Identity Theft Just Got Easier: The 157 Stealer Log Put 2,187 at Risk

HEROIC identified 2,187 records on March 6, 2023, in a file called 157, a stealer log uploaded by a Telegram user. The dataset contained email addresses, plaintext passwords, and URLs pulled from infected browsers, and every record shortens the distance between a leaked login and full identity theft.

Why the 157 Stealer Log Is Dangerous

Identity theft is hardest when attackers have to guess. The 157 file removes that barrier. With a working email, the attached password, and the specific login page, criminals can walk straight into mailboxes, banking portals, and tax accounts and start assembling the pieces of a full identity profile.

What Was Exposed in the 157 File

• 2,187 stealer log records captured from infected machines
• Email addresses tied to personal and professional identities
• Plaintext passwords with zero encryption or hashing
• URLs revealing which services each password unlocks
• Evidence that the victim devices were running infostealer malware

Why This Matters for Identity Theft Risk

Once the 157 credentials circulate, attackers use them to take over email inboxes, intercept password reset links, and raid financial accounts. From there it is a short walk to opening lines of credit, filing fraudulent tax returns, and standing up synthetic identities. A single reused password in this file can trigger months of recovery work and lasting credit damage.

How a Stealer Log Like 157 Works

Infostealer malware, including RedLine, Raccoon, Vidar, and Lumma, gets onto a computer through cracked apps, fake installers, or phishing attachments. Once it runs, it reads saved browser credentials, autofill data, cookies, and crypto wallet files, then uploads the haul. Operators bundle the captures into files like 157 and drop them into Telegram channels and dark web forums, where buyers mine them for identity theft leads.

Check If You Are Affected

HEROIC maintains more than 400 billion compromised records across its breach intelligence database, including stealer logs like 157.
