location and make real-time decisions to maximize lethality. The suicide belt design allows the wearer to conceal the device and blend in with their surrounding environment, as well as to position themselves in potentially crowded environments while not raising suspicion.
