Eagle Builders Targeted by Interlock Ransomware Group: A Deep Dive into the Latest Cyber Threat

Introduction: A New Victim on the Ransomware Radar

Ransomware attacks continue to plague industries worldwide, with cybercriminal groups constantly evolving their tactics. One of the latest incidents involves a notorious threat actor, Interlock, who has reportedly compromised Eagle Builders, a company now listed among its victims on the dark web. This revelation, shared by ThreatMon’s Ransomware Monitoring division, adds yet another alarming entry to the growing database of cyberattacks in 2025.

the Incident 🧩

On June 13, 2025, at precisely 01:19:21 UTC+3, ThreatMon’s intelligence systems detected suspicious ransomware activity. The source? A familiar and dangerous player in the dark web underworld: the Interlock ransomware group. This group is now claiming responsibility for attacking Eagle Builders, a company that has now been officially added to their growing list of victims.

ThreatMon, a robust end-to-end threat intelligence platform, flagged this activity through its continuous monitoring of ransomware data across the dark web. Although the extent of the damage is not yet publicly known, the inclusion of Eagle Builders in Interlock’s published victim list strongly suggests that sensitive data may have been stolen, encrypted, or both.

Interlock is no newcomer to the scene. Known for its stealth, encryption capabilities, and rapid dissemination across networked environments, this group has been linked to several high-profile attacks over the past year. The group typically exfiltrates data before locking systems, giving them leverage during ransom negotiations.

The pattern is clear: compromise, encrypt, and demand a ransom—often in cryptocurrency. Victims are typically coerced through threats of data exposure if they refuse to pay. Eagle Builders now faces this grim reality, with potential business disruptions, reputational damage, and legal consequences looming over the horizon.

This attack underscores the vital need for proactive threat monitoring and swift incident response strategies. The public exposure of the breach not only affects the victim’s operations but also serves as a chilling reminder to other organizations operating in similar sectors.

What Undercode Say: 🔍 Cybersecurity Insights & Analysis

Interlock’s Growing Footprint

Interlock has been intensifying its operations, focusing on construction, infrastructure, and manufacturing sectors—industries where data security often takes a backseat to physical production. Eagle Builders fits that mold perfectly, making them an attractive target.

Vulnerability Exploitation

Undercode analysts suggest that Interlock may have gained access through known vulnerabilities, likely unpatched systems or phishing emails. Organizations that lag in security updates become easy prey for such sophisticated groups.

Tactics, Techniques, and Procedures (TTPs)

The Interlock ransomware group typically follows a triple-extortion model:

1. Data encryption – Locking out users from their systems

2. Data exfiltration – Stealing confidential files

1. Public exposure – Threatening to leak data if ransom isn’t paid

These TTPs create multifaceted pressure, making it harder for victims to recover without conceding to the attackers’ demands.

The Role of Threat Intelligence

ThreatMon’s rapid detection highlights the importance of threat intelligence platforms. Early alerts and real-time dark web monitoring can provide crucial minutes or hours that allow organizations to isolate systems, assess exposure, and prepare a response.

Industry-Wide Impact

This isn’t just a blow to Eagle Builders. Attacks like these ripple through the industry, affecting partnerships, compliance status, and investor confidence. Construction firms and similar businesses must now consider cybersecurity not as a cost, but as a core operational necessity.

Lessons for Other Companies

Audit all access points and perform regular penetration testing.
Train employees to recognize phishing and social engineering attempts.
Implement a strong backup and recovery strategy, including offline backups.
Work with threat intelligence firms to monitor potential exposures on the dark web.

Eagle Builders may now serve as a case study in what happens when advanced cybercriminal groups identify an under-protected target.

✅ Fact Checker Results

Interlock ransomware group has a verified history of targeting industry-specific victims.
ThreatMon is a reputable cybersecurity intelligence firm, with active monitoring of dark web activity.
Eagle Builders is confirmed to be listed on Interlock’s dark web leak site as of June 13, 2025.

🔮 Prediction

The ransomware threat landscape in 2025 is escalating, and we predict an increase in targeted attacks on mid-tier infrastructure companies over the next 6–12 months. Groups like Interlock will likely refine their targeting using stolen data, industry research, and AI-driven reconnaissance. Organizations that fail to act on warnings like this will continue to fall victim, often with devastating consequences. Cyber resilience must now be a non-negotiable boardroom priority.
