UNC2717 is a threat cluster tracked for intrusions involving Pulse Connect Secure VPN appliances between October 2020 and March 2021. The actor targeted government agencies in Europe and the United States and used custom malware families including HARDPULSE, QUIETPULSE, and PULSEJUMP; reporting also observed RADIALPULSE in at least one UNC2717 intrusion. Operations relied on exploitation of multiple Pulse Secure vulnerabilities, including CVE-2021-22893 and previously disclosed flaws, to gain access to exposed appliances and establish durable footholds. UNC2717 demonstrated advanced tradecraft on compromised Pulse Secure devices, including deployment of appliance-resident malware and webshell capability, persistence mechanisms designed to survive software upgrades and factory resets, and anti-forensic measures such as timestamp manipulation and deletion or editing of logs and related artifacts. Activity associated with these Pulse appliance compromises included bypass of single-factor and multi-factor authentication protections, credential harvesting, and use of stolen credentials to access downstream enterprise resources. Broader investigations into the same campaign family also documented lateral movement from compromised VPN infrastructure into internal systems using common remote administration protocols and browser-based access, as well as evidence of data theft at multiple victim organizations. UNC2717 has been assessed as part of a broader set of Pulse Secure exploitation operations aligned with Chinese espionage activity, but available reporting specifically states there was insufficient evidence to determine UNC2717’s precise government sponsorship or affiliation with a previously named APT group. Its victimology and tradecraft are consistent with espionage-oriented objectives focused on long-term access to government networks.
