The LinkedIn_Business 3 Leak Contains Exactly 14,683 Login Records

HEROIC analysts found this file on Telegram on March 19, 2026. A Telegram user uploaded a combolist named LinkedIn_Business 3 containing exactly 14,683 records of email addresses and plaintext passwords, along with the login URLs tied to LinkedIn business accounts. Why This Is Dangerous: LinkedIn business accounts are often connected to a person's professional identity, company pages, and sometimes advertising or billing tools. A working login here could let an attacker impersonate a professional, message their contacts, or access any linked company advertising accounts. What Was Exposed: - Email addresses - Plaintext passwords - LinkedIn login URLs Why This Matters: Professionals whose credentials appear in this file risk more than just their LinkedIn profile. If the same password was used for a work email or another business tool, attackers can use credential stuffing to reach further into a person's professional and financial life. How a Platform-Specific Combolist Like This Works: This file is the third in a numbered series, LinkedIn_Business 3, suggesting the same source or group has released multiple batches of LinkedIn-linked credentials over time. These lists are typically built from phishing pages made to look like the real LinkedIn login screen or from credentials stolen by malware already running on a victim's device.
