April 9: The Series Extends Into the First Week of April

The documented scope of the NEW_DAISYCLOUD-CHAMPIONING campaign continues to grow. The 21,775 U.S. infostealer credentials released on April 9, 2024 push the confirmed series into the first full week of April. While specific dates within this early-April period continue to be verified, the April 9 release confirms that the channel's output was active well before the mid-April dates that were initialy associated with the start of the series.


NEW_DAISYCLOUD-CHAMPIONING April 9, 2024: Breach Summary

  • Records Exposed: 21,775
  • Data Types: Email addresses, plaintext passwords, target login URLs
  • Breach Type: Infostealer malware log
  • Country Affected: United States
  • Date Leaked: April 9, 2024

21,775 Records: Early-April Volume Consistent With Peak Period

The 21,775 records released on April 9 are not a warm-up number. They are consistent with the channel's output during its documented peak weeks in May. This consistency across months -- nearly the same volume in early April as in mid-May -- tells a clear story about the operation's infrastucture. The malware network feeding NEW_DAISYCLOUD-CHAMPIONING was not a small or newly launched operation in April. It was a mature system that had been infecting U.S. devices and accumulating credentials for an extended period before the first confirmed Telegram release.


The Challenge of Documenting Early-Month Releases

Documenting infostealer campaigns that span multiple weeks and months is technicaly challenging. Telegram archives are not permanenly maintained, and some early uploads may be inaccessible or unindexed by the time researchers begin systematicly examining a channel's history. The April 9 release has been confirmed through direct data examination -- but the full picture of every individual day in early April is still being establshd from available records. What is clear is that the campaign was activley distributing U.S. credentials in early April 2024, and the total scope of its output remains substancial regardless of how many individual dates are ultimately confirmd.
