malware details first documented Cybersecurity researcher Will Thomas (@BushidoToken) queries IoT search engine Shodan in November 2022.

Titan is offered as a builder, allowing customers to customize the malware binary to include specific functionality and types of information to steal from the victim’s machine.

At runtime, the malware Hollow processing Injects a malicious payload into the memory of a legitimate process known as AppLaunch.exe, a Microsoft .NET ClickOnce launch utility.

Malware is normally propagated Via look-alike websites of popular software, the same domains are actively updated and host Trojan horse versions of various applications.

It has also been observed to artificially inflate executable sizes up to 260MB by adding random data to avoid detection by antivirus software, using a method known as padding.

The findings follow malware campaigns observed to deliver Raccoon and Vidar using hundreds of fake websites masquerading as legitimate software and games.

Team Cymru analysis Published earlier this month, “The Vidar operator has split their infrastructure into two parts: one dedicated to regular customers and one dedicated to the management team and potentially premium/important users. ”
