The holidays had come and gone but malware hitching on holiday cheer still persists. Trend Micro recently detected TROJ_DLOADER.IAR riding as attachment to spammed email messages. It arrives as a ZIP archive that contains the file FLASH_HAPPY_NEW_YEAR.EXE.
This Trojan modifies the HOSTS file and downloads other possibly malicious files onto affected computers. As of this writing, however, its download URLs are unavailable.
