12,434 Passwords Leaked in ‘standart 1137’ Stealer Dump

In May 2026, a stealer log file named "standart 1137 pcs 29.4.26" was uploaded to Telegram by an anonymous user. The dump held 12,434 records pulled straight from compromised devices, each containing an email address, a plaintext password, and the URL of the site the credentials belonged to.

Why This Is Dangerous

The name attached to this file is just a label a threat actor gave their own log dump. It is not the name of a company that was hacked. What matters is what's inside: live, unencrypted passwords tied to real login pages, which is about as usable as stolen data gets for a criminal.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the matching login pages

Why This Matters

Plaintext passwords paired with URLs let attackers skip the guesswork. They can automate login attempts across banking, email, and shopping sites in minutes, a tactic called credential stuffing. Anyone who reused one of these passwords elsewhere faces a real risk of account takeover, identity theft, and financial fraud.

How Stealer Log Dumps Like This Get Made

Infostealer malware is usually the source. It spreads through cracked software, fake installers, or malicious email attachments, then quietly harvests every password saved in a victim's browser along with autofill data and session cookies. The stolen data gets bundled into a file, given an arbitrary name like "standart 1137 pcs 29.4.26," and passed around Telegram channels or sold on dark web marketplaces.

Check If You Are Affected

Because these logs get renamed, split, and resold constantly, you cannot rely on recognizing a company name to know if you are exposed. HEROIC's free breach scanner searches your email against more than 400 billion compromised records, including stealer logs like this one. Check your exposure for free and take action before your credentials are used against you.
