Your Passwords May Be in the Logs_29 November Telegram Breach

HEROIC analysts reviewed a stealer log batch uploaded to Telegram in November 2025 under the label "Logs_29 November" that exposed 80,354 records from infected endpoints in the United States. The collection contained email addresses, plaintext passwords, and the URLs where each set of credentials was harvested -- making this one of the larger single-batch stealer releases tracked that month. The date-stamped naming convention suggests this was part of a regular distribution schedule used by the threat actor to push fresh logs to subscribers.

For anyone whose device was infected during the period this campaign was active, the consequences are immediate and direct. Saved browser passwords, active login sessions, and the full list of sites the user visited were all fair game for this type of malware. With 80,354 records in circulation on Telegram, the risk window opened the moment the file was posted -- and it remains open indefinitely, as these datasets are shared, resold, and reused across multiple criminal operations for years after initial distribution.

What Data the Logs_29 November Breach Exposed

• Email Addresses -- Primary account identifiers exposing victims across all their online services
• Plaintext Passwords -- Cleartext, immediately operational passwords requiring no decoding
• URLs -- Site-level data revealing which specific services each victim's credentials belong to
• Endpoint Metadata -- Device information from each infected machine in the batch

The Path From Logs_29 November Breach to Account Fraud

The credential stuffing pipeline starts the moment a log file like this one hits Telegram. Automated tools ingest the 80,354 email and password pairs and begin systematically testing them against login forms at banks, email providers, streaming platforms, and workplace applications. Studies consistently show that roughly 0.5 to 2 percent of stuffed credentials produce successful logins -- meaning this single release could have enabled hundreds of unauthorized account accesses.

Identity theft risk is amplified by the URL field. Attackers who see that a victim was authenticated to a healthcare system, a government portal, or a financial application at the time of infection can prioritize those accounts for takeover. Access to email accounts is especially damaging because it allows attackers to trigger password resets across every other service, effectively locking the real owner out while gaining full control. Most victims of these attacks go weeks or months without realizing their accounts have been compromised.

Stealer Log Attacks: A Plain-English Explainer

Stealer malware doesn't need to break into a company's database to steal your passwords -- it breaks into your computer. These programs are typically disguised as free software downloads, pirated games, fake productivity tools, or maliciuos browser extensions. Once installed, the malware operates invisibly in the background, scanning the browser for saved login credentials, copying session cookies that keep you logged in without a password, and recording which websites you are actively using.

All of that harvested data gets assembled into a structured log file and silently transmitted to the attacker. Batches like "Logs_29 November" are then distributed through Telegram channels, where they attract buyers ranging from low-level fraudsters to organized crime groups. The date in the name tells potential buyers the logs are fresh, which commands higher prices in underground marketplaces. Freshness matters because people change passwords after they suspect a breach, so recently stolen crendentials are more likely to still work.
