The Microsoft 47 Leak: 113 Accounts, Fewer Than a Full Charter Bus

In May 2026, HEROIC analysts identified a combolist named microsoft 47, uploaded to Telegram by an individual user. The file contained 113 records of email addresses, plaintext passwords, and the URLs tied to Microsoft account logins. Why is this dangerous? With only 113 records, this file is small, but each entry is a working plaintext email and password pair tied to a Microsoft account, which often connects to email, cloud storage, and Office documents. An attacker only needs one of those 113 logins to be reused elsewhere to pivot into far more valuable accounts. Here is what was exposed in the microsoft 47 leak: email addresses, plaintext passwords, and associated URLs. Why this matters: Microsoft accounts frequently double as a single sign-on for email, work documents, and cloud backups, so a compromised login here can expose far more than just one inbox. Stolen credentials like these rarely stay in one place. Attackers feed lists like this into automated tools that test each email and password pair against banking sites, email providers, and online retailers, a technique known as credential stuffing. When a password is reused, one exposed account can lead directly to account takeover, identity theft, or financial fraud on completely unrelated services. How the microsoft 47 Combolist Was Put Together: This file appears to be a small, curated combolist focused specifically on Microsoft account logins, likely pulled from phishing pages or malware infections and filtered down to that one service. Curated lists like this are traded on Telegram precisely because every entry is pre-qualified to work against the same login page. Check If Your Microsoft Login Is Among the 113 Exposed Records: You do not have to wait to find out if your information is part of a leak like this one. HEROIC's free breach scanner checks your email address against a database of more than 400 billion exposed records, including combolists and stealer logs like this one, and tells you immediately if your credentials have shown up in a known breach. If you find a match, change that password right away, and avoid reusing it anywhere else.
