Someone Could Log Into Your Account: pengelan123.com Leak

In June 2026, HEROIC analysts found a stealer log tied to pengelan123.com uploaded to Telegram by a threat actor. The file contained 517 records made up of email addresses, plaintext passwords, and the URLs those credentials were used on.

Why This pengelan123.com Stealer Log Is Dangerous

Picture someone taking one line from this file: an email address, a plaintext password, and the exact web page it opens. They do not need to guess or crack anything, they can simply type it in and be logged into that account within seconds. That is the level of access this leak hands to whoever has a copy of it.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

Because each password is matched to its exact login page, attackers can go straight to account takeover on the 517 accounts in this log. If any of these passwords were reused on other sites, such as email, banking, or shopping accounts, credential stuffing tools let attackers test that same password across many unrelated services, so the damage can reach well beyond the accounts named here.

How Stealer Logs Work

Stealer logs come from malware that infects a device and quietly copies saved browser passwords, autofill entries, and the web addresses tied to them, then sends everything back to the attacker. Because the theft happens on the victim's own computer rather than a hacked company server, the stolen credentials are often still valid when the log surfaces on Telegram.
