Private MIX 26.04 Part 4: 2,999 Plaintext Passwords Leaked

On 13 May 2026, a Telegram user uploaded "Private MIX 26.04 Part 4," a stealer log file containing 2,999 stolen login records, the fourth installment in an ongoing series. The file pairs email addresses with plaintext passwords and the URLs where each password was captured, the standard format for credentials harvested straight from infected computers rather than stolen in a breach of any single website.

Why "Part 4" Signals an Ongoing Operation

The "Part 4" label is the detail that matters most here. It means whoever compiled this file has already released at least three earlier batches under the same "Private MIX 26.04" series, and at nearly 3,000 records, this installment is substantial. A numbered, recurring series like this points to a steady pipeline of infected devices feeding new credentials into the collection month after month.

What Was Exposed in Part 4 of the Series

• Email addresses
• Plaintext passwords
• URLs showing which site each password logs into

Why Nearly 3,000 Exposed Logins Is a Serious Risk

Because the passwords are stored in plaintext and matched to exact login URLs, attackers can use them immediately, without cracking anything. At this volume, the file is a ready-made toolkit for credential stuffing across banking, retail, and social platforms. Anyone whose details appear here faces a real risk of account takeover, identity theft, and financial fraud, especially if the same password is reused anywhere else.

How a Numbered Stealer Log Series Like This Is Built

Series like "Private MIX 26.04" come from infostealer malware that infects victims' devices, quietly extracts saved browser logins, autofill data, and session details, and sends them to whoever controls the malware. That operator then packages the haul into numbered parts, releasing "Part 4" once enough new credentials had accumulated, and shares each file through Telegram channels where other criminals buy or trade access.
