DaisyCloud Stealer Log: 11,553 Endpoint and Email Credentials Leaked (2024)

Stealer Logs, Telegram Channels, and the New Shape of Credential Theft

Not all credential exposures come from traditional database breaches. Information-stealing malware -- stealers -- operate differently: they infect endpoint devices, harvest credentials from browsers, apps, and saved passwords, and exfiltrate everything to a command-and-control server. The data is then packaged and distributed through underground channels, primarily Telegram. In June 2024, a stealer log file containing 11,553 records of endpoint credentials, email addresses, plaintext passwords, and URLs was uploaded to a Telegram channel -- data associated with the DaisyCloud platform and its connected infrastucture.

DaisyCloud Stealer Log (June 2024): Breach Summary

• Records Exposed: 11,553
• Data Types: Email addresses, plaintext passwords, URLs (endpoint/API credentials)
• Breach Type: Stealer log
• Country Affected: United States
• Date Leaked: June 21, 2024

What Stealer Logs Contain That Database Breaches Don't

Traditional database breaches expose whatever was stored in a platform's user table: typically email addresses and password hashes. Stealer logs expose what was active on a compromised device at the time of infection: browser-saved credentials (which are often plaintext), session cookies, API keys, endpoint URLs, autofill data, and environment variables. The DaisyCloud stealer log includes URLs alongside email addresses and plaintext passwords -- indicating not just user credentials but the specific endpoints and API hosts those credentials were used to authenticate against. This is a more complete picture of a victim's digital access than a database breach typicaly provides.

Telegram as a Breach Distribution Channel

The upload of stealer logs to Telegram channels has become a primary distribution mechanism for credential data. Telegram's relative anonymity, large group capacity, and bot infrastructure make it well-suited for automated credential distribution. Channels dedicated to stealer log sharing operate semi-openly, with subscribers receiving regular updates of freshly harvested credentials from infected endpoints worldwide. The June 21, 2024 DaisyCloud upload represents one file in a continuous stream of similar material -- a reminder that credential exposure is not a discrete event but an ongoin ecosystem of theft, aggregaton, and redistribution.

Two Sequential DaisyCloud Uploads: A Pattern Worth Noting

This June 21 stealer log was not an isolated event. A companion upload the previous day (June 20, 2024) exposed 17,069 records from the same DaisyCloud-related infrastructure. Two consecutive daily uploads from the same named source suggest either an ongoing systematic exfiltration campaign targeting DaisyCloud-connected endpoints, or a batch distribution of previously collected data being released in parts. Either interpretation points to a deliberate and organized operation rather than a one-off opportunistic infection.
