Online Services Breach: 9.8 LOGS_CENTER Stealer Log Hits 4,978 Accounts

HEROIC analysts discovered a stealer log file publicly posted to a Telegram channel on September 8, 2023. The dataset, labeled "9.8 - LOGS_CENTER," contained 4,978 records harvested from infected endpoint devices. Each record paired an email address with a plaintext password and the URL of the service it belonged to, suggesting broad infection across consumer and buisness accounts alike. The file was freely available for download, making it immediately usable by any threat actor who found it.

Why This Is Dangerous

Plaintext passwords require zero effort to exploit. Anyone who downloaded this log could begin attempting logins the same day. Because the records include the specific URLs the passwords belong to, attackers do not even need to guess which services to target. Corporate email accounts, financial platforms, and cloud-based buisness tools are all at risk when employee credentials show up in stealer logs like this one.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the services the passwords were used on)

Why This Matters

Stealer log credentials are recycled across multiple attack types:

• Credential stuffing: Automated tools test these email and password pairs against dozens of websites simultaneously.
• Account takeover: A compromised email account lets attackers reset passwords for banking, payroll, or cloud services.
• Identity theft: Personal information accessed through taken-over accounts is used to open fraudulent credit lines or loans.
• Financial fraud: Direct access to online banking or payment platforms leads to immediate theft.

How Stealer Logs Work

A stealer log is the output of infostealer malware. When a device gets infected, the malware runs quietly in the background and records every login the user makes. It captures the website address, the email or username, and the password before they are encrypted by the browser. These captured entries are bundled into a text file called a log, then sent back to the attacker. Logs are often sorted, cleaned, and redistributed on Telegram channels and dark web markets. The "LOGS_CENTER" name in this breach likely refers to the Telegram channel or service used to distrabute these files.
