OXLOADER Leverages Google Ads and Storj to Deploy CastleStealer with CIS Exclusions

OXLOADER uses verified Google ads and Storj to push CastleStealer via UAC abuse and DLL side-loading, with deliberate CIS exclusions and heavy obfuscation. The campaign exposes routine software searches as high-risk vectors for credential theft. Low detection rates and ties to prior GrayBravo operations indicate sustained operational maturity.

Expect rapid iteration on staging techniques and possible expansion beyond Google Ads to other search providers unless Storj abuse triggers platform-level blocks.

⚡ Prediction

Elastic Security: OXLOADER detections will exceed 40% across public sandboxes by September 2026.
