Technical Analysis of Zloader Updates www.zscaler.com/blogs/sec…

Zloader (a.k.a. Terdot, DELoader, or Silent Night) is a Zeus-based modular trojan that emerged in 2015. Zloader was originally designed to facilitate banking, but has since been repurposed for initial access, providing an entry point into corporate environments for the deployment of ransomware. Following an almost two-year hiatus, Zloader reemerged in September 2023 with significant enhancements to its obfuscation techniques, domain generation algorithm (DGA), anti-analysis techniques and network communication, along with a stealthier approach to infections.
