ZPHP

Also known asZPHP

ZPHP is a Proofpoint-tracked threat cluster first identified in June 2023. Proofpoint describes it as conducting fake browser update campaigns that lead to NetSupport RAT, with activity ongoing in weekly campaigns. Proofpoint observed that beginning in June 2024, ZPHP campaigns used a NetSupport configuration with licensee XMLCTL and serial number NSM303008. Proofpoint also noted overlap between ZPHP and UAC-0050 in similar JavaScript-based delivery mechanisms and overlapping NetSupport configuration, but explicitly stated that this overlap does not necessarily demonstrate they are the same actor. Alias: zphp.
