Grupo Hasar: 2.6K Lead Records Exposed in Data Leak

Data Breach Summary

A leak involving Grupo Hasar, a longstanding technology company based in Argentina, has surfaced on darkforums.st, reportedly published by the threat actor @N1KA. The exposed dataset includes approximately 2,690 lead records, potentially compromising names, emails, phone numbers (personal and work), job roles, IP addresses, and detailed user messages.

Grupo Hasar, known for delivering integrated solutions across business sectors for over 50 years, now faces a critical privacy issue as customer inquiries and submissions from their website have been publicly leaked.

Where and How?

The compromised data appears to have originated from web form submissions on the domain grupohasar.com, particularly from subdomains like desarrollo.grupohasar.com. The information was collected through contact forms and includes detailed metadata such as:

• User agent strings
• IP addresses
• Timestamped submission logs
• Comments/messages sent via contact forms
• Affiliate tracking fields
• UTM tracking parameters

The leaked content suggests poor web form sanitization and insufficient data protection practices around web submissions. Data was shared openly on a known underground forum, posing a risk of phishing attacks, identity theft, and spam.
