Sophisticated Attack on Born Group
- Initial Access: Threat Actor exploits CVE-2024-23897 on an exposed Jenkins server.
- LFI Vulnerability Exploitation: Threat Actor uses CVE-2024-23897 (LFI vulnerability) to steal SSH keys.
- Access to GitHub: Threat Actor uses stolen SSH keys to access the GitHub repository of borngroup.com.
- Repository Dump: Threat Actor dumps all repositories from BORN Group’s GitHub.
- Infiltration of Other Victims: Threat Actor exploits hardcoded keys and secrets found in the source code to infiltrate other systems.
BORN Group as Primary Target
- Shared Folder Structure: Consistent "born" folder naming conventions across multiple repositories suggest a centralized role for BORN Group in the affected environment.
- Customer Overlap: The identification of incident victims as BORN Group clients reinforces the company's potential involvement as a primary target.
Exposed Vulnerable Server
The discovery of an exposed BORN Group server running vulnerable Jenkins software strengthens the hypothesis that the company was a direct target of the attack.
Threat Actor Profile - Intelbroker
Intelbroker is a highly active e-crime threat actor operating since at least October 2022. Primarily motivated by financial gain, Intelbroker specializes in data breaches, extortion, and operating as an access broker within the cybercriminal underground. The actor frequently targets high-profile organizations across various sectors, including government, telecommunications, automotive, and technology.
Modus Operandi
Intelbroker employs a multi-faceted approach to compromise targets and profit from stolen data:
- Data Breaches: Breaching organizations to steal sensitive data, including customer PII, financial records, and proprietary source code.
- Extortion: Leveraging stolen data to extort victims through threats of public disclosure or sale to other cybercriminals.
- Access Brokerage: Selling access to compromised networks and systems, providing other threat actors with an entry point for further attacks.
Tools and Techniques
- Endurance Ransomware: Intelbroker claims to have developed and operated the "Endurance" ransomware. This C#-based malware, acting more as a wiper, overwrites files with random data, renames them, and then deletes the originals. The source code for Endurance is publicly available on a GitHub repository believed to belong to the actor.
- Exploiting Jenkins Servers: Intelbroker commonly targets exposed Jenkins servers, leveraging vulnerabilities for initial access and lateral movement within victim networks.
- Third-Party Compromise: In at least one case involving T-Mobile (which the company denies), Intelbroker may have compromised a third-party service provider to gain access to the target organization's network.
Notable Claims and previous Activities:
- Autotrader
- Volvo
- AT&T
- Verizon
- T-Mobile (disputed)

Recommendations
- Organizations using Jenkins should immediately patch their systems to address CVE-2024-23897.
- Companies utilizing Born Group's services should conduct a thorough security audit to identify any potential compromises.
- Review and strengthen access controls for all repositories, especially those containing sensitive information.
- Implement multi-factor authentication (MFA) wherever possible to mitigate the risk of credential compromise.
- Monitor for suspicious activity related to data access and exfiltration.
