A file called aviron_links exposed a massive 4,190,719 stolen credential records from a February 12, 2026 stealer infection.

Why This Is Dangerous

Once hackers have over 4 million plaintext passwords in hand, they don't need to manually check anything, automated tools can test every single login against hundreds of popular websites within hours.

What Was Exposed

• Email addresses (4,190,719 unique accounts)
• Plaintext passwords with no encryption
• URLs tied to each compromised service

Why This Matters

A file this size, over 4 million records, represents one of the larger individual stealer logs tracked this year. Hackers with access to this data can run large-scale credential stuffing campaigns targeting banks, email providers, and shopping sites simultaneously.

How Stealer Logs Work

Stealer malware behind operations like aviron_links infects devices at scale, quietly copying saved browser passwords before sending everything back to the operator. Building a file with over 4 million records takes a sustained infection campaign running for weeks or months, wich explains the sheer size of this particular release.
