Warning: UP_DaisyCloud 5k Logs June 1 Exposes 89,663 Passwords

HEROIC analysts recovered 89,663 records from the Telegram UP_DaisyCloud 5k Logs June 1 by .boxed.pw on June 1, 2025. The stealer log contains email addresses, plaintext passwords, and homepage URLs harvested by infostealer malware from compromised machines across the United States.

Why the UP_DaisyCloud Leak Is Dangerous

Consider this a public warning. Nearly 90,000 usable logins sit in a single Telegram file, with no encryption standing between a scroller and your inbox. Each row includes the exact URL the password unlocks, which compresses the time between download and exploitation to seconds.

What Was Exposed in the UP_DaisyCloud Dump

• Email addresses
• Plaintext passwords
• HomePage URLs matched to each credential
• IP addresses and system details from infected machines

Why This Matters

89,663 live credentials are prime ammunition for credential stuffing, account takeover, identity theft, and fraud. Stealer logs capture every site a browser stored, so one infected device can burn email, cloud, banking, and workplace accounts in the same sweep. Reused passwords extend the damage into services that never appeared in the log.

How Stealer Logs Work

Infostealer malware such as RedLine, Lumma, and StealC spreads through cracked software, fake installers, malicious ads, and phishing attachments. Once active, it reads saved browser passwords, cookies, and autofill entries, then uploads the haul to an operator. Operators package the stolen data into dated logs and post them to Telegram channels like .boxed.pw for fraud crews to grab within hours.

Check If You Are Affected

Search your email in HEROIC's breach scanner, which indexes more than 400 billion records including fresh Telegram stealer logs. If you match, rotate every reused password, run a full malware scan on the affected device, and enable multi-factor authentication on email, banking, and work accounts.
