The TOR_LOG MIX 309PCS Stealer Log Was Uploaded in May 2024. The Data Is Still Circulating.

HEROIC analysts identified the TOR_LOG MIX 309PCS stealer log file when it was uploaded to a public Telegram channel in May 2024 by an anonymous user. The dump contains 5,731 exposed records captured directly from infected endpoint devices by infostealer malware. Each record includes an email address, a plaintext password, and one or more URLs identifying the services and websites the victim was accessing at the time of infection. The file was posted publicly on Telegram -- meaning the moment it went live, it became accessible to every threat actor monitoring those channels. The data has had over a year to be downloaded, copied, traded, and used in credential stuffing attacks across every platform represented in the log.

Why the TOR_LOG MIX 309PCS Leak Is Dangerous

Time does not make a stolen credential less dangerous -- it makes it more dangerous. A plaintext password leaked in May 2024 that has never been changed is just as usable today as it was the day the file was posted. The 5,731 records in this dump include complete email-password pairs with no hashing or encryption to slow an attacker down. Every combination works on first try. The TOR_LOG naming convention indicates these logs were collected through a network that routes traffic through anonymizing infrastructure, making it harder to trace the attacker's identity or origin. The URLs embedded in each record tell attackers exactly which platforms each victim used -- banking, email, social media, cloud storage -- allowing precise, targeted exploitation rather than blind credential stuffing across random services.

What Was Exposed

• Email addresses
• Plaintext passwords (no encryption or hashing)
• URLs linked to accessed websites and services
• API host information from compromised endpoints
• Endpoint device metadata

Why This Matters for You

The TOR_LOG MIX 309PCS upload happened over a year ago. In that time, these credentials have had the opportunity to be sold privately, shared across multiple underground forums, included in aggregated combo lists, and used in automated account takeover campaigns against every major platform on the internet. Victims almost never recieve any notification -- no breach letter, no email alert -- because no company database was hacked. The malware stole the data directly from the victim's device, bypassing every server-side protection the affected services had in place. If your email and password appear in this log and that password has not been changed since mid-2024, the window for preventive action is not closed, but it is narrow. Seperate accounts where the same password was reused are particularly at risk.

How Stealer Log Malware Works

TOR_LOG MIX 309PCS is the output of infostealer malware -- a class of credential-harvesting software designed to be invisible, fast, and thorough. Infection typically begins with something that looks completely legitimate: a software installer, a browser extension, a game mod, or an email attachment. Once the malicious code executes, it immediatley begins scanning the device for every stored password it can find. It hits browser password stores first -- Chrome, Firefox, Edge, Brave -- extracting every saved login. It then targets email clients, FTP tools, cryptocurrency wallets, and any other applications that store authentication data. Session cookies are captured as well, allowing attackers to bypass two-factor authentication on active sessions. The entire harvest is packaged into a structured log file and transmitted to the attacker's server. The whole process can occured in under three minutes from the moment of infection. The malware then removes traces of itself, and the victim's device continues functioning normally. The resulting log is then shared on Telegram channels under names like TOR_LOG MIX.
