UNC5142 EtherHiding WordPress stealer campaign
Campaign
Summary
Hide ▲
Show ▼
The UNC5142 campaign is abusing compromised WordPress sites and BNB Smart Chain smart contracts to deliver information stealers to Windows and macOS users, making the delivery chain harder to disrupt. By routing payload retrieval through EtherHiding and multi-stage loaders, the operation can change infrastructure without rewriting code on the infected sites. Google flagged about 14,000 web pages tied to the activity by June 2025, showing broad abuse of vulnerable sites. The campaign had not been seen since July 23, 2025, suggesting either a pause or an operational pivot.
