2K .UK Stealer Log Targets British Email Users: 1,673 Hit

HEROIC analysts identified a stealer log dump, labeled "2K .UK," posted to a Telegram channel on July 16, 2026. The file contains 1,673 records, each including an email address, a plaintext password, and the URL of the account the credential unlocks. The uploader's label points to a specific focus: this batch was curated around logins tied to .uk websites and accounts, suggesting the seller filtered a larger stealer log down to just the entries connected to UK-based services.

Why This Is Dangerous

Because the credentials in this file were harvested directly from infected devices, every password appears in plaintext alongside the exact email and URL it belongs to. That means an attacker does not need to crack or guess anything, they can simply pick a record and attempt to log in immediately. For a curated list like this one, an attacker interested specifically in UK accounts, whether for financial fraud, account takeover, or resale, gets a ready-made target list without having to sift through unrelated data first.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the websites where the credentials were used

Why This Matters

For the 1,673 people in this file, the immediate risk is unauthorized access to whatever account each password unlocks. If any of these individuals reused their password elsewhere, attackers can attempt credential stuffing against other services, including banking, email, and shopping sites, turning one exposed login into a broader case of identity theft or financial fraud. Because the log is filtered to .uk accounts specifically, it may also attract buyers looking to target UK residents in particular, such as through follow-up phishing attempts referencing UK-specific services.

How Stealer Logs Work

A stealer log is generated by infostealer malware that infects a device, often through a pirated download, cracked software, or malicious attachment, and then silently collects saved passwords, autofill entries, and browsing data from the victim's browser. Sellers frequently sort and repackage large stealer logs into smaller, targeted batches, such as this one focused on .uk accounts, to make the data more appealing to buyers with a specific interest. These curated files are then distributed through Telegram channels dedicated to trading stolen login data.
