LUCR-3: Unveiling the Financially Motivated Threat Actor in the Cloud

In the ever-evolving landscape of cyber threats, a new player has emerged: LUCR-3. This financially motivated threat actor has gained notoriety for its sophisticated operations in the cloud. In this article, we delve into the inner workings of LUCR-3, exploring their techniques, motivations, and the impact they have on their victims. Understanding their methods is crucial in order to enhance cybersecurity defenses and protect sensitive data from falling into their hands.

LUCR-3’s Operations in the Cloud

LUCR-3 leverages the power of Windows 10 systems and utilizes GUI utilities to carry out its missions in the cloud. This preference for Windows 10 provides the group with a familiar environment for executing its malicious activities. Moreover, LUCR-3 targets victim organizations’ software deployment solutions, such as SCCM, to deploy specified software to the target systems. By exploiting these existing infrastructures, the group can infiltrate its targets more effectively.

Initial Access Techniques

LUCR-3 heavily relies on targeting Identity Providers (IDPs) for their initial access. They employ various methods, including purchasing credentials from common marketplaces and bypassing Multi-Factor Authentication (MFA) mechanisms through techniques like SIM swapping, social engineering, and exploiting push fatigue. This comprehensive approach to initial access ensures that LUCR-3 can successfully penetrate their targets.

Furthermore, LUCR-3 invests considerable effort in researching its victims before initiating attacks. They carefully select identities that will grant them elevated privileges, allowing for greater control and access within the targeted organization. In a particularly cunning move, LUCR-3 ensures that the sourced identities have geolocations similar to their victim identities, reducing the likelihood of triggering impossible travel alerts.

Data Theft and Extortion

Financial gain is the ultimate goal for LUCR-3. To achieve this, they employ data theft as a means to extort their victims. The stolen sensitive data serves as leverage, with LUCR-3 demanding exorbitant sums, often in the range of tens of millions of dollars, to prevent the public release or sale of this information. Their ability to pilfer valuable data poses a significant risk, both in terms of financial implications and reputational damage for the targeted organizations.

Intelligence gathering and targeted search

LUCR-3’s success lies in their comprehensive intelligence gathering techniques. They use search terms specifically crafted to uncover credentials, gain insights into the software deployment environments, understand the code signing process, and locate sensitive data stores. This meticulous preparation enables them to exploit vulnerabilities efficiently, maximizing their chances of success.

Privilege Escalation Techniques

Once inside a target environment, LUCR-3 does not rest. They employ various privilege escalation techniques to gain unauthorized access to valuable resources. Policy manipulation and updating login profiles are some of the methods they utilize to increase their privileges within the victim’s infrastructure. Additionally, LUCR-3 is adept at harvesting credentials from platforms like Secrets Manager in Amazon Web Services (AWS), further elevating their control and access.

Maintaining Identity Access

LUCR-3 understands the importance of maintaining easy and continued access to their victims’ identities. To ensure this, they register their own devices and add alternate MFA options, effectively securing their hold on the compromised identity. By taking these precautions, they circumvent any potential obstacles that could hinder their ongoing access to critical systems and information.

Defense Evasion Tactics

LUCR-3 employs a range of defense evasion techniques to avoid detection and prolong their unauthorized presence. They disable AWS GuardDuty, a threat detection service, to remain undetected by security measures. Simultaneously, LUCR-3 takes steps to stop logging, making it challenging to trace their activities. Additionally, they leverage the serial console access in AWS to further evade detection and maintain their covert operations.

Data Theft in SaaS Applications

Expanding their reach beyond traditional environments, LUCR-3 targets Software-as-a-Service (SaaS) applications as well. They employ sophisticated tactics to search for and download sensitive documents hosted on these platforms. Furthermore, they exploit Continuous Integration/Continuous Deployment (CI/CD) tools to clone and archive source code. By compromising SaaS applications and leveraging CI/CD tools, LUCR-3 increases their potential rewards and amplifies the damage caused to their victims.

LUCR-3 represents a formidable threat in the world of cybercrime. Their financially motivated tactics, coupled with their sophisticated techniques, make them a force to be reckoned with. To combat this threat effectively, organizations must remain vigilant, regularly update their security measures, and implement robust defense mechanisms. By understanding the inner workings of LUCR-3 and prioritizing cybersecurity, we can strive to protect our sensitive data and thwart their malicious intentions.
