Unfading Sea Haze attacks start with spear-phishing emails carrying malicious ZIP archives that contain LNK files disguised as documents.
In earlier attacks, the hacker also used Ps2dllLoader, a tool that loads.
Interestingly, a custom tool checks for newly plugged USB and Windows Portable Devices every ten seconds and sends device details and specific files to the attackers.
To exfiltrate data from breached systems, Unfading Sea Haze uses a custom tool named 'DustyExfilTool' that performs secure data extraction via TLS over TCP. More recent attacks show that the threat actors have switched to a curl utility and the FTP protocol for data exfiltration, now also using dynamically generated credentials that are changed frequently.
Unfading Sea Haze shows stealth, persistence, and adaptability, leveraging fileless attacks, advanced evasion methods, and modular malware design.
