JS#SMUGGLER Uses Compromised Sites to Deploy NetSupport RAT
🔍 Securonix has detailed a campaign named JS#SMUGGLER that leverages compromised websites and an obfuscated JavaScript loader to deliver the NetSupport RAT. Attackers chain a hidden iframe and a remote HTA executed via mshta.exe to run encrypted PowerShell stagers and fetch the RAT. The loader applies device-aware branching and a visit-tracking mechanism to trigger payloads only on first visits, reducing detection risk. Temporary stagers are removed and payloads execute in-memory to minimize forensic artifacts.
