Researchers Link the logs 31dec v2 Dump to 11,005 Stolen Credentials on Telegram

HEROIC analysts detected the upload of a file called logs 31dec v2 to a public Telegram channel on January 2, 2024. The file was shared by an anonymous user and contained 11,005 records pulled from compromised endpoints. Each record included an email address, a plaintext password, and a URL indicating which service the infected user had been accessing. The label on the file suggests the data was harvested on or around December 31, 2023, before being packaged and posted to Telegram two days later.

Why This Is Dangerous

Stealer log files with plaintext passwords give attackers an immediate attack surface. There is nothing to decode or reverse engineer. Every credential in this file can be tested against live accounts the moment an attacker downloads the file. With email addresses and associated service URLs also present, criminals know exactly where to direct their efforts, reducing the time between download and successful account breach to minutes.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (services and login portals accessed by victims)

Why This Matters

The 11,005 stolen credentials in this file are the fuel for credential stuffing campaigns that target banking apps, cloud accounts, and retail platforms. Because most people use the same password across multiple accounts, a single leaked login can compromise a dozen services at once. Victims also face ongoing risk from phishing operations, since their email addresses are now confirmed active and atached to real service accounts. This kind of data rarely stays in one place. It gets reshared, sold, and reused for months or even years.

How Stealer Log Leaks Work

Researchers have linked stealer log dumps like this one to infostealer malware families that spread through phishing attachments, fake software cracks, and compromised websites. Once installed, the malware harvests passwords from browsers, captures login activity, and records the URLs of services visited. These logs are then collected by the malware operator, bundled into files, and distributed through Telegram channels where other criminals can acces them freely. The entire cycle from infection to public distribution can happen in less than 24 hours.
