What Attackers Can Do With The IggyCloud Leak’s 30.8M Logins

HEROIC analysts uncovered one of the largest stealer logs tracked this year, "IggyCloudV1 1," posted to Telegram in November 2025. The file contains 30,789,992 records, each pairing a stolen email address with its plaintext password and the URL of the account it unlocks. At nearly 31 million entries, it ranks among the biggest single stealer logs HEROIC has reviewed.

What Attackers Can Do With The IggyCloud Leak

With almost 31 million working logins in one file, an attacker does not need to target anyone specifically. They can run automated scripts that attempt every email and password pair against major banks, email providers, and shopping sites within hours.

Because each record already includes the matching website, there is no research or setup required. Attackers can move straight from downloading the file to logging into real accounts.

What Was Exposed In The IggyCloud File

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why 30.8 Million Exposed Logins Matter

A leak of this size feeds credential stuffing at massive scale, quietly testing stolen passwords across thousands of sites until reused combinations succeed. Anyone who shares a password between accounts is especially exposed, since one compromised login can unlock several others.

The fallout regularly includes account takeover, identity theft, and financial fraud, often affecting people who have no idea there computer was ever infected in the first place.

How A Stealer Log This Size Gets Assembled

Infostealer malware spreads through pirated software, cracked games, and phishing links, then quietly harvests saved browser passwords and session data from each infected device. A file the size of IggyCloud is typically built by combining results from a huge number of seperate infections over weeks or months.

Once assembled, these massive logs are shared on Telegram to attract buyers, who then use or resell the data in smaller, targeted batches to other criminals.
