Brinztech Alert: The Alleged Database of Repediu is Leaked

Dark Web News Analysis

The dark web news reports a massive data privacy and supply chain incident involving Repediu, a prominent Brazilian Customer Relationship Management (CRM) and food marketing platform tailored specifically for restaurants and delivery services. A threat actor on a hacker forum is currently advertising the leak of the company’s core backend databases, allegedly exfiltrated in February 2026.

The scale of the compromised dataset is catastrophic. The data has reportedly been dumped into three distinct, easily parseable CSV files: users.csv (containing 2,633 records of platform administrators and agency partners), leads.csv (containing 1.2 million records of prospective B2B clients), and a massive customers.csv containing 21.4 million records of end-consumers. The leaked fields expose highly sensitive Personally Identifiable Information (PII) across all three files, including Names, Phone Numbers, Emails, Birth Dates, and specific Company Details.

Key Cybersecurity Insights

Breaches of centralized marketing and CRM platforms are “Tier 1” supply chain threats because they aggregate the consumer data of thousands of independent businesses into a single, highly lucrative target:

• Third-Party Supply Chain Exposure: Repediu acts as the centralized marketing engine for thousands of delivery brands, franchises, and restaurants across Brazil. A breach of this aggregator bypasses the security of the individual restaurants and directly exposes their end-customers. The leak of 21.4 million consumer records highlights the severe, cascading blast radius of compromising a B2B2C service provider.
• Severe LGPD Compliance Liability: Under Brazil’s General Data Protection Law (LGPD), companies are subject to strict data governance and mandatory breach notification timelines. The exposure of PII for over 20 million Brazilian citizens exposes the organization to massive administrative fines from the National Data Protection Authority (ANPD)—up to 2% of gross revenue, capped at R$ 50 million per infraction—alongside devastating class-action civil liability.
• Hyper-Targeted Consumer Scams (“Smishing”): The straightforward CSV format of this leak makes it incredibly easy for low-tier cybercriminals to weaponize the data. Attackers can load the Phone Numbers and Names into automated SMS platforms to launch highly convincing “smishing” (SMS phishing) campaigns. They can impersonate local restaurants or major delivery apps, claiming an “issue with a recent order” or offering a “promotional PIX discount,” routing victims to credential-harvesting or payment-skimming websites.
• B2B Extortion & Spear-Phishing: The exposure of the users.csv and leads.csv files, which contain Company Details, puts Repediu’s direct clients (restaurant owners, marketing agencies, and consultants) in immediate danger. Threat actors can leverage this B2B intelligence to launch targeted Business Email Compromise (BEC) scams or attempt to extort the restaurant operators directly.

Mitigation Strategies

To protect the massive consumer base and attempt to mitigate the impending regulatory fallout, the following strategies must be implemented immediately:

• LGPD Notification & Compliance: Repediu’s legal counsel must urgently engage with the ANPD to self-report the breach. Furthermore, transparent communication must be issued to all affected B2B clients (the restaurants) so they can, in turn, notify their end-consumers about the risk of targeted phishing.
• Password Reset Enforcement: Immediately invalidate all active sessions across the Repediu platform and enforce a mandatory, global password reset for all 2,633 administrative and client user accounts to block any immediate account takeover (ATO) attempts.
• Vulnerability Assessment (Pentesting): Conduct a thorough, third-party vulnerability assessment and penetration test of the platform’s API endpoints and cloud storage buckets to identify exactly how threat actors were able to export over 22 million total records into CSV files undetected.
• Enhanced Threat Monitoring: Implement rigorous enhanced monitoring on all internal systems and client portals to detect any anomalous data extraction patterns or unauthorized access attempts using compromised employee credentials.
