Dangerous Trojan Disables PC AV Protection, Turns Infected Computers into Zombies. Outbreak Filters Protects Users 21 hours and 59 minutes Before First AV Signature

Background

IronPort's Virus Outbreak Filters protects customers within the critical period between the first exploit of a virus outbreak and the release of an AV signature. During the recent Feebs variant outbreak, Outbreak Filters protected customers 21 hours and 59 minutes before traditional AV vendors** provided protection.

Potential Damage from Outbreak

FeebDI-Q is a dangerous Trojan that spreads by telling users to open an attachment that contains a private message. Once opened, the Trojan disables desktop AV programs and 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.
