Researchers Link the PixelCloud2 816 Dump to 53,291 Stolen Credentials

HEROIC researchers linked a second PixelCloud2 stealer log package to a Telegram-based threat actor operating in January 2026. The file, dated 27.01.2026 and labelled batch 816, contained 53,291 records with email addresses, plaintext passwords, and URLs. This follows an earlier PixelCloud2 release from January 18 of the same year, confirming that PixelCloud2 is an ongoing infostealer distribution operation rather than a one-time upload -- the operator is systematically packaging and releasing credential batches on a regular schedule.

Why a Recurring Stealer Log Operation Like PixelCloud2 Is More Threatening Than a One-Time Breach

A single stealer log upload is troubling. A numbered, dated series of uploads points to an organized, persistent operation with infrastructure, a distribution channel, and an ongoing victim base. The batch number 816 and the precise date in the filename suggest this actor maintains a consistent pipeline for harvesting, packaging, and releasing credentials. Each new batch brings fresh plaintext passwords and current URLs, meaning the data is more likely to reflect active accounts with passwords that have not yet been changed. For victims in the January 27 batch specifically, the risk is immediate -- their credentials were current enough to be included in a release nine days after the previous batch.

What the PixelCloud2 27.01.2026 Stealer Log Exposed

The 53,291 records in this batch included:

• Email addresses (login identifiers for online accounts across many services)
• Plaintext passwords (unencrypted, captured directly from infected devices)
• URLs (the specific sites where each set of credentials was harvested)

As with the earlier PixelCloud2 batch, the three-field structure makes this dataset immediately usable for credential stuffing attacks without any additional processing.

Why the PixelCloud2 816 Batch Puts Accounts at Risk Across Multiple Services

Credentials from stealer logs like PixelCloud2 do not stay confined to a single attacker. Once uploaded to Telegram, a file like this gets downloaded, shared, and absorbed into larger combolists within hours. The freshness of the January 27 batch -- released just nine days after a previous PixelCloud2 package -- means these passwords are more likely to still be active than credentials from older breaches. Attackers who obtain this batch have a higher chance of finding logins that work. From there, the pattern is consistent: credential stuffing across email providers, banking apps, and social platforms, followed by account takeover, identity theft, and finacial fraud for any victims whose passwords remain unchanged.

How the PixelCloud2 Operation Packages and Releases Stealer Log Batches

The PixelCloud2 naming convention -- source name, date, batch number -- reflects a structured operation that processes infostealer output systematically. Infostealers distributed through phishing, fake software, or malicious browser extensions silently harvest credentials from victim devices. The operator aggregates this raw data, filters or organizes it into batches, and uploads regular releases to Telegram under a consistent naming scheme. The batch numbers and close date spacing between releases suggest a high-volume operation with a reliable distribution cadence.

Check If Your Credentials Were in the PixelCloud2 January 27 Batch

HEROIC indexes over 400 billion compromised records, including both PixelCloud2 batches and thousands of other stealer log packages. You can search your email address for free to find out if your credentials appeared in the January 27 release or any other dataset in our archive. If your email is found, change your passwords on every affected account imediately and prioritize any account where you reuse that password. Given that PixelCloud2 appears to be an active, ongoing operation, checking regularly is worthwile -- new batches may continue to surface.
