80,000 Passwords Exposed Now: Logs_1 December Telegram Breach

In December 2025, HEROIC detected a massive stealer log file shared on Telegram under the name "Logs_1 December," exposing 80,056 records. The file was distributed by an anonymous Telegram user and contained plaintext passwords, email addresses, and URLs harvested from infected devices by infostealer malware. At over 80,000 victims, this is one of the larger single Telegram stealer log drops in recent months, and the December 2025 date means the data is extremely fresh.

Fresh stealer log data is uniquely dangerous. These aren't old credentials that users may have already rotated. They are current logins pulled from active devices during recent browsing sessions. Attackers act quickly on new drops — within hours of a file going public, automated tools are already testing credentials across dozens of platforms. If you were in this breach and haven't changed your passwords, you are still at risk right now.

What Logs_1 December uploaded by a Telegram User Leaked: The Full Data Picture

• Email Addresses — used to link victims to their accounts across every platform they're registered on
• Plaintext Passwords — unencrypted credentials that attackers can use without any additonal processing
• URLs — the specific pages where logins were captured, showing which services and accounts were active

Why Logs_1 December uploaded by a Telegram User Data Creates Lasting Identity Risk

Being in this breach puts you at risk across every account where you've reused a password. Here is how:

Credential stuffing attacks are automated and fast. Bots test thousands of stolen login pairs per minute against banking portals, email accounts, streaming services, and social media platforms. There is no manual effort required from the attacker — your credentials get tested everywhere automatically.

Password reuse turns one breach into total exposure. Most people reuse passwords. Attackers know this and systematically test stolen credentials on high-value targets first — email providers, banks, and cloud storage. One leaked password can give them access to your entire digital life.

Phishing attacks become surgical with URL data. Knowing which services you use lets attackers build convincing fake messages in the exact style of those services. Victims who recieve these emails often can't tell the difference from the real thing.

How Stealer Log Attacks Harvest Login Data

Stealer log breaches like this one begin on individual computers. Infostealer malware infects a victim's device — delivered through phishing emails, malicious software downloads, fake game cracks, or drive-by browser exploits. Once installed, the malware runs silently in the background, recording every credential entered into a browser, copying saved passwords, stealing session cookies, and logging visited URLs.

Everything collected gets bundled into a log file and transmitted back to the attacker's command server. These logs are then distributed on Telegram channels by operators who sometimes release small sample batches publicly to attract buyers for larger paid collections. The victims have no indication their machine was infected, and no warning that their credentials are now circulating online. This particular December 2025 drop of 80,056 records represents thousands of real people whose accounts are actively at risk.
