Operation Doppelbrand Is Not Doppel, But It Signals a Growing Threat

We’re aware of recent reporting about a new brand impersonation campaign called Operation DoppelBrand. While the name bears a resemblance to Doppel, we want to clearly state that this campaign is not affiliated with nor connected to our company in any way.

Operation DoppelBrand Is Not Doppel, But It Signals a Growing Threat

This campaign illustrates the industrialization of modern brand impersonation. Driven by the threat actor group GS7, the operation targets Fortune 500 organizations using "digital doubles" or near-perfect clones of corporate login pages designed to harvest credentials at scale. Once access is gained, GS7 weaponizes legitimate Remote Monitoring and Management (RMM) tools to maintain a persistent, hidden presence. By mirroring trusted brands with high fidelity, attackers effectively turn a company’s own reputation and infrastructure into a vehicle for cyberattacks.


In an era of AI-driven deception, proactive detection and human resilience are essential. Doppel provides the first AI-native Social Engineering Defense platform, unifying Digital Risk Protection and Human Risk Protection into a single, closed-loop shield. Because attackers don’t distinguish between digital and human targets, we bridge intelligence "out there" with behavior "in here" to stop attacks before they scale.


Doppel’s Brand Protection product moves beyond simple detection to autonomously dismantle attacker infrastructure, achieving a median takedown time of under 10 hours across domains, social, ads, and email. By combining this rapid disruption with hyper-realistic simulations and role-based coaching, Doppel ensures your people lead the defense rather than just reacting to alerts.


Don’t wait for a breach to discover a brand clone. Contact Doppel today and see how we protect your brand, employees, and customers.
