THOR V2 Logs Debut on Telegram: Next Generation of the THOR Stealer Series

In March 2023, an anonymous Telegram user uploaded THOR V2 Logs, a next-generation iteration of the THOR stealer series that exposed 3,357 endpoint records containing email addresses, URLs, API host data, and plaintext passwords. The release signaled a technical refresh of the THOR family and quickly circulated through criminal Telegram channels dedicated to stealer log distribution.

What Happened with the THOR V2 Logs Release

THOR V2 surfaced as a successor build to the original THOR stealer logs, uploaded to a public Telegram channel on March 2, 2023. Unlike previous dumps that bundled older harvests, THOR V2 introduced fresher captures and an updated format used by operators running the next-generation payload. The dump aligns with a wider trend of stealer families releasing versioned upgrades to bypass detection and maintain relevance in the underground marketplace.

Scope of the Exposure and Data Types

The THOR V2 Logs archive contains 3,357 individual records harvested from infected endpoints. Each record pairs an email address or username with a plaintext password and the associated URL or API host, giving attackers a ready-made credential set for account takeover campaigns. Because the logs originate from malware-infected devices rather than a single breached service, the exposed credentials span banking portals, email providers, workplace tools, and cloud consoles all at once.

Why Next-Generation Stealer Logs Raise the Stakes

Stealer-as-a-service operators iterate quickly, and a V2 release usually means improved evasion, faster exfiltration, and better data normalization for resellers. For defenders, that translates to shorter gaps between infection and credential abuse. Attackers can load the dump into automated checkers and hit dozens of services before victims know their session cookies or saved logins were siphoned from the browser.

What Individuals and Security Teams Should Do Now

If your credentials appear in THOR V2, rotate every password saved in the affected browser, revoke active sessions, and enable hardware-backed multi-factor authentication. Run a reputable anti-malware scan to remove the underlying infostealer, because stored passwords will continue leaking until the malware is eradicated. Organizations should feed the exposed list into their dark web monitoring pipeline and force resets on any matching corporate accounts.

Check Your Exposure with HEROIC

HEROIC maintains one of the largest breach intelligence databases on the planet with more than 400 billion records drawn from stealer logs, combolists, and historical data leaks. Search your email at HEROIC to confirm whether THOR V2 or any other dump has compromised your credentials, then lock down exposed accounts before attackers do.
