Telegram Users Beware: T.ME NIGHT_CLOUD_FREE Dumped 3,226 Accounts

HEROIC analysts identified the T.ME NIGHT_CLOUD_FREE stealer log on December 17, 2022, when it surfaced on the Telegram channel operating under the NIGHT_CLOUD_FREE handle. The upload contained 3,226 records pairing email addresses with plaintext passwords and the URLs of the services where those credentials were active. The targeted nature of this log -- small in volume, specific in structure -- suggests victims were selected or harvested from a defined pool of users rather than swept up in a broad automated campaign. HEROIC analysts noted the log's direct usability as a key risk factor at the time of discovery.

Why This Is Dangerous

Every record in the NIGHT_CLOUD_FREE log contains three pieces of information an attacker needs to compromise an account: the login email, the password in plaintext, and the URL of the service being targeted. There is no additional work required on the attacker's side. Unlike hashed password leaks that require cracking before use, this data is immediately operational. At 3,226 records, the entire dataset can be tested manually or with basic automation in a very short timeframe. Victims who reuse passwords across services face compounded risk, since a single exposed credential can unlock multiple accounts across different platforms.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the specific services where credentials were valid)

Why This Matters

Stealer log data fuels some of the most effectve cyberattacks currently active. Credential stuffing tools take lists like this one and automatically test each email and password pair against hundreds of online platforms. A single successful match can lead to complete account takeover -- and from a compromised account, attackers can initiate password resets on connected services, access stored payment methods, and harvest personal information used for identity theft. For victims in this log, the exposure has been active since December 2022, meaning their credentials have had years of potential circulation. Financial fraud and unauthorized access to personal accounts remain live risks for anyone who has not yet rotated their passwords.

How Stealer Logs Work

Infostealers are a class of malware that run silently on infected devices and harvest credentials before the user ever notices anything wrong. Victims are most commonly infected through phishing links, fake software cracks, or malicous browser extensions. Once active, the malware accesses the password vaults built into browsers like Chrome and Edge, reads any saved login data, and captures credentials as they are typed into web forms. The collected records are packaged into a structured log file and sent back to the attacker's server. Operators then sell these logs on dark web forums or distribute them freely on Telegram channels -- as happened here -- to build a following or trade for other stolen data. The term "stealer log" refers to this output file, and a single infected device can produce dozens of credential records.

Check If You Are Affected

If your credentials appeared in the T.ME NIGHT_CLOUD_FREE stealer log, your email and password have potentially been accessible to attackers since 2022. HEROIC's breach search database indexes over 400 billion records from thousands of breach events and stealer log dumps. Visit heroic.com to search your email address and see wether your data appears in this or any other known breach. Updating your passwords and enabling two-factor authentication are the most immediate steps you can take to protect your accounts.
