How the datacloudspace Stealer Log Led to 13,479 Stolen Logins

In August 2023, HEROIC analysts identified a stealer log posted to Telegram under the name 1226 logs datacloudspace. Uploaded by an anonymous Telegram user, this collection contains 13,479 records, each including an email address, a plaintext password, and the URL of the service where the credential was stolen. The "1226" designation in the name likely refers to the number of individual log bundles packaged together, meaning this dataset aggregates credentials from over a thousand separate device infections into a single distributable file.

Why the datacloudspace Stealer Log Is Dangerous

At 13,479 records, this is one of the larger stealer log releases in this series, and size matters. Larger datasets give attackers more targets to work through in credential stuffing campaigns, increasing the overall probability that at least some of the pairs will unlock active accounts on high-value services. Every credential is plaintext, every email address is a confirmed username, and every URL is a direct pointer to a service the victim was using at the time of infection. This makes the datacloudspace log a comprehensive toolkit for automated account takeover.

What Was Exposed in datacloudspace

• Email addresses
• Plaintext passwords
• URLs (the specific services and websites each credential is tied to)

Why This Matters

Datasets of this size are the backbone of large-scale credential stuffing campaigns. When over 13,000 plaintext email and password pairs are available on Telegram, attackers can distribute them across multiple botnet nodes and test thousands of login attempts per second against banking sites, email platforms, retail accounts, and corporate portals. A single successful login can cascade: email access leads to password resets on linked accounts, and one compromised corporate credential can open doors into sensitive internal systems. Identity theft, financial fraud, and unauthorized data access are all plausible outcomes from a single credential in this log.

How Stealer Logs Like datacloudspace Work

The datacloudspace log is the output of infostealer malware campaigns run across a large number of infected devices. Infostealers are distributed through phishing emails, trojanized software downloads, fake browser extension updates, and malicious ad networks. Each infected device runs the malware silently, extracting saved passwords from browsers, capturing login credentials in real time, and recording the associated URL for every set of data collected.

Individual device logs are then aggregated by the operator, cleaned, and bundled into packages for distribution. The "datacloudspace" branding represents the Telegram channel or operator behind this specific collection. Releasing 1,226 bundled logs at once demonstrates a sustained, organized collection operation rather than a one-time incident. This level of scale and organization is typical of professionalized infostealer groups that treat credential harvesting as a recurring business.

Check If You Are Affected

HEROIC maintains a breach intelligence database of more than 400 billion records, including stealer logs like this one. Run a free scan to see if your email address or credentials appear in the datacloudspace dataset. With 13,479 records in active circulation, identifying your exposure now is the most direct way to protect your accounts before attackers act on the data.
