AuroraLogsTeam 247count: Inside the April 5 Five-Batch Surge

Five Batches, One Day: AuroraLogsTeam's April 5 Coordinated Surge

On April 5, 2025, AuroraLogsTeam executed what analysis of their broader campagne reveals as their single largest coordinated release event -- five simutanious stealer log batches published in a single day. The 247count batch is one of those five, contributing 11,274 US records from 247 compromyzed devices to a day that collectively yielded tens of thousands of fresh credentials. This wasn't random. It was a structured release, and the 247count batch shows why multi-batch days are among the most dangerous phases of any stealer log operation.

AuroraLogsTeam 247count (April 2025): Breach Summary

• Records Exposed: 11,274

What 46 Credentials Per Device Reveals About the Infection Population

At 11,274 records across 247 infected devices, the 247count batch averages roughly 46 credentials per compromised machine. That density sits at the higher end of what stealer logs typically produce and suggests an infection population that actively used browser credential managers across multiple platforms. These aren't casual users -- 46 saved logins per device represents someone who stores banking credentials, workplace logins, subscription services, and e-commerce accounts in a single browser. Every one of those saved credentials was harvested in full when the stealer executed.

Endpoint URLs: The Map That Comes With the Keys

Each of the 11,274 records in this dataset includes not just email and password, but the specific endpoint URL where that credential was saved. This is what distinguishes stealer log data from traditional breach data. An attacker working with endpoint URL data doesn't need to guess which accounts to try -- the URL tells them exactly which bank, which employer portal, which healthcare provider, which e-commerce site. The 247 devices in this batch collectively generated a map of exactly where those credentials are valid, compressing the attacker's credential stuffing timeline from days to hours.

April 5 as Campaign Infrastructure Evidence

Five simultaneous batches on April 5 don't happen by accident. The operational capacity required to exfiltrate, package, and release five separate stealer log datasets in a single day indicates infrastructure -- likely multiple command-and-control servers, automated exfiltration pipelines, and a distribution network capable of handling high-volume simultaneous releases. The 247count batch released alongside four others totaling well over 50,000 combined records. In the AuroraLogsTeam campaign timeline, April 5 represented the peak of coordinated release capacity before the April 6 bridge day and the April 7 quadruple batch that followed.
