Password Reusers Targeted in the 3,781-Record THOR Stealer Dump

HEROIC analysts identified a stealer log branded THOR FRESH LOGS, uploaded to Telegram on March 8, 2023, containing 3,781 stolen account records. The file included plaintext email and password pairs along with the URLs identifying each service the credentials belonged to, all harvested from infected devices.

Why the THOR Stealer Log Is Dangerous

Unlike a single-company breach, THOR pulls every saved password out of one infected browser at once, so a single victim can expose logins for dozens of unrelated sites. Anyone who reused passwords across accounts is at heightened risk, since one working credential from this dump can unlock several others.

What Was Exposed

• 3,781 email and password pairs stored in plaintext
• URLs identifying the exact service tied to each credential

Why This Matters

Because these passwords were harvested directly from browsers, they were confirmed working at the moment of collection. Criminals feed them into automated credential stuffing tools that test each pair against banking, email, and workplace logins, leading to account takeover, financial fraud, and identity theft for anyone caught in the dump.

How the THOR Stealer Log Was Created

THOR-family malware spreads through cracked software, phishing attachments, and malicious ads. Once it runs on a victim's device, it scans saved browser logins, packages the results, and sends them to the operator, who bundles the data into fresh log releases sold on Telegram.
