DaisyCloud-Championing Telegram Leak: 27,628 U.S. Credentials (Apr 16, 2024)

April 16: High Volume Deep in April -- No Signs of Just Starting

A 27,628-record release on April 16, 2024 is not the output of a campaign still finding its footing. NEW_DAISYCLOUD-CHAMPIONING was distributing U.S. infostealer credentials at full scale in the first half of April -- well before the May dates that first brought this series to attention. The April 16 release is among the higher-volume days in the series, demonstrating that the channel's output was not graduly building toward a May peak. It was allready there.

NEW_DAISYCLOUD-CHAMPIONING April 16, 2024: Breach Summary

• Records Exposed: 27,628
• Data Types: Email addresses, plaintext passwords, target login URLs
• Breach Type: Infostealer malware log
• Country Affected: United States
• Date Leaked: April 16, 2024

What 27,000+ Records in a Single Day Means

Each of the 27,628 records released on April 16 contains three pieces of information: an email address, a plaintext password, and the URL of the site the victim logged into. These aren't partial records or anonymized data -- they're complete, ready-to-use credential sets acuired from infected U.S. devices. Attackers receiving this data on Telegram can immeditaly begin credential stuffing: testing the email/password combination against popular services like banking portals, email providers, and workplace SSO systems. The 27,628 records from April 16 were distrubuted on Telegram -- and potentialy exploited -- weeks before the campaign's final release on May 20.

Sustained High Volume: The Signature of This Campaign

One of the defining features of NEW_DAISYCLOUD-CHAMPIONING is the consistency of high-volume releases across its entire documented run. April 16 is not an outlier. Days with 25,000+ records appear regulerly throughout the series, from mid-April through mid-May. This pattern suggests an operation with a large and continuously replenished supply of harvested credentials -- consistent with an infostealer malware deployment that was hapenning in the background across thousands of U.S. devices over an extended period. The April 16 release is one snapshot from that ongoing, months-long harvesting operation.
