OWA_Logins Combolist: 8,851 Login Credentials Leaked Online

In March 2026, HEROIC analysts identified a combolist file named OWA_Logins circulating in a Telegram channel. The file contained 8,851 records pairing email addresses with plaintext passwords and associated login URLs. Why This Combolist Is Dangerous: Every credential in this file is stored in plaintext, meaning anyone who downloads it can immediately try the email and password pairs on other websites without needing to crack or decode anything. Because the URLs are included alongside each pair, attackers know exactly which service each login belongs to, making automated abuse faster and more targeted. What Was Exposed: - Email addresses - Plaintext passwords - Login URLs tied to each account Why This Matters: If you reuse a password across multiple sites, a single exposed combolist like OWA_Logins can give an attacker access to your email, banking, or social media accounts through credential stuffing. Attackers run these lists against hundreds of websites automatically, testing each pair until one works. How a Telegram Combolist Like This Works: Combolists such as OWA_Logins are usually compiled from older breaches, phishing pages, or malware-infected devices, then repackaged and shared for free or sold in Telegram channels used by cybercriminals. They rarely come from a single hacked company. Instead they are collections stitched together from many smaller sources, which is why the file is named generically rather than after a specific brand. Check If You Are Affected: HEROIC's free breach scanner checks your email address against more than 400 billion leaked records, including combolists like this one. Run a scan to find out if your credentials were part of this exposure and get guidance on which passwords to change.
