Outrider Tiger
Outrider Tiger is an India-linked espionage threat actor referenced as connected to the cluster dubbed Sloppy Lemming and also associated by researchers with Fishing Elephant. Reported targeting includes nuclear-regulatory organizations, defense firms, and critical infrastructure in Pakistan and Bangladesh, with Arctic Wolf additionally assessing a focus on nuclear, defense, logistics, and telecommunications providers. Observed tradecraft includes phishing- and credential-theft-centric intrusion activity, including a PDF lure that redirects victims and a macro-enabled Excel delivery chain that drops a Rust-based keylogger. The actor has been described as evolving from use of Cobalt Strike and Havoc C2 toward custom tooling written in Rust, while expanding cloud-based command-and-control infrastructure through Cloudflare Workers. The reporting also notes operational security mistakes on some C2 infrastructure, including open directories that allowed researcher access. Alias explicitly mentioned in the provided content: Sloppy Lemming; the content also states it is connected to Fishing Elephant.
