Identity Theft Risk Rises: HUNTER_ULP Stealer Log Exposes 2.4M Records

HEROIC analysts identified a stealer log dump uploaded by a Telegram user in January 2026 that exposed 2,435,354 records. The dataset, distributed under the label HUNTER_ULP PREMIUM NEW UNRAPPED DATABASE 01-12-2025 14, contained email addresses, plaintext passwords, and URLs harvested from infected endpoint devices. The data was circulated through underground Telegram channels, making it widely accessible to threat actors within hours of publication.

Why This Stealer Log Is an Immediate Threat to Your Accounts

Stealer logs are not hashed or encoded -- they capture credentials exactley as they were typed or stored on a victim's machine. When attackers have plaintext passwords paired with email addresses and the exact URLs where those credentials were used, they can log directly into those accounts with zero effort. This combination also tells criminals which services a person uses, allowing them to sequence attacks across banking, email, and social platforms with surgical precision.

Data Exposed in the HUNTER_ULP Telegram Stealer Log Dump

The following categories of personal and authentication data were confirmed present in this breach:

• Email Addresses -- primary identifiers used to reset passwords and access linked accounts
• Plaintext Passwords -- unencrypted, ready-to-use login credentials with no cracking required
• URLs -- the specific websites and services where credentials were stolen, enabling targeted account takeover

How Criminals Weaponize Stealer Log Credentials

With this combination of data, cybercriminals pursue several high-value attack chains:

• Credential stuffing -- automated tools test the stolen email and password pairs against dozens of popular platforms simultaneously
• Account takeover -- direct login to the exact service identified by the stolen URL, often within minutes of obtaining the data
• Identity theft -- email account access allows attackers to reset passwords, intercept verification codes, and impersonate victims
• Financial fraud -- banking and payment URLs in the dataset point attackers directly to financial accounts ready to be drained
• Password spray pivoting -- since many users repete passwords, one valid credential opens doors across unrelated services

What Is a Stealer Log and How Does It End Up on Telegram?

Stealer logs are produced by information-stealing malware -- software secretly installed on a victim's computer, often through phishing emails, fake software downloads, or malicious browser extensions. Once active, the malware silently captures everything typed into login forms, saved passwords in browsers, session cookies, and the URLs associated with each credential. The resulting log files are then packaged and sold or freely distributed by threat actors on dark web forums and increasingly on Telegram, where the lack of oversight makes distribution fast and near-anonymous. The HUNTER_ULP naming convention is common among resellers who bundle multiple stealer log sources into premium datasets marketed to credential buyers.
