is a malicious archive associated with a sophisticated spear-phishing campaign targeting high-profile organizations .

: The loader communicates with a Command and Control (C2) server to download the final stage, which is often a modular malware variant capable of: Exfiltrating browser credentials and cookies.

: Often uses a double extension (e.g., Project_Specs.pdf.lnk ) and executes a hidden command that launches mshta.exe or powershell.exe to run a remote script. : The loader communicates with a Command and
: The scripts inside the archive are frequently layered with Base64 encoding, XOR encryption, and junk code to hinder static analysis by antivirus engines.
To protect against threats delivered via files like DAHALO.rar , organizations should:
: The malware often creates a scheduled task or modifies registry run keys (e.g., HKCU\Software\Microsoft\Windows\CurrentVersion\Run ) to ensure it remains active after a system reboot.
