The 640K Private VPN Target Base Leaked in 2023. It Is Still Active.

HEROIC analysts identified a stealer log file named 640K Private VPN Target Base, uploaded by a Telegram user back in April 2023. The file contains 638,945 records pulled directly from infected devices, including email addresses, plaintext passwords, and the URLs those credentials unlock, many tied to VPN and privacy service accounts.

Why This Is Dangerous

This file has been sitting on Telegram for years, quietly available to anyone who wants it. The data was not stolen from a company's servers, it was captured by malware running on victims' own computers, copying saved browser passwords straight from the source. Because it targets VPN accounts specifically, an attacker who gets hold of it may be able to access services people use specifically to protect their privacy, which is a particularly uncomfortable irony.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each login, including VPN service accounts

Why This Matters

Even years after the original upload, a file like this keeps circulating and keeps causing damage. Attackers pull credential lists like this one and test them against email providers, banking sites, and other accounts through credential stuffing, since so many people reuse the same password everywhere. Anyone caught up in this leak faces an ongoing risk of account takeover, financial fraud, or identity theft, long after the initial breach happened.

How Stealer Logs Work

Stealer log malware spreads through pirated software, fake VPN installers, or malicious downloads disguised as legitimate tools. Once running on a device, it quietly copies saved passwords and autofill data out of the browser and bundles it into a text file. These files, like this VPN-focused dump, are then sold or shared on Telegram channels and dark web forums, sometimes for years after the original infection. Because the data was accurate at the time it was captured, some of these credentials may still work if the victim never changed their password.
