GoldenCloudFree Was Leaked in 2023. The Data Is Still Circulating.

HEROIC analysts identified a stealer log tied to GoldenCloudFree that was uploaded to Telegram in August 2023. The log exposed 19,215 records containing email addresses, plaintext passwords, and URLs harvested from compromised endpoints. Stealer logs of this type are assembled by malware running silently on infected devices, capturing credentials before users have any indication something is wrong. More than two years after the initial leak, this data remains accessible in dark web communities where it continues to fuel criminal activity.

Why the GoldenCloudFree Stealer Log Is Dangerous

Because the passwords in this log are in plaintext, attackers need no additional tools to use them. Anyone who downloads this data can immediately attempt to sign in to email accounts, cloud storage, banking portals, and social media platforms. The URLs included in the log give attackers a precise map of which services each victim was using at the time of infection, allowing them to prioritize high-value targets. With email addresses and matching passwords in hand, a criminal can launch automated login attempts across hundreds of services within minutes.

What Was Exposed in GoldenCloudFree

• Email addresses
• Plaintext passwords
• URLs (revealing which services and platforms victims were using)

Why This Matters

Plaintext password leaks are among the most immediately actionable types of breach data. Attackers use this information for credential stuffing, a technique where stolen username and password pairs are tested automatically against dozens of popular websites. Because many people reuse the same password across multiple accounts, a single credential pair from this log could unlock email inboxes, financial accounts, and personal profiles. Once an email account is compromised, attackers can reset passwords on every other service, leading to full account takeover. Victims may also face identity theft and financial fraud as attackers exploit the access they gain.

How Stealer Logs Like GoldenCloudFree Work

Infostealer malware is typically delivered through phishing emails, malicious software downloads, or compromised websites. Once installed on a device, it runs silently in the background, recording keystrokes, capturing passwords saved in browsers, and logging the URLs of sites the user visits. This harvested data is packaged into a log file and transmitted to the attacker. The logs are then sold or freely distributed on Telegram channels and dark web forums, where buyers use them for fraud, account takeover, and targeted phishing campaigns. The GoldenCloudFree log followed exactly this pattern, moving from an infected device to a Telegram upload in a matter of days.
