The US Department of Health and Human Services’ Health Sector Cybersecurity Coordination Center (HC3) released this Analyst Note with insight into BazaCall campaigns in the healthcare sector. Even though the analysis is focused on the Healthcare and Public Health (HPH) Sector, all agencies and organizations are encouraged to review the information contained in the Analyst Note. Operating since as early as 2000, the threat actors behind BazaCall (also known as BazarCall), an advanced social engineering method, have been observed using multiple tactics, techniques, and procedures (TTPs) to breach targeted networks and lure unsuspecting victims into downloading its malicious malware. Many of these threat groups are offshoots of the defunct, notorious Russia-linked Conti gang, known to have aggressively targeted the HPH sector. Over time, these groups have since adopted and independently developed their own targeted phishing tactics that continuously evolve to target victims.   This HC3 Analyst Note provides an overview and examination of these groups, their TTPs, target industries and victim countries, impact to the HPH sector, indicators of compromise, and recommended defense and mitigations. This advisory is being provided to assist all agencies and organizations in guarding against the persistent malicious actions of cyber criminals.

Incident response is a critical part of cybersecurity risk management and should be integrated across organizational operations. The six Functions of the NIST Cybersecurity Framework (CSF) 2.0 all play vital roles in incident response.

NIST is releasing the initial public draft of Special Publication (SP) 800-61r3 (Revision 3), Incident Response Recommendations and Considerations for Cybersecurity Risk Management: A CSF 2.0 Community Profile, for public comment. This publication seeks to assist organizations with incorporating cybersecurity incident response recommendations and considerations throughout their cybersecurity risk management activities, as described by CSF 2.0. Doing so can help organizations prepare for incident responses, reduce the number and impact of incidents that occur, and improve the efficiency and effectiveness of their incident detection, response, and recovery activities.

The public comment period is open through May 20, 2024. See the publication details for a copy of the draft and instructions for submitting comments.

Readers are encouraged to utilize online resources on NIST’s new Incident Response project page in conjunction with this document to access additional information on implementing these recommendations and considerations.

Event Date: May 2, 2024

Event Time: 2:00 p.m. to 2:45 p.m. ET

Event Location: Virtual

Event Description:

Join us on May 2, 2024, for a 30-minute fireside chat with the NIST MEP Program Office. During this webinar we will highlight the cybersecurity resources available to the nation’s small and medium-sized manufacturers (SMMs).

SMMs are increasingly relying on data, information, and technologies to run their operations in a competitive and efficient manner. With this increased reliance on technology and connectivity comes an increased cybersecurity threat surface to the business and to the entire supply chain in which they contribute.

Defending an SMM’s assets from cybersecurity threats can be challenging. However, because these organizations often have less complex information technology (IT) and operational technology (OT) infrastructures, many can more readily take basic steps to defend their information and systems. 

The MEP National Network helps manufacturers of all sizes manage their cybersecurity and privacy risks by providing guidance, solutions, and training that is practical, actionable, and cost-effective.  

During this webinar, we’ll have a robust discussion to provide attendees with:

• An introduction to the MEP National Network
• An overview of the MEP cybersecurity services and resources
• Basic steps an SMM can take to manage their cybersecurity risks
• Information about how to locate an MEP Center in your area

We’ll reserve time at the end of the webinar to address questions.

Speakers: 

• Dr. Jyoti Malhotra, Division Chief, National Programs, NIST MEP
• Savann Thorn, IT Specialist (Security), NIST MEP
• Daniel Eliot, Lead for Small Business Engagement, Applied Cybersecurity Division, NIST

The Federal Trade Commission (FTC) released a report stating that over $1.1 billion in losses from impersonation scams were reported in 2023. The FTC’s report shows that 330,000 incidents were business impersonation scams, and nearly 160,000 were government impersonation scams, accounting for almost half of the frauds reported to the agency. Reports also show an increase in multi-stage impersonation scams where threat actors pose as more than one organization in a single scam. Threat actors may initially begin the scam by posing as an employee of a trusted organization and then transfer the target to someone claiming to be from a bank or government agency to add legitimacy to their scam.

Phone calls are still the top reported initial stage of impersonation scams but have seen a sharp decline compared to 2020. Emails are a close second, followed by text messages, and both have steadily increased in usage over the past few years. The below list of scams accounted for nearly half of the reported 2023 scams.

