Breaking Update – June 20, 2025

Latest developments from ongoing investigation reveal the true scope and impact of this unprecedented breach.

Executive Summary

Cybersecurity researchers have uncovered a massive data breach containing over 16 billion stolen credentials across 30 exposed datasets. This breach, discovered by Cybernews security experts in collaboration with researcher Bob Diachenko and Aras Nazarovas, represents one of the largest credential exposures in history, affecting users of major platforms including Apple, Telegram, Facebook, Google, GitHub, Zoom, Twitch, and countless other services.

Critical Update: Security expert Bob Diachenko confirms that while there was no centralized breach at major companies like Facebook, Google, or Apple, the leaked datasets contain login credentials that provide pathways to these services through infostealer malware operations.

What Happened: The Largest Credential Breach in History

The Scale of the Breach – Updated Statistics

The discovered datasets contain:

• 16 billion total credentials across 30 separate databases
• 3.5 billion records in the largest single dataset (Portuguese-speaking population)
• 455 million Russian credentials specifically exposed
• 184 million records in what Wired magazine called a “mysterious database”
• 60 million Telegram accounts specifically targeted
• 16+ million records in the smallest identified dataset
• 550 million records average per dataset
• 30 different databases with varying levels of overlap

How These Credentials Were Stolen – Enhanced Analysis

The exposed data originates from sophisticated infostealer malware operations that represent a significant shift in cybercriminal tactics. According to Cybernews researcher Aras Nazarovas, this discovery signals that criminals are abandoning previously popular methods:

“The increased number of exposed infostealer datasets in the form of centralized, traditional databases may be a sign that cybercriminals are actively shifting from previously popular alternatives such as Telegram groups, which were previously the go-to place for obtaining data collected by infostealer malware.”

How Infostealers Operate:

• Deploy through pirated software downloads
• Hide in infected PDF files
• Masquerade as game modifications
• Spread via malicious email attachments
• “Exfiltrate everything” including:
  • VPN credentials
  • Authentication session cookies
  • Email login credentials
  • Internal development tools
  • Stored documents and browsing history
  • Autofill data

Each dataset typically contains three critical pieces of information:

1. Website URL (login page pathway)
2. Username/email address
3. Password

Data Structure and Accessibility – New Insights

Critical Finding: Most datasets were exposed only briefly through:

• Unsecured Elasticsearch instances
• Unprotected object storage systems
• Temporary database exposures

The brief exposure window means researchers discovered them before widespread criminal exploitation, but the structure and recency of the data makes it particularly dangerous.

Why This Breach Matters More Than Others

The Sophistication Factor – Updated Analysis

This breach demonstrates an evolution in cybercriminal operations beyond simple attacks to coordinated, large-scale data harvesting. The sheer volume of 16 billion credentials creates unprecedented risks:

Cross-platform vulnerability: Stolen credentials provide pathways to virtually any online service Automated attack potential: Large datasets enable sophisticated bot-driven login attempts Phishing scheme fuel: Criminals can create highly targeted campaigns using real user data Fresh intelligence: This isn’t recycled old breach data – it’s recent, weaponizable information

Industries and Platforms Affected – Comprehensive List

Based on the latest analysis, the breach impacts:

Enhanced Security Insights from Security Experts

Expert Analysis from Bob Diachenko

Security researcher Bob Diachenko, who unveiled this breach, clarifies a crucial point:

“There was no centralized data breach at any of these companies. Credentials we’ve seen in infostealer logs contained login URLs to Apple, Facebook, and Google login pages.”

This means the breach provides pathways to access major services rather than indicating direct breaches of those companies’ systems.

Advanced Threat Intelligence from Aras Nazarovas

Cybernews researcher Aras Nazarovas warns about sophisticated evasion techniques:

“Some of the exposed datasets included information such as cookies and session tokens, which makes the mitigation of such exposure more difficult. These cookies can often be used to bypass 2FA methods, and not all services reset these cookies after changing the account password.”
