Check If DAISY_CLOUD Stealer Log Exposed Your Password

HEROIC researchers have confirmed a stealer log breach known as DAISY_CLOUD, uploaded to Telegram in July 2023 by an anonymous threat actor. The leak exposed 4,736 records containing email addresses, plaintext passwords, and URLs harvested from infected endpoints. This stealer log dataset is part of a growing wave of credential theft that bypasses traditional security measures entirely by capturing data directly from victims machines before any encryption can protect it.

What makes this particular breach so dangrous is the combination of plaintext passwords paired directly with email addresses and the URLs where those credentials were used. Attackers don't need to crack anything, they already have full working login pairs. Anyone whose credentials appear in this dataset is at immediate risk of account takeover across every service where they reused that password.

Inside the DAISY_CLOUD Leak: Data Categories Exposed

• Email Addresses: Full email addresses tied to real user accounts, usable for phishing and account recovery attacks
• Plaintext Passwords: Passwords captured in cleartext directly from browser or application memory, no cracking required
• URLs: The exact website addresses where credentials were harvested, giving attackers precise targeting information for each victim

Why the DAISY_CLOUD Breach Is a Credential Stuffing Risk

Stealer logs like DAISY_CLOUD feed directly into automated credential stuffing operations. Here is how the fraud chain typically unfolds after a dump like this hits underground markets:

• The log file gets parsed and cleaned into a ready-to-use combo list of email:password pairs
• Threat actors load those combos into tools like Snipr or OpenBullet and hammer login pages across banking, retail, and email services
• Successful logins get sold or used for account draining, fraudulent purchases, or identity theft
• Secondary accounts linked to the compromised email (social media, cloud storage, work logins) also fall into attacker hands through password reuse or account recovery chains
• The orignal victim often has no idea anything happened until fraudulent charges or lockouts appear

How Stealer Log Data Gets Into Criminal Hands

Stealer logs don't come from server hacks. They come from malware that runs silently on a victim's own device. Information stealers like Redline, Raccoon, and Vidar are typically delivered through phishing emails, cracked software downloads, or malicious ads. Once installed, the malware sweeps the machine for saved browser credentials, active session cookies, autofill data, and crypto wallets before transmitting everything to a remote command-and-control server. Operators then compile the harvested records into log files and distribute them through private Telegram channels, dark web forums, or sell them to other criminal groups. The DAISY_CLOUD channel is one of many such distribution pipelines that cycle through millions of stolen records every month. By the time a log file is publicly uploaded, the credentials it contains have often already been exploited mulitple times.