Copycat Account Security Alerts: Threat actors initiate fraudulent messages of suspicious account activity or unauthorized charges, claiming to be from a trusted organization or bank. They try to persuade their target to transfer funds or move money to a Bitcoin ATM, claiming it will help “protect” their funds. Phony Subscription Renewals: Users receive a notice claiming that a subscription or account will auto-renew, often claiming the charge will be for a few hundred dollars. Threat actors sometimes try to convince their target to allow them to connect to their computer, making it appear that they “accidentally” refunded too much money to the target. The threat actors demand that the refund be returned, often through the purchase of gift cards. Fake Giveaways, Discounts, or Money to Claim: Threat actors send a message about a giveaway, discount, or unclaimed money. These messages appear to be sent from organizations, such as internet service providers, retailers, or the Publishers Clearing House. These scams require purchasing gift cards or transferring funds to receive a gift or discount. Bogus Problems with the Law: Threat actors impersonating government agents contact the target, claiming their identity has been used to commit a serious crime. They offer to help fix the problem, often by having their targets purchase gift cards or transfer funds to Bitcoin ATMs (or “safety lockers”) to protect their funds during the supposed investigation. Made-up Package Delivery Problems: Threat actors send messages claiming to be from carrier services, stating they are having problems making the delivery. These messages will include a link to the spoofed website of the carrier’s website, which may prompt for credit card or bank account information for a small redelivery fee.

On April 1, the FTC announced a new rule regarding the impersonation of government agencies and businesses. This rule gives the agency more robust tools to fight and deter potential scammers. Due to the new rule, the FTC can file federal court cases seeking money back for victimized consumers and pursue civil penalties against those who violate the rules.

The NJCCIC continues to receive reports of ransomware incidents impacting New Jersey private organizations and the public sector. Threat actors primarily targeted critical infrastructure and educational institutions, likely due to budgetary restraints, limited resources, and reliance on third-party vendors. These incidents resulted in financial losses, operational disruptions, and the loss of confidentiality, integrity, and availability of data and information systems. For the first quarter of 2024, we review the top ransomware variants reported to the NJCCIC, highlight ransomware trends, and provide recommendations to educate users and organizations to reduce the likelihood of victimization.

For the first quarter of 2024, ransomware incidents reported to the NJCCIC consisted of Akira, LockBit, and Play ransomware. There was a sharp increase in Akira ransomware attacks, particularly after the LockBit ransomware group’s takedown. Akira ransomware operators are known for their sophisticated attacks, especially against US healthcare organizations. However, after the takedown, LockBit quickly relaunched operations to stay active and focused on targeting government agencies and critical infrastructure organizations, including healthcare. Also, cyberattacks targeting ConnectWise ScreenConnect vulnerabilities were linked to both LockBit and Play ransomware. Although existing ransomware groups continue their efforts, new ransomware gangs have initiated operations in 2024.

The top attack vectors for ransomware are phishing, compromising valid accounts, and external remote services. Threat actors are using artificial intelligence at an increased rate to generate targeted and sophisticated phishing campaigns and launch successful, profitable ransomware attacks. They also exploited vulnerabilities to infiltrate systems and networks, as predicted in the mass exploitation of technologies supporting hybrid and remote work and enterprise third-party file transfer solutions, such as virtual private networks (VPNs), cloud-based storage, and multi-factor authentication (MFA) tools.

An example of an initial attack vector in ransomware incidents reported to the NJCCIC was unauthorized remote login access via a VPN service. One of the tactics used was MFA prompt bombing , in which threat actors obtained account credentials and attempted to log in multiple times. They sent an overwhelming number of MFA authentication requests, hoping that the target would be distracted and unintentionally provide access or eventually give in due to fatigue and approve the request. The target could refrain from resisting temptation and approving the multiple notifications. This observed tactic has recently evolved into the threat actors calling the target from a spoofed support number to convince them to initiate a password reset and divulge the one-time password reset code.

Once threat actors gained unauthorized access, they infiltrated the target organization, gained access to internal systems, and moved laterally to other critical systems. Once data was exfiltrated, they encrypted systems and servers, shutting down access to critical services and files containing personally identifiable information (PII) and financial information. Additionally, the ransomware incidents affected onsite backups; therefore, victim organizations had to resort to offsite backups, if available and viable for restoration.

Ransomware remains a prevalent threat as extortion tactics continue and evolve to pressure victim organizations to pay the ransom. Threat actors used extortion tactics, such as denying access to encrypted files, stealing data, and threatening a data breach by posting on public ransomware leak sites or releasing the stolen data to regulators, clients, or patients. The additional tactic of swatting to pressure the victim organization into paying the ransom and gaining media coverage raises public safety concerns.
