Cloud Users Targeted in the 47,466 Record PIXELCLOUD2 Stealer Log Breach

In December 2025, HEROIC analysts identified a stealer log file uploaded to Telegram under the name 6550PCS_10.12.2025_PIXELCLOUD2. The file contained 47,466 records harvested from approximately 6,550 compromised machines in the United States, with data collected on or around December 10, 2025. Each record in the file included an email address, a plaintext password, and the URL of the site where those credentials were captured.

The PIXELCLOUD2 identifier in the filename suggests this is the second release from the same Telegram channel or operator. A second batch from the same source following a first indicates an active, ongoing campaign distributing fresh credentials on a regular schedule. Users of cloud-based platforms and online services were among those caught in this operation, given the "PixelCloud" branding associated with this distribution channel.

What the PIXELCLOUD2 Stealer Log Exposed

• Email addresses linked to active user accounts
• Plaintext passwords with no encryption or hashing applied
• URLs showing the exact services and platforms each credential belongs to

Why Cloud Platform Users Are Especially Vulnerable in This Breach

The PIXELCLOUD2 naming points to a focus on users of cloud-based services. These platforms often hold sensitive personal files, work documents, and connected app credentials. An attacker who gains acces to a cloud account through stolen credentials can access everything stored there, and often use it as a launchpad to compromise other connected services.

With plaintext passwords in hand and the matching URL already embedded in the log, an attacker does not need to guess which service to target. Credential stuffing can be performed immediately. If the same password was reused across email, storage, or finacial services, the damage multiplies from a single log entry. Account takeover, data theft, and identity fraud are the most common outcomes when credentials from logs like this are actively exploited.

How the 6550PCS_10.12.2025_PIXELCLOUD2 File Was Created

The "6550PCS" in the filename describes the approximate number of infected machines that contributed to this log. Stealer malware running on each of those devices silently read saved browser credentials, session data, and form-fill passwords before transmitting everything to the operator. All of that data was then consolidated into a single file and uploaded to Telegram for distribution.

The precise date stamp in the filename (10.12.2025) is unusuall for a stealer log and suggests the operator is organized enough to track and label batches by collection date. This level of organization points to a professionalized operation rather than a casual attacker, which means follow-up releases are likely and the data pipeline is probably still active.
