In October 2025, phishing emails predominantly delivered Trojan malware via attachments, accounting for 47% of cases. These attachments included scripts, documents, and compressed files, notably RAR archives containing JavaScript files. The phishing campaigns also involved distribution of Remcos RAT malware and used document attachments to download additional payloads. Korean phishing emails were specifically analyzed, revealing targeted case names, subjects, and attachment filenames. The report highlights evolving tactics such as increased use of compressed JS files and exploitation of OLE objects within documents. The threat leverages multiple MITRE ATT&CK techniques including persistence, command execution, and credential access. This medium-severity campaign poses significant risks through social engineering and malware delivery via email attachments, requiring focused defensive measures. No known exploits in the wild are reported, but the widespread use of common file formats and compression methods increases the attack surface. European organizations should be vigilant against these evolving phishing tactics and malware payloads.
