Dangerous Trojan Masked as a Kodak Photo Outbreak Filters Protects Users 16 hours and 27 minutes Before First AV Signature

During the recent Trojan variant outbreak, Outbreak Filters protected customers 16 hours and 27 minutes before traditional AV vendors** provided protection.

Potential Damage from Outbreak

Troj/Dloadr-AMJ is a dangerous Trojan that was recently spammed out as a spoofed message asking users to open a photo in a zipped document. Once opened, the Trojan opens a backdoor that remote hackers can use to take over the computer. Once taken over, hackers can use the computer to send spam and host spyware. Remote hackers can also install key loggers and screen scrapers onto the infected PC to steal personal, confidential and financial information without the user's knowledge.
