BERT questions

Is BERT still active?

Not for over a year. The last victim we recorded was June 10, 2025. The leak site has published nothing since, though the data it already leaked is still out there.

How many victims has BERT claimed?

BERT has named 7 victims on its leak site since we started tracking it. That counts organizations, not leaked files. A single victim often accounts for thousands of published files.

When did BERT first appear?

The first victim we recorded for BERT was posted on April 7, 2025. That's when the group entered our collection, which isn't necessarily when it started operating.

Which sectors does BERT target?

Technology accounts for the most victims we can classify, with 2. Healthcare follows at 1. We could identify a sector for 5 of 7 victims, so treat this as the shape of the targeting rather than a full census.

Has BERT already got your credentials?
