The Monidays Breach: 247 Stolen Passwords and Email Addresses Leaked

HEROIC analysts discovered the Monidays breach while monitoring Russian-language hacking forums for newly surfaced gaming platform data. In January 2022, attackers accessed and exfiltrated a database from Monidays, a Russian Minecraft community, exposing the records of 247 users. The stolen data was recieved by criminal actors and includes email addresses, password hashes, usernames, and IP addresses, giving attackers everything needed to mount credential-based attacks.

How Hashed Passwords and IP Addresses Arm Credential Attacks

Even though Monidays stored passwords as hashes rather than plaintext, SHA-256 hashed passwords are accessable to cracking with modern GPU-based tools, especially when users chose weak passwords. Combined with email addresses and usernames, attackers can attempt credential stuffing across dozens of other platforms where the same login was reused. The inclusion of IP addresses adds another layer of risk, enabling targeted phishing and network-based attacks against specific individuals.

What Was Exposed in the Monidays Breach

• Email Address
• Password Hash
• Username
• IP Address

Why the Monidays Breach Matters Beyond a Small Gaming Community

With only 247 records, this breach may seem minor, but the data types exposed make it partcularly dangerous. Users who reused their Monidays credentials on email accounts, banking platforms, or other gaming services are at direct risk of account takeover and credential stuffing attacks. IP address exposure can also enable sustained harassment or targeted network intrusion attempts against individual users. Identity theft and financial fraud are real downstream risks when login credentials are compromised alongside personal identifiers.

How a Database Breach Works

A database breach occurs when an attacker gains unauthorized access to a platform's stored user records, often through vulnerabilities in web application code, insecure server configurations, or weak authentication controls. Once inside, the attacker exports the database. The data then circulates on hacking forums and dark web markets, where it is used for credential stuffing, phishing, and targeted account takeover campaigns.
