HEROIC's DarkHive system discovered the NEW DAISYCLOUD Mar 4 stealer log, exposing 15,786 records on March 4, 2024. A Telegram user uploaded this infostealer malware log harvested from 728 compromised U.S. endpoints, containing email addresses, plaintext passwords, and service URLs. The March 4 release is the earliest known drop in the DAISYCLOUD March 2024 series, marking the start of a two-week daily credential distribution campaign.


Why This Is Dangerous

As the apparent opening release of the March 2024 DAISYCLOUD series, the March 4 drop established the pattern for a two-week campaign that would expose hundreds of thousands of U.S. credentials in total. The 728 infected devices each contributed an average of 21.7 stored credentials, providing subscribers with a diverse set of account types spanning the full range of websites visited by affected users. Plaintext passwords are immediately usable without any cracking, and the included service URLs allow attackers to target specific platforms rather than running broad spray-and-pray campaigns. The freshness of an opening series release means credentials had not yet been tested by competing attackers.


What Was Exposed

  • Email addresses
  • Plaintext passwords
  • Service and API host URLs

Why This Matters

Daily credential releases like the DAISYCLOUD March series create a compounding threat where each new drop adds to the total pool of exploitable accounts. The freshness of credentials from early-series releases is especially valuable to attackers because victims are less likely to have rotated passwords or detected the compromise. Organizations whose employees' devices were infected during the March 4 campaign face exposure of corporate credentials, VPN logins, and cloud platform access alongside personal accounts captured on the same endpoint.


How Stealer Log Works

Infostealer malware is deployed through phishing emails, malicious downloads, and fake software update prompts. Once running on a victim's device, the malware silently extracts saved credentials from browser storage, password manager integrations, and application sessions before transmitting the data to attacker-controlled servers. The DAISY CLOUD [NEW] operator packages the collected records into daily log files labeled with the harvest date and device count and releases them on Telegram, where subscribers download and begin exploiting the credentials within hours. Victims rarely know their credentials were harvested until suspicious account activity is detected.
