Change Your Password: Expertlogs Breach Exposed 138,361 Accounts

HEROIC researchers found 138,361 records on 19-Jun-2025 from Expertlogs 2400, a large stealer log drop posted to the t.me Expertlogs Telegram channel.

Why This Stealer Log Is Dangerous

Expertlogs 2400 is a six-figure credential dump that pairs every email with a plaintext password and the exact URL it unlocks. At 138,361 records, it is large enough to power broad credential stuffing against banks, email providers, crypto exchanges, and enterprise SaaS. Because the passwords are not hashed, any attacker who downloads the file can start logging into victim accounts within minutes.

What Was Exposed in Expertlogs 2400

• Email addresses
• Plaintext passwords
• Login URLs and API host endpoints
• Active session and application context from infected machines
• Device and browser metadata tied to each compromised account

Why This Matters

The Expertlogs Telegram channel has been a recurring distribution point for high-volume stealer logs, and drop number 2400 is one of its largest. For affected users, the immediate risk is account takeover on whatever service the URL field points to, followed by credential reuse attacks against personal email, banking, and corporate SSO. Changing any password that appears in the drop is the single most urgent action.

How a Stealer Log Like Expertlogs 2400 Works

Infostealers such as RedLine, Raccoon, Lumma, and Vidar infect devices through cracked software, fake installers, malicious ads, and phishing. Once resident, the malware extracts saved browser credentials, cookies, autofill data, and wallet files, then exfiltrates everything to the operator. Operators package the output into numbered drops like Expertlogs 2400 and post them to Telegram channels, where buyers replay the credentials at scale.
