Fleetdeck
FleetDeck is a legitimate remote monitoring and management (RMM) / remote access tool that has been repurposed by cybercriminals in phishing and initial-access campaigns. Reported use cases in the provided content include platform-aware phishing in which a landing page fingerprinted victims and delivered FleetDeck to macOS users while delivering Tiflux RAT to Windows users. Proofpoint also observed increased use of FleetDeck in 2024-2025 as part of a broader shift toward legitimate RMM tools as first-stage payloads in email campaigns, alongside tools such as ScreenConnect and Atera. In these campaigns, RMM tooling is used to gain remote access, maintain persistence, perform reconnaissance, harvest credentials, enable lateral movement, support financial theft, and stage follow-on malware. FleetDeck was also observed in activity targeting trucking, freight, and logistics organizations, where threat actors used RMM and remote access tools including FleetDeck, ScreenConnect, SimpleHelp, PDQ Connect, N-able, and LogMeIn Resolve to gain initial access and persistent control; these intrusions were associated with cyber-enabled cargo theft and collaboration with organized crime groups. Additional reporting noted at least one low-volume threat cluster regularly using Bluetrait since October 2024 that also delivered FleetDeck with similar payment-themed lures and methods. The content does not provide FleetDeck-specific hashes or infrastructure, but it does characterize its delivery via phishing URLs and malicious executables/MSI installers in broader RMM campaigns.
