The Colombia 4 Leak Exposed 2,595 Emails and Passwords Online

HEROIC analysts identified a stealer log dataset labeled "Colombia 4," uploaded to a Telegram channel on February 24, 2023. The file contains 2,595 records made up of email addresses, plaintext passwords, and the URLs of the sites those credentials were used on.

Why This Is Dangerous

Because this data was harvested directly by malware rather than pulled from a hacked database, every password in the file sits in plaintext, paired with the exact email address and website it belongs to. An attacker doesn't need to crack or guess anything. They can take the credential pair straight from the file and attempt to log in immediately.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials were used on

Why This Matters

With plaintext passwords tied to specific login pages, the 2,595 people in this dataset face immediate risk of account takeover on those exact services. If any of them reused their password on other accounts, such as email, banking, or social media, attackers can attempt credential stuffing to test the same login across other platforms, extending the damage beyond the original site.

How Stealer Logs Work

Stealer logs are produced by infostealer malware that infects a device through common channels like phishing emails, pirated software, or fake downloads. Once active, the malware quietly collects saved passwords, autofill data, and active browser sessions, then bundles everything into a single log file. Files like "Colombia 4" are then shared through platforms such as Telegram, where they can be downloaded and used by anyone within minutes.

Check If You Are Affected

Even smaller leaks like this one can expose working login credentials. HEROIC's free breach scanner checks your email against a database of more than 400 billion exposed records, giving you a fast, clear answer and steps to secure your accounts if you're affected.
