The long road to your crypto: ClipBanker and its marathon infection chain

Threat actors are distributing a Trojan disguised as Proxifier software; through a multi-stage infection chain, it delivers ClipBanker – malware that replaces cryptocurrency wallet addresses in the clipboard.

At the start of the year, a certain Trojan caught our eye due to its incredibly long infection chain. In most cases, it kicks off with a web search for “Proxifier”. Proxifiers are speciaized software designed to tunnel traffic for programs that do not natively support proxy servers. They are a go-to for making sure these apps are functional within secured development environments. By coincidence, Proxifier is also a name for a proprietary proxifier developed by VentoByte, which is distributed under a paid license.

If you search for Proxifier (or a proxifier), one of the top results in popular search engines is a link to a GitHub repository. That’s exactly where the source of the primary infection lives. The GitHub project itself contains the source code for a rudimentary proxy service.
