One Telegram Upload. 2,706 Cloud Credentials. The Alaska Cloud Free Stealer Log.

HEROIC analysts came across this upload in late October 2023 while reviewing a Telegram channel regularly used to distribute stealer log files. The file, posted on October 23, 2023, contained 2,706 records associated with Alaska Cloud Free, a cloud-based service. While the record count is relatively small compared to other stealer log dumps, what caught our attention was the nature of the data. These were not generic login pages. The exposed URLs and API host entries pointed at cloud infrastructure, which suggests that whoever the malware infected had access to systems worth targeting specificaly.

Why This Is Dangerous

Cloud credential leaks carry a different kind of risk than standard account breaches. When an attacker gets hold of credentials tied to cloud infrastructure, they can potentially access storage buckets, spin up compute resources, extract databases, or move lateraly through connected systems. The presence of API host information in this dump makes it even more actionable. An attacker does not need to explore or probe, the endpoint is right there in the log. And because all passwords are in plaintext, there is no technical barrier between the file and a successful login attempt.

What Was Exposed

• 2,706 total records
• Email addresses linked to Alaska Cloud Free accounts
• Plaintext passwords (fully unencrypted)
• Cloud endpoint URLs pointing to active infrastructure
• API host information for targeted systems
• Leak first appeared on Telegram on October 23, 2023

Why This Matters

Small-volume stealer logs are sometimes dismissed as low-priority incidents, but that logic breaks down when the exposed data touches cloud systems. A single set of valid cloud credentials can give an attacker far more leverage than thousands of regular user accounts. Organizations using Alaska Cloud Free should treat this leak as a direct threat to their infrastructure, not just an abstract data privacy concern. Credential rotation, multi-factor authentication, and active monitoring for unusual login activity are all relevant responses to a dump like this one.

How Stealer Logs Work

Stealer malware typically arrives through phishing emails, drive-by downloads, or malicious browser extensions. Once installed on a victim's machine, it scans for saved passwords in browsers, credential files, and any locally stored configuration data. It then packages everithing into a structured log file and sends it out. Telegram has become a popular delivery mechanism because it allows attackers to distribute files quickly and without much traceability. The Alaska Cloud Free log was part of this exact pipeline, collected from infected endpoints and uploaded to a channel where it could be freely downloaded by anyone with access.
