Day Two: DaisyCloud-Championing Posts 16,238 U.S. Credentials on May 4

On May 4, 2024, the NEW_DAISYCLOUD-CHAMPIONING Telegram channel released 16,238 sets of U.S. infostealer credentials -- the second day of a documented 18-day consecutive run that extended through May 20. At 16,238 records, this is the lowest single-day total in the early portion of the documented series -- but it is still a substancial release that placed tens of thousands of U.S. credential sets into the hands of Telegram subscribers. The following days would see volumes climb back above 25,000 before the campaign reached its peak of 54,210 on May 10.


DaisyCloud-Championing May 4, 2024: Breach Summary

  • Records Exposed: 16,238
  • Data Types: Email addresses, plaintext passwords, target login URLs
  • Breach Type: Infostealer malware log
  • Country Affected: United States
  • Date Leaked: May 4, 2024

Why Even Lower-Volume Days Still Matter

In the context of a campaign where single-day releases reached 54,210 records, the May 4 total of 16,238 can appear unremarkble. But perspective matters: 16,238 individual U.S. credential sets -- each containing a plaintext email address, a plaintext password, and the exact URL where those credentials are used -- is a meaningful exposure event by any standard. If even a fraction of those records were exploited in account takeover attacks, the impact could extend to financial accounts, corporate systems, or personal data. The lower volume of May 4 doesn't diminish the per-record threat; it simply means fewer individuals were exposed on this particuarly day compared to higher-volume releases.


Building Toward the Peak

The four-day opening window of the campaign -- May 3 (26,129), May 4 (16,238), May 5 (28,455), May 6 (25,333) -- shows the operator distributing consistently in the 16,000-28,000 range before the pre-peak escalation on May 7 (26,937) and May 8 (31,343) and ultimatly the 54,210-record apex on May 10. This early-series baseline demonstrates the campaign was not building from nothing: even before reaching its peak, NEW_DAISYCLOUD-CHAMPIONING was releasing tens of thousands of U.S. credentials per day, every day, without pause.
