TGCloudLogsis 4: 7,956 Passwords Exposed. Yours Might Be One.

TGCloudLogsis 4: 7,956 Stolen Credentials Exposed on Telegram in 2023

In August 2023, HEROIC analysts identified a stealer log file distributed on Telegram under the name TGCloudLogsis 4. The file exposed 7,956 records harvested from infected U.S. endpoints, each containing an email address, a plaintext password, and the URL of the service the credential was stolen from. TGCloudLogsis 4 is one entry in a numbered series, indicating an organized distribution operation that packaged and released stolen credentials in batches.

These records were taken from real people's computers by malware operating silently in the background. The victims had no idea their credentials were being harvested, and most still don't know unless they've checked a breach scanner.

Why 7,956 Plaintext Passwords Should Concern You

Plaintext passwords are the most immediately dangerous form of stolen credential. There is no encryption to defeat, no hash to crack, no extra step required. An attacker downloads the file, finds an email address they recognize or care about, and uses the password directly. The time from acquisition to account access can be measured in seconds.

With 7,956 records, the TGCloudLogsis 4 dump is not the largest stealer log in circulation, but every single record in it is a complete, ready-to-use login package. Size matters less than usability, and this data is highly usable. If any of those passwords are still active on the accounts they were taken from, the owner is at risk right now.

What Was Exposed in the TGCloudLogsis 4 File

• Email Addresses: Full account login emails for all 7,956 records
• Plaintext Passwords: Unencrypted passwords, readable and usable without any additional tools
• URLs: The exact services and websites each credential belongs to

Why This Data Is Still Relevant in 2026

The TGCloudLogsis 4 dump is from 2023, but that does not make it irrelevant. Stealer log data has a long shelf life because password change behavior is poor. Studies consistently show that most people do not change their passwords unless forced to, and very few people are even aware their credentials were taken in a stealer log incident.

Attackers actively recycle older dumps in credential stuffing campaigns, knowing that a meaningfull percentage of the credentials are still valid. A 2023 stealer log tested against major platforms in 2026 will still produce successful logins for accounts that have never been updated. Those accounts are then used for fraud, spam, identity theft, or sold on to other operators.

How TGCloudLogsis Stealer Logs Are Produced

The TGCloudLogsis series is a Telegram-distributed stealer log operation. The underlying credentials are collected by info-stealer malware, a type of software designed to run invisibly on a victim's device and extract saved passwords, cookies, and autofill data from the browser. Once collected, this data is organized into log files and distributed through Telegram channels.

The numbered naming convention, TGCloudLogsis 1, 2, 3, 4, and so on, suggests a channel that publishes batches on a regular schedule. Subscribers to these channels recieve the logs without paying, either as free samples to build trust or as part of a free-tier offering to attract users to a paid service. Each release reaches an uncontrolled number of recipients, making it impossible to track how widely any given dump has been distributed.

Because stealer malware runs on the victim's device rather than attacking a company's server, there is no data breach notification and no corporate disclosure. The only indication a victim might get is finding their email in a breach scanner result.
