ZPHP

ZPHP is a cybercriminal threat cluster tracked for fake browser update campaigns that deliver NetSupport RAT. The activity has been observed since at least June 2023 and has continued with frequent recurring campaigns. ZPHP is part of the broader criminal ecosystem that abuses web injects and fake update lures to trick users into installing malware, a technique that expanded beyond early pioneers such as TA569 and became common across multiple clusters. ZPHP is associated with JavaScript-based delivery mechanisms and fake update workflows that lead to remote access malware installation. Its campaigns have been specifically linked to NetSupport RAT, indicating capability for initial access, persistence, remote control, and follow-on post-compromise activity. Reporting also notes overlap in NetSupport configuration and similar JavaScript delivery patterns between ZPHP and UAC-0050, although that overlap alone does not establish that they are the same actor. Available information supports classifying ZPHP as a financially motivated cybercriminal cluster involved in malware delivery and initial access operations. High-confidence public reporting in the supplied material does not attribute ZPHP to a specific country, does not identify confirmed victim countries, and does not establish ransomware or extortion operations directly conducted by the cluster.
