IFF Assessment
FOE
This is bad news for defenders as it highlights a new, complex attack chain combining known information stealers with advanced persistent threats.
Defender Context
Defenders should be aware of this combined threat, as Lumma Stealer is known for stealing credentials and sensitive data, while RATs provide deep system access. Monitoring for the initial Lumma Stealer infection and subsequent lateral movement or persistence attempts by Sectop RAT is crucial.
