Hotmail Part2 17 Combolist Quietly Surfaced With 687,822 Logins

The Hotmail Part2 17 Combolist Quietly Surfaced With 687,822 Records: HEROIC analysts identified a combolist file labeled hotmail Part2 17 circulating on Telegram, dated February 7, 2023. The file contained 687,822 records, each combining an email address with a plaintext password and the URL the credentials are tied to. The Part2 17 naming indicates this file is one installment in a larger, ongoing series of Hotmail focused credential dumps. Why This Is Dangerous: A combolist this size, focused specifically on Hotmail linked accounts, gives attackers a large, targeted pool of email credentials to work with. Because email accounts are often used to reset passwords on other services, gaining access to someone's inbox can act as a master key into their broader online presence. What Was Exposed: email addresses, plaintext passwords, and URLs tied to each account. Why This Matters: With 687,822 credential pairs in circulation, attackers can run automated login attempts at scale, hoping password reuse gives them a way in. Because email inboxes control password resets for banking, shopping, and social media accounts, a compromised email is often the first domino in a chain that leads to identity theft and financial fraud. How Combolists Work: A combolist pairs usernames or emails with passwords, usually assembled from earlier breaches, stealer logs, or phishing campaigns, then filtered and grouped by theme, in this case by email provider. Sellers often release these collections in numbered parts, as seen in this file's Part2 17 label, building out a larger archive of targeted credentials over time.
