TraderTraitor ROOFDECK command-and-control servers and FLATROOF stagers (Lazarus)
Command-and-control servers of the ROOFDECK backdoor and delivery hosts of the FLATROOF loader, malware that vendors attribute to TraderTraitor, a North Korean Lazarus Group cluster that goes after cryptocurrency and cloud engineering staff with fake job tests and trojanized developer tools such as a malicious Terraform provider. The ROOFDECK servers present TLS certificates from a private mkcert development certificate authority whose name carries the operator's machine name, and answer unknown paths with a short JSON 'Not Found'. FLATROOF downloads its next stage disguised as web font files from a look-alike HashiCorp domain, a dynamic-DNS host, a GitHub repository and a Vercel project. A match means a scan of one of these servers or hosts, or a page that contacted one.
