Telegram Stealer Log 153: 2,833 Plaintext Credentials and URLs Leaked

Incident Overview

In March 2023, a Telegram user uploaded stealer log 153, exposing 2,833 credential records captured from endpoints running information-stealing malware. The archive included plaintext passwords, associated email addresses, and the complete login URLs where each credential was originally entered, giving attackers a precise roadmap into every victim's online accounts.

What Was Exposed

• 2,833 endpoint credential records
• Email addresses and usernames
• Plaintext passwords from browser-saved stores
• Login URLs and API host references
• Session cookies and authentication tokens

The Volume Problem in Modern Stealer Logs

While 2,833 records may sound modest, stealer logs like 153 are typically bundled with dozens of similar drops released across Telegram channels every single day. Aggregators scrape these feeds and assemble combo lists that run into the hundreds of millions of records. Volume is the entire point: credential-stuffing success rates are fractional, so attackers rely on sheer quantity to find the reused passwords that unlock high-value accounts.

Cookie Theft Bypasses Password Changes

Log 153 almost certainly includes the browser cookies that accompany captured credentials. When attackers import a victim's session cookie into their own browser, the target service treats them as already authenticated. This means password resets alone will not evict the attacker; users must actively sign out of all sessions and revoke cookies through each platform's security settings.

Action Plan After a Stealer Log Leak

• Use each service's "sign out everywhere" feature to invalidate cookies
• Rotate passwords after the source device is confirmed clean
• Enable hardware-key MFA on email, banking, and cloud accounts
• Remove saved browser credentials and migrate to a password manager
• Scan for persistent infostealer infections using a reputable EDR tool
