The Z2FA_LTS phishing kit represents a sophisticated cyber threat associated with the Sidewinder APT, targeting governmental entities in South Asia, including the Bangladesh Navy and Pakistan's Ministry of Foreign Affairs. The phishing operation leverages a polished Zimbra webmail clone, designed to harvest user credentials through a highly deceptive interface. The kit's architecture includes server-rendered pages using Express.js, deploying on Cloudflare Workers, which has proven effective for evading detection.
