The Securityish Brief
Iron Mountain, headquartered in Portsmouth, New Hampshire, specializes in data centers and records management, serving over 240,000 customers worldwide, including 95% of the Fortune 1000. Recently, the Everest extortion gang claimed to have stolen 1.4 TB of internal company documents, which included personal documents and information on clients. However, Iron Mountain clarified that the breach was limited to a single folder containing marketing materials.
The attackers gained access through compromised login credentials, specifically targeting a folder on a file-sharing server. Iron Mountain confirmed that no ransomware or malware was deployed, and no other systems were affected during this incident. The compromised credential has since been deactivated, ensuring that the breach does not pose further risks.
The Everest ransomware group, which has been active since 2020, has shifted its focus from encrypting systems to data-theft-only extortion. This change reflects a broader trend in cybercrime, where threat actors increasingly target sensitive corporate data for financial gain. The group has been known to act as an initial access broker, selling access to breached networks to other cybercriminals.
In August 2024, the U.S. Department of Health and Human Services warned that Everest was increasingly targeting healthcare organizations across the United States, underscoring the potential risks to sensitive data in critical sectors. The group’s tactics have evolved, and they have added hundreds of victims to their leak portal, which is used for double-extortion attacks.
This incident serves as a reminder for organizations to remain vigilant against credential theft and to ensure that access controls are robust. As cyber threats continue to evolve, understanding the tactics employed by groups like Everest can help organizations better prepare and protect their sensitive information.
