Algeria Corp Telegram Leak: 1,058 Plaintext Passwords Exposed

HEROIC analysts identified a stealer log file uploaded to a Telegram channel in February 2026. The file, labeled "ALGERIA CORP-OTHERS-PRO MAILS TEST SAMPLE," contained 1,058 records of stolen credentials. The leaked data includes email addresses, plaintext passwords, and the specific URLs where those credentials were used.

Why This Stealer Log Is Dangerous

Every record in this leak contains a working email and password combination stored in plaintext. Attackers do not need to crack or decode anything. They can copy these credentials directly into login pages and gain immediate access to accounts. Because the leak also includes the specific URLs tied to each credential, attackers know exactly which services to target first.

Stealer log data is prized by cybercriminals because it represents real, recently active credentials harvested directly from infected devices. Unlike older database breaches, these passwords were captured at the moment of use, making them far more likely to still work.

What Was Exposed in This Leak

• Email Addresses - Login identifiers used across multiple online platforms
• Plaintext Passwords - Fully readable passwords requiring zero decryption to exploit
• URLs - The specific websites and services where these credentials were entered

Why This Matters for Your Accounts

If you reuse the same password across multiple accounts, a single exposed credential from this leak can unlock your email, banking, social media, and other sensitive services. Attackers routinely feed stolen credentials into automated tools that test username and password pairs against hundreds of popular platforms within minutes. This technique, called credential stuffing, turns one leaked password into a skeleton key for your entire digital life.

With email addresses and passwords in hand, criminals can also launch targeted phishing campaigns, reset passwords on connected accounts, and commit identity theft. The plaintext format of these passwords means there is absolutely no barrier between the leaked data and full account takeover.

How Stealer Logs Harvest Your Credentials

Stealer logs come from malware known as infostealers. These programs silently infect computers and mobile devices through malicious downloads, fake software updates, or phishing links. Once installed, the malware monitors browser activity and captures every username, password, and URL entered into login forms.

The stolen data is packaged into log files and sent back to the attacker. These logs are then sold or shared on platforms like Telegram, where other criminals buy them in bulk. Each log represents a real person's credentials, stolen from their actual browsing sessions on their own device.
