GootLoader Malware Uses 500–1,000 Concatenated ZIP Archives to Evade Detection

The malware exploits the default Windows unarchiver, delivering JavaScript payloads that can lead to ransomware. Recent campaigns have introduced further obfuscation, such as custom WOFF2 fonts and exploiting WordPress endpoints.
