LeakBase 8M ULP by RandomD Contains 1,826,606 Exposed Email Pairs

On October 3, 2024, a stealer log titled 8M ULP was posted to LeakBase by threat actor RandomD, containing exactly 8 million raw records. Deduplication confirms 1,826,606 unique email-and-password pairs, each accompanied by a homepage URL. All passwords are stored in plaintext, removing any barrier to immediate exploitation. The structure of the dataset points to aggregated infostealer output from multiple compromised endpoints rather than a breach of a single organization's database.

Why This Is Dangerous

A dump of 1.8 million plaintext credential pairs is a ready-made toolkit for credential stuffing. Attackers can begin probing accounts within hours of acquiring this data, focusing on high-value targets like banking, email, and payment platforms where password reuse is most damaging. The homepage URL data adds targeting context, allowing attackers to prioritize victims whose URLs reveal high-value service affiliations.

What Was Exposed

• Email addresses (1,826,606 unique)
• Plaintext passwords — zero decryption required, directly usable
• HomePage URLs — mapping victim services and online footprints

Why This Matters

• Credential stuffing: 1.8 million plaintext pairs give attackers high-volume ammunition for automated login attacks across banking, retail, and communication platforms.
• Account takeover: Compromised email credentials unlock password resets for every linked service — banking, cloud storage, social media — in a single step.
• Identity theft: Access to a victim's primary email exposes years of personal communications, documents, and financial records.
• Targeted fraud: HomePage URLs reveal the exact services a victim uses, enabling precision attacks rather than broad spray-and-pray campaigns.

How Stealer Log Breaches Work

Infostealer malware reaches victims through phishing emails, trojanized software downloads, or compromised browser extensions. Once executing on a device, it silently extracts every credential saved in the browser's password manager, along with session tokens and autofill fields, then transmits the harvest to the attacker's server. The attacker compiles infections from many victims into consolidated ULP (URL-Login-Password) logs and posts them on forums like LeakBase, either for direct use or sale to other threat actors. Most victims do not discover the compromise until they receive account-takeover alerts from their email or bank.
