Press Release
Instant Messenger RootKit Worm Tied to Worldwide Bot Network Controlled by Group in Middle East
FaceTime Communications Warns Customers and Federal Authorities of New Threat
FOSTER CITY, CALIF - November 17, 2005 - Experts at FaceTime Security Labs™ ,
the threat research division of FaceTime Communications, identified and
reported a new threat today related to the AOL Instant Messenger (AIM)
"RootKit" worm they first identified on October 28, 2005. New research
completed on the AOL rootkit worm confirms it acts as a back door for
additional malware to be downloaded. The additional malware is capable of
stealing usernames, passwords, and other personal information, and can be
managed and controlled by a hacker through IRC communication sessions.
FaceTime security researchers confirmed that computers infected with the
lockx.exe rootkit file are being further compromised by a group in the Middle
East. The attackers have compromised multiple servers hosted by ISPs worldwide
to distribute the malware payload. The additional malware includes a "ster.exe"
file that contains six additional files to provide the attacker with the
capability to upload, download, and monitor the infected host PC. It has also
been found that the malware has the potential to steal Microsoft Outlook
Express email passwords and log keystrokes. The infected computers can also be
used as a platform for launching attacks on Web sites or networks.
Who is affected: All users who have been infected by the 'lockx.exe"
rootkit or its variants are at most risk. Users of other messaging applications
may also be affected by the ster.exe payload as it can be distributed by the
lockx.exe infected PCs. All PC users can initiate a free online scan which can
detect and disable the lockx.exe file by visiting: www.facetime.com.
Additional Information:
-
The lockx.exe rootkit and its variants connect to an IRC server, where it is
capable of receiving instructions through private, automated messages from an
IRC operator. These messages can open a browser session or install an unwanted
application
-
Over 17,000 users were found to be compromised on a single server, and multiple
servers exist worldwide
-
Users may receive the instant message text consisting of:
-
"evilday.us/pic####.com", or
-
"how do I look[ipaddress]/~q8army/pic0023.com" which links them to one of
multiple worldwide servers to deliver additional malware
-
Additional malware includes self-extracting zip files including a "Ster.exe"
file which utilizes the compromised machine to deliver multiple payloads that:
-
Can steal your browser auto-complete data which may leak confidential personal
information
-
Gain access to Microsoft Outlook Express
-
Open browsers to launch a denial of service attack, and/or
-
Download additional malicious applications
"We have delivered detailed research information to the U.S. federal
authorities and are fully cooperating with their efforts," said Kailash
Ambwani, president and CEO of FaceTime Communications. "This army of 'bots
could be used for any number of malicious purposes including a denial of
service (DoS) attack against targeted Web sites."
FaceTime Customers Can Prevent This Threat
FaceTime Enterprise Edition and IMAuditor customers can proactively block these
malicious threats and prevent infections before they happen by blocking
downloads of the specific executable files associated with the threat. FaceTime
also recommends activating the Day Zero Defense System within IMAuditor 6.5.
The system utilizes anomaly detection techniques to analyze multiple
characteristics of IM-borne worms and other malicious code against normal
behavior, and provides patent-pending protection against these threats without
the need for traditional security signatures. FaceTime RTGuardian customers are
automatically protected if they have auto update features enabled. FaceTime's
X-Cleaner customers (formerly XBlock) should download the latest update and
scan their PC to detect and remove lockx.exe files.
