SloppyLemming, also known as Sloppy Lemming, Outrider Tiger, and Fishing Elephant, is an India-linked cyber-espionage threat actor active since at least 2022. Its operations focus primarily on Pakistan, with additional targeting in Bangladesh, Sri Lanka, Nepal, China, and Indonesia. Targets include government agencies, law enforcement, military and defense organizations, nuclear regulatory bodies, energy operators, telecommunications providers, technology companies, transportation and logistics organizations, financial institutions, and academic organizations. Its intelligence-collection priorities align with Indian strategic interests, although a specific sponsoring agency has not been established. The actor uses tailored spear-phishing, impersonated government and webmail services, credential harvesting, and Google OAuth token theft to access intelligence-relevant accounts. Its custom CloudPhish toolkit creates fraudulent webmail login pages using Cloudflare Workers and exfiltrates captured credentials through Discord. SloppyLemming also automates access to compromised mailboxes and downloads messages and attachments. It extensively abuses legitimate cloud services for payload delivery, command and control, and exfiltration. Malware delivery techniques include PDF lures, macro-enabled Excel documents, ClickOnce application manifests, WebDAV-based delivery, and DLL side-loading through legitimate Microsoft executables. Its tooling includes Cobalt Strike, Havoc, NekroWire, BurrowShell, and a Rust-based keylogger and remote-access trojan. BurrowShell supports remote command execution, file manipulation, screenshot capture, and SOCKS proxy tunneling, while disguising command-and-control traffic as Windows Update communications. The Rust tooling adds keylogging, persistence, port scanning, and network enumeration. Other evasion techniques include encrypted payloads, in-memory execution, and dynamic API resolution. Despite increasingly elaborate execution chains and expanded cloud infrastructure, the actor has repeatedly exposed tools and staged payloads through operational-security failures, including open directories.
