One Telegram Upload. One Log File. The ALPHACLOUDFREELogs2023-07-18X38M Breach Had 7,084 Stolen Credentials.

In July 2023, HEROIC analysts identified a stealer log file shared on Telegram under the identifier ALPHACLOUDFREELogs2023-07-18X38M 1. The file contained 7,084 records extracted from infected devices, with each record containing an email address, a plaintext password, and the URL of the site where the credentials were harvested. The breach follows a pattern HEROIC sees regularly: malware quietly running on a device, siphoning off saved credentials, and delivering them to a threat actor who then publishes the results openly online.

Why Plaintext Passwords Make This Immediately Dangerous

Most large database breaches expose hashed passwords, which require time and computing power to crack. This stealer log is different. Every single password in the ALPHACLOUDFREELogs file is in plaintext, meaning any attacker who downloads it can read them directly with no technical skill required.

The attached URLs tell attackers exactly which services each password belongs to. That eliminates the guesswork entirely. Rather than trying a password across hundreds of sites, an attacker already knows where it works. This is one of the most efficient forms of stolen credential data available on the dark web.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the specific login pages where credentials were captured)

Why This Matters for Account Security

When your email and password are both in a stealer log, you are at immediate risk of account takeover. Attackers running credential stuffing tools can test your credentials across dozens of platforms in seconds. If you use the same password on multiple sites, a single entry in this log could unlock your email, your bank account, your social media, and more.

Phishing is another concern. Once your email address appears in a known breach, it gets added to targeting lists used for future attacks. You might recieve a message that appears to come from a service you use, designed to capture additional information or push malware onto your device. Identity theft and financial fraud are common end results when stealer log data is actively exploited.

How This Type of Stealer Log Gets Created

The ALPHACLOUD log format is associated with infostealer malware distributed through Telegram-based malware-as-a-service operations. A threat actor pays for access to a stealer builder, customizes it, and distributes it through phishing campaigns or bundled with pirated software. The malware installs silently, scrapes browser-saved credentials, and transmits everything back to a collection server.

The resulting logs are then sorted, packaged, and uploaded to public Telegram channels. This particular file was timestamped and labeled with the ALPHACLOUD identifier, a naming convention used by several Telegram-based credential marketplaces. Once posted, the data is available to anyone who joins the channel, with no vetting or payment required.

Check If Your Credentials Were Stolen

HEROIC's free breach scanner searches a database of over 400 billion records, including stealer log files like this one. Enter your email address and see immediately whether your credentials have been compromised in any known breach or data leak.

If your data was included in the ALPHACLOUDFREELogs file or any similar leak, the scanner will tell you exactly what was exposed so you can take action. Checking takes less than a minute and could definately prevent a serious account takeover down the line.
