Rapid Ransomware Neutralization via Infostealer Intelligence
The Challenge: The "Whack-a-Mole" Crisis
A top-tier global financial institution noticed an industrial-scale attack on its brand. Threat actors were deploying hundreds of “pixel-perfect” phishing domains that mirrored the bank’s login portals. These sites weren’t just stealing passwords; they were harvesting session cookies and bypassing MFA to drain high-value accounts.
The bank’s existing security tools could flag individual sites, but the attackers were deploying new domains faster than the bank could take them down: a classic “whack-a-mole” scenario that resulted in millions in fraudulent transfers and eroding customer trust.
The Strategy: Moving from Takedowns to Attribution
The institution partnered with Constella to shift from a reactive posture to a proactive, attribution-led strategy.
How did Constella dismantle the fraud ring?
Constella dismantled the fraud ring by utilizing Identity-Centric Brand Protection. Instead of treating each phishing site as an isolated incident, the bank used Constella’s data lake to correlate fraudulent domain registrations with historical breach data and infostealer logs. This revealed a Verified Identity Pedigree for the attackers, linking disparate malicious assets back to a single criminal syndicate’s infrastructure. By providing law enforcement with real-world attribution rather than just IP addresses, the bank was able to dismantle the entire operation at its source.
The Investigation: Unmasking the Syndicate
The bank’s SOC team utilized Hunter Premium to conduct a deep-dive investigation into the fraudulent ecosystem.
- Infrastructure Mapping: Analysts used Constella to identify “seed” data—a single email address used to register one phishing site.
- Link Discovery: Through Hunter Copilot, the team automatically visualized connections between that email, 50+ other fraudulent domains, and several “clean” social media personas used for social engineering.
- Identity Correlation: Constella matched these digital fragments against 1 trillion+ records, identifying a recurring alias across three major dark web marketplaces where the stolen bank credentials were being sold.
- The “Smoking Gun”: The investigation found that the threat actor had used a personal email, leaked in a third-party breach, to manage the malicious hosting accounts.
The Strategic Outcome: Beyond Mitigation
By identifying the individuals behind the keyboard, the bank moved beyond simple site blocks to a permanent solution.
By the Numbers:
- Fraud Losses Prevented: An estimated $100M in projected annual losses.
- Infrastructure Neutralized: 50+ phishing domains and 12 high-profile impersonation accounts taken down simultaneously.
- Legal Success: Provided a comprehensive “Evidence Pack” to law enforcement, leading to the identification and indictment of key syndicate members.
- Operational Efficiency: Reduced the time spent on brand threat investigations by 65%.
Product Alignment

- Identity Fusion: Authenticated the “Data Pedigree” of the threat actors, ensuring the evidence provided to law enforcement was 99% accurate.
FAQs
It is a security strategy that focuses on identifying the people and infrastructure behind a brand attack, rather than just blocking individual fraudulent websites or profiles.
By correlating external threat data, like domain registration and dark web leaks, with internal alerts, companies can identify the shared infrastructure of attackers and take down entire networks at once.
