AZORult has its history. However, a few days ago, we discovered what appears to be one of its most unusual campaigns: abusing the ProtonVPN service and dropping malware via fake ProtonVPN installers for Windows.

The campaign started at the end of November 2019 when the threat actor behind it registered a new domain under the name protonvpn[.]store. The Registrar used for this campaign is from Russia.

We have found that at least one of the infection vectors is through affiliation banners networks (Malvertising).

When the victim visits a counterfeit website and downloads a fake ProtonVPN installer for Windows, they receive a copy of the Azorult botnet implant. [.....]
