Active Credentials Breach Secured: Major Library Collection Platform Protected

Challenge

CloudSEK’s contextual AI digital risk platform XVigil discovered that threat actors were sharing a series of documents containing various active credentials associated with a major public library collection platform.

The breach included account credentials that could be actively exploited by attackers. The credentials were found on the 135million-mail-access-combolist, a well-known cybercrime forum.

The credentials were associated with internal subdomains and emails, posing a significant security risk.

Impact

The exposure of active credentials can result in significant security risks, including unauthorized access to internal networks and sensitive information.

Attackers could exploit these credentials to gain deeper system access, leading to the theft of sensitive files, social engineering attacks, phishing campaigns, and identity theft.

Additionally, compromised systems could be misused for malicious activities, causing further damage to the platform's reputation and customer trust.

Solution

‍CloudSEK XVigil promptly identified and secured the exposed credentials, ensuring that sensitive data was protected and access was restricted

‍

Implementation:

Detection:

• CloudSEK XVigil discovered the active credentials on a cybercrime forum, exposing the library collection platform's internal subdomains and emails

‍

Threat Analysis:

• The exposed credentials could allow threat actors to gain unauthorized access to internal systems, potentially exposing sensitive data and internal infrastructure
• The analysis revealed that attackers could use the exposed credentials to conduct targeted attacks, social engineering, and identity theft

‍

Immediate Actions:

• Secured the exposed credentials by updating and rotating them to prevent further unauthorized access
• Implemented enhanced access controls, including multi-factor authentication (MFA) and role-based access control (RBAC)
• Disabled unnecessary accounts and credentials to reduce the attack surface

‍

Preventive Measures:

• Conducted regular security audits and penetration testing to ensure ongoing protection
• Strengthened security policies and educated users on best practices for handling sensitive information
• Implemented continuous monitoring and alerting to detect any unauthorized access attempts
• Educated development and IT teams on secure credential management practices to prevent similar breaches in the future
