Rugmi is a loader ecosystem associated with affiliate-delivered social-engineering campaigns that distribute information-stealing malware, including DeerStealer. Observed operations have used trojanized software bundles and deceptive installers that present legitimate applications as decoys while covertly extracting and launching malicious components. In documented activity, a weaponized loader abused a repurposed legitimate download engine component, decrypted an embedded configuration and payload, and executed DeerStealer fully in memory to reduce on-disk exposure. Activity linked to the Rugmi ecosystem has supported credential and session theft at scale. Delivered DeerStealer payloads have targeted browser-stored passwords, cookies, autofill data, payment-card data, browsing history, cryptocurrency wallets, browser extensions, messaging and collaboration sessions, VPN material, and file-transfer credentials. Post-compromise functionality has included hidden remote desktop surveillance through VNC, keylogging, local staging of stolen data, encrypted exfiltration over HTTPS, and persistence via user-run autoruns and scheduled tasks. Tradecraft reflected defense evasion through obfuscation, in-memory decryption and execution, and masquerading of malicious DLLs as legitimate software components. Rugmi appears to function as part of a cybercriminal distribution ecosystem rather than a nation-state intrusion set. The observed use of DeerStealer MaaS through an affiliate-operated campaign indicates a financially motivated access-and-delivery role focused on malware distribution, credential theft, session hijacking, surveillance, and data exfiltration.
