DAISY_CLOUD February 26: 103 Infected Devices, 1,409 U.S. Login Records Stolen

103 Infected Computers. One Telegram Upload. 1,409 U.S. Logins Exposed.

The "103 PCS" in the file name isn't a product count. It's the number of compromised endpoints: 103 individual computers that had infostealer malware running on them when this log was assembled. Each machine contributed its stolen credentials to the DAISY_CLOUD February 26 dump, which totaled 1,409 U.S. records by the time it hit Telegram. That's roughly 14 credential pairs per infected device, a typical yield for this category of stealer operation.

HEROIC's DarkHive team flagged the upload, confirmed the data, and documented it as a verified breach on February 26, 2023. What's in the file is straightforward but dangerous: email addresses, plaintext passwords, and the exact URLs where those credentials were captured.

DAISY_CLOUD as an Operation: Dated, Organized, Ongoing

DAISY_CLOUD appears to be a naming convention used by a specific threat actor or malware operation. Multiple dated drops from this source have been observed across different days in February 2023, each labeled with a date and piece count. The pattern, releasing logs in batches with specific metadata, suggests an organized distribution operation rather than a one-off incident. The February 26 release exposed:

• Email Addresses: 1,409 U.S. accounts
• Plaintext Passwords: Captured in cleartext directly from infected browsers
• Target URLs: Exact login pages tied to each credential set

The dated batch structure also means the data is fresh when it reaches Telegram. Unlike old database dumps that sit dormant for months before leaking, stealer logs from recent collections represent accounts that are definitly still active. Victims haven't changed their passwords yet because they don't know they're compromized.

Small Dataset, Real Consequences for the People Inside It

A file of 1,409 records won't generate mainstream headlines. But the people in this dump face identical risks to victims in much larger breaches. Credential stuffing attacks don't require scale to succeed: they require valid credentials. And since the passwords here are plaintext and the target URLs are included, an attacker can begin testing these logins within minutes of downloading the file.

For anyone in this dump, the exposure chain looks like this: their primary email may be accessible, any service where they reused that password is at risk, and if a work login was captured by the infostealer, corporate systems could be exposed through one infected home device. That's the pratical reality of how stealer logs translate into downstream damage.

HEROIC Tracks DAISY_CLOUD and the Broader Stealer Log Ecosystem

The DarkHive team indexes stealer log data from Telegram and underground channels into HEROIC's breach database, now covering more than 400 billion records. Their free breach scanner checks any email instantly against this dataset. If your credentials appeared in the DAISY_CLOUD dumps or any related breach, you'll see it. Knowing is the first step. Changing your passwords before an attacker uses them is the second.
