Your Passwords May Be in DAISY_CLOUD.part20 Telegram Stealer Log

HEROIC has processed the DAISY_CLOUD.part20 stealer log, the twentieth file in a systematic Telegram distribution series that released tens of thousands of stolen credentials throughout July 2023. This file contains 4,931 records including email addresses, plaintext passwords, and URLs captured from compromised devices. As the twentieth numbered installment, part20 confirms the DAISY_CLOUD operation was a sustained, organized credential harvesting campaign running at significant scale.

Why This Is Dangerous

By the time a numbered series reaches part20, the operation behind it has demonstrated persistence and volume, traits that distinguish professional threat actor groups from opportunistic criminals. The 4,931 credentials in this file are fully usable because they're stored in plaintext, and the URL data pinpoints exactly which platforms to target. Operations that run this long and this consistently often have buyers lined up before each batch even drops, meaning these credentials entered the threat ecosystem immediately upon upload.

What Was Leaked in the DAISY_CLOUD.part20 Breach

• 4,931 email addresses from infected endpoint devices
• Plaintext passwords captured directly from browser and application credential stores
• URLs identifying which services and accounts each victim was actively using

How the DAISY_CLOUD.part20 Data Could Be Used Against You

Your email address and password, paired with the URL of your bank or email provider, is everything an attacker needs for a silent account takeover. These credentials don't expire on their own. If you haven't changed your passwords since 2023, your credentials from this log remain fully valid today. Credential stuffing tools can run thousands of login attemps per hour across multiple services. Once an email account is compromised, attackers use it as a pivot point to reset credentials on every other platform you use, creating a cascading identty compromise that's difficult to stop and recover from.

Stealer Log Explained: The Attack Behind This Leak

The DAISY_CLOUD series ran to at least 20 parts in July 2023, suggesting the operator had access to a large pool of infected machines or was aggregating logs from multiple infostealer campaigns. Each part represents a batch of log files from different compromised devices. The malware responsible for generating these logs typically gets distributed through malvertizing, trojanized software, or phishing kits targeting high-traffic platforms. Victims never know their credentials were stolen unless someone notifies them or they find their accounts have been accessed. HEROIC indexes these distributions specifically to provide that notification before the damage occurs.
