{"success":true,"data":{"id":"fake-lucidchart-lucidspark-diagramming-billing-phish","label":"Fake Lucidchart / Lucidspark diagramming and whiteboard subscription payment failed, team diagrams inaccessible, or shared boards and content suspended phishing","description":"Phishing emails impersonating Lucidchart or Lucidspark claiming the subscription payment has failed, team diagrams are inaccessible, shared boards are suspended, or diagramming content will be locked — directing them to update billing or restore their subscription through a credential-harvesting portal. Distinct from Miro/Mural visual collaboration billing phishing (which targets collaborative whiteboard tools) — this targets technical diagramming and architecture documentation tools with different use cases and user demographics. Key facts: (1) Lucidchart serves 30,000,000+ registered users with 25,000,000+ paying users ($7.95-9/month Individual/Team, $20+/user/month Enterprise) — Lucidchart is the default technical diagramming tool for software architecture diagrams, network topology charts, org charts, UML diagrams, ER diagrams, and business process flows; when a Lucidchart Team subscription lapses, all team-shared diagrams become inaccessible, including architecture documentation, infrastructure diagrams, and process flow charts that engineering and operations teams reference constantly; (2) Lucidchart's integration with Confluence, Jira, Google Workspace, and Microsoft 365 means billing suspension breaks embedded diagrams in documentation wikis — all Lucidchart diagrams embedded in Confluence pages show as broken, all Google Docs with embedded diagrams lose their visual content; (3) Lucidspark (Lucid's collaborative whiteboard product) serves teams who use it for sprint planning, brainstorming, and design thinking workshops — a 'your Lucidspark shared boards are suspended' email before a scheduled design sprint creates extreme urgency; (4) Architecture diagrams created in Lucidchart often represent months of work documenting system architecture, data flows, and infrastructure topology — 'your team diagrams will be suspended' threatens not just access to a tool but access to the organization's technical memory; (5) Lucidchart credentials expose all team diagrams including unreleased system architecture, network topology (which may reveal infrastructure security posture), organizational charts, and acquisition/expansion planning diagrams. Warning signs: sender not lucidchart.com/lucidspark.com/lucid.app; genuine Lucidchart billing at lucid.app/billing.","tier":"danger","category":"phishing","isThin":false}}
